π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Level Entry Strategy
π I. Product Definition & Classification: Do You Really Understand "Synthetic Rubber"?
Low Cis 1,4 Polybutadiene (BR) is a high-performance synthetic rubber known for its excellent abrasion resistance, low heat generation, and superior wet grip. It is primarily used in tire manufacturing (especially radial tires), shoe soles, and various industrial rubber products.
In international trade, it falls under Chapter 40 (Rubber and Articles Thereof). Specifically, it is classified as a Butadiene Rubber (BR) in primary forms.
β οΈ Key Distinction:
- If the product is "Low Cis 1,4 Polybutadiene" (specifically defined by its cis-1,4 content, usually <40%), it is explicitly identified as Butadiene Rubber (BR).
- It is not Natural Rubber (Heading 4001).
- It is not a mixed product with other rubbers unless specifically stated; however, the HS code provided in the data covers mixtures of 4001 with this heading, but pure BR has its own specific code.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authoritative Comparison)
Based on the provided data, here is the precise classification:
| HS Code | Product Description | Applicable Scenario | Key Characteristics |
|---|---|---|---|
4002.20.00.00 |
Synthetic rubber and factice derived from oils... Butadiene rubber (BR) | Raw synthetic rubber, primary forms (blocks, lumps, powder, granules, flakes) | Pure or mixed Butadiene Rubber |
4002.99.00.00 |
Other synthetic rubber and factice derived from oils (Not listed in data but for context) | Other synthetic rubbers (e.g., SBR, NBR not specified as BR) | Not applicable to Low Cis BR |
4001.00.00.00 |
Natural rubber, balata, gutta-percha, guayule, chicle, and similar natural gums (Not listed in data) | Natural rubber | Not applicable |
π Focus Reminder:
- Only4002.20.00.00applies to "Low Cis 1,4 Polybutadiene" as it is a specific type of Butadiene Rubber (BR).
- The description in the data explicitly lists: "Butadiene rubber (BR)" under this code.
- Do not misclassify as other synthetic rubbers (like SBR) which might have different tariff implications if the data were different, but strictly here, BR = 4002.20.00.00.

π Explanation:
- The Base Tariff for Butadiene Rubber is 0%, reflecting its status as a key industrial raw material.
- However, due to trade tensions, a Section 301 Additional Tariff of 25% is applied to Chinese-origin goods in this category.
- Total Duty Rate = 25%.
- This is a significant cost factor for exporters from China.
π οΈ IV. Customs Clearance Practical Advice (Pitfall Avoidance Guide)
β 1. Required Documentation Checklist
| Document | Must Provide | Description |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must specify "Low Cis 1,4 Polybutadiene" and the exact cis-1,4 content % (e.g., <40%). |
| β Certificate of Analysis (COA) | βοΈ | Confirms it is Butadiene Rubber (BR) and not a different synthetic rubber. |
| β Commercial Invoice | βοΈ | Clearly state: "Synthetic Rubber, Low Cis 1,4 Polybutadiene, HS Code 4002.20.00.00" |
| β Bill of Lading | βοΈ | Describe goods as "Polybutadiene Rubber (BR) in primary forms" |
| β Origin Certificate | βοΈ | If originating from China, subject to 25% tariff. If from other countries (e.g., US, Korea), verify if FTAs apply. |
β 2. Declaration Tips (Key Mantra)
π₯ "Specify 'Low Cis', Declare 'BR', Avoid 'General Synthetic'"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Pure Low Cis 1,4 BR | 4002.20.00.00 + "Butadiene Rubber (BR)" |
General "Synthetic Rubber" β Risk of reclassification |
| Mixed with Natural Rubber | 4002.20.00.00 if BR is predominant |
Misdeclaring as natural rubber |
| Powder/Granule Form | Primary forms under 4002.20.00.00 |
Declaring as "finished goods" |
| Non-Chinese Origin | Check for zero tariff if from FTAs | Assuming 25% for all origins |
β 3. Special Situation Handling
| Situation | Handling Advice |
|---|---|
| High Purity vs. Compound | If it is a pre-compounded rubber with fillers, it may move to 4005 (Compounded Rubber). Ensure it is raw rubber (primary form) for 4002.20. |
| Different Cis Content | "Low Cis" (<40%) is BR. "High Cis" (>90%) is also BR. Both fall under 4002.20.00.00. |
| Origin Change | If shipped from Vietnam or Malaysia, check if it is substantially transformed. If not, it may still be deemed Chinese origin and subject to 25%. |
| Tariff Exclusion | Check if the specific product/manufacturer is eligible for Section 301 Exclusions (though many synthetic rubber exclusions have expired or been limited). |
π V. Global Market Customs Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Key Requirements | Note |
|---|---|---|---|---|
| πΊπΈ USA | 4002.20.00.00 |
25% (301 Tariff) | FDA (if food contact), CPSIA (if toys) | High duty cost |

π Conclusion:
- USA is the only major market imposing a 25% surcharge on Chinese-origin BR.
- EU and Asia offer 0% tariffs but require strict chemical safety compliance (REACH, etc.).
π VI. Common Errors & Pitfall Guide (Lessons Learned)
β Error 1: Declaring as "Natural Rubber"
π Consequence: Misclassification, fines, and potential seizure. BR is synthetic.
β Error 2: Using "General Synthetic Rubber" without specifying BR
π Consequence: Customs may question the rate. While the rate might be the same, transparency prevents delays.
β Error 3: Ignoring Section 301 Exclusions
π Consequence: Paying 25% when an exclusion might have applied (if eligible).
π Action: Check the USTR exclusion list for your specific product type and manufacturer.
β Error 4: Misdeclaring Primary Form
π Consequence: If itβs a compound (4005), the code changes. Ensure it is raw, unvulcanized rubber.
β Correct Practice:
"Low Cis 1,4 Polybutadiene Rubber (BR), Raw, Primary Form, Cis-1,4 Content <40%, HS Code 4002.20.00.00"
π― VII. Conclusion: Precise Declaration, Cost Control!
π― Key Takeaway:
πΉ HS Code:
4002.20.00.00
πΉ Total US Tariff: 25% (0% Base + 25% Section 301)
πΉ Critical Action: Verify Origin and Product Specification (Low Cis BR).πΉ "Low Cis BR is BR, not Natural. 25% Tariff in US, Zero in EU. Declare precisely!"
π Pro Tip:

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
