Frozen Haddock Fillets

Line 0304721000 covers skinned haddock fillets presented in frozen blocks weighing more than 4.5 kg, a format typically used as input for further processing into breaded or minced products. Line 0304725000 is the residual 'NESOI' (not elsewhere specified or included) line covering all other frozen haddock fillets, including individual quick-frozen (IQF) retail-ready portions. Correct classification depends on both the skinning status and the block weight at the time of importation.

Sustainability certifications such as MSC (Marine Stewardship Council) are voluntary and do not affect HTS classification or customs entry requirements. However, buyers and retailers increasingly require chain-of-custody documentation alongside commercial invoices. Separately, the US Seafood Import Monitoring Program (SIMP) requires harvest event data — including vessel, flag state, and fishing area — for certain species; importers should verify whether haddock is currently on the SIMP species list and maintain the required documentation accordingly.
