400251
Rubber; synthetic, acrylonitrile-butadiene rubber (NBR), latex, in primary forms or in plates, sheets or strip
Heading 4002 — Synthetic rubber and factice derived from oils, in primary forms or in plates, sheets or strip; mixtures of heading no. 4001 and 4002, in primary forms or in plates, sheets or strip
Chapter 40: Rubber and articles thereof
Plain-language overview
Use HS-6 400251 when importing or exporting synthetic acrylonitrile-butadiene rubber (NBR) in primary forms. This could include shipments of NBR latex in bulk containers or as sheets for manufacturing applications.
This code specifically covers NBR, a versatile synthetic rubber commonly used in automotive seals, gaskets, and hoses. It differs from HS-6 400252, which pertains to styrene-butadiene rubber (SBR), another synthetic rubber with distinct properties and applications.
When classifying products, it's important to note that HS-6 400251 applies to NBR in its primary form, while other forms or mixtures may fall under different codes. For example, if you have a mixture of NBR and natural rubber, you would need to consider HS-6 400299 instead.
Understanding the specific characteristics of your product, such as whether it's in sheets or liquid form, will help ensure accurate classification and compliance with customs regulations.
