why choose our products
Frozen Pacific mackerel (Scomber japonicus) has moved from a bulk commodity to a strategically important item in the global frozen seafood trade. For exporters and importers alike, understanding its product formats, shifting demand centers, and cold-chain requirements is essential to remaining competitive.
Product Formats and Specifications
Pacific mackerel is traded predominantly as whole round frozen fish. Two processing methods dominate: block quick frozen (BQF), where fish are frozen together in a block, and individually quick frozen (IQF), where each fish is frozen separately. BQF remains the most common format for bulk export because it maximizes container utilization, while IQF commands interest in retail and foodservice channels that require piece-level separation. Size grading is a central commercial variable. Common export grades include 100–200 g, 200–300 g, and larger 400–500 g or 500 g+ specifications, allowing buyers to match product to canning, repacking, or direct retail use. Carton configurations typically range from 8 kg to 20 kg, with 10 kg and 15 kg formats widely used in Asian and African trade. The principal HS classification for frozen Pacific mackerel is 030354, with national tariff schedules sometimes extending the code to eight or ten digits.
Trade Flows and Demand Centers
Global frozen mackerel trade reached 1.24 million metric tons in 2024, with China and Norway as the leading suppliers. The geography of demand, however, is shifting. West Africa-particularly Côte d'Ivoire and Nigeria-remains the largest destination region for frozen mackerel by volume, reflecting strong price-sensitive demand. In Asia, import volumes have proven resilient even as prices climbed. Asia-Pacific frozen mackerel imports rose 8.87% year-on-year in 2025, with Vietnam as the largest market, China second, and Thailand, Indonesia, and Japan following. The most striking recent development has been Russia's emergence as a major growth market. Russia imported 70,000 tons of mackerel in 2025, up 2% in volume and 14% in value, with China's Pacific mackerel shipments to Russia surging 57% to 20,000 tons. China's overall frozen mackerel exports reached 206,257 tons in the first half of 2025 alone, a 34% year-on-year increase, positioning the country as the dominant volume supplier in the Pacific mackerel segment.
Price Dynamics and the Atlantic–Pacific Substitution Effect
Price formation in the mackerel trade has been reshaped by supply constraints in the Atlantic fishery. Norwegian Atlantic mackerel prices rose sharply in 2025 and 2026 following significant harvest quota cuts, with whole frozen mackerel under 600 g passing NOK 30, NOK 40, and NOK 50 per kg during 2025. This price escalation has redirected trade flows: processors facing higher Atlantic mackerel costs have increasingly turned to Pacific mackerel as a cost-effective alternative. Export prices for Pacific mackerel have varied by origin and specification, with reports of USD 1.50–1.70 per kg for certain grades and higher levels for larger fish. The substitution dynamic is not merely a temporary arbitrage; it reflects a structural adjustment in which Pacific mackerel is gaining share in price-sensitive markets and in processed product formulations where Atlantic mackerel has become prohibitively expensive.
Cold Chain, Documentation, and Compliance
Frozen mackerel is a temperature-sensitive commodity, and cold-chain discipline is non-negotiable. Export containers should operate between −18°C and −25°C, with product core temperature reaching −18°C or lower before shipment. Glaze percentage, inner packaging format, and carton weight should be specified in the sales contract, as these variables directly affect net weight and product protection during transit. Documentation requirements vary by destination but typically include a commercial invoice, packing list, bill of lading, certificate of origin, and a health certificate issued by the competent authority of the exporting country. Some markets additionally require catch certificates or traceability documentation linking the shipment to a licensed vessel or processing facility. Regulatory enforcement has tightened in key import markets: in January 2026, Indonesian authorities seized nearly 100 tons of illegally imported frozen Pacific mackerel at Tanjung Priok Port after an importer exceeded its quota, underscoring the importance of verifying import licensing and quota compliance before shipment.
For exporters, the Pacific mackerel opportunity lies in reliability rather than novelty: consistent grading, verifiable cold-chain records, and accurate documentation are the qualities that convert one-time buyers into long-term accounts.
