HS Code for Acrylonitrile-butadiene rubber latex

Acrylonitrile-butadiene rubber (NBR) in latex form is classified under HS code 4002.51. Like the solid form, it falls under Chapter 40 (Rubber) and Heading 4002 (Synthetic rubber). However, the Harmonized System distinguishes between the physical states of synthetic rubber. Subheading 4002.51 is specifically for NBR latex. Latex is defined as a colloidal dispersion of rubber particles in an aqueous medium. This classification is straightforward based on the physical state of the NBR at the time of import. The latex must be in its primary form, meaning it has not been further worked or compounded into finished articles. This classification follows General Interpretative Rule 1, as the subheading text explicitly mentions 'latex.' It is essential for manufacturers of dipped goods, such as nitrile gloves, who import the raw liquid material for their production lines.

Products Included

• NBR latex (liquid dispersion)
• Nitrile rubber latex
• Acrylonitrile-butadiene aqueous dispersions
• Pre-vulcanized NBR latex
• Carboxylated NBR latex (XNBR)

Common Misclassification

The most common misclassification is using HS code 4002.59, which is reserved for NBR in solid primary forms like blocks or crumbs. Importers may also mistakenly use 4001.10, which is for natural rubber latex; NBR is synthetic and must stay within heading 4002. If the latex has been processed into a finished product, such as a medical glove, it must be classified under 4015.19 rather than the raw material code.

FAQ

What is the HS code for NBR latex?

The specific HS code for acrylonitrile-butadiene rubber in its latex form is 4002.51.

Can NBR latex be pre-vulcanized?

Yes, pre-vulcanized synthetic rubber latex remains classified under 4002.51 as long as it remains in the form of a colloidal dispersion in an aqueous medium.
