π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
π 1. Product Definition & Classification: What exactly is "Flexible Anti-Static PMMA"?
Methyl Methacrylate (MMA), commonly known as PMMA (Polymers of Methyl Methacrylate) or Acrylic, is a transparent thermoplastic. While typically rigid, it can be manufactured as a flexible film or thin sheet (<6mm) through specific stretching or compounding processes.
In international trade, this product is categorized based on its form (Film/Sheet) and material composition (Polymer). The "Anti-Static" feature is a functional additive, which generally does not change the primary classification unless it transforms the product into an electrical insulator with specific voltage ratings (rare for general films).
β οΈ Key Distinction:
- PMMA vs. PE/PET: Do not confuse with Polyethylene (PE) or Polyethylene Terephthalate (PET) films. PMMA has distinct density (~1.18 g/cmΒ³) and optical clarity.
- Flexible vs. Rigid: If thickness is β€ 6mm (common for films), it may fall under Chapter 39 (Plastics). If >6mm, it might be considered "plates/sheets" under Chapter 39 but potentially scrutinized differently. For "Film," we assume thin gauge.
- Anti-Static: This is a surface treatment or additive. It does not make it an "electrical machine" part. It remains a plastic article.
π¦ 2. HS Code Classification Details (2026 Latest Tariff Authority)
| HS Code | Product Description | Applicable Scenario | Key Features |
|---|---|---|---|
3920.62.00.00 |
Plates, sheets, film, foil and strip, of polymers of methyl methacrylate (PMMA), non-cellular, unworked or merely surface-worked | Primary Classification for PMMA films/sheets <6mm | β Raw PMMA material, transparent, flexible |
3920.99.90.90 |
Other plates, sheets, film, foil and strip, of plastics | If blended with other polymers or non-PMMA | β Only if not 100% PMMA |
3919.10.00.00 |
Self-adhesive plates, sheets, film, foil, tape, strip and other flat shapes, of plastics | If the anti-static film is backed with adhesive | β With glue layer |
3921.90.90.90 |
Other plates, sheets, film, foil and strip, of plastics | If cellular (foamed) or otherwise modified | β Not applicable for solid PMMA |
π Priority Selection:
-3920.62.00.00is the most accurate for non-cellular PMMA films/sheets.
-3919.10.00.00is used only if the film has an adhesive backing (e.g., protective film with glue).
-3920.99.90.90is a fallback if the material is not pure PMMA but a blend.π Critical Note:
- Thickness Matters: If the product is a rigid sheet (>6mm), it may still fall under3920.62.00.00but could be subject to different duties in some jurisdictions.
- "Anti-Static": This is a functional attribute, not a separate HS category. It is declared in the description but does not change the HS code.

π οΈ 4. Customs Clearance Practical Advice (Battle-Tested Pitfall Guide)
β 1. Documentation Checklist (Mandatory)
| Document | Required | Notes |
|---|---|---|
| β Product Specification | βοΈ | Must state: Material = 100% PMMA, Thickness (mm), Width, Anti-Static Property (Ξ©/sq) |
| β Certificate of Composition | βοΈ | Proving it is Methyl Methacrylate Polymer, not a blend with PVC/PE |
| β Technical Data Sheet | βοΈ | Showing optical clarity, flexibility, and anti-static level |
| β Commercial Invoice | βοΈ | Clearly describe as: "Flexible Anti-Static PMMA Film, Methyl Methacrylate Polymer" |
| β Packing List | βοΈ | Indicate if rolled or cut sheets |
| β Origin Certificate | βοΈ | Essential for proving CN origin to apply (or challenge) tariffs |
β 2. Declaration Tips (Key Mnemonics)
π₯ "Material First, Form Second, Additives Are Secondary!"
| Scenario | Correct Declaration | Wrong Practice |
|---|---|---|
| Pure PMMA Film, Non-Adhesive | 3920.62.00.00 β "PMMA Film" |
Misclassify as 3920.99 (Other Plastics) β Risk of penalty |
| PMMA Film with Adhesive | 3919.10.00.00 β "Self-Adhesive PMMA Film" |
Declare as non-adhesive β 5.7% vs 25%+10% on base, but risk of misdeclaration |
| Blended Polymer (e.g., PMMA/PE) | 3920.99.90.90 β "Other Plastic Film" |
Claim 100% PMMA β Customs lab test will fail, leading to seizure |
| Anti-Static Claim | Include in description | Use as HS code change β HS code does not change for additives |
β 3. Special Cases Handling
| Situation | Handling Advice |
|---|---|
| Flexible vs. Rigid | If thickness is >6mm, clarify in documents. It may still be 3920.62.00.00, but some ports may scrutinize as "sheet" vs "film". |
| Anti-Static Certification | Provide a lab report (e.g., ASTM D257) showing surface resistance <10^9 ohms. This proves functionality but does not lower duty. |
| OEM/Custom Orders | Provide client specs to prove it is a standard PMMA product with a surface treatment, not a "new invention" requiring different classification. |
| Mixed Containers | If mixed with PE films, declare separately. PMMA and PE have different HS codes and may have different origin rules. |

π 6. Common Mistakes & Pitfall Guide (Lessons Learned)
β Mistake 1: Classifying as 3920.99.90.90 (Other Plastics) to avoid scrutiny
π Consequence: If lab tests show 100% PMMA, customs will reclassify and apply correct HS code + penalties.
β Mistake 2: Ignoring the "Self-Adhesive" feature
π Consequence: If the film has glue, declaring it as non-adhesive (3920) is misdeclaration. Correct code is 3919.10.00.00.
β Mistake 3: Assuming "Anti-Static" lowers tariffs
π Consequence: Tariffs are based on material, not function. No reduction.
β Mistake 4: Not specifying thickness
π Consequence: Ambiguity leads to customs hold for lab testing, causing delays.
β Correct Practice:
"Flexible Anti-Static Film, 100% Polymers of Methyl Methacrylate (PMMA), Thickness 0.5mm, Width 1.2m, Surface Resistance 10^8 Ohms/sq, Non-Adhesive, Model XYZ, REACH Compliant"
π― 7. Conclusion: Precise Classification Saves Money!
π― Remember the Mnemonic:
πΉ "PMMA is 3920.62, Adhesive is 3919.10, Anti-Static Doesn't Change Code!"
πΉ "USA Tariffs are High (~40%), Consider Non-CN Origin for US Market!"
π Pro Tip:
If your PMMA film is originating from Vietnam, Malaysia, or Thailand, you may qualify for 0%~5% tariffs in the US under USMCA or GSP rules.
Recommendation: Apply for Pre-Ruling (Advance Ruling) from US Customs to confirm classification and tariff liability.

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
