II.  Product:

The product covered by this investigation is commonly referred to as acrylonitrile butadiene rubber or nitrile rubber (“NBR”).

NBR is sold in bale, slab, crumb, powder, pellet, particulate, and liquid form. NBR in the latex form (HTSUS at subheading 4002.51.00) is excluded from the scope of this investigation. Also excluded from the scope of this investigation is: a) NBR containing additives (e.g. nitrile rubber further compounded with fillers, reinforcement agents, vulcanization agents, etc.; by example, products classified under HTSUS subheading 4005); b) NBR containing rubber processing chemicals, NBR containing other materials used for further processing beyond the polymerization process: and, (c) hydrogenated NBR (commonly referred to as HNBR) produced by subsequent dissolution and hydrogenation of NBR. The merchandise subject to this investigation is classified in the HTSUS at subheading 4002.59.00. Although the HTSUS subheading is provided for convenience and customs purposes, the written description of the merchandise under investigation is dispositive.

The general tariff (Column 1) assessed on imported goods entering the U.S. under HTSUS subheading 4002.59 is Free.
