U.S. imports of prepared or preserved molluscs (not elsewhere specified) (HS 160559) totaled $354K in July 2026, traded with 16 countries.
Importers of Prepared or Preserved Molluscs (Not Elsewhere Specified) paid $51K in duties in July 2026 — an effective duty rate of 14% on $354K in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataServing as the catch-all for prepared and preserved molluscs not covered by the more specific headings for oysters, mussels, scallops, clams, abalone, octopus, squid, or snails, this residual heading captures a diverse range of specialty shellfish products. Thailand and Vietnam lead US supply, with China also a significant source — and goods of Chinese origin may be subject to Section 301 tariffs. The schedule distinguishes composite products containing fish meat or prepared meals (1605590500) from straight mollusc preparations (1605590000 / 1605596000). Correct classification requires confirming that the specific mollusc species is not more precisely described under another heading in Chapter 16. FDA prior notice and HACCP compliance are required; consult a licensed customs broker to confirm the appropriate tariff line.

Chapter 16 contains dedicated headings for oysters, mussels, scallops, clams, cockles, arkshells, abalone, octopus, squid, cuttlefish, and snails. If the mollusc species is covered by one of those specific headings, it must be classified there rather than under the residual 160559 heading. Only species not described elsewhere — such as certain whelks, periwinkles, or lesser-traded bivalves — properly fall here.
Line 1605590500 applies when the preparation contains fish meat in addition to mollusc, or constitutes a prepared meal. This distinction affects not only classification but potentially the applicable duty rate. Importers of mixed seafood products or ready-to-eat preparations should have their product formulation reviewed to determine whether the fish-meat line or the straight mollusc line is correct.
