🧪 Oil Impregnated Nitrile Butadiene Rubber (NBR)
🌐 HS Code Reference & Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
📌 I. Product Definition & Classification: Do You Really Understand "NBR"?
Nitrile Butadiene Rubber (NBR) is a synthetic rubber copolymer of acrylonitrile (ACN) and butadiene. It is renowned for its exceptional resistance to oils, fuels, and other chemicals, while maintaining good mechanical strength. In international trade, "Oil Impregnated Nitrile Rubber" refers to NBR materials that have been saturated or treated with oil to enhance flexibility, plasticity, or specific processing characteristics.
In the context of US Customs classification, the form of the rubber determines the HS Code: * Latex/Emulsion Form: Liquid or semi-liquid state (e.g., Oil-soluble NBR latex). * Solid/Form Shape: Raw forms such as sheets, blocks, rods, or mixtures (e provided as raw materials for further processing). * Finished/Semi-Finished Parts: Specific articles like gaskets or seals (if vulcanized and cut to shape).
⚠️ Key Distinction:
- If the product is a liquid latex/emulsion →归类 to 4002.51.00.00 / 4002.59.00.00
- If the product is a solid sheet/block/mixture →归类 to 4002.80.00.00 / 4002.91.00.00
- If the product is a vulcanized finished part (e.g., seal) →归类 to 4016.93.50.20

🛠️ IV. Clearance Practical Advice (Battle-Tested Pitfall Avoidance Guide)
✅ 1. Required Documentation Checklist (No Omissions)
| Document | Required | Description |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must detail ACN content (%), oil content, viscosity, state (liquid/solid), and HS Code justification. |
| ✅ Chemical Composition Report | ✔️ | Proves material is NBR (Acrylonitrile-Butadiene Rubber) and not another synthetic rubber. |
| ✅ Product Photos | ✔️ | Clearly show state: Emulsion (liquid), Sheet/Block (solid), or Finished Seal. |
| ✅ Commercial Invoice | ✔️ | Must explicitly state: "Nitrile Butadiene Rubber, Oil-Impregnated, Form: [Latex/Sheet/Part]". |
| ✅ Packing List | ✔️ | Detail net/gross weight. For liquids, specify volume and container type. |
| ✅ Certificate of Origin (CO) | ✔️ | Required for US import. If not from China, may reduce/eliminate surcharges. |
✅ 2. Declaration Tips (Key Mantras)
🔥 "Form Determines Code, State Dictates Tax, Name Must Be Precise!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Liquid NBR Latex | 4002.51.00.00 or 4002.91.00.00 |
Declare as "Rubber Sheet" → Customs Rejection |
| Solid NBR Sheet/Block | 4002.80.00.00 |
Declare as "Finished Part" → 37.5% instead of 35% |
| Vulcanized Seal | 4016.93.50.20 |
Declare as "Raw Material" → Undervaluation Risk |
| Mixed NBR/Latex | 4002.59.00.00 |
Ambiguous description → Delay for Inspection |
✅ 3. Special Case Handling
| Case | Handling Advice |
|---|---|
| Oil Content Variation | If oil content is high, ensure it is still classified as "Rubber" and not "Grease" or "Lubricant". NBR with oil is still rubber. |
| Vulcanization Status | Crucial: If the rubber is unvulcanized (raw), use 4002 series. If vulcanized (finished), use 4016 series. Mistaking raw for finished can lead to false declarations. |
| Import from China | All 5 HS codes attract 35% or 37.5% total duty. No de minimis exemption. Budget accordingly. |
| Import from Non-China (e.g., Vietnam) | Verify if IEEPA 10% surcharge applies. If origin is not China, base duty and Section 301 may differ. Check for USMCA or other FTAs. |
🌍 V. Global Market Clearance Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Duty (China Origin) | Certification | Notes |
|---|---|---|---|---|
| 🇺🇸 USA | 4002.51.00.00 |
35.0% | N/A | High surcharge. Verify form. |
| 🇨🇳 China | 4002.51.00.00 |
5.5% | N/A | Lower base duty. |
| 🇪🇺 EU | 4002.51.00.00 |
6.5% | REACH | No Section 301 surcharge. |
| 🇦🇺 Australia | 4002.51.00.00 |
5.0% | N/A | Lower duty. |
📌 Conclusion:
- USA has the highest duty burden for NBR imports from China due to Section 301 + IEEPA. - Raw Material (Latex/Sheet): 35% duty. - Finished Part (Seal): 37.5% duty. - Cost Impact: Significant. Consider supply chain diversification if margins are thin.
📌 VI. Common Mistakes & Pitfall Guide (Blood & Tears Lessons)
❌ Mistake 1: Declaring Raw NBR Sheets as Finished Rubber Parts (4016.93.50.20)
👉 Consequence: You pay 37.5% instead of 35%. Small difference, but indicates poor classification practice.
❌ Mistake 2: Declaring NBR Latex as Chemical Adhesive or Lubricant
👉 Consequence: Wrong HS Code → Customs Seizure or Penalty. NBR Latex is rubber, not just a chemical mix.
❌ Mistake 3: Ignoring Oil Content
👉 Consequence: If oil content is extremely high, customs may reclassify as "Grease" or "Preparation". NBR must retain its rubber character.
✅ Correct Practice:
"Nitrile Butadiene Rubber (NBR) Latex, Oil-Impregnated, Acrylonitrile Content XX%, Viscosity YY, For Industrial Use, HS 4002.51.00.00"
🎯 VII. Conclusion: Precise Classification, Cost Control, Efficiency!
🎯 Remember the Mantra:
🔹 "Latex goes to 4002.5x, Solid Raw to 4002.8x/91, Finished Seals to 4016.93."
🔹 "China Origin = 35% (Raw) / 37.5% (Finished). No De Minimis!"
🔹 "Define Form, Define Use, Define Origin. Save Money, Clear Fast."
📌 Pro Tip:
- If your NBR is imported from a country with a Free Trade Agreement (FTA) with the US (e.g., Australia, Canada), check if the 301/IEEPA surcharges are exempt.
- Apply for a Binding Ruling if your product is on the borderline between raw rubber and finished part. Avoids post-entry audits.
📣 Immediate Action:
📞 Consult a Customs Broker + Provide Product Sample/Photos + Get HS Code Ruling
🚀 Ensure your NBR import, Smooth Clearance, Profit Maximization!
✨ Professional Clearance Starts with Accurate Classification!
💼 Every Cent of Duty Saved is Pure Profit!

关于 HS 编码归类
协调制度（HS）是由世界海关组织（WCO）制定的国际贸易商品分类标准。全球 200 多个国家采用 HS 系统作为海关关税、贸易统计和进出口监管的基础。
每个 HS 编码遵循以下层级结构：
- 章（2 位）——商品大类（例如：第 84 章：机器和机械设备）
- 品目（4 位）——章内的更具体分类
- 子目（6 位）——国际通用细分，所有 WCO 成员国统一使用
- 本国细分（8-10 位）——各国自行扩展的细分编码，如美国 HTSUS 10 位编码
正确的 HS 编码归类对于顺利通关、准确缴纳关税和遵守贸易法规至关重要。错误归类可能导致海关延误、多缴关税或罚款。
从CN进口到US时，适用的关税税率可能包括：
- 最惠国（MFN）税率——适用于 WTO 成员国的标准关税税率
- 普通税率——适用于无贸易协定国家
- 贸易救济关税——附加关税，如 301 条款（反倾销）、232 条款（国家安全）或反补贴税
