π HS Code Reference & Customs Clearance Guide | 2026 Latest Tariff Analysis | Professional Clearance Strategy
π I. Product Definition & Classification: Do You Really Understand "Metal Reinforced Plastic Tubes"?
Metal Reinforced Plastic Tubes are composite piping systems where the structural integrity is provided by a metal mesh or skeleton, while the inner and outer layers consist of plastic (typically PE-RT, PEX, or similar polymers). In international trade, they are primarily classified under Chapter 39 (Plastics and Articles Thereof), specifically as "Plastics Articles" rather than iron or steel articles, because the plastic layer defines the primary function and contact surface with the fluid.
Key Classification Logic:
- Core Material: Plastic (determines Chapter 39).
- Reinforcement: Metal mesh/wire (does not change the primary character if plastic is dominant).
- Form: Pipes/Tubes (Heading 3917).
- Usage: Cold water, drainage, DWV (Drain-Waste-Vent), or general plumbing.
β οΈ Critical Distinction:
- If the tube is specifically for Drain/Waste/Vent (DWV) or general Drainage, it often falls under 3917.39 or 3917.40.
- If it is strictly for Water Supply (pressurized cold water), it may fall under 3917.23 (PE pipes) or 3917.39 depending on the specific plastic composition and pressure rating.
- Note: The provided DATA suggests classifications under 3917.39, 3926.90, and 3917.40, indicating a focus on drainage/plastic pipe assemblies.
π¦ II. HS Code Classification Details (Based on Provided DATA)
| HS Code | Product Description | Summary from DATA | Tax Rate (Total) | Tax Details |
|---|---|---|---|---|
| 3917.39.00.10 | Plastic Pipes & Tubes, Other | Core material is plastic, form is tube, fits plastic tube classification. | 38.1% | Base: 3.1%, Section 301: 25.0%, Section 122: 10% |
| 3926.90.99.40 | Other Plastic Articles | Core material is plastic, categorized as drainage plastic product, no material conflict. | 22.8% | Base: 5.3%, Section 301: 7.5%, Section 122: 10% |
| 3917.40.00.50 | Plastic Pipes & Tubes, Valves & Fittings | Core material is plastic, usage is DWV (Drain, Waste, Vent), fits classification requirements. | 40.3% | Base: 5.3%, Section 301: 25.0%, Section 122: 10% |
π Important Note:
- 3917.39 and 3917.40 are the most accurate for pipes/tubes.
- 3926.90 is generally for other plastic articles and might be used if the product is considered a "component" or "assembly" rather than a standard pipe, but this is less common for straight tubes. It offers a significantly lower tariff in this dataset.

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
