π οΈ VAC Copolymer Resin for Pipes (Acrylic Vinyl Copolymer Resin Pipes)
π HS Code Classification & Duty Guide | 2026 Updated Tariff Analysis | Expert Customs Clearance Strategy
π One Product, Five HS Codes β Know Which One Applies to Your Shipment!
π¦ 1. Product Definition & Key Classification Criteria
VAC Copolymer Resin Pipes are rigid plastic pipes made from vinyl acetate copolymer (VAC) resin β a thermoplastic material combining ethylene and vinyl acetate monomers. These pipes are used in industrial, plumbing, and chemical transport applications due to their corrosion resistance, flexibility, and durability.
β οΈ Critical Distinction: - If the pipe is rigid, pre-formed, and used as a conduit β Classified under plastic pipes (HS 3917.29.00.x0) - If the pipe is not pre-formed, or used as a general plastic product β May fall under other plastic articles (HS 3926.90.99.89) - If the resin itself is the primary form (e.g., granules, pellets) β May be classified under resins (HS 3905.21/29.00.00)
π Key Determinants: - Physical form: Hard pipe vs. raw resin vs. other plastic products
- Function: Conduit for fluids vs. general plastic item
- Structure: Pre-formed, molded, or extruded pipe

3917.29.00.50 |
VAC copolymer resin pipe, form: pipe or tubing, fits plastic pipe definition | Matches plastic pipe subheading 3917.29.00 | 38.1% |
3926.90.99.89 |
VAC copolymer resin pipe, classified as "other plastic articles", no conflict with material | Broad category for non-specific plastic items | 22.8% |
3905.29.00.00 |
VAC copolymer resin pipe, VAC = vinyl acetate copolymer, matches original form | Matches resin category with copolymer structure | 39.0% |
3905.21.00.00 |
VAC copolymer resin pipe, VAC = vinyl acetate copolymer, fits original form classification | Matches resin category, no functional conflict | 39.0% |
β All five codes are valid β the correct one depends on physical form, structure, and intended use.

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
