Statistics on domestically grown catfish and trout, and U.S. imports and exports of fish and shellfish that may be products of aquaculture, such as salmon, shrimp, and oysters.

NOTE: Product lines reported in the aquaculture trade tables are based on ERS aggregations of 10-digit HTS (Harmonized Tariff Schedule) and Schedule B codes intended to encompass all of the product forms, types and varieties that are commonly associated with each particular aquaculture category. Updates to the Harmonized Tariff Schedule and to Schedule B are made routinely to account for new or discontinued products, product classifications, and definitions, and as a result, commodity aggregations must also be routinely reviewed. The following document contains the current HTS and Schedule B codes that ERS aggregates for imports and exports, respectively. ERS aquaculture trade codes.xls.

More information on current HTS codes is available on the U.S. International Trade Commission website, here. Schedule B codes for 2019 (from the U.S. Census Bureau) are available here.
