HS Code for Polyethylene pipe

Polyethylene pipes are classified under HS code 3917.21, which is designated for rigid tubes, pipes, and hoses made of polymers of ethylene. This classification is governed by the General Interpretative Rules (GIR) and the specific definitions provided in Chapter 39 of the Harmonized System. Heading 3917 covers all plastic piping, but the sub-classification 3917.21 is reserved for products that are "rigid." In the context of customs classification, a pipe is considered rigid if it cannot be bent by hand at room temperature (15 to 30 degrees Celsius) without breaking or becoming permanently deformed. Most High-Density Polyethylene (HDPE) pipes used in water mains, gas distribution, and industrial drainage meet this definition. The classification process involves verifying that the primary constituent material is a polymer of ethylene and that the product is a finished tube or pipe intended for the conveyance of gases or liquids.

Products Included

• HDPE (High-Density Polyethylene) water pipes
• Rigid PE gas distribution pipes
• Polyethylene conduit for electrical cables
• Rigid irrigation pipes made of ethylene polymers
• PE-RT (Polyethylene of Raised Temperature) rigid pipes

Common Misclassification

Polyethylene pipes are often misclassified under 3917.32 or 3917.39. Code 3917.32 refers to flexible tubes and pipes that are not reinforced and do not have fittings. If a PE pipe is flexible enough to be coiled and bent by hand without damage, it may move from 3917.21 to the flexible categories. Another common error is using 3917.40, which is reserved for pipe fittings (like elbows and flanges) rather than the pipes themselves.

FAQ

What is the HS code for polyethylene pipe?

The standard HS code for rigid polyethylene pipe is 3917.21.

Does this code include flexible PE tubing?

No, flexible PE tubing is generally classified under 3917.32 if it is not reinforced, as 3917.21 is strictly for rigid structures.
