Analysis
HTS 0307.22.00 covers scallops and other molluscs of the family Pectinidae: frozen under heading 0307 (molluscs, whether in shell or not, live, fresh, chilled, frozen, dried, salted or in…).
Neighbouring lines carry rates from duty-free to 5%, so the exact line matters. The widest gap is with 0307.60.00 (snails, other than sea snails), at 5%: a product that belongs there but is entered here, or the reverse, changes the duty by 5 percentage points.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 86% of the 272 tariff lines in chapter 03. 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 311710 (Seafood Product Preparation and Packaging), an industry of 516 US establishments employing 29,132 people. That is the industry code a US manufacturer of the same product would normally use.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
