0307.72.00

Analysis

HTS 0307.72.00 covers clams, cockles and ark shells (families Arcidae, Arcticidae, Cardiidae, Donacidae, Hiatellidae, Mactridae, Mesodesmatidae, Myidae, Semelidae, Solecurtidae… under heading 0307 (molluscs, whether in shell or not, live, fresh, chilled, frozen, dried, salted or in…). US Customs collects import statistics for it under 4 ten-digit suffixes, reported in kilograms.

Within this group the rate runs from duty-free to 5%. Compared with 0307.60.00 (snails, other than sea snails), which pays 5%, a misclassification either way moves the duty by 5 percentage points.

The normal trade relations rate here is zero, shared by about 86% of the 272 tariff lines in chapter 03, a useful check when a neighbouring dutiable line is a candidate. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.

Census statistics map these goods to NAICS 114112 (Shellfish Fishing), an industry of 940 US establishments employing 1,604 people. That concordance is how imports of this line are compared with US output.

The ten-digit suffixes separate geoduck and stimsonʼs. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.
