π§ͺ Gutta Percha Rubber Strip: The "Ancient" Rubber with Modern Tariff Traps
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Compliance Strategy
π I. Product Definition & Classification: What is Gutta Percha Rubber?
Gutta Percha is a natural thermoplastic latex obtained from the sap of trees in the Palaquium genus. Unlike synthetic rubber (Section 40), it is distinct in chemical composition but is often treated similarly in trade classification when processed into strips or sheets.
However, crucial distinction:
- Gutta Percha itself is primarily used for golf ball covers, electrical insulation, and dental applications.
- "Rubber Strip" generally refers to vulcanized or unvulcanized rubber profiles.
β οΈ Key Classification Point:
- If the product is raw Gutta Percha or modified Gutta Percha in primary forms, it may fall under Chapter 40 (Rubber and Articles Thereof) depending on processing.
- If it is vulcanized rubber (including Gutta Percha-based compounds) in strip form, it falls under Heading 4016.
- If it is unvulcanized synthetic rubber mixed with Gutta Percha or oil-derived factice, it falls under Heading 4002.
Note: The provided data focuses on 4002 (Synthetic Rubber/Factice) and 4016 (Other Articles of Vulcanized Rubber). We will map "Gutta Percha Rubber Strip" to the most likely HS Codes in the provided
<DATA>based on common trade practices.

4002.91.00.00 |
Synthetic rubber and factice derived from oils, in primary forms or in plates, sheets or strip: Other: Latex | Latex form of Gutta Percha or synthetic rubber (if in liquid/latex state) | 25.0% |
4016.99.05.00 |
Other articles of vulcanized rubber other than hard rubber: Other: Other: Household articles not elsewhere specified or included | Vulcanized Gutta Percha strips for household use (if not elsewhere classified) | 0.0% |
4016.99.10.00 |

9018.39.00.40 |
Other Bougies, catheters, drains and sondes... Other | Medical Gutta Percha used in medical devices | 0.0% |
π Critical Analysis:
- Most Likely HS Code: If "Gutta Percha Rubber Strip" is unvulcanized and used as a raw material, it is often classified under 4002.99.00.00 (if considered synthetic/oil-derived factice) or potentially 4005/4006 (not in provided data). However, based on the provided list, 4002.99.00.00 is the closest for raw strips.
- If vulcanized, it falls under 4016.99.05.00 (0% tax) if not specifically for handles/knobs.
- Medical Use: If used for dental or medical catheters, 9018.39.00.20 or 9018.39.00.40 applies (0% tax).

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