🦿 Prosthetic Limb Practice Models (Practice Feet for Rehabilitation & Training)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Truly Understand "Practice Prosthetic Feet"?
Prosthetic limb practice models are specialized medical or educational devices used for physical therapy, rehabilitation training, or demonstration purposes. In international trade, they are generally categorized based on their primary function: whether they serve as medical substitutes for human body parts or as educational/rehabilitation training models.
Key Distinction Points: - If the item is designed to replace or simulate a body part for medical implantation or direct substitution purposes (even for practice), it falls under Chapter 90 (Medical/Orthopedic Appliances). - If the item is strictly a training prop for sports/physical therapy without medical substitution intent, it may fall under Chapter 95 (Sports Equipment) or Chapter 90 (Educational Models).
⚠️ Critical Classification Logic:
- Medical/Rehabilitation Use: Prioritize 9021.39.00.00 ("Parts of artificial joints or other orthopedic appliances") or 9023.00.00.00 ("Instruments, apparatus and models, designed for demonstrational purposes...").
- Sports/Training Use: If used purely for limb movement simulation in sports contexts, consider 9506.99.60.80 ("Other sports goods").
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Primary Use | Key Characteristics |
|---|---|---|---|
| 9021.39.00.00 | Artificial Body Parts (Substitutes) Parts of artificial joints or other orthopedic appliances |
Medical practice, surgical simulation, direct limb substitution | ✅ Classified as "Artificial Body Part Substitute" ✅ Fits the "Other" category fallback principle for medical orthopedic devices |
| 9506.99.60.80 | Sports/Training Equipment Other sports goods, including training aids for limb movement |
Sports rehabilitation, physical therapy drills, simulation training | ✅ Classified as "Sports/Training Apparatus" ✅ For limb movement recovery or simulation |
| 9023.00.00.00 | Demonstration Models Instruments, apparatus, and models for demonstrational purposes |
Medical education, hospital training, clinical demonstrations | ✅ Classified as "Educational/Rehabilitation Model" ✅ Functionally identical to "demonstration models" |
🔍 Key Reminder:
- 9021.39.00.00 is the most accurate classification if the product is marketed as a "prosthetic limb substitute" for medical/surgical practice.
- 9506.99.60.80 applies if the product is explicitly labeled as a "sports training aid" for physical therapy or rehabilitation.
- 9023.00.00.00 is suitable if the product is a static or semi-static model used solely for teaching or demonstration in medical/educational settings.
💰 III. 2026 Latest Tariff Rate Breakdown (Including Additional Duties & Policy Add-ons)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: November 10, 2025 onwards (including subsequent imports)
🎯 1. 9021.39.00.00 — Artificial Body Part Substitutes (Prosthetic Practice Feet)
| Item | Content |
|---|---|
| Base Duty | 0% (ad valorem) |
| USITC Additional Duty | 0% (No 301 tariff applies to this specific orthopedic subheading in some contexts, but check latest footnote) |
| Section 301 / IEEPA Add-on | +10% (122-Clause Tariff applicable to China-origin products) |
| Total Tax Rate | 10.0% |
| Tax Calculation | CIF Value × 10% |
| De Minimis Exemption Eligibility | ❌ Not Eligible (High-value medical devices often excluded) |
| Legal Basis Path | IEEPA:9903.01.25 → USITC:9021.39.00.00 → FOOTNOTE:301 |
📌 Explanation:
- The 10% additional duty is levied under the 122-Clause Tariff (Section 301/IEEPA) targeting Chinese medical/orthopedic goods.
- Base duty is 0%, making this the most cost-effective classification for prosthetic limbs.
- Total cost impact: 10% is significantly lower than sports equipment classifications.
🎯 2. 9506.99.60.80 — Sports/Training Equipment (Rehabilitation Practice Feet)
| Item | Content |
|---|---|
| Base Duty | 4.0% |
| USITC Additional Duty | +7.5% (Section 301) |
| Section 301 / IEEPA Add-on | +10% (122-Clause Tariff) |
| Steel/Aluminum/Copper Products Add-on | +50% (If the practice foot contains significant metal components classified under these materials) |
| Total Tax Rate | 21.5% (Without metal add-on) 71.5% (If metal add-on applies) |
| Tax Calculation | CIF Value × 21.5% (or 71.5%) |
| De Minimis Exemption Eligibility | ❌ Not Eligible |
| Legal Basis Path | IEEPA:9903.01.25 → USITC:9506.99.60.80 → FOOTNOTE:301 |
📌 Warning:
- This classification is significantly more expensive due to the base 4% duty plus multiple add-ons.
- If the product contains metal parts (e.g., aluminum joints, steel pins), the 50% metal surcharge may apply, leading to a total tax of 71.5%.
- Avoid this classification unless the product is explicitly marketed as "Sports Equipment" and not "Medical/Orthopedic."
🎯 3. 9023.00.00.00 — Demonstration Models (Educational/Rehabilitation Practice Feet)
| Item | Content |
|---|---|
| Base Duty | 0% |
| USITC Additional Duty | +7.5% (Section 301) |
| Section 301 / IEEPA Add-on | +10% (122-Clause Tariff) |
| Total Tax Rate | 17.5% |

| De Minimis Exemption Eligibility | ❌ Not Eligible |
| Legal Basis Path | IEEPA:9903.01.25 → USITC:9023.00.00.00 → FOOTNOTE:301 |
📌 Note:
- This is a mid-tier classification. While base duty is 0%, the 7.5% + 10% add-ons make it more expensive than 9021.39.00.00.
- Suitable for static models used in classrooms or hospitals for teaching, but not ideal for dynamic prosthetic practice.

✅ 3. Special Cases Handling
| Scenario | Handling Advice |
|---|---|
| Dynamic vs. Static | If the practice foot moves like a real limb, prefer 9021.39.00.00 (medical appliance). If static, consider 9023.00.00.00. |
| Material Composition | If the product contains >10% metal by value, 9506.99.60.80 may trigger the 50% steel/aluminum surcharge. Consult a customs broker. |
| OEM Customization | Provide client design documents to justify the "medical/rehabilitation" intent, supporting 9021.39.00.00. |
| Dual-Use Products | If marketed as both "Sports" and "Medical," choose the lower-tariff classification (9021.39.00.00) and provide supporting medical documentation. |

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
