π‘οΈ PET Plastic Printed Circuit Board (PCB) Insulation Film
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: Do You Really Understand "PET Insulation Film"?
PET Plastic Insulation Film, primarily used in the manufacturing of Printed Circuit Boards (PCBs), is a critical raw material in the electronics supply chain. It is made from Polyethylene Terephthalate (PET), a thermoplastic polymer resin. In international trade, its classification depends heavily on whether it is treated as an electrical insulating tape/accessory (HS 3919/8547) or a general plastic film (HS 3920).
β οΈ Key Distinction Point:
- If the film is cut into strips, rolls, or sheets specifically designed for electrical insulation and is often categorized under electrical accessories or specialized tapes β Look at 8547 or 3919.
- If the film is a generic plastic sheet/film (even if intended for insulation) without specific electrical accessory shaping or branding β Look at 3920.
- Warning: Misclassification can lead to massive tariff differences (from 35% to nearly 90%).

π₯ βFilm is cheaper, Tape is mid, Fitting is king, Metal is death!β
| Situation | Correct Declaration | Wrong Action |
|---|---|---|
| Pure PET Film Rolls (No adhesive, used as insulation layer) | HS 8547.20.00.00 (Lowest Duty 35%) | Declare as "Plastic Sheet" (HS 3920, 39.2%) β Higher cost |
| Self-Adhesive PET Tape | HS 3919.10.20.20 (40.8%) | Declare as "Film" β Risk of misclassification |
| Product with Metal Coating | High Risk β Check for 50% surtax codes | Declare as pure PET β Customs rejection + fines |
| Generic Plastic Sheet | HS 3920.62.00.90 (39.2%) | Declare as "Electrical Accessory" β May be rejected if not specific |
π Key Strategy:
- If the product is not self-adhesive and is used as a layer in PCBs, argue for 8547.20.00.00 (Insulating Fittings) to save 4.2%~5.8% in base tariffs.
- If the product is self-adhesive, use 3919.10.20.20.
- If in doubt, 3920.62.00.90 is a safe, compliant middle ground.
β 3. Special Cases Handling
| Situation | Handling Advice |
|---|---|

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
