Last updated: August 2026 dataFish heads, tails, and swim bladders (maws) preserved by smoking, drying, salting, or brining are consolidated under a single US tariff line (0305720000) and represent a commercially distinct trade stream driven largely by demand in Asian and Latin American culinary markets. Vietnam and China are the leading suppliers, with Mexico, Hong Kong, and Colombia also contributing. USDA FSIS admissibility requirements apply, and importers should note that fish maws — particularly dried swim bladders — can command significant value as a specialty ingredient, making accurate valuation and species documentation important at entry. Classification here requires that the product consists of these specific anatomical parts rather than fillets or whole fish.

Dried swim bladders of fish classify here under 0305.72 when they are in the form of the raw preserved anatomical part. However, if swim bladders have been further processed into extracts, powders, or preparations, they may shift to Chapter 16 or Chapter 21. The product's physical form and degree of processing at the time of import determine the correct heading.
Premium dried fish maws — particularly from large species — can carry very high per-kilogram values, making transaction value documentation critical. CBP may scrutinize declared values against market benchmarks. Importers should retain purchase invoices, species identification records, and any grading certificates to support the declared customs value and avoid valuation disputes at entry.
