HS-4 · Heading
3812 — Prepared rubber accelerators; compound plasticisers for rubber or plastics, n.e.c. or included; anti-oxidising preparations and other compound stabilisers for rubber or plastics
Chapter 38: Miscellaneous chemical products
Plain-language overview
Use HS-4 3812 when importing prepared rubber accelerators, plasticisers for rubber or plastics, or anti-oxidising preparations. For example, if you're shipping a batch of rubber accelerators used in tire manufacturing, this heading applies directly.
When deciding between HS-6 381210 and HS-6 381220, consider the product's function. If your shipment consists of a specific rubber accelerator like diphenylguanidine, go with 381210. If your product is a compound plasticiser like dioctyl phthalate, then 381220 is the correct choice.
For anti-oxidising preparations, choose between HS-6 381231 and HS-6 381239 based on the composition. If your product includes oligomers of 2,2,4-trimethyl-1,2-dihydroquinoline (TMQ), use 381231. For other stabilisers that do not contain TMQ mixtures, select 381239.
