On June 22, 2026, China's General Administration of Customs (GACC) released its list of non-compliant imported food products for May 2026. A total of 706 batches from 43 countries and regions were denied entry, representing a month-on-month increase of approximately 52% (up 243 batches from 463 in March 2026) and a year-on-year increase of about 65% (up 278 batches from 428 in the same period last year).
The rejected shipments spanned a wide array of categories, including dairy, vegetable oils, alcoholic beverages, frozen livestock and seafood, snacks, and beverages. Geographically, Ecuador saw the most significant spike, accounting for 207 rejected batches, followed by Saudi Arabia (43 batches) and Australia (42 batches).
In May, the primary driver behind these border rejections was sodium metabisulfite, with 202 cases failing to meet China's national food safety standards. This represents a staggering jump from just 12 cases detected in April, signaling a sudden, widespread issue with sulfur dioxide–based food additives in imported foods—specifically frozen shrimp originating from Ecuador, Saudi Arabia, India, and Canada.
Sodium metabisulfite is a legally permitted additive in China, categorized under sulfur dioxide and sulfite-based preservatives. When dissolved in water, it releases sulfur dioxide, which acts as a powerful agent for color protection, bleaching, antimicrobial preservation, and anti-oxidation. It is widely used in processed fruits, vegetables, alcoholic beverages, and aquatic products.
⚠️Compliance Note: Sodium metabisulfite itself is not a banned substance. Rejections occur solely when its usage exceeds the maximum allowable thresholds or falls outside permitted food categories.
Preventing "Black Spot" (Enzymatic Browning): Shrimp shells and heads are naturally rich in polyphenol oxidase. Post-harvest, enzymatic reactions accelerate rapidly. Even under strict cold-chain conditions, oxidation eventually triggers melanin formation, causing unappealing blackening. Sodium metabisulfite inhibits these enzymes, preserving the shrimp's bright, fresh appearance and market value.
Preserving Freshness Over Long Transports: Major exporting nations like Ecuador and India rely heavily on long-distance ocean freight. The sulfur dioxide released by sodium metabisulfite disrupts microbial metabolism, inhibiting cold-tolerant and spoilage bacteria. This slows down protein degradation and prevents spoilage during weeks of transit.
While highly effective, excessive sulfite intake can irritate the respiratory tract, potentially triggering symptoms like chest tightness or coughing in asthmatic or sulfite-sensitive individuals. In the general population, extreme overexposure can cause gastrointestinal discomfort, including nausea and bloating.
To protect consumers, China enforces strict limits under GB 2760 National Food Safety Standard for the Use of Food Additives. The maximum allowable level for sodium metabisulfite (measured as sulfur dioxide residue) in frozen aquatic products like shrimp and crab is ≤ 0.1 g/kg. Any shipment exceeding this threshold is deemed non-compliant and denied market entry.
Seasonal Supply Peaks: May marks the peak harvest season for white shrimp in South America. The resulting surge in output and concentrated market supply naturally increases exporters' reliance on preservatives to handle massive volumes.
Rising Temperatures & Cold-Chain Stress: As the Northern Hemisphere warms up, maintaining cold-chain stability becomes increasingly challenging. Post-harvest shrimp become highly prone to rapid spoilage and blackening, prompting some overseas producers to over-apply sodium metabisulfite or distribute it unevenly, leading to localized violations.
Concentrated Shipments & Inspection Volumes: Driven by high procurement demand from China's foodservice and retail sectors, import arrivals surged in May. A larger testing pool naturally yields a higher number of non-compliant cases. Furthermore, a persistent lack of familiarity with China's specific regulatory limits among newer overseas producers continues to drive up violation rates.
ZMUni Insights
Many global food exporters face devastating border rejections simply due to a lack of preliminary compliance screening or a misunderstanding of China's shifting regulatory landscape. To prevent irreversible financial losses, enterprises are strongly encouraged to conduct comprehensive, proactive compliance assessments prior to shipment.
