🐑 Blue Wet-Lamb Skin Raw Material (Chemically Tanned, Unfinished)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
📌 I. Product Definition & Classification: Do You Really Understand "Blue Wet-Lamb Skin"?
"Blue wet-lamb skin" refers to raw lamb skins that have undergone chrome tanning (or other tanning processes) but have not yet undergone dyeing, finishing, or further leather processing. They are in an intermediate state between raw hides and finished leather. In international trade, they are classified as "Crude Hides and Skins" or "Leather" depending on the extent of processing, specifically falling under the leather chapter due to the tanning process.
Key Distinction:
- Raw Skins (Untanned): Must be salted or preserved without tanning agents → Classified in Chapter 41 (Section II).
- Blue Wet Skins (Tanned but Unfinished): Have been tanned (usually with chromium salts, hence the "blue" color indicating chrome tanning) but are not yet dyed, buffed, or coated → Classified in Chapter 41, specifically as Leather (Section XI, Chapter 41).
⚠️ Critical Classification Point:
- If the skin has been tanned (even if only "blue" stage) → It is Leather (HS Code starts with 4104 or 4105).
- If it is untanned, merely salted/dried → It is Raw Skin (HS Code starts with 4103 or 4102).
- "Blue" specifically implies chrome tanning, so it must be classified under the leather heading.

- If the skin is wet and packaged in brine/salt, it is still leather if tanned.

🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Required Documents Checklist (Missing Any = Delay/Return)
| Document | Must Provide | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must state: "Chrome Tanned," "Wet Blue," "Sheep/Lamb," "Unfinished." |
| ✅ Process Flow Diagram | ✔️ | Show steps: Raw → Soaking → Lime → Fleshing → Beamhouse → Chrome Tanning → Wet Blue. |
| ✅ Product Photos | ✔️ | Clear image of the interior (blue color), exterior, and packaging. |
| ✅ Third-Party Test Report | ✔️ | Chrome Content Test (must confirm tanning). Certifications: REACH, OEKO-TEX (if applicable). |
| ✅ Commercial Invoice | ✔️ | Use precise description: "Wet Blue Sheepskins, Chrome Tanned, Unfinished." Do NOT write "Raw Skins." |
| ✅ Packing List | ✔️ | Show net/gross weight. Note if packed in salt/brine. |
| ✅ Bill of Lading | ✔️ | Consignee details, vessel info. |
✅ 2. Declaration Tips (Key Mnemonic)
🔥 "Tanned is Leather, Raw is Skin; Blue Means Chrome, Don't Lie!"
| Scenario | Correct Declaration | Wrong Action |
|---|---|---|
| Chrome-tanned, unfinished | 4105.30.90.00 |
Misdeclare as "Raw Skin" (4106) → Penalty |
| Dyed/Finished Leather | 4105.30.00.00 (or other subhead) |
Misdeclare as "Unfinished" → Over/Under-pay |
| Raw, Salted Skins | 4106.22.00.00 |
Misdeclare as "Leather" → Unnecessary Tax |
| Sample for Testing | Same as full batch | Declare as "Sample" → Customs may still tax |
✅ 3. Special Situation Handling
| Situation | Handling Advice |
|---|---|
| Wet vs. Dry | Wet blue skins are heavier due to water. Declare Net Weight accurately. Customs may adjust duties based on dry weight if disputed. |
| Packaging in Salt | Salt is considered part of the product weight. Ensure invoice states "Net Weight" excluding packaging if possible. |
| Mixed Batches | If a shipment contains both lamb and goat skins, separate them. Goat skins have different HS codes (4104). Mixing causes delays. |
| Chrome Content | Must comply with REACH (if EU) or US EPA standards. Provide test reports for hexavalent chromium limits. |

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
