HS Code for Artificial casing

Artificial casings, specifically those used as sausage skins, are classified under HS code 3917.10. This code is designated for artificial guts made from hardened protein or cellulosic materials. These materials are processed to mimic the properties of natural animal intestines while providing uniformity in diameter, strength, and hygiene for industrial food production. The classification depends strictly on the chemical composition of the casing; it must be derived from regenerated cellulose or protein substances like collagen. These products are essential in the meat processing industry for the manufacture of sausages, salamis, and other encased meat products. By placing them in Chapter 39, the Harmonized System recognizes them as products of the plastics and polymer industry, even though they are used exclusively in food applications.

Products Included

Common Misclassification

Artificial casings are often confused with HS code 0504, which covers natural animal guts, bladders, and stomachs. They may also be misclassified under 3917.21 through 3917.39 if the customs officer treats them as standard plastic tubing rather than the specialized food-grade casings defined in 3917.10.

FAQ

What is the HS code for Artificial casing?

The HS code for artificial casings made of hardened protein or cellulosic materials is 3917.10.

Are plastic casings made of polyamide included here?

No, casings made of synthetic plastics like polyamide (nylon) that are not hardened protein or cellulose are typically classified under other subheadings of 3917, such as 3917.32.
