What types of products are classified under HS-4 3917?

HS-4 3917 includes tubes, pipes, hoses, and fittings made from plastics, such as PVC and polypropylene.

How do I choose between the subheadings under HS-4 3917?

Select the subheading based on the material type and whether the product is rigid or flexible, as well as if it includes fittings.

Are artificial sausage casings included in HS-4 3917?

Yes, artificial sausage casings made from hardened protein or cellulosic materials are classified under **391710**.

What is the difference between HS-6 391731 and 391732?

HS-6 391731 is for flexible tubes with a minimum burst pressure of 27.6MPa, while 391732 is for other flexible tubes without that pressure requirement.

Can I classify all plastic pipes under the same HS code?

No, you need to classify them based on the specific polymer used, such as ethylene, propylene, or vinyl chloride.

What should I do if my product doesn't fit any specific subheading?

If your product doesn't match the specific subheadings, check **391729** for other rigid plastics or consult with a customs broker for guidance.

HS-4 3917: Tubes, pipes and hoses and fittings thereof (for example, joints, elbows, flanges), of plastics

Plain-language overview

Use HS-4 3917 when importing tubes, pipes, hoses, or fittings made from plastics, such as a shipment of PVC pipes for construction. This heading covers both rigid and flexible types, as well as various fittings like elbows and flanges.

When deciding between subheadings, consider the material composition. For instance, 391721 is specifically for rigid tubes made from ethylene polymers, while 391722 is for those made from propylene. If your product doesn’t fit these specific polymers, check 391729 for other rigid plastics.

Flexible tubes with a minimum burst pressure of 27.6MPa fall under 391731. If your flexible hoses do not meet this pressure requirement or are not reinforced, you may need to classify them under 391732 or 391733, depending on whether they come with fittings.

Fittings, such as joints and flanges, are classified under 391740. If your shipment includes fittings but no tubes or hoses, this is the appropriate subheading.
