🥩 Hard Protein Sausage Casings (Collagen/Protein-Based)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Know "Hard Protein Casings"?
Hard protein sausage casings, typically made from collagen (derived from animal hides/bones) or concentrated protein isolates, are rigid or semi-rigid edible or non-edible shells used to encase sausage meat. In international trade, their classification depends heavily on whether they are considered raw materials for food production or finished food components.
Collagen/Protein Extracts: The raw material stage, often processed into powder or gelatin-like substances before casing formation.
Pre-formed Casings: Finished cylindrical tubes ready for stuffing machines.
⚠️ Key Distinction:
- If classified as protein derivatives/glues (industrial or non-food primary use) → 3501/3504
- If classified as finished food products (sausage casings ready for stuffing) → 1601 (less precise but context-dependent) or 3504 (as protein derivatives).
- Note: The provided data highlights a critical ambiguity between Chapter 35 (Protein derivatives) and Chapter 16 (Meat products).
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Tax Status |
|---|---|---|---|
3501.90.20.00 |
Casein glues (Other) | Casein-based casings used primarily as adhesives or industrial binders | ✅ 0.0% |
3501.90.60.00 |
Other casein derivatives (Other) | Non-glue casein derivatives, possibly some rigid protein shells not fitting glue category | ✅ 0.0% |
3504.00 |
Peptones; other protein substances and derivatives thereof | Most accurate for Collagen/Protein Casings (Applicable to hard protein sausage casings made from collagen/protein) | ⚠️ Error (Failed to retrieve) |
1601.00 |
Sausages and similar products of meat, offal or blood | Contextual Use: If the casing is considered part of a finished sausage product in specific contexts (though less precise for raw casings) | ⚠️ Error (Failed to retrieve) |
🔍 Important Reminder:
- Chapter 35 (HS 3504.00) is generally the most accurate for collagen casings because they are processed protein derivatives.
- Chapter 16 (HS 1601.00) is risky for empty casings unless they are pre-stuffed with meat. Empty casings are usually not classified as "sausages."
- Casein-specific HS Codes (3501) apply only if the casing is casein-based (less common for modern "hard" protein casings, which are mostly collagen).

- The system failed to retrieve tax data, which implies:
1. High Risk of Misclassification: The tariff structure may have changed or requires manual review.
2. Potential for High Duties: If misclassified, hidden duties (e.g., Section 301 tariffs) could apply.
3. Action Required: You must verify the exact rate with a customs broker or via the USITC Tariff Database for 3504.00.00.00.
🎯 3. 1601.00 —— Sausages & Similar Meat Products
| Item | Content |
|---|---|

📌 Critical Warning:
- Using 1601.00 for empty casings is highly discouraged and likely incorrect.
- Empty casings are not "sausages." Misclassification can lead to customs penalties, delays, or confiscation.
- If the data is missing, it may indicate that this HS code is not directly applicable or requires specific context (e.g., stuffed casings).
🛠️ IV. Customs Clearance Practical Advice (实战避坑指南)
✅ 1. Required Documentation Checklist (All are Mandatory)
| Document | Must Provide | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must specify: Material (Collagen/Casein/Protein), Edible/Non-edible, Diameter, Length, Packaging |
| ✅ Ingredient List | ✔️ | Critical for Chapter 35 vs. Chapter 16 classification |
| ✅ Product Photos | ✔️ | Clear images of the casing, label, and packaging |
| ✅ Certificate of Origin (CO) | ✔️ | To determine eligibility for preferential tariffs (if any) |
| ✅ Commercial Invoice | ✔️ | Must clearly state "Hard Protein Sausage Casings, Collagen-Based, Empty" |
| ✅ Packing List | ✔️ | Detail net/gross weight, dimensions |
✅ 2. Declaration Tips (Key Mantra)
🔥 "Material is Key, Empty is Not Meat, Chapter 35 is Safe!"
| Scenario | Correct Declaration | Wrong Approach |
|---|---|---|
| Empty Collagen Casings | 3504.00 (Peptones/Protein Derivatives) |
Misclassified as 1601.00 (Sausages) → High Risk |
| Casein-Based Casings | 3501.90.20.00 or 3501.90.60.00 |
Misclassified as 3504.00 → Possible Tax Discrepancy |
| Pre-stuffed Sausages | 1601.00 (if actually meat-filled) |
Declare as "Empty Casings" → Fraud Risk |
📌 Note:
- Never declare empty casings as "Sausages" (1601).
- Collagen casings are protein derivatives, not meat products.
- Casein casings are casein derivatives, which may have 0% tax.
✅ 3. Special Case Handling
| Situation | Handling Advice |
|---|---|
| Collagen Casings | Use HS 3504.00. Manually verify the tax rate due to retrieval error. Assume potential duties until confirmed. |
| Casein Casings | Use HS 3501.90.20.00 or 3501.90.60.00. 0% Tax is reliable. |
| Mixed Materials | Declare the primary material (e.g., "Collagen-based with protein coating"). |
| Edible vs. Non-Edible | Edible casings still fall under 3504 if empty. Non-edible (industrial) may also fall under 3504 or 3501. |
🌍 V. Global Market Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff | Certification | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 3504.00 |
Unknown/Error | FDA Registration | High Risk: Verify tax manually. |
| 🇺🇸 USA | 3501.90 |
0% | FDA Registration | Low Risk: If casein-based. |
| 🇨🇳 China | 3504.00 |
~5-10% | CCC (if applicable) | Standard protein derivative rate. |
| 🇪🇺 EU | 3504.00 |
0% (if GSP) | CE/FDA | Often duty-free for protein derivatives. |
| 🇯🇵 Japan | 3504.00 |
5-10% | FSC | Standard rate. |
📌 Conclusion:
- USA: Collagen casings (3504) have unclear tax data → High Risk.
- USA: Casein casings (3501) have 0% tax → Low Risk.
- Recommendation: Confirm material type. If collagen, prepare for potential duties. If casein, enjoy 0%.
📌 VI. Common Errors & Pitfalls (Lessons Learned)
❌ Mistake 1: Declaring empty collagen casings as 1601.00 (Sausages)
👉 Consequence: Customs rejection, penalties, or high duties due to misclassification.
❌ Mistake 2: Ignoring the "Failed to Retrieve" error for 3504.00
👉 Consequence: Unexpected tax bills or delays upon arrival.
❌ Mistake 3: Using "Glue" as the description for edible casings
👉 Consequence: Customs may suspect industrial misuse or fraud, leading to inspection.
❌ Mistake 4: Not specifying "Edible" or "Non-Edible"
👉 Consequence: Ambiguity leads to additional documentation requests and delays.
✅ Correct Practice:
"Collagen Sausage Casings, Edible, Empty, Hard Texture, Diameter 22mm, Net Weight 50kg, HS Code 3504.00"
🎯 VII. Conclusion: Precision in Classification Saves Money!
🎯 Remember the Mantra:
🔹 "Empty Casings are NOT Sausages!"
🔹 "Collagen = 3504 (Verify Tax) / Casein = 3501 (0% Tax)"
🔹 "Never Guess the Tax for 3504.00 – Manual Check is Mandatory!"
📌 Pro Tip:
If your collagen casings are originating from Vietnam, Mexico, or Thailand, you may be eligible for tariff exemptions under USMCA or other FTAs.
Always request a Pre-Ruling (Advance Ruling) from US Customs for 3504.00 to confirm the exact duty rate.

About HS Code Classification
The Harmonized System (HS) is an internationally standardized nomenclature developed by the World Customs Organization (WCO) to classify traded products. Over 200 countries use the HS system as the basis for customs tariffs, trade statistics, and import/export regulations.
Each HS code follows a hierarchical structure:
- Chapter (2 digits) — Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) — More specific grouping within the chapter
- Subheading (6 digits) — Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) — Country-specific extensions for further classification, such as US HTSUS 10-digit codes
Correct HS code classification is essential for smooth customs clearance, accurate duty payment, and compliance with trade regulations. Misclassification can lead to customs delays, overpayment of duties, or penalties.
When importing from CN to US, the applicable tariff rates may include:
- Most-Favored-Nation (MFN) rate — The standard duty rate applied to WTO members
- General rate — Applied to countries without trade agreements
- Trade remedy duties — Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
