☀️ Rubber Sunscreen Additive (UV Stabilizers for Rubber)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy for US Import
📌 I. Product Definition & Classification: What is "Rubber Sunscreen Additive"?
Rubber Sunscreen Additives, scientifically known as UV Stabilizers or Hindered Amine Light Stabilizers (HALS), are chemical compounds added to rubber products to prevent degradation caused by ultraviolet (UV) radiation. These additives absorb or screen UV light, effectively extending the lifespan of rubber goods such as tires, hoses, seals, and outdoor equipment.
In international trade, these additives are classified based on their chemical nature: 1. Rubber Processing Chemicals: If they are specifically formulated mixes for rubber processing (e.g., unvulcanized rubber compounds). 2. Chemical Auxiliaries/Preparations: If they are generic chemical stabilizers or antioxidants not exclusive to rubber processing.
⚠️ Key Distinction Point:
- If the product is a pre-mix specifically for rubber processing (e.g., masterbatches for unvulcanized rubber) → Classified under Chapter 40 (Rubber).
- If the product is a generic chemical stabilizer/antioxidant used in rubber but not exclusive to it → Classified under Chapter 38 (Chemical Products).
📦 II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
| HS Code | Product Description | Application Scenario | Tax Category |
|---|---|---|---|
4005.99.00.00 |
Rubber Compounds: Other (Unvulcanized) | Unvulcanized rubber mixtures containing sunscreen additives; generic rubber compound categories. | Rubber Product |
3824.99.29.00 |
Chemical Preparations: Other | Chemical auxiliary agents; generic "chemical products and preparations" not elsewhere specified. | Chemical Product |
4005.91.00.00 |
Rubber Compounds: Other Specific Types | Rubber processing chemical additives falling under "unvulcanized rubber" related categories. | Rubber Product |
3812.39.90.00 |
Rubber Stabilizers: Other | Rubber materials; sunscreen additives classified as antioxidant preparations or other composite stabilizers. | Chemical Product |
3812.31.00.00 |
Chemical Stabilizers/Antioxidants | Rubber materials; sunscreen additives explicitly classified as chemical stabilizers/antioxidants. | Chemical Product |
🔍 Key Reminder:
- Chapter 40 (Rubber) codes (4005.xx) generally apply when the additive is part of a rubber compound mixture or specifically defined as a rubber processing material.
- Chapter 38 (Chemicals) codes (3812.xx,3824.xx) apply when the additive is a pure chemical auxiliary, such as a specific antioxidant or UV stabilizer sold as a chemical reagent, not a finished rubber mix.
- Misclassification Risk: Declaring a chemical stabilizer as a rubber compound (or vice versa) can lead to customs detention and reassessment of duties.
💰 III. 2026 Latest Tariff Rate Breakdown (Including Additional Taxes & Policies)
✅ Applicable Country: United States (US)
✅ Origin: China (CN)
✅ Effective Date: From November 10, 2025 (including subsequent imports)

- If the product is a pure chemical antioxidant (e.g., HALS) sold as a chemical reagent, this is the most precise classification within Chapter 38, but it carries the highest tariff (41.5%).
🛠️ IV. Customs Clearance Practical Advice (Real-World Pitfall Avoidance)
✅ 1. Preparation Checklist (Essential Documents)
| Document | Required | Notes |
|---|---|---|
| ✅ Product Specification Sheet | ✔️ | Must detail chemical composition, CAS number, and intended use (rubber stabilization). |
| ✅ Safety Data Sheet (SDS) | ✔️ | Must align with HS Code description; highlight "UV Stabilizer" or "Antioxidant" role. |
| ✅ Commercial Invoice | ✔️ | Clearly state "Rubber Sunscreen Additive" or "UV Stabilizer for Rubber." Avoid vague terms like "Chemical Mix." |
| ✅ Certificate of Origin (CO) | ✔️ | Required for confirming Chinese origin (subject to additional tariffs). |
| ✅ Packaging List | ✔️ | Detail net/gross weight and packaging type. |
| ✅ Technical Data Sheet (TDS) | ✔️ | Proof of chemical properties (e.g., absorption spectrum, stability). |
✅ 2. Declaration Strategy (Key Rules)
🔥 "Chemical Name, Clear Function, Avoid Ambiguity!"
| Scenario | Correct Declaration | Incorrect Practice |
|---|---|---|
| Pure Chemical Stabilizer (e.g., HALS) | 3812.31.00.00 or 3812.39.90.00 |
Misdeclare as rubber compound → Risk of penalty for wrong classification. |
| Pre-mixed Rubber Compound | 4005.91.00.00 or 4005.99.00.00 |
Misdeclare as pure chemical → May face lower base rate but risk of audit if not a mix. |
| Generic Chemical Auxiliary | 3824.99.29.00 |
Use vague terms like "Additive" without specifying function. |
| Sample Shipments | Still declare full value | Do not use "Sample" to avoid tariffs; Section 301 still applies. |
✅ 3. Special Case Handling
| Case | Handling Advice |
|---|---|
| OEM Custom Stabilizers | Provide contract or order details specifying client and usage to justify specific HS Code. |
| Multi-Use Chemicals | If used in rubber and plastics, declare based on primary use or most specific code (3812.xx). |
| Confusion between 3812 and 3824 | 3812 is for "Anti-knocking preparations, prepared dyes, pigments, and other chemical products... mainly used as antioxidants/stabilizers." 3824 is for "Other prepared binders..." Use 3812 if the primary function is stabilization/antioxidant. |
🌍 V. Global Market Clearance Comparison (2026 Latest)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Certification Requirements | Remarks |
|---|---|---|---|---|
| 🇺🇸 USA | 4005.99.00.00 (if rubber mix) or 3812.31.00.00 |
35% or 41.5% | No specific US certification required for raw additives. | Section 301 + IEEPA apply. |
| 🇨🇳 China | 3812.31.00.00 |
6.5% | No specific certification for export. | Low base rate, no additional US tariffs. |
| 🇪🇺 EU | 3812.31.00.00 |
6.5% | REACH Registration required for chemical substances. | No additional tariffs for China. |
| 🇦🇺 Australia | 3812.31.00.00 |
5% | No specific certification. | Low tariff, easy clearance. |
| 🇯🇵 Japan | 3812.31.00.00 |
6.5% | No specific certification. | Low tariff. |
📌 Conclusion:
- USA is the most challenging market due to Section 301 and IEEPA tariffs.
- Chapter 40 codes (Rubber) offer a 35% total rate, which is 6.5%-6.5% lower than Chapter 38 chemical codes (40%-41.5%).
- If the product can be legally classified as a rubber compound/additive mix, choose 4005.xx to save costs.
- If it is a pure chemical, 3812.xx is better than 3824.xx (40% vs 41.5%).
📌 VI. Common Errors & Pitfall Guide (Lessons Learned)
❌ Error 1: Using vague description "Rubber Additive" without specifying "UV Stabilizer" or "Antioxidant"
👉 Consequence: Customs may classify under the highest duty code (3824.99.29.00 at 41.5%) or hold for further inspection.
❌ Error 2: Classifying pure chemical stabilizers as rubber compounds (4005.xx)
👉 Consequence: Risk of customs audit, fines, and potential reclassification to chemical codes with penalties.
❌ Error 3: Assuming "De Minimis" exemption applies for small shipments
👉 Consequence: De Minimis is denied for these HS Codes from China. Even small shipments are subject to full tariffs.
❌ Error 4: Confusing "Sunscreen" (for skin) with "UV Stabilizer" (for rubber)
👉 Consequence: Wrong HS Code (e.g., under cosmetics Chapter 33), leading to major compliance violations.
✅ Correct Practice:
"UV Stabilizer for Rubber, HALS Type, Chemical Auxiliary, CAS No. XXXX-XX-X, Intended for Rubber Processing."
🎯 VII. Conclusion: Precise Classification for Cost Savings
🎯 Key Takeaway:
🔹 "Rubber Mix = 35%, Chemical Stabilizer = 40-41.5%, Pure Chemical = 41.5%"
🔹 "Chapter 40 is cheaper than Chapter 38 for similar functions."
🔹 "Always specify chemical function (Antioxidant/UV Stabilizer) to avoid generic high-duty codes."
📌 Pro Tip:
If your product is a custom blend for rubber processing, insist on classification under
4005.99.00.00or4005.91.00.00to secure the 35% rate.
If it is a pure chemical, use3812.39.90.00(40%) instead of3824.99.29.00(41.5%) if possible.
Always apply for a Pre-Ruling (Advance Ruling) from US Customs if the classification is borderline.
📣 Immediate Action:
📞 Consult with a licensed customs broker.
📄 Provide detailed Technical Data Sheets (TDS) and Safety Data Sheets (SDS).

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
