AI Analysis
π§ͺ Anti-Static Flexible Polyester Film (PET) & Acrylic Materials
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Specialized Clearance Strategy
π I. Product Definition & Classification: What is "Anti-Static Flexible Film"?
Anti-static flexible films are high-performance plastic materials widely used in electronic manufacturing, packaging, and industrial applications to prevent electrostatic discharge (ESD) damage. Based on the material composition and physical form, they are primarily categorized into Polyester (PET) and Acrylic/Methyl Methacrylate (PMMA) types.
In international trade, precise classification depends on: 1. Base Material: Polyester (PET) vs. Methyl Methacrylate (PMMA/Acrylic). 2. Physical Form: Flexible film (thin sheets/rolls) vs. Rigid plates/sheets. 3. Functionality: General purpose vs. Specific functional coatings (e.g., anti-static).
β οΈ Key Classification Point:
- If the material is Polyester (PET) and used for electronic components, it typically falls under 3920.
- If the material is Methyl Methacrylate (PMMA/Acrylic) and described as flexible, it typically falls under 3921.90.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Match)
Based on the provided data, the following HS Codes are applicable. Note that duplicate HS Codes in the source data indicate different descriptive nuances but identical tariff treatments.
| HS Code | Product Description | Material | Form | Key Application / Classification Logic |
|---|---|---|---|---|
3920.62.00.50 |
Flexible Polyester Film for Electronic Components | Polyester (PET) | Flexible Film | Specifically for electronic components; fits under "Plastic Films". |
3921.90.40.90 |
Flexible Anti-Static Methyl Methacrylate Film | Methyl Methacrylate (Plastic) | Flexible Film | Fits under "Other Plastic Plates, Sheets, Film". |
3921.90.40.90 |
Flexible Anti-Static PMMA Film | PMMA (Plastic) | Flexible Film | Fully fits under "Plastic Flexible Materials"; PMMA is Methyl Methacrylate. |
3921.90.50.50 |
Flexible Anti-Static Methyl Methacrylate Film | Plastic (PMMA) | Film | "Other Plastic Plates, Sheets, Film"; inferred from material consistency. |
3921.90.50.50 |
Flexible Anti-Static Methyl Methacrylate Film | Plastic (PMMA) | Film | Same as above; based on material consistency inference. |
π Important Note:
-3920.62.00.50is specific to PET used in electronics.
-3921.90.40.90and3921.90.50.50are for PMMA/Acrylic materials.
- Although the HS Code prefixes (3920 vs 3921) differ, the Total Tax Rate is nearly identical due to shared supplementary tariffs.
π° III. 2026 Latest Tariff Rate Breakdown (Including Surcharges & Policy Add-ons)
β Applicable Country: United States (US)
β Country of Origin: China (CN)
β Effective Date: November 10, 2025 (and subsequent imports)
π― 1. 3920.62.00.50 β Flexible Polyester Film for Electronic Components
| Item | Content |
|---|---|
| Base Tariff | 4.2% |
| Section 301 Surcharge | +25.0% |
| 122 Clause Tariff | +10.0% |

- Still subject to the same 35% in surcharges.
π οΈ IV. Customs Clearance Practical Advice (Actionable Pitfall Avoidance)
β 1. Preparation Checklist (Non-Negotiable)
| Document | Required | Description |
|---|---|---|
| β Product Specification Sheet | βοΈ | Must specify: Material (PET/PMMA), Thickness, Width, Anti-Static Properties, and Intended Use (e.g., "Electronic Components"). |
| β Certificate of Analysis (COA) | βοΈ | Proves anti-static performance and chemical composition (Methyl Methacrylate vs. Polyester). |
| β Product Photos | βοΈ | Clear images of rolls, labels, and packaging. Must show "Anti-Static" branding if applicable. |
| β Commercial Invoice | βοΈ | Must accurately state "Flexible Anti-Static [Material] Film" and include HS Code. |
| β Packing List | βοΈ | Detail net/gross weight, dimensions, and number of rolls. |
| β Origin Certificate | βοΈ | To prove Chinese origin (triggering the specific tariffs above). |
β 2. Declaration Tips (Key Mnemonic)
π₯ "Material First, Form Second, Use Third!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| PET Film for Electronics | 3920.62.00.50 β "Flexible Polyester Film for Electronic Components" |
Vague terms like "Plastic Film" β Risk of audit |
| PMMA/Acrylic Flexible Film | 3921.90.40.90 or 3921.90.50.50 β "Flexible Methyl Methacrylate Anti-Static Film" |
Mislabeling as "Rigid Acrylic Sheet" β Wrong HS |
| General Purpose Plastic Film | Do not use these codes unless specific material/use matches | Over-specifying β Customs suspicion |
π Critical:
- If the film is rigid, it might fall under different subheadings. Ensure "Flexible" is clearly stated.
- If the film is not for electronic components,3920.62.00.50may be incorrect. Use3921series instead.
β 3. Special Handling Scenarios
| Scenario | Recommendation |
|---|---|
| Mixed Shipment (PET + PMMA) | Declare separately. Do not combine into one line item. Each has different HS codes. |
| Customs Audit on "Anti-Static" | Provide test reports showing surface resistance (e.g., $10^6 - 10^9$ ohms) to justify functional description. |
| Tariff Mitigation | Consider HTSUS Exclusions if eligible. Check if your specific manufacturer/product is on the US Trade Representative (USTR) exclusion list for Section 301 tariffs. |
| 122 Clause Impact | This 10% tariff is recent and aggressive. Ensure your broker is aware of the latest CBP interpretations. |
π V. Global Market Comparison (2026 Update)
| Country/Region | Recommended HS Code | Estimated Duty (Base) | Notes |
|---|---|---|---|
| πΊπΈ USA | 3920.62.00.50 / 3921.90.xxxx |
39.2% - 39.8% | High due to Section 301 + 122 Clause. |
| π¨π³ China | 3920.62.00.50 / 3921.90.xxxx |
~5% - 7% | Lower base rate, no Section 301. |
| πͺπΊ EU | 3920.53.00 / 3921.14.00 |
~5% - 6% | No Section 301 equivalent, but VAT applies. |
| π―π΅ Japan | 3920.62.00 / 3921.14.00 |
~6% - 8% | Stable, no major surcharges for these codes. |
π Conclusion:
- The US market is the most expensive for these imports due to layered tariffs.
- Accurate HS coding is critical to avoid overpayment or underpayment (which leads to penalties).
π VI. Common Errors & Pitfalls (Lessons Learned)
β Error 1: Describing PET film as "Plastic Sheet"
π Consequence: Misclassification to a higher-duty code or audit delay.
β
Fix: Use exact material name: "Polyester (PET)".
β Error 2: Ignoring the "122 Clause"
π Consequence: Unexpected 10% tariff increase on invoice.
β
Fix: Budget for total 39.2%+ tax from day one.
β Error 3: Confusing PET with PMMA
π Consequence: Wrong HS Code (3920 vs 3921). While tax rates are similar, compliance requires accuracy.
β
Fix: Verify Material Safety Data Sheet (MSDS) for chemical composition.
β Error 4: Vague "Electronic Component" Use
π Consequence: If not clearly for electronic components, 3920.62.00.50 may be rejected.
β
Fix: Provide end-use statement: "Used in manufacturing of capacitors/circuit boards."
π― VII. Conclusion: Precision Saves Money
π― Remember the Formula:
πΉ "PET for Electronics β 3920.62.00.50 (39.2%)"
πΉ "PMMA Flexible β 3921.90.40.90/50.50 (39.2%-39.8%)"
πΉ "Always Include: Section 301 (25%) + 122 Clause (10%)"
π Pro Tip:
If you are importing these materials into the US, apply for an HTSUS Exclusion if your product was originally on the exclusion list. This could save you up to 35% in duties.

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
