π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional-Level Clearance Strategy
π I. Product Definition and Classification: What Exactly is "Oil Soluble NBR Compound"?
Nitrile Butadiene Rubber (NBR) is a synthetic rubber copolymer of acrylonitrile and butadiene, known for its excellent resistance to oils, fuels, and other chemicals. The term "Oil Soluble NBR Compound" typically refers to NBR processed into a form that can be dispersed in oil-based media or used as a compounding ingredient in oil-contamination-resistant applications. However, in international trade classification, the key determinants are physical state (solid/powder/granule vs. liquid/emulsion) and processing status (vulcanized vs. unvulcanized).
β οΈ Key Distinction Points:
- If it is solid NBR (blocks, flakes, powder) used as raw material β Often classified under Chapter 40 (Rubber) or Chapter 39 (Plastics/Resins) depending on exact form and trade practice.
- If it is an emulsion or latex β Classified under 4002.59 or 4005.
- If it is pre-compounded and vulcanized β Classified under 4016.99 (other vulcanized rubber articles), but "oil soluble compound" usually implies raw material stage.
- Crucial Note: "Oil soluble" is a performance characteristic, not a primary classifier. Customs looks at physical form and chemical composition.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided , here are the possible HS Codes and their rationales:
| HS Code | Product Description | Rationale from Data | Applicable Scenario |
|---|---|---|---|
3911.90.91.10 |
Synthetic resins and other polymers, n.o.s. | "Nitrile rubber belongs to synthetic rubber category, classified under chemicalεζη products like petroleum resins, polysulfides, etc." | When classified as a chemical synthetic product/resin rather than rubber proper (less common for standard NBR). |
4005.99.00.00 |
Unvulcanized rubber compounds, other | "Nitrile rubber is unvulcanized synthetic rubber, meets material requirements, classified under 'other'." | Unvulcanized NBR compound in non-specific forms (e.g., powders, granules not covered by 4002/4005.20). |
4005.20.00.00 |
Unvulcanized rubber compounds in primary forms | "Material is rubber, form is primary (raw material), matches unvulcanized mixed rubber characteristics." | Unvulcanized NBR in primary physical forms (e.g., lumps, flakes, powder) before final molding. |
3911.90.10.00 |
Synthetic rubber/elastomers | "Nitrile rubber is synthetic rubber/elastomer material, matches definition in this code." | Alternative classification focusing on elastomeric nature under Chapter 39. |
4002.59.00.00 |
Other unsaturated nitrile rubber (NBR) | "Product name is explicitly Nitrile Rubber, matches material exactly." | Unvulcanized NBR in primary forms (latex, granules, blocks) β Most Common for Raw NBR. |
4002.51.00.00 |
Nitrile rubber (NBR) in primary forms | "Material is NBR, matches exactly, inferred as primary form or latex." | Unvulcanized NBR latex or dispersion (if "oil soluble" refers to latex dispersion). |
π Critical Reminder:
- "Oil Soluble" does not change the HS Code structure. It is a chemical property.
- Unvulcanized state is key: Most NBR compounds for manufacturing are unvulcanized β Chapter 40.
- If the product is a final vulcanized part (e.g., seals, gaskets), it would fall under 4016, but "compound" implies raw material.
- Discrepancy Note: Codes3911.90...suggest classification as plastic/resin, while4002/4005are rubber. NBR is technically a rubber, so 40xx series is more accurate unless specific trade practices dictate otherwise.

β 2. Declaration Tips (Key Mnemonics)
π₯ "Unvulcanized = Chapter 40; Primary Form = 4002/4005; 'Oil Soluble' is Property, Not Code!"
| Scenario | Correct Declaration | Wrong Approach |
|---|---|---|
| Solid NBR blocks/powder | 4002.59.00.00 or 4005.20.00.00 |
Misclassify as 3911 β Higher scrutiny. |
| NBR Latex/Dispersion | 4002.51.00.00 |
Call it "liquid rubber" without specifying latex β Delays. |
| Vulcanized NBR parts | 4016.99 |
Declare as "compound" β Classification error. |
| General NBR Compound | 4002.59.00.00 |
Use vague term "rubber" β Customs reclassification β 35%+ penalties. |
β 3. Special Cases Handling
| Case | Handling Suggestion |
|---|---|
| NBR Latex (Water-based) | Use 4002.51.00.00. Ensure invoice says "Latex". |
| NBR Solution (Solvent-based) | Still 4002.59.00.00 or 4005. Clarify state. |
| "Oil Soluble" Emulsion | If itβs a dispersion, use 4002.51.00.00. If solid after processing, use 4005. |
| Blended with Other Polymers | Must declare as "NBR Compound" and specify % content. If >50% NBR, 4002 applies. |
π V. Global Market Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (CN Origin) | Certification | Notes |

~6-8% | None | Lower base tariff, no US surcharges. |
| πͺπΊ EU | 4002.59.00.00 |
0% | REACH | No surcharges, but REACH registration required. |
| π¬π§ UK | 4002.59.00.00 |
0% | UKCA/REACH | Post-Brexit alignment with EU standards. |
| π―π΅ Japan | 4002.59.00.00 |
0-3% | JIS | Favorable under Japan-China EPA. |
π Conclusion:
- USA is the only major market imposing high additional tariffs (35%) on Chinese NBR.
- EU/UK/Japan are tariff-friendly but require chemical compliance (REACH, etc.).
- Supply Chain Strategy: Consider sourcing NBR from non-CN origins (e.g., South Korea, Thailand) for US-bound goods to avoid 35% tariff.
π VI. Common Mistakes & Pitfalls (Blood & Tears Lessons)
β Mistake 1: Classifying unvulcanized NBR under 3911 (Plastics) |
π Consequence: Higher scrutiny, potential reclassification to 4002, delays, and possible penalties.
β Mistake 2: Ignoring "Unvulcanized" status |
π Consequence: If vulcanized, should be 4016 (Tariff varies). Misclassification leads to back-taxes.
β Mistake 3: Not specifying ACYRILTRONITRILE CONTENT |
π Consequence: NBR grades vary (high/medium/low AN content). Customs may request detailed specs, causing delays.
β Mistake 4: Using "Rubber Compound" without details |
π Consequence: Too vague. Must specify "Nitrile Butadiene Rubber" and physical form.
β Correct Practice:
"Unvulcanized Nitrile Butadiene Rubber (NBR) Compound, Powder Form, 33% Acrylonitrile Content, For Manufacturing Oil-Resistant Seals, HS 4002.59.00.00"
π― VII. Conclusion: Professional Declaration, Cost Efficiency, Risk Mitigation
π― Remember the Mantra:
πΉ "Unvulcanized NBR = 4002/4005; Base 0% + 35% Surcharge; Total 35%."
πΉ "Oil Soluble is Property, Not Code; Physical Form Decides."
πΉ "Chapter 39 vs 40: Rubber Belongs to 40; Misclassification Costs 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) 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
