π§ͺ SBR Solution for Adhesive Applications (Styrene-Butadiene Rubber)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π 1. Product Definition & Classification: What Exactly is "SBR Solution"?
SBR Solution for Adhesive Applications refers to Styrene-Butadiene Rubber produced via solution polymerization, specifically formulated or designated for use in adhesives. In international trade, this material sits at a crossroads between raw rubber materials and prepared adhesives.
The classification depends heavily on whether the product is declared as: 1. Raw Material (Unprepared Rubber): The SBR latex or solid rubber concentrate before final adhesive formulation. 2. Prepared Adhesive: The SBR already mixed with solvents, resins, or additives to form a ready-to-use adhesive or a specific adhesive base.
β οΈ Key Distinction Point:
- If it is pure SBR rubber (latex or solid) intended for adhesive manufacturing β It is a Rubber Product (Chapter 40).
- If it is SBR mixed with solvents/additives to be used as an adhesive β It is a Prepared Adhesive (Chapter 35).
π¦ 2. HS Code Classification Details (2026 Latest Tariff Authorityε―Ήη §)
Based on the provided data, there are four primary HS Codes applicable, split between Raw Rubber and Prepared Adhesives.
| HS Code | Product Description | Category | Tax Rate | Basis for Classification |
|---|---|---|---|---|
4002.19.00.16 |
Solution Polymerized SBR for Adhesive Use | Raw Rubber | 35.0% | Material is Styrene-Butadiene Rubber. Form is solution-polymerized. Used for adhesives but classified as the raw polymer material. |
3913.90.10.00 |
SBR (Chemical Derivative of Natural Rubber) for Adhesive Use | Raw Rubber | 35.0% | Material is SBR. Form is solution-method. Classified under chemical derivatives of natural rubber for adhesive applications. |
3506.91.50.00 |
Prepared Adhesive Containing SBR Solution | Prepared Adhesive | 37.1% | Material contains SBR but is defined as a "prepared adhesive" (mixture). Meets polymer/rubber requirements for adhesive formulation. |
3506.99.00.00 |
SBR Solution Used as Adhesive | Prepared Adhesive | 37.1% | Defined as "Other prepared adhesives." SBR solution is the base, but the product is functionally an adhesive. |
π Critical Note:
- HS 4002/3913 (Raw Rubber): Lower tax rate (35%). Choose if you are importing the pure rubber polymer to manufacture adhesives later.
- HS 3506 (Prepared Adhesive): Higher tax rate (37.1%). Choose if you are importing a mixture that is already ready for adhesive use.
- Misclassification Risk: Declaring a pre-mixed adhesive as raw rubber (3506 vs 4002) can lead to audits and penalties.

| β Certificate of Origin | βοΈ | To confirm China origin for surcharge application. |
| β Production Process Description | βοΈ | Explain if the product is "Unprepared" or "Prepared." |
β 2. Declaration Strategy (Key Mantra)
π₯ "Raw Rubber = Chapter 40/39 (35%); Prepared Adhesive = Chapter 35 (37.1%)! Misclassification = Penalty!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Importing pure SBR latex/solids to mix later | 4002.19.00.16 or 3913.90.10.00 |
Declaring as "Adhesive" β Higher tax |
| Importing SBR mixed with solvents for direct use | 3506.91.50.00 or 3506.99.00.00 |
Declaring as "Raw Rubber" β Audit risk |
| SBR in Solution (Solvent + Rubber) | Check Formula: If only solvent+rubber, may be Chapter 35. | Assuming all "solution" products are Chapter 40 |
β 3. Special Cases Handling
| Case | Handling Advice |
|---|---|
| OEM Custom Adhesive | Provide customer formula + design specs. Avoid generic "Adhesive" names; use specific chemical names. |
| SBR Latex vs. Solid Rubber | Latex is often 4002.19. Solid rubber may be 4002.51 or 3913.90. Confirm physical state. |
| Duty Drawback | If imported as Raw Rubber (35%) and later exported as finished goods, potential for duty drawback exists. |
| Section 301 Exemption | No general exemption for SBR from China. Check for specific UFLPA compliance if supply chain is complex. |

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
