NBR Powder Granules
Granular form of acrylonitrile-butadiene rubber (NBR) produced by spray drying latex, used in compounding for seals and gaskets. Falls under HTS 4002.59.00.00 as synthetic rubber in primary bulk form (granules), per Chapter Note 3(c).

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If chemically modified (e.g., carboxylated NBR)
Note 3 excludes chemically transformed rubbers from headings 4001-4003.
If styrene-butadiene copolymer dominant
Material composition shifts to polymers of styrene if SBR rather than NBR.
If formed into regular plates/sheets
Chapter Note 8 defines plates/sheets as geometric blocks, separate from granules.

Import Tips & Compliance
• Ensure particle size and bulk form documentation to distinguish from finished articles
• Test for absence of cross-linking agents; presence disqualifies from primary form per Note 5
• Avoid bulk packaging that suggests 'articles' status, which shifts to heading 4008
