π‘οΈ Nylon Flat Round Plastic Washers (Gaskets/Seals)
π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Compliance Strategy
π I. Product Definition & Classification: What Exactly Are "Plastic Washers"?
Nylon flat round plastic washers are critical mechanical components used to distribute load, prevent leakage, and reduce friction between mating surfaces. In international trade, they are often confused with metal gaskets or general plastic parts. Precise classification depends on the material composition and specific function.
The key distinction lies in whether the product is a pure plastic seal (classified under Chapter 39) or a metal-composite seal (classified under Chapter 84). For "Nylon" (a plastic/polymer) washers, the primary classification falls under Chapter 39: Plastics and Articles Thereof.
β οΈ Critical Distinction Point:
- Pure Plastic/Nylon Washers: Made entirely of synthetic polymers β Go to 3926.90.45.10 / 3926.90.45.90.
- Metal-Combined Gaskets: If the washer has a metal core, mesh, or is layered with metal sheeting β Go to 8484.10.00.00.
- Sets/Assortments: Mix of dissimilar materials packed together β Go to 8484.90.00.00.
π¦ II. HS Code Classification Details (2026 Latest Tariff Authority Comparison)
Based on the provided <DATA>, here are the relevant HS Codes for Plastic Washers and related sealing components:
| HS Code | Product Description | Applicable Scenario | Material Composition |
|---|---|---|---|
3926.90.45.10 |
Gaskets, washers and other seals: O-Rings | Round nylon washers functioning as O-Rings or elastomeric seals | 100% Plastic (Nylon/Polymer) |
3926.90.45.90 |
Gaskets, washers and other seals: Other | Flat round nylon washers (non-O-ring type), gaskets, seals | 100% Plastic (Nylon/Polymer) |
8484.10.00.00 |
Gaskets of metal sheeting combined with other material | NOT APPLICABLE unless metal is present | Metal + Plastic/Composite |
8484.90.00.00 |
Gaskets sets/assortments (dissimilar composition) | Mixed kits (e.g., metal + plastic gaskets in one pack) | Mixed Materials |
3917.40.00.95 |
Plastic Fittings (Other) | Plastic pipe fittings (joints/elbows), not washers | 100% Plastic |
3917.29.00.90 |
Rigid Plastic Tubes/Hoses | Plastic pipes, not washers | 100% Plastic |
π Key Reminder:
- "Nylon" is a thermoplastic polymer. Therefore, pure nylon washers belong in Chapter 39, specifically under 3926.90.45 (Gaskets, washers, seals).
- Do NOT confuse them with 8484.10.00.00, which requires metal sheeting. Pure plastic washers do not qualify here.
- If the product is strictly an "O-Ring" shape, use3926.90.45.10. If it is a flat ring (washer) or irregular seal, use3926.90.45.90.

| β HS Code Pre-Ruling | β | Recommended if volume is high, to lock in the 0% rate. |
β 2. Declaration Tips (Key Mnemonics)
π₯ "Pure Nylon = 3926, Zero Tax! Metal Mixed = 8484, 27.5% Tax!"
| Scenario | Correct HS Code | Tax Rate | Common Mistake |
|---|---|---|---|
| Flat Nylon Washer | 3926.90.45.90 |
0.0% | Misclassifying as 8484.10.00.00 (27.5%) |
| Nylon O-Ring | 3926.90.45.10 |
0.0% | Using generic "Plastic Part" code |
| Washer with Metal Core | 8484.10.00.00 |
27.5% | Claiming it's plastic to save tax (Fraud Risk) |
| Plastic Pipe Fitting | 3917.40.00.95 |
0.0% | Confusing "Fitting" with "Washer" |

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
