Skinned, whether or not divided into pieces, and frozen into blocks each weighing over 4.5 kg, imported to be minced, ground or cut into pieces of uniform weights and dimensions

This code covers frozen, skinned flat fish fillets (like Greenland turbot, sole, flounder, halibut, and turbot) weighing over 4.5kg, specifically imported for processing into smaller portions. Use this code when importing these large frozen fish blocks, as the duty is generally free for standard trade partners, falling within Chapter 3 covering fish and other aquatic life.

Detailed information for HTS Code 0304.83.10

This section of the Harmonized Tariff Schedule covers fish fillets and other fish meat, whether fresh, chilled, or frozen. Specifically, code 0304.83.10 applies to frozen flat fish fillets that are skinned, weigh over 4.5 kg per block, and are imported for further processing into minced, ground, or uniformly sized pieces. Several subdivisions exist to differentiate the type of flat fish, including Greenland turbot, sole, flounder, halibut, turbot, and other varieties, so be sure to select the appropriate statistical suffix based on the specific fish being imported. These subdivisions provide a more detailed classification within the broader category of processed flat fish fillets.
