I manage purchasing for a 90-person specialty coatings manufacturer. That's roughly $1.2 million in orders a year, spread across 20 or 30 vendors. I report to both operations and finance, which means I hear about problems from every direction. When I first started handling chemical orders in 2020, I assumed this job was mostly matching specs to prices. You check the SDS, compare quotes, pick the lowest number that doesn't obviously fail. That approach lasted about a year, and it failed in an unglamorous way: a vendor delivered perfectly good material, but their invoicing was a mess. Finance rejected the expense report, and the shortfall came out of our budget. Not a dramatic catastrophe, just a $2,400 lesson that the price on the PO isn't the real cost of a transaction.
Now I look at the whole picture before buying anything. And I've come to believe, strongly, that you can't buy chemicals intelligently without understanding the company behind them. Price, purity, delivery dates—those are table stakes. The real due diligence is in the history, the claims, and the technical competence.
A Search Result Is a Supply Chain Clue
Last year, a colleague from legal asked, 'Have you ever googled Olin Chemical Corporation mesothelioma?' I hadn't. But when I did, I found a long electronic trail—articles, court filings, forum comments. Some of it was decades old. Some of it was still active. A few weeks later I saw another search phrase: Olin Mathieson Chemical Corporation ammo. Different subject, same instinct. People were looking for the company's manufacturing legacy.
Now, I'm not a historian. I'm not a lawyer. But I am the person who signs purchase orders. So I've learned to read those search results the way a credit manager reads a credit report. A company can have a complex past and still be a great supplier today. But the past usually shows up somewhere: in process changes, in product discontinuations, in compliance records, and yes, in litigation. If a supplier can't talk about that history in a clear way, I have to wonder what else they're not telling me.
Product Knowledge Is the Best Kind of Selling
The second thing I've learned is that the best suppliers educate you. They don't just take an order and disappear. They explain why their product behaves the way it does.
We buy epoxy resins—our customers sometimes call it epoxy plastic—and we buy powder coatings resins for our finishing line. I don't have a chemistry degree. I can't tell you about molecular structures or glass transition temperatures. But I can tell you when a supplier is dodging a question. When I ask about cure time, adhesion limits, or edge coverage, the supplier who can explain it in plain language is giving me something more valuable than a discount. They're giving me confidence. That's a form of education, and it saves us money downstream.
Once, I wanted to buy powder coatings resins from a new supplier to save some money. The spec sheet looked identical to our regular product. But the cure profile was different, and the first production run didn't stick the way it should. The supplier said 'it should work,' which became the three most expensive words in our monthly budget. From that day, I ask for a technical commitment in writing. Education, in this context, isn't just about learning; it's about protecting ourselves.
A few weeks ago, R&D asked me: 'What are the leading resins for buffer exchange?' I didn't know. So I called a supplier and asked for a simple breakdown. They explained that buffer exchange usually involves size exclusion chromatography resins, sometimes ion exchange resins, and occasionally mixed-mode resins. They also mentioned the scale and salt concentration as key decision factors. I still don't know what a resin's 'dynamic binding capacity' means, but now I know to ask for it. That's the kind of education that turns a vendor into a partner.
Claims Need Receipts
I've also started using regulatory guidance as a purchasing tool. The FTC's Green Guides (ftc.gov) require environmental claims like 'recyclable' to be backed by data and to be truthful in context. Sustainability claims matter in chemical buying, but they're often vague. So I ask: 'Show me the substantiation.' If a supplier can't back up an eco-friendly claim, I assume their other claims might be loose too.
One concrete piece: FTC says if a product is labeled 'recyclable,' consumers in at least 60% of the areas where the product is sold must have access to recycling programs. That's a measurable standard. When I buy chemicals, I ask similar things about VOC content, shelf life, and safety data. It's not about being difficult. It's about demanding evidence.
The 'I'm Just a Buyer' Excuse Doesn't Hold
I know there's an objection lining up: 'You're an office administrator, not a compliance officer. Do you really have time to research every supplier's history and every chemical claim?' The honest answer: I make time. Because the alternatives are worse. I remember the vendor who couldn't invoice properly, and the one whose powder coating resin failed in production. I've spent far too many hours explaining problems to a VP because I picked a supplier by price spreadsheet alone.
You don't have to do the research alone. Ask the supplier pointed questions. Use public search engines. Read the FTC guidelines. Pull up a company's product data sheets. That's not 'becoming an expert.' That's being an educated customer. And as our own sales team is fond of saying, educated customers make better decisions and are easier to work with.
So Here's My New Rule
So, five years in, I've changed my mind. Chemical buying isn't just a transaction. It's an exercise in signal-reading. When I look at a supplier like Olin, I don't stop at the product catalog. I look at the public history—including the difficult parts—and I ask what they're doing now. I ask for technical education. I ask for substantiation. And the supplier who answers with evidence earns my trust.
I'd rather spend ten minutes explaining why I need that evidence than spend a quarter explaining why our department ate a $2,400 mistake. An informed buyer is more work to sell to. But the good sales reps know that the informed buyer is the one who comes back.
