Heading 4005 — Compounded rubber, unvulcanised, in primary forms or in plates, sheets or strip
Chapter 40: Rubber and articles thereof
Plain-language overview
Use HS-6 400599 when importing or exporting compounded rubber that is unvulcanised and not mixed with carbon black or silica, such as rubber in blocks or granules. For instance, if you are shipping a batch of compounded rubber pellets intended for further processing, this code applies.
This code specifically covers unvulcanised rubber in primary forms, distinguishing it from HS-6 4005XX, which includes rubber in plates, sheets, or strips. If your product is in a solid block or granule form, rather than a sheet, you should use 400599.
When classifying compounded rubber, consider whether it contains carbon black or silica. If it does, you would look at other codes under the same heading. However, if your product is purely compounded without these additives, 400599 is the correct choice.
