🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy for Medical & Fashion Imports
📌 I. Product Definition & Classification: What Does "Arm" Mean in Trade?
In international trade, the term "Arm" (手臂) is ambiguous and leads to massive classification errors. It generally falls into two completely different categories depending on the material and purpose:
- Medical Artificial Parts: Prosthetic limbs, artificial joints, or medical braces for the arm/shoulder.
- Fashion Apparel (Fur Products): Mink fur coats, jackets, or accessories featuring arm sleeves/cuffs.
⚠️ Critical Distinction:
- If the product is a prosthetic limb, artificial joint, or orthopedic brace → It is a Medical Device (Chapter 90).
- If the product is a garment made of mink fur (e.g., a coat with sleeves) → It is Fur Apparel (Chapter 43).
- You cannot mix these. A fur sleeve on a coat is not an artificial arm.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority)
Based on the provided data, here are the two distinct paths for products related to "arms" (either anatomical/medical or apparel):
| HS Code | Product Description | Application Scenario | Category |
|---|---|---|---|
9021.31.00.00 |
Artificial joints and parts and accessories thereof | Artificial shoulder/elbow joints, prosthetic arm connectors, hip/knee joints (often grouped here) | Medical Device |
9021.39.00.00 |
Other artificial parts of the body | Other prosthetic limbs (including arms), splints, surgical belts, trusses for arm support | Medical Device |
4303.10.00.30 |
Articles of apparel and clothing accessories Of mink | Mink fur coats, jackets, vests (including sleeves as part of the garment) | Fashion/Fur |
4303.10.00.60 |
Articles of apparel and clothing accessories Other | Other fur garments/accessories (not mink), or other fur apparel items | Fashion/Fur |
🔍 Key Note:
-9021.31.00.00is for artificial joints. If you are importing artificial elbow or shoulder joints, this is likely the code.
-9021.39.00.00is for other artificial parts. If you are importing a full prosthetic arm (not just a joint), this is the correct code.
-4303.10.00.30and4303.10.00.60are for fur garments. If you are importing a mink coat (which has arms/sleeves), it falls here. It is NOT classified as an "artificial body part."

🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Required Documentation List (Must-Have)
| Document | Mandatory? | Description |
|---|---|---|
| ✅ Product Specification | ✔️ | Medical: Diagrams, materials (silicone, titanium, etc.), intended use. Fur: Type of fur (mink), country of origin of fur, tanning method. |
| ✅ Product Photos | ✔️ | Clear images showing the product as shipped. For medical: show joints/connectors. For fur: show lining, zipper, fur texture. |
| ✅ Commercial Invoice | ✔️ | Must clearly state "Artificial Joint" OR "Mink Fur Coat". Do NOT write "Arm Parts" without clarification. |
| ✅ Certificate of Origin | ✔️ | Critical for fur to prove origin (mink fur has strict origin rules). |
| ✅ FDA Documentation | ✔️ | For Medical Only: FDA Establishment Registration, Listing Number, 510(k) clearance if applicable. |
| ✅ Fur Labeling | ✔️ | For Fur Only: Must comply with FTC Fur Products Labeling Act (origin, country of tanning). |
✅ 2. Declaration Tips (Key Mnemonic)
🔥 "Med Free, Fur High; Be Precise or Pay Twice!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Artificial Elbow Joint | 9021.31.00.00 - "Artificial Joint" |
"Arm Part" → Risk of misclassification → 29% tax! |
| Prosthetic Arm (Full) | 9021.39.00.00 - "Artificial Limb" |
"Clothing Accessory" → Risk of 29% tax! |
| Mink Coat | 4303.10.00.30 - "Mink Fur Apparel" |
"Medical Brace" → Fraud Risk + High Tax |
| Fur Mitten (Single) | 4303.10.00.60 (or 30 if mink) |
"Orthopedic Appliance" → Wrong Code |
📌 Crucial Warning:
- Never declare a fur coat as a "medical brace" to avoid tax. Customs can easily detect fur vs. medical materials.
- Never declare a prosthetic limb as "apparel." It is a medical device.
✅ 3. Special Cases
| Case | Handling Advice |
|---|---|
| OEM Prosthetic Arms | Provide FDA approval docs + technical drawings. Ensure "Made in China" is clear. |
| Mink Fur Sleeves (Detachable) | If sold separately as accessories, still 4303.10.00.30. If attached to coat, declared as coat. |
| Hybrid Products (e.g., Fur-lined Medical Braces) | Complex! Usually classified as medical device if primarily for medical use, but must prove "primary purpose." If fur is main feature, may fall under apparel. Seek pre-ruling. |
| Human Anatomical Models (for education) | Not covered in data. Likely 9023.00 (Instruments/Apparatus). Do not use 9021. |

👉 Consequence: Customs audit → 29% tax + 200% penalty + seizure.
❌ Error 2: Declaring a Prosthetic Arm as "Apparel" or "Accessories".
👉 Consequence: Incorrect classification → 29% tax instead of 0%.
❌ Error 3: Missing FDA Documentation for artificial joints.
👉 Consequence: Detention at US port → Delayed delivery, storage fees, potential return.
❌ Error 4: Using vague description "Arm Parts" in invoice.
👉 Consequence: Customs officer guesses → Likely classifies as higher-tariff category (e.g., machinery parts or apparel) → Unnecessary tax.
✅ Correct Practice:
"Artificial Elbow Joint, Titanium Alloy, FDA Cleared, Model XYZ, Made in China"
"Mink Fur Coat, Length 40 inches, Lined, Model ABC, Made in China"
🎯 VII. Conclusion: Professional Classification Saves Money!
🎯 Remember the Mnemonic:
🔹 "Medical Arms: 0% Tax. Fur Arms: 29% Tax. Be Specific!"
🔹 "HS Code Determines Cost. 29 Points Difference = Big Profit Loss!"
📌 Pro Tip:
- If you are importing medical artificial arms/joints, ensure you have FDA registration and clear technical specs to prove it's a medical device, not a "fashion accessory" or "toy."
- If you are importing fur apparel, budget for the 29% total tariff. Consider pricing strategies or origin shifting if possible.

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
