🧎♂️ Height-Increasing Insoles (Height-Increasing Stands)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategies
📌 I. Product Definition & Classification: Do You Truly Understand "Height-Increasing Insoles"?
Height-increasing insoles, often referred to as "lifts" or "height boosters," are accessories inserted into footwear to artificially increase the wearer's stature. In international trade, their classification depends heavily on their material composition, physical form, and intended medical function. They are generally categorized into three main types:
- Standard Cosmetic/Comfort Insoles: Made from rubber, EVA, sponge, or other non-metal materials, primarily for height enhancement and comfort.
- Removable Heel/Palm Parts: General accessories for shoes, not specifically designated for other categories.
- Orthopedic/Medical Devices: Designed for correction, support, or rehabilitation, falling under medical apparatus accessories.
⚠️ Key Distinction Point:
- If it is a simple EVA/Rubber pad for cosmetic height increase → Classified under 6406.90.90.00 or 6406.10.90.40
- If it is explicitly marketed as an orthopedic correction device or part of a medical system → Classified under 9021.90.81.00
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Applicable Scenario | Medical/Orthopedic Function? |
|---|---|---|---|
6406.90.90.00 |
Other footwear parts and accessories (Insoles, heels, etc.), of rubber/EVA/sponge | General cosmetic height increase, daily wear, sports shoes | ❌ No |
6406.10.90.40 |
Removable insoles, heel pads, and similar articles, other than those specified elsewhere | General shoe accessories, unspecified material preference | ❌ No (General Accessory) |
9021.90.81.00 |
Parts and accessories of orthopedic appliances and splints | Medical correction, foot deformity support, therapeutic use | ✅ Yes (Medical Device) |
🔍 Key Reminder:
- All non-medical, cosmetic height-increasing insoles must be classified under Chapter 64 (Footwear).
- If the product has a therapeutic purpose (e.g., correcting flat feet while increasing height), it may qualify for Chapter 90 (Medical Apparatus), which can significantly impact duty rates and regulatory requirements.

| Item | Content |
|---|---|
| Base Tariff | 4.5% |
| USITC Additional Duty | 0.0% |
| IEEPA Additional Duty | +10.0% (Targeting China/HK products, effective from Nov 10, 2025) |
| Total Tax Rate | 14.5% |
| Tax Calculation | CIF Value × 14.5% |

| Legal Basis Path | IEEPA:9903.01.24 → USITC:6406.10.90.40 |
📌 Note:
- This code applies when the product is specifically described as "removable insoles, heel pads, and similar articles" without specific material designation.
- The base tariff is 4.5%, plus the 10% IEEPA surcharge, totaling 14.5%.
- This is higher than 6406.90.90.00 due to the higher base rate. Use this code only if the product description strictly matches "removable insoles/heel pads."
🎯 3. 9021.90.81.00 —— Parts & Accessories of Orthopedic Appliances (Medical Category)
| Item | Content |
|---|---|
| Base Tariff | 0.0% |

📌 Important:
- If the height-increasing insole is marketed as a medical device (e.g., for orthopedic correction), it falls under Chapter 90.
- Despite being a medical device, it still incurs the 10% IEEPA surcharge.
- Advantage: No base tariff (0%), but requires FDA registration or medical device compliance documentation, which adds complexity to customs clearance.
- Use this code only if the product has clear medical/orthopedic certification or labeling.
🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Guide)
✅ 1. Required Documentation Checklist (All Mandatory)
| Document | Required | Explanation |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Details material (EVA, Rubber, etc.), thickness, lift height, and intended use |
| ✅ Product Photos (with Label) | ✔️ | Clear view of brand, model, and any medical/disclaimer labels |
| ✅ Commercial Invoice | ✔️ | Must clearly state "Height-Increasing Insoles" and HS Code |
| ✅ Packing List | ✔️ | Describe contents accurately; avoid vague terms like "Shoe Parts" without specifics |
| ✅ Medical Device Certification (if applicable) | ✔️ | If claiming HS Code 9021.90.81.00, provide FDA registration or orthopedic certification |
| ✅ Origin Certificate | ✔️ | If claiming non-China origin (e.g., Vietnam), to avoid IEEPA duties |
✅ 2. Declaration Tips (Key Mantra)
🔥 "Material Dictates Code, Medical Claims Require Proof, IEEPA is Non-Negotiable!"
| Scenario | Correct Declaration | Wrong Approach |
|---|---|---|
| General EVA/Rubber Insoles | 6406.90.90.00 (10% Total) |
Misdeclare as Medical → Rejected |
| Heel Pads/Removable Lifts | 6406.10.90.40 (14.5% Total) |
Misdeclare as General → Overpay/Underpay |
| Orthopedic Correction Insoles | 9021.90.81.00 (10% Total) |
Misdeclare as General → FDA Compliance Issue |
| Any China-Origin Insoles | Always include IEEPA 10% | Try to hide origin → Seizure/ fines |
✅ 3. Special Case Handling
| Scenario | Recommendation |
|---|---|
| OEM Custom Insoles | Provide client design specs to avoid "misdescription" penalties |
| Insoles with Medical Claims | Must file under 9021.90.81.00 and provide medical documentation |
| Mixed Shipments | Declare each HS Code separately; do not bundle medical and non-medical items |
| Non-China Origin | If sourced from Vietnam/Mexico, apply for IEEPA exemption (0% additional duty) |

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
