1. Introduction
International trade in potato flakes and potato powder requires compliance with multiple regulatory frameworks. Buyers in different markets reference distinct standards for food safety, quality parameters, labeling, and permissible additives.

5.2 CIQ Export Inspection (China)
For export of potato flakes from China:
- Pre-export inspection by local CIQ office
- Sample analysis — full parameter testing at CNAS-accredited lab
- Health Certificate issuance (Chinese + English bilingual format)
- Phytosanitary Certificate from General Administration of Customs (GAC)
- Certificate of Origin (for preferential tariff treatment under Free Trade Agreements)

7. Convergence Efforts and Future Trends
International harmonization of potato product standards is progressing through several channels:
- Codex Alimentarius revisions — CXS 214-1999 is under periodic review to reduce divergence between national standards
- China's GB standards modernization — The 2023–2025 revision cycle for GB/T 31736 aims to align microbiological limits with Codex/EU norms
- Mutual recognition agreements — China-EU Geographical Indications agreement (2021) and potential future food safety MRAs
- GFSI benchmarked schemes — Increasing adoption of BRCGS, FSSC 22000, and SQF by Chinese exporters to bridge gap with international customer expectations
