🧪 MBS Rubber Additive (Powder)
🌐 HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Strategy
📌 I. Product Definition & Classification: What exactly is MBS Rubber Additive?
MBS (often referring to specific chemical formulations like Dibenzylidene Sorbitol or specialized sulfide additives in rubber processing) is a critical chemical auxiliary used in the rubber industry. It functions as a processing aid, antioxidant, or activator. In international trade, its classification depends heavily on its chemical nature, physical form (Powder), and primary function.
Based on the provided data, there are 4 distinct HS Code possibilities. The choice determines your tax burden significantly.
⚠️ Key Distinction Points:
- Is it a generic chemical mixture for rubber? → Likely3824.99.29.00or3824.99.93.97
- Is it a specific organic sulfur compound? → Likely2930.20.90.20or2930.20.20.10
- Crucial: The distinction between "Chemical Preparations" (Ch. 38) and "Organic Chemicals" (Ch. 29) is the single biggest factor in tax optimization.
📦 II. HS Code Classification Details (2026 Latest Tariff Authority)
| HS Code | Product Description | Primary Classification Logic | Tax Rate (Total) |
|---|---|---|---|
3824.99.29.00 |
Rubber Additive DBS (Powder) - Chemical Preparation | Classified as a Chemical Product/Preparation. Material: Chemical additive. Form: Powder. | 41.5% |
2930.20.90.20 |
Rubber Additive DBS (Powder) - Organic Sulfur Compound | Classified as a Thiocarbamate Organic Sulfur Compound. Used in rubber processing. | 38.7% |
2930.20.20.10 |
Rubber Additive DBS (Powder) - Organic Compound | Classified as Thiocarbamates. Specific organic compound powder for rubber. | 16.5% |
3824.99.93.97 |
Rubber Additive DBS (Powder) - Other Chemical Product | Classified as Other Chemical Products. Material: Rubber additive. Form: Powder. | 40.0% |
🔍 Key Insight:
-2930.20.20.10offers the lowest tax rate (16.5%) but requires strict proof that the product is a specific "Thiocarbamate" organic compound, not just a mixture. -3824.99.29.00is the "catch-all" for chemical preparations, resulting in the highest tax rate (41.5%).
💰 III. 2026 Latest Tariff Rate Breakdown (Including Surtaxes)
✅ Applicable Country: United States (US)

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
