🌲 Gutta Percha Strip (Natural Polymer Latex)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Strategy
📌 One, Product Definition and Classification: Do you really understand “Gutta Percha”?
Gutta Percha is a natural thermoplastic material obtained from the latex of trees belonging to the Palaquium genus (mainly Palaquium gutta). It was historically used for telegraph cable insulation and golf balls. Today, it is primarily used in dental applications (root canal filling) and specialized industrial seals.
In international trade, it is classified based on its processing level and end-use:
1. Raw/Processed Gutta Percha (Unmanufactured or Semi-Manufactured):
- Blocks, granules, or strips not yet shaped into specific dental or industrial tools.
- HS Codes: 3913.90.00.00 (Other natural polymers) or 3901/3902/3903/3904/3905/3906/3907/3908/3909/3910 (depending on specific chemical nature, but 3913.90.00.00 is most common for natural latex polymers).
⚠️ Key Distinction Point:
- If the strip is raw gutta percha or mixed with other materials but not yet a dental instrument → 3913.90.00.00
- If the strip is pre-shaped for dental use (e.g., cone-shaped points for root canals) → 9018.49.00.00 (Dental instruments)
- If the strip is used for industrial sealing (not dental) → 3913.90.00.00
📦 Two, HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Is it a Dental Instrument? |
|---|---|---|---|
3913.90.00.00 |
Other natural polymers, in primary forms or in plates, sheets, or strip | Raw gutta percha strips, industrial seals, adhesives | ❌ No |
9018.49.00.00 |
Other dental instruments and appliances (incl. light sources) | Pre-shaped gutta percha cones for root canal filling | ✅ Yes |
3921.90.00.00 |
Other plates, sheets, film, foil, and strip (plastics) | If gutta percha is mixed with synthetic plastics | ❌ No |
3006.93.00.00 |
Dental cement; other dental preparations | Gutta percha mixed with zinc oxide as a temporary filling | ❌ No |
🔍 Key Reminder:
- Dental gutta percha points (cones) are considered dental instruments and fall under 9018.49.00.00.
- Gutta percha strips (long, unshaped, or raw) are considered plastics/polymers and fall under 3913.90.00.00.
- Do not misclassify dental gutta percha as general plastic if it is pre-shaped for medical use.

📌 Six, Common Errors & Pitfall Avoidance Guide (Blood and Tears Lessons)
❌ Mistake 1: Declaring pre-shaped dental gutta percha cones as “plastic strips”
👉 Consequence: Tax rate increases due to misclassification → Back taxes + fines!
❌ Mistake 2: Declaring raw gutta percha strips as “dental instruments”
👉 Consequence: Unnecessary FDA inspection delays → Release delay or return!
❌ Mistake 3: Not providing MSDS for gutta percha
👉 Consequence: Customs unable to judge chemical safety → Delayed release or return
❌ Mistake 4: Using “Natural Polymer” as declaration name for dental instruments
👉 Consequence: Misclassification → Back taxes + late fees
✅ Correct Practice:
“Pre-shaped Gutta Percha Cones, Dental Use, Size 0.04, Sterile, Model XYZ, FDA Registered”
OR
“Raw Gutta Percha Strip, Industrial Seal, Non-Dental, Model ABC, MSDS Attached”
🎯 Seven, Conclusion: Professional Declaration, Save Time and Money!

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
