HS Code for Unvulcanized rubber solutions

Unvulcanized rubber solutions and dispersions are classified under HS code 4005.20. This code is situated within heading 4005, which covers compounded, unvulcanized rubber. Unlike the solid forms (blocks or sheets), 4005.20 is reserved for rubber that has been dissolved in a solvent or dispersed in a liquid medium. These solutions are frequently used as industrial coatings, sealants, or as a base for manufacturing adhesives. The classification requires that the rubber be compounded with other substances before being liquefied. It is important to distinguish these from natural rubber latex (Chapter 4001) or simple solutions of uncompounded rubber. The presence of compounding ingredients like vulcanizing agents or plasticizers within the liquid medium is the primary reason for classification under 4005.20. The product is usually liquid or paste-like in consistency and is intended to be applied to a surface where the solvent evaporates, leaving a layer of unvulcanized rubber.

Products Included

• Compounded rubber solutions in organic solvents
• Unvulcanized rubber dispersions in water
• Rubber-based liquid sealants (unvulcanized)
• Compounded rubber pastes
• Liquid rubber compounds for dipping processes

Common Misclassification

This code is often confused with HS code 4005.10 if the solution contains carbon black or silica; however, 4005.20 is generally the specific code for solutions regardless of fillers in many jurisdictions, though 4005.10 can take precedence if reinforcing agents are present. It is also confused with HS code 3506 (prepared glues and adhesives). If the product is specifically formulated and sold as an adhesive, 3506 is more appropriate.

FAQ

What is the HS code for Unvulcanized rubber solutions?

The HS code for unvulcanized rubber solutions and dispersions is 4005.20.

Is rubber cement classified under this code?
