Last updated: July 2026 dataGut-based articles — excluding silkworm gut — occupy a narrow but commercially distinct niche, with the US tariff schedule separating catgut articles by end use: surgical suture manufacturing (4206001300), racquet strings (4206001910), and other catgut articles (4206001930). Catgut destined for sterile surgical suture production is subject to FDA oversight as a medical device input, adding a regulatory layer beyond standard customs clearance. Goldbeater's skin, bladder, and tendon articles are grouped in the residual line 4206009000 and are rarely traded in significant volume.

Yes. Catgut classified under 4206001300 as an input for sterile surgical suture manufacturing is subject to FDA oversight as a medical device component. Importers should be prepared for FDA review at entry and should ensure that the foreign manufacturer meets applicable quality system requirements. Consulting a licensed customs broker or regulatory counsel familiar with medical device imports is advisable given the complexity of admissibility requirements.
Natural gut racquet strings made from catgut are classified under 4206001910 within Chapter 42. Synthetic racquet strings made from nylon, polyester, or other man-made fibers are classified in Chapter 56 or Chapter 39, depending on their material composition. The distinction is material-based, so the fiber content of the string must be confirmed before classification.
