U.S. imports of animal guts, bladders, and stomachs (excluding fish), whole or in pieces (HS 050400) totaled $5.4M in April 2026, traded with 19 countries.
The US tariff schedule subdivides animal guts, bladders, and stomachs into seven 10-digit lines under 050400, distinguishing hog casings (0504000020), other sausage casings (0504000040), frozen beef tripe (0504000050), frozen beef intestines (0504000070), frozen pork intestines (0504000080), and residual categories — reflecting the dual commercial role of these products as natural sausage casings and as edible offal. Canada leads imports, followed by Spain and Portugal, which are major European processors of natural casings for the charcuterie and sausage industries. USDA FSIS governs these products as meat byproducts, requiring entry from approved foreign establishments and port-of-entry reinspection. The sausage-casing versus non-casing distinction is commercially and tariff-significant, as different lines apply depending on intended use.

The US schedule separates guts and intestines destined for sausage casing use (0504000020 for hog; 0504000040 for other species) from those imported for other purposes such as direct consumption as tripe or offal (e.g., 0504000050 for frozen beef tripe, 0504000070 for frozen beef intestines, 0504000080 for frozen pork intestines). The importer's declared intended use, supported by commercial documentation, determines which line applies — and misclassification between casing and non-casing lines is a known audit risk.
All animal guts, bladders, and stomachs covered by 050400 are meat byproducts subject to USDA FSIS jurisdiction. Shipments must originate from an FSIS-eligible foreign country and an approved foreign establishment, be accompanied by a foreign government inspection certificate, and undergo FSIS reinspection at a designated US port of entry. Importers should verify that the foreign establishment's FSIS approval covers the specific product type being imported. Consult a licensed customs broker or FSIS for current admissibility requirements.
