Buyer guide

What a research-material file should contain.

A consistent buyer checklist makes a technical quotation easier to compare and audit.

Six checks

Move from a catalogue code to a documented order.

Each check answers a different question.

01 / Material

Exact identity

Code, name, strength, grade, pack and the current specification.

02 / Lot

Batch evidence

Confirm whether the COA is representative or linked to the quoted lot.

03 / Review

Analytical scope

Check the methods, limits and whether independent testing is required.

04 / Market

Destination rules

Review import, possession and intended-use requirements.

05 / Money

Commercial chain

Compare seller, contract, invoice and payment beneficiary.

06 / Receipt

Keep the record

Store the approved specification, documents, packing list and released pack.

Questions that should be answered in writing

What exact material and specification are included in the quotation?
Which analytical document applies to the quoted lot?
Are there independent tests, and what is their scope?
Who is the legal seller on the contract and invoice?
What destination-market review is required before order acceptance?
What happens if the product, quantity or packaging changes?

Pause on mismatches. If the product code, lot, seller or payment instruction changes, ask for a written explanation and verify through an independent known contact route.
