What Documents Should Buyers Request for PS Ingredients?

For PS ingredient sourcing, buyers commonly request specification sheets, COA, production license evidence, packaging information, test methods, and any market-specific compliance documents.

Documents should be current, tied to the exact product being quoted, and reviewed before samples or bulk purchase.

Buyers should request current files from the sales team and confirm that each document matches the product, source, batch, and destination market.
