HS Code for Unvulcanized rubber profiles

Unvulcanized rubber profiles are classified under HS code 4006.90. This heading covers "other forms" of unvulcanized rubber, including rods, tubes, and profile shapes. While heading 4005 covers rubber in primary forms or sheets, heading 4006 is reserved for rubber that has been worked into specific shapes but has not yet been vulcanized. The subheading 4006.90 is the "other" category, excluding "camel-back" strips used for retreading tires (which fall under 4006.10). These profiles are typically intermediate products used in manufacturing processes where the final shape is formed before the rubber is cured or heated. The classification relies on the fact that the rubber is compounded and shaped but lacks the cross-linking of polymer chains that characterizes vulcanized rubber. These shapes are often extruded and may be used for seals, gaskets, or weatherstripping before they undergo the final curing stage.

Products Included

• Extruded unvulcanized rubber rods
• Unvulcanized rubber tubes and pipes
• Custom profile shapes of unvulcanized rubber
• Unvulcanized rubber discs and rings
• Intermediate rubber shapes for industrial manufacturing

Common Misclassification

A common misclassification occurs with HS code 4008, which covers plates, sheets, strips, rods, and profile shapes of vulcanized rubber. The critical distinction is the state of vulcanization; if the rubber has been cured, it must be classified under 4008. Another error is using 4006.10, which is strictly for "camel-back" strips for tire retreading. General profiles must stay in 4006.90.

FAQ

What is the HS code for Unvulcanized rubber profiles?

The HS code for unvulcanized rubber profiles, rods, and tubes is 4006.90.

Can unvulcanized tubes be classified here?

Yes, unvulcanized rubber tubes are classified under 4006.90 as they are considered a "form" of unvulcanized rubber other than primary forms or sheets.
