Bulk Seafrozen Horse Mackerel

Under FOB (Free On Board), the buyer pays for sea freight, insurance, destination port charges, customs clearance, and inland transport. Under CFR (Cost and Freight), the seller pays freight to the destination port, but the buyer still pays insurance, port handling, and customs fees. Hidden costs buyers often miss: (1) Reefer monitoring fees – who pays for temperature data logger installation and report retrieval? (2) Port storage – if customs clearance is delayed, demurrage charges apply. (3) Glazing verification – buyers may need to pay for third‑party net weight inspection. Always get a written cost breakdown from the supplier before signing.

Immediately upon power loss: (1) Do not open the cold store doors – trapped cold air will retain safe temperatures for 4‑6 hours if doors remain sealed. (2) Move the most valuable cartons (e.g., AAA grade) to an alternative freezer if available. (3) After 4 hours without power, cover the pallets with insulated blankets (aluminium‑faced bubble wrap) to slow temperature rise. (4) Measure core temperature of sample cartons every 2 hours. If the core temperature remains below -12°C for the entire 8 hours, the fish is likely salvageable for cooking applications (not sashimi). If the temperature rises above -8°C, the fish must be processed immediately (canned, cooked, or frozen again only if cooked) or sold at a discount to fishmeal plants. Always maintain an emergency generator or have a backup cold storage agreement with a nearby facility.

Mixing light catch and trawl catch in the same container is strongly discouraged. Light catch fish have intact scales, bright eyes, and firm bellies; trawl fish typically have scale loss, bruising, and softer texture. When mixed, a buyer cannot distinguish which cartons belong to which catching method, and any quality claim becomes impossible to enforce. If a buyer accepts mixing due to supply constraints, the contract must specify: (1) each catching method packed in separately marked cartons (e.g., "Light Catch" vs. "Trawl" printed on carton), (2) separate packing lists for each type, and (3) a price differentiation – light catch should be invoiced at a higher price. Without these controls, the buyer will likely receive mostly trawl fish but pay an average price, suffering a net quality loss.
