Live, fresh or chilled

This code covers live, fresh, or chilled clams, cockles, and ark shells. Use this code when importing these molluscs—typically duty-free for standard trade partners or eligible FTA programs—as part of broader fish and aquatic invertebrate imports detailed in Chapter 3.

Detailed information for HTS Code 0307.71.00

This section of the Harmonized Tariff Schedule covers live, fresh, or chilled molluscs, specifically clams, cockles, and ark shells. The 0307.71.00 code identifies these molluscs in their live, fresh, or chilled state, and further breaks down into specific types of clams and other molluscs. Statistical suffixes are used to differentiate between Geoduck clams (0307.71.00.50), other clams (0307.71.00.70), and other types of molluscs within this group (0307.71.00.90), so be sure to select the appropriate suffix based on the specific type of mollusc being reported. Remember this section excludes mammals, fish not for human consumption, and certain processed products like caviar.

Special rates are not specified, but eligibility for FTA or preference programs could potentially offer reduced or zero duty rates. All imports under this code and its subdivisions are reported in kilograms (kg). Therefore, while the base rate is free for many importers, specific FTA eligibility would determine any further reductions in duty.
