Why is Chemsavers comfortable with shipping chemicals to residential addresses, but sigma/fisher/TCI/etc are not?

Cou - 5-11-2020 at 21:02

My guess is that companies like Chemsavers are essentially retailers, in that they are smaller companies that have time to review orders more closely. They can review every individual order to check if you are ordering benign chemicals, or something suspicious.

No chemical supplier wants to appear on the news with their logo on reagent bottles in a drug lab bust.

Yeah if someone is just ordering some 1-pentanol, there's obviously nothing clandestine and drug-related they can do with that. It's only a couple times more toxic than 190 proof everclear.

On the other hand, if someone has a purchase history of both red P and iodine, they have the time to check what you have ordered, and refuse order and/or ban you as a customer.

I don't understand the "liability" thing. Sigma refuses to sell sodium chloride to individuals, but Dollar General sells sh*t in the cleaning section that would kill a child who drank it. I think it's more an issue of whether or not the business is a retailer that has time to review orders and check what customers are ordering.

TL;DR; Sigma Aldrich doesn't have time to check if your order is for sodium chloride or ephedrine.

I tried to order from Fisher Benelux with company account but our company was registered in a residential are, so they wrote me:

" We have been advised that: due to the nature of the products we sell , we are unable to supply to companies that are registered in residential areas. We will not be able to supply your order."

Also it was interesting situation with Duran (Life Science) sales, I asked to point me to some retailer of their product who can sell to individuals and if there is no one I proposed to become their retailer, had many conversation with them but finally they said me that "don't want to sell their glassware to individuals due to dangerous nature of these things ".

Selling to an individual is very different to selling to a corporation. The likes of Sigma have invested huge amounts of cash to be the perfect chemical selling machine to corporations and they do it exceptionally well. Changing that model costs money and they will only do that if they see more profit. Selling to individuals that will often be budget constraints did not offer up a significant revenue stream so they ignore it

In this regard I completely don't understand frequent appearance of bottles of this particular brand on many hobby-style/amateur chemistry/popular science youtube channels.

Big thanks to those youtubers who don't support those who don't support us!

There are some resellers, who can obtain chemicals from Sigma, Carl Roth, Merck, and so on, who do sell to individuals. E.g. look at Labstuff in NL. This company can order chemicals from the big companies. He asks the price of those chemicals, plus a small fee for himself (I remember that it is appr. 1 euro per chemical). He combines many orders from private customers to make big orders at the big companies (they usually have a lower limit on the total value of an order and some of them also have a flat starting fee for orders, so that it is more economical to order for a high total value).

teodor - 6-11-2020 at 03:23

@woelen I know about this company but it always was the case I checked their catalogue and didn't find what I need. Like now, I need a sodium metal, and this is not particular rare chemical, but they have no it. So, I would prefer to put the order to s3chemicals or onyxmet, and for common staff labshop.nl is the best for me, the last has even more limited catalogue but everything will be delivered from stock next day.
If it is the case I can write to labstuff and ask something they don't have on their site it would be interesting, if so - thanks for the information.

Edit: I have the impression that less chemicals are available on ebay now than 1 year ago. For example, for sodium there is only one position and price is high, also the nearest is in UK ... I don't find much sells of chemicals in old bottles like 30 years old stocks ... Is it something that changed or just I have wrong observation?

Aslo I am aware about people who claim they can sell chemicals but you should make request to them. I think it is great but for some reason doesn't work for me - I feel myself more comfortable with catalogue where I can see the availability, price per quantity, delivery time & price etc etc, so I can easily compose a big request for my current and future needs which fits in my budget and I definitely know when it come, so I can well plan my experiments. So, those nice sellers are in different category than ordinary internet shops with a basket.

There are literally only a couple resellers in the USA at the moment. I think it's just very low demand. 2 resellers is enough to meet demand for the entire nation. If one of them disappears, someone else will fill the gap.

Texium - 6-11-2020 at 08:07

Another way that big-label chemicals sometimes end up in home labs is secondhand. I have many bottles of chemicals, mostly very specialized stuff from Sigma, that were originally from a university lab, but were not wanted and put up for grabs.

I also think there are less chemical items on eBay. There were several Polish sellers a few years ago, who sold all kinds of chemicals, frequently from old stock. They have gone. Things come with waves on eBay. Probably they have been more strict in the last few months and then slowly things get more lax again and more interesting offers appear again. But then, someone thinks it is too much, and then suddenly listed items disappear again.

I also like it better if I can order things from a shop, but sometimes it really is useful to contact people, who sell materials on sciencemadness. I have done this three times (with different people) in total and it yielded me nice quantities of NaBH4, NaBF4, As2O3 and HClO4. All hard to get chemicals, for decent prices in decent quantities (no need to buy at least a few kilos or something like that, but affordable, so that it also is not limited to just a few grams).

It might not be strictly related to liability. Large companies often don't want to deal with small orders due overhead costs that are fixed or don't scale linearly. It's a lot faster and more efficient to process and ship a large order to one customer for $5-10k versus several small orders to several customers for $5-10k.

[Edited on 11-6-2020 by monolithic]

Fyndium - 6-11-2020 at 09:43

Money and liability. Private sales have returning rights and other stuff, and common order is like 30 dollars + shipping, while a company or institution may slam a $10k order. Doesn't just pay off to deal with privates.

Oh really? I found that my average spending per one order is much more.

Also, when I tried to open account on Fisher I filled how much my company plan to spend each month for chemicals. Also I proposed them solution to get parcels on different address if the address of company registration is a problem. But I think they were clear about the reason in the response.

Yes but your orders are still tiny and sporadic compared to the large and repeated orders of a pharma company or a university. Also consider how "the systems" of a chemical supplier are set up. Individuals typically want to pay by credit card or PayPal which have % processing fees, if these suppliers even have these payment methods available. Institutions pay via ACH, wire, or checks, which are closer to flat fee. Again, variable fee on large numbers of small dollar value orders (plus employee overhead in paying someone to manage these payments and the headaches associated with PayPal/credit card chargebacks) versus relatively fixed fees on small numbers of large dollar value orders that flow through a bank account in an order manner. It's kind of the same reason why no one would even try to buy paper towels or shampoo from Procter & Gamble unless they're in the inventory purchasing department of WalMart, because it's unlikely P&G even has the payment processing systems in place to deal with consumer-level purchases, much less the desire to deal with consumer-level purchases.

teodor - 6-11-2020 at 11:51

@monolithic, there is some known method to make revenue on small orders - selling by catalogue, when the price per kg dramatically raise when you buy smaller quantity. To name only one company which very successful uses this approach to sell electronic components for decades I can name Farnell. It is very close to selling chemicals because the assortment is wide as well also there are various restrictions in selling e.g. military precision components etc to some countries and so on.
So, why they can use this model and supply big producing companies, R&D, repair shops as well as individuals very well but chemical suppliers had failed?

My guess is that there is more of a precedence for selling electronics to amateurs than there is for selling chemicals to amateurs. So quantifiable factors (SG&A expense) plus less quantifiable / more qualitative factors (brand/reputation liability, precedence, etc.) rolled up into a loose "return on investment" analysis: they don't think it's worth their time to sell to amateurs, for a number of reasons. I really don't agree with it, and I am thankful for companies like ChemSavers, but I can understand "some" aspects of it since I deal with B2B transactions professionally.

teodor - 6-11-2020 at 13:04

No, Farnell biggest part of the market is not amateurs. I worked with them as a kind of a local distributor, and their market were companies, but their business model doesn't create problems to sell to amateurs. Because even a big plant can buy some components in very small quantities, let say, to repair their production line they need 1 piece but they buy 10 for future. So, the order size is not dependent on the company. It was amazing to get one order from spacecraft development department from Moscow and the next one from amateur building Hi-Fi amplifier in Belarus (their orders were quite comparable by size). And their model allowed to support both R&D and future mass production of systems.
Also I worked (in the Netherlands) 2 years as a developer of logistic systems (I didn't like that because I have specialisation as a system programmer, but it was some period in my life), so I know what modern warehouses, order processing, logistics really are - they are 90% automatised, even packing an order into a box now in more and more case are performed by robotics devices. The only 2 problems we were limited by - a tricky packing (like when you want to fit one additional pencil into the box full of paper using available holes, and we had a client who wanted it, and this possibility of packing was calculated by system) and combining normal shop/warehouse operations and internet ordering in the same logistic system (people from NL know what Jumbo supermarket is - one of our clients). So, I don't know what is the additional cost of processing more orders if you can get any revenue from that. Well, in Christmas time we had some more work to monitor the system performance.

Texium - 6-11-2020 at 14:27

That’s all well and good, but there are still fundamental difference between selling electronics and chemicals to hobbyists:

1. There are a lot more amateur electronics hobbyists than amateur chemists

2. Amateur electronics has been more widely accepted by society

3. There is no potential liability with selling electronic components to individuals, unless they use them to build a bomb, but even then, the scrutiny generally isn’t on “how were they able to acquire all of these electrical components?” It’s always “how did they get/make the explosives?”

4. Electronic components are easy and inexpensive to ship. Many chemicals require expensive HazMat shipping which makes small quantities of such chemicals exorbitantly expensive.

5. There are codes and regulations for storing some chemicals. Individuals, while they may handle their chemicals safely, are not likely to follow local fire codes and other regulations to the letter, and this becomes another potential source of liability. Electronic component sellers don’t need to worry about whether you’re keeping your diodes and resistors stored separately, or whether your capacitors are stored in a locked, fire-proof cabinet.

6. There are many non-hobbyist uses for electronic components too: primarily in automotive repair and home improvement.

Well, if labstuff.nl only adds a fee of around 1€ per chemical...
S3 adds a fee of around 12€ per chemical.

If the former will, just as the latter, get you everything you demand from the suppliers of your choice, it doesn't sound that bad to me.
I know I got lots of quite critical things from S3 over the years, always friendly, always helpful.
But the fee per each chemical is still a little bit offturning to me.

Fyndium - 6-11-2020 at 17:42

Funny thing that every single package that has been opened by the customs for me has contained electronic components.

I think 12$ per item is not a bad thing if they really get you basically the full catalogue. Just order a bit more to compensate. They probably cover some of their own costs with that too.

What I wonder if big chem firms would stop shipping to certain companies because they retail their items to private consumers. I would see that Sigma wouldn't like that S3 drop-ships their precious stuff to anyone. At least Fischer and some other have actually a condition in their agreement forms that the items they supply must not be resold either to anyone or to private persons.

Cou - 6-11-2020 at 18:14

It really sucks that they try to make it hard for an individual with spare income to play around with chemicals for fun


Like, sometimes I see a fun reaction in the Journal of Organic Chemistry and I just want to do it myself, just because its fun. A professor is not gonna spend their grant money for me to dick around with chemicals for the hell of it.

If I had a big chemical business, then I could do the hobby on the side, but I haven't started a lucrative business.

[Edited on 11-7-2020 by Cou]

karlos³ - 6-11-2020 at 18:32

I don't think they offer that in general to every customer, you need to have a history with them.
At least something along those lines, as they have told me when they started such a program for commercial customers.

And no, 12€ isn't that bad, but 1€ would be preferred of course :D
It still doesn't match up if you buy a dozen of items already having a low price, and you don't even require the small quantities you are going to purchase.
Thats sometimes up to twice as much of the usual price just in fees.
That really makes you consider checking with one of the reputable sellers on here instead.

teodor - 7-11-2020 at 04:26

I agree with you, @Texium and think you have mentioned all the important point, so now we have a list of important pecularities. But the next question, why we have these:

6. There are many non-hobbyist uses for electronic components too: primarily in automotive repair and home improvement.


Point 3 and 6 are something we need to define better, I think.

You know, the history of chemical misusing is very old. As one example King Alexander II of Russia was killed by home-made bomb in 1879. But before the very last period nobody asked the question "how were they able to acquire all of these chemicals?". So, I think it is already consequence of the state when unavailability of chemicals is considered as a normal state.

And 6. Why and when pure chemicals were stopped to use? I remember the time when every educated enough family in SU bought bare, pure chemicals for doing something like photography, gardening, household needs (still have several books with recipes of solution for things like change property of wood, cloth, destroying spots etc etc) and electronics & metalworking & art as well not to mention nice chemical demonstrations for children. And today we have no less application for chemicals than for electronic components. It is just something else.

There is this eco boom where everything must be 100% natural. There is a hardware/interior store chain that sells their own brand stuff and while it's not at all organic store stylish, all their products are riddled with something that is of organic origin and "free of any chemicals". Solvents and paints are of some macabre polymer mixtures, cleansing agents are made out of wood soap and more of those very eco-polymers and surfactants, etc.

What annoys the * out of me is that all consumer products tend to be diluted to the extent they barely work. This is called business on the other hand, but the consumer ends up paying several hundred bucks per liter of some common cleansing agent. I'd rather buy 99% concentration of stuff and dilute it by the need than purchase already diluted crap. And this is the issue: people don't want to do anything themselves, they just want to buy everything ready as is.

There are exceptions, though. I once had an issue with toluene: at first I could not find it anywhere, then I found some diluted stuff that had about 25% of toluene - and then I found a 10 liter canister from hardware store that is basically a mixture of toluene and acetone in pure form, very easy to separate either the lazy way with water or the good way by distilling. All the other paint thinner products are made of some totally useless stuff.

About the general availability, I've indeed seen headlines about how could someone obtain something - oh well, it's sold in the hardware store by the canful but the trade name might not be the chemical name.

I would say that to check that something is free of hazardous chemicals one needs chemicals. To check that your soil is clean and good to grow what you want to grow you need chemicals. Relaying on brand, distribution network, devices made by somebody in china or where they were made but not on the self-evident knowledge is very dangerous tendency of society.
At the same time popularity of chemistry-related youtube channels is very big. Tell people how to test soil, how to test water, how to grow pure products with aquaponics and to do experiments with addition of different chemicals, minerals etc and observe the results.
So, I see no problem in this "biological" tendency for chemistry popularisation.

The problem is that most people care only about convenience. If they need to remove rust from something, they buy rust remover. If they need to clean their toilet they buy toilet cleaner, while they use sink cleaner for their sink, even if these contain the same chemicals! If they need fertilizer for different types of plants, they’ll buy several different blends of fertilizer, even if these contain the same three ingredients just in different ratios, with varying levels of filler. If they need to refill their car’s coolant, they buy premixed 50/50 antifreeze and water. Auto shops don’t even sell fully concentrated antifreeze anymore, because people are too lazy to dilute it themselves, and they can make more money selling them water. One of my favorites is “Low Odor” HCl. It’s just 10% HCl instead of the usual 31% concentration that is sold at home improvement and pool stores. And guess what: the more dilute stuff costs twice as much! At some point companies realized that they could make a lot more money selling a single product for every use instead of a few raw chemicals or basic mixtures that could be used for many purposes.

I use many of my raw chemicals for household applications. Glacial acetic acid, diluted to 30%, to remove hard water deposits from faucets. Ethyl acetate to clean off sticky label residue from items (works better than commercial “Goo Gone” products and the like). Sulfuric acid to open clogged drains. Citric acid to clean the dishwasher. 27% hydrogen peroxide that I bought at a pool store to freshen laundry. Who cares that is says “pool shock” on the label? It’s much cheaper than Oxy Clean and does the same job!

The average person doesn’t think, doesn’t want to think, about how to solve a problem, they just want to be handed the solution to their problem.

Nonetheless, while many are a farce, there are some proprietary mixtures that do a better job than a single chemical. Companies did put a lot of R&D time and money into developing their formulas. CLR Calcium Lime and Rust cleaner, for instance, which is a proprietary blend of lactic acid, surfactants, and other chemicals, I’ve found to work much better than acid alone for cleaning hard water scale off of sinks and tubs. As chemists we can look at the SDS for various consumer products though, and make a judgment of whether it looks like a legitimately useful product, or if it’s something overpriced and easily replicated using chemicals that we already own.

Necessity

MadHatter - 7-11-2020 at 10:01

Necessity is the mother of invention or adaptation.
Sometimes what's readily available doesn't work
well or at all. That's where us chemists come in.
We'll adapt, find or make something.

I found that most OTC degreasers aren't worth a
shit. The answer: 5% NaOH solution. 200 grams
of Red Devil Lye in a gallon of H2O. Fumes are
obnoxious as hell but works like a champ.

I found that most roach killers don't do a very
good job until I ran across some cheapass Combat
trays and then NO more roaches.

Bed bugs were the most frustrating. Every person
I talked to said "Call an exterminator". I did. 2 visits
from them and $1500 later same problem. Time
for some research. Bed bugs and termites are in the
same family. A gallon of Ortho Home Defense spray.
It didn't list bed bugs but it did list termites. No more
bed bugs. This is an adaptation.

Sometimes people don't want to spend the extra
money it takes to solve a problem. I finally convinced
my father that Rooto sulfuric acid is 1 of the best
drain cleaners on the market despite costing more
than most. Still available at Ace Hardware for $12.97
+tax for a half gallon.

I totally agree with you (everything you wrote). But the same argument could be applied to the electronics components market. It seams people don't need supply of them anymore, especially not-surface mounted ones. You can buy everything you need designed and assembled, isn't it? Also, it is more cheap to buy new equipment than to repair the old one. You don't need discrete transistors anymore. Everything could be done inside some proprietary IC with standard power supply. You even don't need separate transformers not to say about copper wire and ferrite cores, standard power supplies are so cheap.
But strange, we still have a full supply of electronic components available.

Why radio amateurs ever exist today? Whether Internet is not available? Facebook, Twitter? Why some need to build antena to get signal?

Are photos of Hubble and other professional telescopes are not enough? Why ever people build private observatories? Why ever does this exist?

Also there is a full set of optical components available from, e.g. https://www.edmundoptics.com/ . They sell to individuals. How many individuals need discrete lenses and prisms? But people in Edmund seams know better. Every few months I get a full catalogue from them (the only one thing I bought several years ago was a camel brush for optics cleaning).

So, the universal argument "people don't need" doesn't work anymore especially when the population going to 8 billions. If somebody says "I need this" this is already argument. Growing population means growing demand even based on the same percentage of those who needs. Let's say it another way: some countries don't think well about their future in the global market. And these types of restrictions will pay back after several years.

Fyndium,
Yet those same companies (e.g. target) load the shit they call all natural with CMIT/MIT chloro methyl isothiazolinone/methyl isothiazolinone Biocides which are known to cause conditions such as machinists dermatitis which was due to CMIT/MIT BIOCIDES in machining coolant! I had it until the EPA banned that coolant.

densest - 8-12-2020 at 14:14

I suggest reasons why chemicals are less and less available to the amateur or home-business chemist:

Fear. Schools teach less and less science. The less the general public understands about chemicals the greater the fear. That fear is fed by people with agendas not necessarily beneficial. Misinformation and disinformation is everywhere.

1) Laws. More and more restrictive laws are passed because of fear. The "war on drugs" has been a "war on individuals." Some companies have been able to outlaw other companies' products. Some laws do address real hazards but are usually very broadly written to cover too many cases.

In the US, at least, the legal system is a pervasive problem for vendors. Laws regulating chemicals are torturously complex, vary by locality, have severe penalties and are subject to arbitrary interpretation. It's very difficult if not impossible to observe all of them. Even if a vendor didn't break any laws the company can be shut down until the matter is resolved.

2) Liability lawsuits (at least in the US) can be enormously expensive even if the vendor is in no way responsible. They can put any but the largest/most influential company out of business. Insurers (very large $$$ companies) lobby for (1)

3) A widespread assumption that anyone not working for a large corporation is ignorant or, lately, malicious therefore dangerous.

4) Support costs. Corporate customers are assumed to be knowledgeable.

Large vendors of chemicals are not willing to take those risks.

That leads to:

On retail chemicals:

a) See above. Products become weaker and weaker or disappear entirely. The larger the company the less likely it will sell anything useful.

b) Companies make money from "convenience" packaged materials but not necessarily because of simple greed.

People often buy pre-packaged chemical mixtures because of "transaction cost". Modern life is very complex. For most people, the cost in time and effort to learn the details about chemicals, their hazards and their proper applications is far greater than the premium paid for the single-purpose product. Even chemists may not have time to research enough details to successfully compound something cheaper or better than the commercial product.

c) The continual turnover of "new compound X is less harmful or persistent than old compound Y" is sometimes actually justified. CH2Cl2 is disappearing - it's very useful but also quite toxic. It'll dissolve almost anything organic including the lipids in your cells...

Off topic: unrepairable goods - EU is trying to move the cost of vanishing landfills to manufacturers.

The key os that the companies that sell to individuals are mostly small LLCs or tiny companies, with few assets. So if they sell to someone who turns out to be a problem, any lawsuits are pointless, as they are not worth much, at least compared to Aldrich or Fisher. You notice, lots of people sue J & J, Monsanto/Bayer and big pharmas-how many people sue John Smith's one person company. Same way that people making meth rarely get fined by the EPA for their pollution or OSHA for unsafe work, as most don't have any money.

Combination of fear of u.s.a. 3letter agencies and douchebaggery

Yeah if someone is just ordering some 1-pentanol, there's obviously nothing clandestine and drug-related they can do with that.

It's a precursor to MDPV, though. I would say this serves as a pretty good example of how difficult it can be to know what's a precursor :P

Larger U.S. Chem houses, were always reluctant to sell to individuals. Well, perhaps not always, but they have been uninterested in supplying small accounts, for at least 50 years.

VWR and Aldrich have been more or less hostile, for ages. This is nothing new.

They were not especially friendly with the small college, I long ago worked for. Though our occasional orders, might have been for $10,000.00 or so, the scientific suppliers were not impressed... We were too small.

A short visit to the Aldrich website will show that they aren't especially interested in small sales. Prices for small quantities of reagents are very stiff indeed. Perhaps a hundred dollars per a single liter of solvent.

Buy a thousand bucks worth, however..... And, the price may drop to $10.00 per liter. A reasonable price, and in consonance with prices, I paid in the distant past.

At any rate, the problem of acquiring reagents is not new. In my locale, even in the heydays of home chemistry, there were only a few suppliers that welcomed amateur, or walk-in customers.

Chemsavers are great for minor items. They can source nasty things from all over but you'll eat the double shipment. They used to have a supplier that would drop ship, but that went away a few years back.

Funny thing, I'll get Fisher or Sigma bottles from them too. I'm told that big chem houses are just big importers since most chemicals are produced outside the USA. Also the restrictions on residential addresses seems linked to the carriers. God bless DHL and the international suppliers, they'll bring me almost anything.

Have you ever ordered anything physically dangerous (but legal) from overseas? Alibaba has some great prices and I have ordered a few innocuous chemicals from them with success. My biggest fear, however, is US Customs opening the package for inspection, as they sometimes do, and the package being mislabeled to trick customs, as the Alibaba sellers sometimes do, and then dealing with the fallout of some US Customs agent being poisoned by SOCl2 that was labeled as perfume (or something to that effect.)
