Detailed information for HTS Code 0306.19.01

This section of the Harmonized Tariff Schedule covers live, fresh, chilled, frozen, dried, salted, or smoked crustaceans, and crustaceans cooked by steaming or boiling. The 0306.19.01 code specifically refers to frozen crustaceans, categorized as ‘other’ within the larger frozen crustacean group. Further breakdowns exist for freshwater crawfish (0306.19.01.10), Antarctic krill (0306.19.01.30), and all other frozen crustaceans (0306.19.01.61), so choose the most specific statistical suffix that accurately describes the product being classified.
