Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If rigid but from other ethylene copolymers not meeting 95%
Subheading notes place copolymers below 95% ethylene in 'other' rigid categories like 3917.29.
If shaped as specialized fittings rather than straight tube
Complex plastic fittings (elbows/flanges) for valves classify under 8481 appliance parts.

The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Submit FTIR spectroscopy reports confirming ethylene polymer predominance
• Declare inner diameter and wall thickness to support rigid tubing status
