分析证书（COA）——HONGJI 马铃薯片

Official Batch Quality Test Report for Industrial Potato Flakes

The 分析证书（COA） is an official quality assurance document issued by 红吉农业 for a specific production batch of potato flakes. It provides laboratory test results demonstrating that the finished product meets established quality specifications before shipment.

Each COA is generated after production and quality verification, allowing customers to confirm that the supplied product complies with agreed technical requirements, food safety standards, and internal quality control procedures.

The document serves as an important part of HONGJI Agriculture's Quality Management System (QMS) and Food Safety Management System (FSMS), supporting product traceability, supplier qualification, and customer quality assurance.
