π§ͺ Polyester UV Absorber Raw Material
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy π I. Product Definition: What is "Polyester UV Absorber Raw Material"?
This product represents a specialized chemical intermediate. It is not a simple polyester resin nor a simple UV absorber, but a composite raw material often used in coatings, plastics, and fibers to provide UV resistance while maintaining the structural properties of polyester.
In international trade, its classification hinges on two key attributes: 1. Chemical Composition: It contains Polyester Resin (a chemical polymer). 2. Functional Additive: It contains UV Absorbers (chemicalεΆε/preparations).
Depending on the manufacturing process and the dominant component, it can be classified into four distinct HS Codes under the current US Tariff Schedule (2026).

π οΈ IV. Customs Clearance Practical Advice (Avoid Pitfalls)
β 1. Documentation Checklist (Non-Negotiable)
| Document | Must Provide | Purpose |
|---|---|---|
| β Technical Data Sheet (TDS) | βοΈ | Must show % composition of Polyester vs. UV Absorber. |
| β Certificate of Analysis (COA) | βοΈ | Proves chemical structure (Unsaturated vs. Saturated). |
| β Product Photos | βοΈ | Show form: Pellets, Powder, or Liquid. |
| β Commercial Invoice | βοΈ | Must clearly state "Polyester Resin with UV Absorber" or "Chemical Preparation". |
| β Origin Certificate (CO) | βοΈ | To confirm China origin for Section 301/122 application. |
β 2. Classification Strategy (Key Tips)
π₯ "Resin First, Additive Second: If itβs Resin, use 3907. If itβs Mix, use 3824."
| Scenario | Recommended HS Code | Reason |
|---|---|---|
| High UV Absorber Content (>10%) | 3824.99.29.00 |
Treated as a chemical preparation/mixture. |
| Low UV Absorber, Unsaturated Resin | 3907.91.20.00 |
Treated as Unsaturated Polyester. Lowest Tax (35%). |
| Low UV Absorber, Primary Shape | 3907.91.40.00 |
Treated as Polyester Resin. |
| Generic Chemical Additive | 3824.40.50.00 |
If marketed specifically as a UV-blocking additive for polyester. |
β 3. Special Considerations
| Situation | Advice |
|---|---|
| OEM Custom Blend | Provide formula sheets. If UV absorber is <5%, argue for 3907 classification. |
| Liquid vs. Solid | Liquid may be harder to classify as "Primary Shape" (3907.91.40). Prefer 3824 or 3907.91.20. |
| Pre-Mixed vs. Blended at Import | Pre-mixed = One HS Code. Blended at import = Two HS Codes (Higher risk, complex clearance). |
π V. Global Market Comparison (2026)
| Country/Region | Recommended HS Code | Tariff (China Origin) | Notes |
|---|---|---|---|
| πΊπΈ USA | 3907.91.20.00 |
35.0% | Best Rate. Requires strong resin argument. |

0% - 6.5% | REACH registration required. |
| π―π΅ Japan | 3907.91.20.00 |
0% - 5% | Shinryo (Chemical) report required. |
π Conclusion: - USA is the most challenging market due to Section 301 (25%) + Section 122 (10%). - Strategic Choice: Aim for
3907.91.20.00to achieve the lowest effective rate of 35%. - Avoid3824.99.29.00unless technically unavoidable, as it carries the highest rate (41.5%).
π VI. Common Mistakes & Pitfalls (Lessons Learned)
β Mistake 1: Classifying as 3902.10 (Polypropylene) by mistake.
π Consequence: Wrong classification, penalties, and delayed clearance. Polyester β Polyolefin.
β Mistake 2: Ignoring Section 122 Tariff.
π Consequence: Underpayment. Section 122 adds 10% on top of Section 301 for many chemicals.
β Mistake 3: Claiming "De Minimis" for small shipments.
π Consequence: Denied. Chemicals under Section 301/122 are not eligible for $800 de minimis exemption if origin is China.
β Mistake 4: Vague Description ("Resin Additive").
π Consequence: Customs may reclassify to 3824.99.29.00 (41.5%) due to uncertainty.
β Correct Practice:
"Unsaturated Polyester Resin with UV Absorber, Primary Shape, Model XYZ, CAS No. XXXXX-XX-X"
π― VII. Conclusion: Professional Clearance, Cost Optimization!
π― Remember:
πΉ "If itβs Resin, use 3907. If itβs Mix, use 3824."
πΉ "Target 3907.91.20.00 for 35% Tax. Avoid 3824.99.29.00 at 41.5%."
πΉ "Section 301 (25%) + Section 122 (10%) is Mandatory for China Origin."
π Pro Tip:
If your product is OEM blended with <5% UV absorber, argue for 3907.91.20.00 with a COA proving resin dominance. This can save 6.5% in tariffs.

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
