HS Code for Chloroprene rubber

Chloroprene rubber, widely known by the trade name Neoprene, is a synthetic polymer produced by the polymerization of chloroprene (2-chlorobuta-1,3-diene). It is classified under HS code 4002.49. Chapter 40 of the Harmonized System covers rubber and articles thereof. Heading 4002 specifically addresses synthetic rubber and factice derived from oils, in primary forms or in plates, sheets, or strip. To qualify for this classification, the material must meet the definition of "synthetic rubber" in Note 4 to Chapter 40: it must be an unsaturated synthetic substance that can be irreversibly transformed by vulcanization with sulphur into a non-thermoplastic substance. Subheading 4002.49 is the residual category for chloroprene rubber in solid forms, such as chips, slabs, or blocks, distinguishing it from the latex form. This classification is essential for manufacturers in the automotive, construction, and diving suit industries who import raw neoprene for further processing.

Products Included

• Solid chloroprene rubber (CR) in blocks, lumps, or similar primary forms
• Neoprene chips or granules for industrial compounding
• Unvulcanized chloroprene rubber plates, sheets, or strips
• Non-latex synthetic chloroprene elastomers

Common Misclassification

Chloroprene rubber is often confused with HS code 4002.41, which is specifically for the latex form. It may also be misclassified under 4005.10 if it has been compounded with carbon black or silica before import. Furthermore, finished articles made of neoprene, such as wetsuits, are classified in Chapter 61 or 62, not under the raw material code 4002.49.

FAQ

What is the HS code for chloroprene rubber?

The HS code for chloroprene rubber (CR) in primary forms or solid sheets is 4002.49.

Does 4002.49 include vulcanized neoprene?

No, HS code 4002.49 only covers unvulcanized synthetic rubber. Once the rubber is vulcanized, it is classified under other headings in Chapter 40, such as 4008 for plates and sheets.
