## What this rule covers
Sellers are responsible for ensuring that products are genuine and obtained through a legitimate supply chain. Amazon may request documents when authenticity is questioned.
## Why sellers should care
Authenticity complaints can affect listings, selling privileges, and funds. Evidence collected after a complaint is often weaker than records retained from the start.
## Safer operating practice
Keep invoices, supplier details, product identifiers, purchase dates, and quantity records in an ASIN-level file. Verify that documents describe the actual product and business entity involved.
## Important note
Amazon decides whether submitted evidence is sufficient. This guide does not validate suppliers or guarantee an appeal outcome.
