GMP Audit Consulting Services

What is GMP Audit for Suppliers of Costco?

Good Manufacturing Practice (GMP) is a system for ensuring that products are consistently produced and controlled according to set quality standards.

It is designed to minimize the risks involved in any company’s production that cannot be eliminated through testing the final product.

All facilities that process, pack, warehouse, or distribute consumable products or supply food-contact packaging materials to Costco Wholesale Corporation are required to complete an annual third-party Non-Food GMP audit. 

Costco approved third-party GMP audit companies contact suppliers to schedule audits within the specified timeframe.
