π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Entry Strategy
π 1. Product Definition & Classification: What Exactly Are You Importing?
"Polyester Plastic Film" in this context refers to specific protective accessories. While they share the same raw material (Polyester/PE), their functional classification drastically changes their HS Code and tax liability. They are divided based on their specific role and form:
1. Protective Covers (General Accessories): Treated as general plastic parts/accessories.
2. Protective Caps/Lids (Specific Sealing Devices): Treated as specific plastic articles or plates/films depending on structure.
3. Protective Sheets (Bare Films): Treated as plastic plates/sheets/films without specific article functions.
β οΈ Key Differentiator:
- Is it a functional accessory for a machine/device? β3926.90series (General plastic articles).
- Is it a standalone sheet/film for wrapping/covering? β3921.90series (Plastic plates/sheets/films).
- Is it a cap/lid specifically for sealing? β3926.90(Other plastic articles) OR3921(If considered a sheet).

| Legal Authority Path | HTSUS:3926.90.48.00 β Section 122: 10% |
π Explanation:
- This code offers the lowest total tariff (13.4%).
- The key is proving the item is a "Protective Cover" (accessory/part) rather than a generic sheet or cap.

π― 2. 3926.90.99.89 ββ Polyester Plastic Sheet (Other Protective Accessories)
| Item | Content |

π Note:

- Still significantly cheaper than the sheet/film classifications.
π― 3. 3926.90.94.00 ββ Polyester Plastic Sheet (Protective Cap)
| Item | Content |
|---|---|
| Base Duty Rate | 0.0% |
| Section 301 Surcharge | +25.0% |
| Section 122 Surcharge | +10.0% |
| Total Tax Rate | 35.0% |

| De Minimis Eligibility | β No |
| Legal Authority Path | HTSUS:3926.90.94.00 β Section 301: 25% + Section 122: 10% |
π Warning:
- Even with 0% base duty, the 25% Sec 301 surcharge makes this expensive.
- Only use if the product is strictly a "Cap" (e.g., bottle cap, machine lid) and not a "Cover" (shield/protector).
π― 4. 3921.90.19.50 ββ Polyester Plastic Sheet (Plate/Sheet/Film)
| Item | Content |
|---|---|
| Base Duty Rate | 5.3% |

| Section 122 Surcharge | +10.0% |

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
