Last updated: April 2026 dataProcessed natural gut and related animal-membrane articles — excluding silkworm gut — serve highly specialized end uses including surgical sutures, musical instrument strings, and sporting goods such as tennis racket strings. The animal-origin nature of these materials means that USDA APHIS may require import permits or health certificates depending on the species and country of origin, and some articles may also be subject to FDA oversight if intended for medical use. Classification precision matters because gut used for sutures, strings, and industrial applications may be treated differently depending on the degree of processing and the declared end use.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
USDA APHIS may require import permits or veterinary health documentation for animal-derived membrane articles, depending on species and country of origin. If the article is intended for use as a medical device or surgical suture, FDA oversight also applies. Importers should confirm applicable permit requirements before shipment, as admissibility rules vary by end use and origin.
End use can be a significant classification factor. Gut strings for musical instruments and gut used in surgical sutures may be classified under different headings based on their processing state and intended application. Importers should declare the specific end use on entry documentation and consult a licensed customs broker to confirm the correct classification.
