HS Code for Plastic pipe fitting

HS code 3917.40 covers fittings for tubes, pipes, and hoses made of plastic. These components are classified based on their function within a piping system, which includes joining lengths of pipe, changing the direction of flow, or adapting different pipe sizes. Under the Harmonized System, heading 3917 is divided between the actual tubes/pipes and the fittings used to connect them. Classification under 3917.40 requires the item to be made of plastic and designed specifically for use with the types of pipes described in the earlier subheadings of 3917. This includes fittings for both rigid and flexible piping systems. The technical specifications, such as pressure ratings or the specific type of polymer (PVC, PE, or PP), do not change the primary four-digit heading but are essential for determining the correct six-digit subheading in international trade.

Products Included

• Plastic pipe elbows and tees
• Plastic couplings and unions
• Plastic flanges for piping systems
• Plastic bushings and reducers
• Plastic end caps for sealing pipe terminations

Common Misclassification

A common error is classifying plastic valves under 3917.40. Valves, even if made of plastic and used in piping, must be classified under HS code 8481.80. Furthermore, fittings made of reinforced plastic or those combined with metal threads are sometimes incorrectly placed in Chapter 73 (iron or steel) if the metal component is deemed to provide the essential character, though most plastic-bodied fittings remain in 3917.40.
