4002.59.00.00 - Other

This HTS category, 4002.59.00.00, encompasses acrylonitrile-butadiene rubber (NBR) in all primary forms, plates, sheets, or strip, *except* for its latex form. This includes solid or semi-solid forms of NBR that have not been compounded or otherwise processed into finished articles. The primary characteristic defining this classification is the material itself – synthetic rubber produced through the copolymerization of acrylonitrile and butadiene – presented in a state suitable for further manufacturing.

This category specifically differentiates itself from its sibling, 4002.51.00.00 (Latex), by excluding the dispersed rubber particles suspended in an aqueous medium. While both fall under acrylonitrile-butadiene rubber, the physical form is the key distinguishing factor for classification at this level. Here, the NBR is not in a liquid, emulsion-based form.

As a leaf node, 4002.59.00.00 does not have further subcategories. Therefore, classification within this code is determined by the presence of acrylonitrile-butadiene rubber in a non-latex primary form, plate, sheet, or strip. Examples include bales, crudes, granules, or blocks of NBR, ready for molding, extrusion, or other manufacturing processes.
