Buyer guide · Supplier due diligence

Use this checklist to organize a supplier conversation before requesting a wholesale quotation. It is intended for research-use procurement and does not make medical or therapeutic claims.

1. Product and specification

Product name, code and physical form

Available pack sizes and packaging format

Batch documentation and stated analytical methods

Storage and handling information supplied with the product

2. Commercial terms

Minimum order quantity and sample policy

Quotation validity and payment terms

Production or preparation lead time

Replacement process for documented shipping damage or discrepancy

3. Documentation

COA or batch report linked to the supplied batch

Product and package labels that match the order

Commercial invoice and packing list

Shipping and customs documents where applicable

4. OEM and private-label questions

Label and packaging formats available

Artwork review and approval process

MOQ for custom packaging

Lead time for a repeat order

5. Communication and verification

Use a business email, keep the quotation and documentation together, and ask for clarification when product names, batch numbers or test details do not match. A clear supplier should be able to explain what is included in a quotation and which documents are available.
