🌿 Natural Rubber, CV Grade (Technically Specified Natural Rubber - TSNR)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Level Strategy
📌 I. Product Definition and Classification: Do You Really Understand "Natural Rubber CV"?
Natural Rubber CV (Coagulated Latex) belongs to the category of Technically Specified Natural Rubber (TSNR). It is a standardized natural rubber product produced by coagulating rubber latex and then processing it into plates, sheets, or strips. Unlike traditional block rubber (ribbed smoked sheet), CV grade is characterized by high purity, low ash content, and consistent viscosity.
In international trade, it is primarily classified under Heading 4001 ("Natural rubber, balata, gutta-percha, guayule, chicle and similar natural gums, in primary forms or in plates, sheets or strip").
⚠️ Key Distinction Point:
- If the product is in primary forms (plates, sheets, or strips) →归入 4001
- If it is further processed into specific goods (e.g., tires, gloves) →归入 different chapters (e.g., 4011, 4015)
- CV Grade specifically refers to a technical specification within TSNR, often requiring specific testing for viscosity and impurities.

💰 III. 2026 Latest Tariff Rate Details (Including Surtax and Policy Surcharges)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Time: Current as of 2026 tariff schedule
🎯 1. 4001.22.00.50 —— Natural Rubber, TSNR Grade CV
| Item | Content |
|---|---|
| Base Tariff Rate | 0.0% (ad valorem) |
| Additional Tariff (Section 301) | +25.0% |
| Total Tariff Rate | 25.0% |
| Tax Calculation | CIF Value × 25% |
| De Minimis Exemption | ❌ Not Eligible (Subject to full tariff) |
| Legal Basis | USITC Section 301 Action on Chinese Imports |
📌 Explanation:
- Base Rate: Natural rubber generally enjoys a low or zero base duty due to its raw material status.
- Additional Surtax: The +25% rate is a punitive tariff imposed under Section 301 of the Trade Act of 1974 against Chinese goods.
- Total Burden: The effective tax rate is 25%, which significantly increases the cost of imported CV grade rubber.
- No Exemptions: Unlike some consumer electronics, raw rubber materials in this category do not qualify for de minimis exemptions or broad exclusions under current policies.
🎯 2. 4001.22.00.10 —— Natural Rubber, TSNR Other
| Item | Content |
|---|---|
| Base Tariff Rate | 0.0% |
| Additional Tariff (Section 301) | +25.0% |
| Total Tariff Rate | 25.0% |
| Tax Calculation | CIF Value × 25% |
| De Minimis Exemption | ❌ Not Eligible |
| Legal Basis | USITC Section 301 Action on Chinese Imports |
📌 Note:
- Even though this HS Code is labeled "Other," the tariff structure is identical to CV Grade.
- Both4001.22.00.10and4001.22.00.50are subject to the same 25% total tariff.
- Therefore, the distinction between CV and "Other" TSNR does not affect the tax burden in this scenario, but proper classification is still critical for customs compliance.
🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance)
✅ 1. Required Documentation Checklist (Must-Have)
| Document | Required | Description |
|---|---|---|
| ✅ Certificate of Origin (CO) | ✔️ | Essential for proving origin (China) and applying correct Section 301 rates. |
| ✅ Product Specification Sheet | ✔️ | Must detail: Grade (CV), Type (TSNR), Form (Plates/Sheets/Strip), Viscosity, Mooney Value, Ash Content. |
| ✅ Commercial Invoice | ✔️ | Must explicitly state: "Natural Rubber, Technically Specified, Grade CV, HS Code 4001.22.00.50". |
| ✅ Bill of Lading | ✔️ | Clear description of goods, weight, and package count. |
| ✅ Test Report (Third-Party) | ✔️ | Recommended to prove it meets TSNR CV standards (e.g., DIN 50019). |
| ✅ Import License | ❓ | Check if specific agricultural/raw material import licenses are required in your destination port. |
✅ 2. Declaration Tips (Key Mantra)
🔥 "Raw Material Status, Clear Grade, Accurate HS, Avoid Penalty!"
| Situation | Correct Declaration | Wrong Practice |
|---|---|---|
| CV Grade Rubber | 4001.22.00.50 - "Natural Rubber, TSNR, Grade CV" |
Misclassifying as 4001.10.00.00 (Latex) → Incorrect tax basis. |
| Rubber in Blocks | Ensure it falls under "Plates, Sheets, or Strip" in Heading 4001. | Declaring as "Finished Rubber Goods" (e.g., tires) → Wrong chapter. |
| Mixed Shipments | Separate CV from other grades if possible for clarity. | Bundling CV and non-CV TSNR without clear distinction → Customs scrutiny. |
✅ 3. Special Circumstances Handling
| Situation | Handling Advice |
|---|---|
| High Tariff Cost | Consider if the product can be sourced from non-China origins (e.g., Thailand, Indonesia) to avoid the 25% surtax, if feasible. |
| Origin Fraud | Strictly avoid "transshipment" fraud. Customs uses advanced analytics to detect Chinese-origin goods misrepresented as Southeast Asian. Penalties are severe. |
| Product Quality Disputes | Ensure the "CV Grade" claim is backed by test reports. If customs doubts the grade, they may reclassify it, leading to delays. |
| Section 301 Exclusions | Check if the specific HS Code has any temporary exclusions. Currently, 4001.22 is largely not excluded. |

📌 VI. Common Mistakes & Pitfall Guide (Lessons Learned)
❌ Mistake 1: Declaring CV Rubber as "Latex" (HS 4001.10)
👉 Consequence: Incorrect classification. Latex and TSNR are different physical forms. Customs may demand reclassification and impose penalties.
❌ Mistake 2: Failing to Specify "Grade CV"
👉 Consequence: Customs may use the "Other" code (4001.22.00.10) or apply a general default, potentially triggering additional scrutiny or delays.
❌ Mistake 3: Under-Declaring Value to Reduce Tax
👉 Consequence: Customs valuation disputes. CIF value must include freight and insurance. Falsification leads to heavy fines and loss of trust.
❌ Mistake 4: Ignoring Section 301 Impact
👉 Consequence: Unexpected 25% cost increase at the border, eroding profit margins completely.
✅ Correct Practice:
"Natural Rubber, Technically Specified (TSNR), Grade CV, In Sheets, Origin: China, HS Code: 4001.22.00.50"
🎯 VII. Conclusion: Professional Declaration, Save Time, Reduce Costs!
🎯 Remember the Mantra:
🔹 "CV Grade is TSNR, HS 4001.22.50, 25% Surtax in US, No Escape!"
🔹 "Clear Docs, Accurate Origin, Avoid Fraud, Sleep Well at Night!"
📌 Pro Tip:
If your rubber is sourced from Thailand, Indonesia, or Malaysia, you can avoid the 25% US surtax entirely (tariff remains 0%).

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
