HS Code for Rubber tubing with fittings

The classification of rubber tubing with fittings under HS code 400912 is determined by the material, the lack of reinforcement, and the presence of attachments. Heading 4009 covers tubes, pipes, and hoses of vulcanized rubber other than hard rubber. The heading is structured based on whether the rubber is reinforced or combined with other materials (such as metal or textile) and whether the tubing is equipped with fittings. Subheading 400912 specifically refers to tubing that is not reinforced or otherwise combined with other materials but is presented with fittings. Fittings include items like joints, elbows, flanges, or couplings that allow the tubing to be connected to other pipes or machinery. The rubber must be vulcanized to fall under this heading; unvulcanized rubber tubing is classified under 4006. The "not reinforced" criteria means the wall of the tube consists entirely of vulcanized rubber without any internal or external layers of wire, fabric, or other strengthening materials. This type of tubing is common in low-pressure applications where the inherent strength of the rubber is sufficient. Classification follows GRI 1 and 6, focusing on the specific physical characteristics described in the subheading text. If the tubing were to have any form of reinforcement, it would immediately move to subheadings 400922, 400932, or 400942, depending on the type of reinforcement used.

Products Included

• Vulcanized rubber hoses with attached metal couplings
• Non-reinforced rubber tubes with plastic connectors
• Flexible rubber piping with flanges for fluid transfer
• Unreinforced synthetic rubber tubing with end-fittings
• Rubber drain hoses with integrated attachment points

Common Misclassification

The most frequent misclassification occurs with 400911, which is for tubing without fittings. Importers often overlook the presence of connectors or clamps that qualify as fittings. Another error is misclassifying reinforced tubing under 400912; if the rubber contains a textile braid or metal wire, it must be classified under 400922 (metal) or 400932 (textile). Additionally, tubing made of "hard rubber" (ebonite) is excluded from 4009 and falls under 401700.

FAQ

What is the HS code for Rubber tubing with fittings?

The HS code for vulcanized rubber tubing that is not reinforced but has fittings is 400912.

What counts as a fitting for this HS code?

Fittings include any device attached to the end of the tube to facilitate connection, such as bolts, flanges, unions, or specialized couplings.
