๐ Raw Lamb Skin (Preserved, Untanned, for Laboratory Use)
๐ HS Code Classification & Customs Clearance Guide | 2026 Updated Tariff Analysis | Expert-Level Compliance Strategy
๐ One Product, Multiple HS Codes โ But Only One Is Correct!
๐ Critical Insight:
The same product โ raw lamb skin preserved for scientific research โ can be classified under four different HS codes, each with radically different tariffs.
Choosing the wrong one could result in overpaying 10โ20% in duties, customs delays, or even detention.
๐ฆ 1. HS Code Classification Breakdown (2026 Updated)
| HS Code | Product Description | Key Classification Logic | Tax Rate |
|---|---|---|---|
9705.22.00.00 |
Scientific research specimens: biological material (e.g., animal skin) preserved for study | Matches "scientific research" use + biological origin; treated as a research collection item despite not being endangered | 10.0% |
9705.29.00.00 |
Other works of art or scientific specimens: preserved animal skin for academic interest | Fits "preserved for scientific research" + biological specimen with educational/collectible value | 10.0% |
4103.90.20.00 |
Other raw hides and skins, not tanned or limed: sheep or lamb skin | Material is raw, untanned lamb skin โ core definition of raw hides; preservation status does not change physical classification | 20.8% |
4103.90.11.90 |
Other raw hides and skins, not tanned or limed: specifically lamb skin | Explicitly includes lamb skin as raw, unprocessed material; โpreservedโ โ โtannedโ | 17.5% |
โ Bottom Line:
-4103.90.20.00and4103.90.11.90are material-based classifications โ correct if the product is raw, untanned hide.
-9705.22.00.00and9705.29.00.00are purpose-based โ valid only if the item is clearly a scientific specimen or collectorโs item, not just raw hide.
๐ฐ 2. Detailed Tariff Breakdown (US Market | 2025โ2026)
๐ฏ 1. 9705.22.00.00 โ Scientific Research Specimens (Biological)
| Tax Component | Rate | Legal Basis |
|---|---|---|
| Basic Duty | 0.0% | General tariff rate |
| Additional Duty (Section 301) | 0.0% | Not subject to USITC 301 |
| Section 122 Tariff (IEEPA) | 10.0% | Under International Emergency Economic Powers Act (IEEPA) for goods from China |
| Total Effective Duty | 10.0% | CIF ร 10% |
๐ Why This Applies:
- The item is preserved for scientific research โ a key factor in 9705.22.00.00.
- Even though lamb skin is not endangered, the purpose-driven classification treats it as a scientific specimen under the "collection" logic of the subheading.
๐ฏ 2. 9705.29.00.00 โ Other Scientific Specimens (Animal Skin)
| Tax Component | Rate | Legal Basis |
|---|---|---|
| Basic Duty | 0.0% | General tariff rate |
| Additional Duty (Section 301) | 0.0% | Not covered by USITC 301 |
| Section 122 Tariff (IEEPA) | 10.0% | IEEPA applies to China-origin goods |
| Total Effective Duty | 10.0% | CIF ร 10% |
๐ Why This Applies:
- The product is preserved animal skin with scientific interest.
- "Preserved for scientific research" confirms its non-commercial, academic use, qualifying it as a specimen for collection or study.
๐ฏ 3. 4103.90.20.00 โ Raw Hides & Skins (Not Tanned), Other
| Tax Component | Rate | Legal Basis |
|---|---|---|
| Basic Duty | 3.3% | Standard rate for raw hides |
| Additional Duty (Section 301) | 7.5% | USITC 301 Tariff (China-origin goods) |
| Section 122 Tariff (IEEPA) | 10.0% | IEEPA applies to goods from China |
| Total Effective Duty | 20.8% | CIF ร 20.8% |
๐ Why This Applies:
- The material is raw, untanned lamb skin โ fits 4103.90.20.00 perfectly.
- Preservation (e.g., chemical fixation) does not change the physical state โ still raw hide, not tanned.
- High-risk for misclassification: If you claim itโs a โspecimen,โ but the material is clearly raw hide, customs may reclassify it to 4103.90.20.00 โ double the tax!
๐ฏ 4. 4103.90.11.90 โ Raw Hides & Skins (Not Tanned), Lamb Skin
| Tax Component | Rate | Legal Basis |

| Section 122 Tariff (IEEPA) | 10.0% | IEEPA applies to China-origin goods |
| Total Effective Duty | 17.5% | CIF ร 17.5% |
๐ Why This Applies:
- Explicitly covers lamb skin as raw, untanned hide.
- Most accurate for lamb-specific raw skin.
- Lower base duty than4103.90.20.00, but still subject to 7.5% + 10%.
๐ ๏ธ 3. Customs Clearance Best Practices (Pro Tips)
โ 1. Required Documentation (Must-Have)
| Document | Why Itโs Critical |
|---|---|
| โ Commercial Invoice | Must clearly state: "Raw Lamb Skin, Untanned, Preserved for Laboratory Use" |
| โ Product Specification Sheet | Include: origin, preservation method (e.g., formalin, ethanol), weight, size, intended use |
| โ Lab Use Certificate / Research Purpose Letter | From university, lab, or research institution โ proves scientific use |
| โ Third-Party Lab Test Report | Confirms no tanning agents, no chemical processing |
| โ Packing List | Shows no tanned material, no finished products |
| โ Certificate of Origin (CO) | If from China โ triggers IEEPA & Section 301 duties |

- If itโs clearly a scientific specimen with lab documentation โ9705.22.00.00or9705.29.00.00(10.0%)โ ๏ธ Critical Decision Rule:
- Material > Purpose in U.S. customs.
- If the physical state is raw hide, you must use 4103.90.11.90 or 4103.90.20.00, even if itโs for research.
๐ 6. Pro Tips for Cost Optimization
๐ Save 7.5% in Duty? Hereโs How: - Source from non-China countries (Vietnam, India, Thailand) โ avoid IEEPA & Section 301 - Apply for HTS Pre-Ruling (Advance Ruling) โ lock in the correct HS code before shipment - Use โPreserved for Scientific Researchโ as a secondary descriptor, not the primary classification
๐ฏ Summary: The 3-Step Rule for Success
- Check the Material: Is it raw, untanned lamb skin? โ Use 4103.90.11.90
- Check the Purpose: Is it a specimen in a lab collection? โ Use 9705.22.00.00 (only with proof)
- Check the Origin: Is it from China? โ Add 10% IEEPA + 7.5% Section 301 (if using 4103.90.11.90)
๐ฃ Final Advice:
๐น Donโt rely on โfor researchโ alone โ customs will look at material state first.
๐น Document everything: lab letters, preservation method, species ID.
๐น Apply for pre-ruling if shipping large volumes โ avoid costly disputes.

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) โ Broad category of goods (e.g., Chapter 84: Machinery and Mechanical Appliances)
- Heading (4 digits) โ More specific grouping within the chapter
- Subheading (6 digits) โ Internationally standardized breakdown, used by all WCO member countries
- National subdivisions (8-10 digits) โ 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 โ The standard duty rate applied to WTO members
- General rate โ Applied to countries without trade agreements
- Trade remedy duties โ Additional tariffs such as Section 301 (anti-dumping), Section 232 (national security), or countervailing duties
