HS Code for Unvulcanized rubber shapes

Unvulcanized rubber shapes are classified under HS code 4006.90 based on their material composition and physical form. This code falls under Heading 4006, which covers 'other' forms of unvulcanized rubber, such as rods, tubes, and profile shapes. The classification is determined by two primary factors: the rubber must be unvulcanized (meaning it has not undergone the chemical process of cross-linking with sulfur or other vulcanizing agents) and it must be in a form other than plates, sheets, or strips. These shapes are often intermediate products used in the manufacturing of seals, gaskets, and industrial components. The 'other' designation in 4006.90 specifically excludes 'camel-back' strips used for retreading tires, which are classified under 4006.10. The classification process requires a technical assessment of the rubber's state; if the rubber has been vulcanized, it would move to Heading 4008. This code is vital for manufacturers who import raw rubber profiles for further processing and final vulcanization in their own facilities.

Products Included

Common Misclassification

Unvulcanized rubber shapes are often confused with HS code 4005, which covers compounded rubber in primary forms like plates, sheets, or strips. If the material is in a simple flat form, it belongs in 4005, but if it has been extruded into a specific profile or shape, it moves to 4006.90. Additionally, confusion often arises with HS code 4008, which covers vulcanized rubber shapes. The presence of vulcanization (evidenced by elasticity and heat resistance) is the deciding factor between these two headings. Finally, 4006.10 must be avoided unless the product is specifically a camel-back strip for tire retreading.

FAQ

What is the HS code for unvulcanized rubber shapes?

The HS code for unvulcanized rubber shapes, other than camel-back strips, is 4006.90.

How do I tell if rubber is unvulcanized for classification?

Unvulcanized rubber is generally plastic and deformable, whereas vulcanized rubber is elastic and returns to its original shape after being stretched. Technical data sheets will specify the vulcanization state.
