Last updated: April 2026 dataUSDA FSIS jurisdiction applies to imported animal guts, bladders, and stomachs intended for food use, requiring that shipments originate from FSIS-approved foreign establishments and undergo reinspection at the US port of entry. The US tariff schedule subdivides this heading into seven 10-digit lines distinguishing hog casings (0504000020), other sausage casings (0504000040), frozen beef tripe (0504000050), frozen beef intestines (0504000070), frozen pork intestines (0504000080), and residual categories—making precise end-use and species declaration essential. Canada leads US supply, with Spain and Portugal also prominent sources, reflecting Europe's established natural casing processing industry.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Hog casings for sausage use must originate from an FSIS-approved foreign establishment. Required documentation typically includes a foreign inspection certificate, a health certificate from the exporting country's competent authority, and accurate commercial invoices specifying species, intended use, and processing state. FSIS reinspection occurs at the US port of entry.
The US schedule separates frozen beef tripe (0504000050) from frozen beef intestines (0504000070) as distinct 10-digit lines, even though both are bovine offal. Tripe refers specifically to stomach lining, while intestines are classified separately. Misidentification between these lines can result in classification errors and potential penalties, so species and anatomical part must be clearly stated on commercial documents.
