Hard Protein Casing

🛡️ Hard Protein Casing (Sausage Casings)

🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Hard Protein Casings"?

Hard Protein Casings, also known as Edible Protein Casings or Collagen Casings (depending on raw material), are edible containers used to encase ground meat mixtures for sausages (frankfurters, salamis, bologna, etc.). They are typically derived from bovine hide (collagen), fish, or other animal proteins.

In international trade, they are strictly categorized based on their material composition and processing state:

Natural Protein Casings: Made from cleaned animal intestines (mostly sheep, hog, or beef).
Collagen/Protein Casings: Made from processed protein (collagen from hide) or other edible proteins.

⚠️ Key Distinction:
- If the casing is edible and used for food packaging → Chapter 02 or 05 (depending on raw material).
- If the casing is inedible (e.g., cellulose, plastic, metal) → Chapter 39, 48, or 73.
- Most "Hard Protein Casings" in commercial trade are Edible Collagen/Protein Casings.

📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)

🔍 Critical Reminder:
- Edible Collagen/Protein Casings are most commonly classified under 0511.99.90 (as "other animal products") or sometimes 0504.00.90 if derived from processed guts.
- Natural Intestine Casings fall under 0504.00.90.
- Inedible Casings (plastic/cellulose) fall under Chapter 39.
- Never classify edible protein casings under Chapter 39 (plastics) unless they are explicitly inedible.
