Buyer guides
Buying methanol
How methanol is specified and graded, what to ask a supplier, and how to make sure the quotes you receive are actually comparable.
Most methanol purchases go wrong in the enquiry rather than the delivery. A buyer who names the substance but not the specification gets quoted against whatever the supplier assumes; a buyer who asks for a price without stating pack format and volume gets a number that cannot be compared with anyone else's. Neither is difficult to avoid, but both are common enough that suppliers expect them.
These guides cover the buying process itself: how methanol is graded and specified, what a certificate of analysis actually tells you, how to assess a supplier beyond the price they quote, and what to expect on order quantities, lead times and switching. They assume you know what you want the methanol for and need to know how to go and get it.
Key points
- Name a reference specification in the enquiry — IMPCA, Grade AA, a pharmacopoeial monograph, or an analytical grade. “Methanol” alone is not a specification.
- Ask for a batch-specific certificate of analysis, not a generic product datasheet. One is a document you can hold a supplier to; the other is marketing.
- State pack format, annual volume and delivery postcode in the first email. Without all three, quotes are not comparable.
- The cheapest quote is frequently the one that has assumed a lower grade than you need. Compare specifications before comparing prices.
- Supply security matters more than most buyers price it at. Ask how many sourcing routes a supplier has before you need to know.

The end-to-end process, from working out what you need to receiving the first delivery.
Methanol grades explained
IMPCA, Grade AA, technical, HPLC and pharmacopoeial grades — what separates them and what each is for.
The IMPCA reference specification
The global bulk trade standard, its actual limits, and what buying against it does and does not guarantee.
Reading a certificate of analysis
Which figures matter, which are noise, and what to do when a CoA and a specification disagree.
Choosing a methanol supplier
Assessing capability, sourcing routes, technical support and emergency arrangements — not just price.
Order quantities and lead times
Typical minimums by pack format, what drives lead time, and when quarter-end affects availability.
Switching methanol supplier
Requalifying a new source, managing container liability and running a changeover without a supply gap.
What a good enquiry contains
A supplier receiving a well-formed enquiry can quote accurately the same day. One receiving a vague enquiry either asks three rounds of questions or guesses — and a guess in your favour is rarer than a guess in theirs. Everything below fits in one email.
- The named specification. Not the application, not the substance alone. If you genuinely do not know which grade you need, say what the material is for and ask the supplier to recommend one in writing.
- Pack format and volume. Both per-delivery and annual. Annual volume is what determines whether you are quoted a spot price or offered a contract.
- Delivery postcode and site constraints. Access limitations, vehicle size restrictions and offloading arrangements. This is cheaper to raise now than to discover on the day.
- Any impurity limits tighter than the standard specification. These change the price and sometimes the available sources, so they belong in the first email rather than the third.
- Whether you need a low-carbon claim. Certified bio-methanol or e-methanol is a different supply chain at a different price. Ask for it explicitly or you will be quoted conventional product.
Ask for the GB-format safety data sheet first. A supplier who cannot produce a current one promptly is telling you something about how they will behave when a delivery goes wrong — and you need it for your own COSHH assessment regardless.
