Horse mackerel frozen

When sourcing frozen Horse Mackerel (Trachurus japonicus or Trachurus trachurus), you must prioritize freshness indices and processing methods. Look for fish with clear, bulging eyes and intact skin without yellowing (which indicates fat oxidation). The Glazing percentage is critical; a standard 5-10% protective water glaze is ideal to prevent freezer burn, but ensure you are paying for the net weight, not the gross weight including ice.

B2B buyers should specify IQF (Individually Quick Frozen) for retail-ready packs or BQF (Block Quick Frozen) for processing plants. Land-frozen products are common, but Sea-frozen (frozen on board) is the gold standard as it locks in freshness within hours of catch. Ensure the core temperature is maintained at -18°C or lower throughout the cold chain to prevent protein denaturation.

Suppliers must provide HACCP (Hazard Analysis and Critical Control Points) certification and ISO 22000 for food safety. For entry into the EU, the plant must be EU-approved, and for the US, FDA registration is required. Additionally, a Health Certificate, Certificate of Origin, and Catch Certificate (to prove the fish is not from IUU fishing) are non-negotiable documents for customs clearance.

Horse Mackerel is typically graded by weight (e.g., 100-150g, 150-200g, 200-300g) or by pieces per KG. Uniform sizing commands a premium but is essential for automated processing lines. Standard packaging is a 10kg or 20kg master carton; ensure the cartons are wax-coated or high-grammage to withstand high humidity in cold storage environments.

Always use Reefer Containers (Refrigerated Containers) equipped with Data Loggers to monitor temperature fluctuations in real-time. Set the contract to specify that any temperature deviation above -15°C for more than 4 hours constitutes a breach of quality terms. Conduct a Pre-shipment Inspection (PSI) by a third party like SGS to verify the TVB-N (Total Volatile Basic Nitrogen) levels, which measure spoilage.

Focus on long-term volume commitments rather than one-off spot buys to secure stable pricing in a volatile market. Request a breakdown of the Net Weight vs. Gross Weight to avoid paying for excess ice. If you are a new buyer, suggest a sample order of one pallet to verify the 'drip loss' after thawing before committing to a full container load (FCL).

Utilize Secured Payment services provided by professional platforms to ensure funds are only released upon proof of the Bill of Lading (B/L) and required health documents. For large orders, a Letter of Credit (L/C) at sight is the safest instrument, as it conditions payment on the presentation of compliant shipping and inspection documents.

Be aware of Anti-Dumping duties or specific biosecurity quotas that may apply to seafood imports in your country. When shipping to landlocked regions or distant ports, ensure the Demurrage and Detention (D&D) terms are negotiated for at least 14 free days, as frozen goods often face longer customs inspection times due to sanitary and phytosanitary (SPS) checks.
