Collagen Sausage Casing for Pork Links from China
Edible collagen-based sausage casings specifically designed for encasing fresh pork sausage links, formed from hardened bovine collagen protein. These casings provide a natural-looking barrier that shrinks during cooking, classified under HTS 3917.10.60.00 as artificial guts of collagen for food processing. They meet the chapter's polymer classification by being protein-derived rather than synthetic plastic.

Import Tips
• Verify collagen source (e.g
• bovine) and provide certificates of edibility from FDA-approved suppliers to meet food import standards
• Ensure labeling distinguishes from cellulosic casings to avoid reclassification
• Check for attached fittings, as duty-free status under heading 3917 requires them for certain rates
