HS Code for NBR latex

NBR latex is classified under HS code 4002.51 because it is a synthetic rubber consisting of an acrylonitrile-butadiene copolymer in an aqueous dispersion. According to the Harmonized System's Chapter 40, synthetic rubber is defined as unsaturated synthetic substances which can be irreversibly transformed by vulcanization into non-thermoplastic substances. The specific subheading 4002.51 is reserved for NBR in its latex form. This classification is determined by the physical state of the product at the time of import. Latex is characterized by its liquid, milky appearance, consisting of polymer particles suspended in water. The classification follows General Rule of Interpretation (GRI) 1, which dictates that classification is determined by the terms of the headings and any relative section or chapter notes. Since the product is an acrylonitrile-butadiene rubber and is presented as a latex, it fits precisely into this category. This material is widely used in the production of dipped goods, such as medical and industrial gloves, where the liquid form allows for easy processing through coagulation dipping. The high acrylonitrile content in the latex provides excellent resistance to oils and chemicals, which is a defining characteristic of NBR products.

Products Included

• Liquid NBR latex
• Carboxylated NBR latex (XNBR)
• Nitrile latex for medical glove manufacturing
• NBR dispersions for textile coating

Common Misclassification

NBR latex is frequently confused with HS code 4002.59, which covers NBR in solid forms like bales or powders. It may also be misclassified under 4001.10 if the customs agent mistakes the synthetic nitrile for natural rubber latex. Additionally, if the latex is pre-vulcanized or mixed with other polymers, some may incorrectly attempt to classify it under 4005.

FAQ

What is the HS code for NBR latex?

The HS code for NBR latex is 4002.51, which specifically covers acrylonitrile-butadiene rubber in latex form.

How does NBR latex differ from NBR rubber in HS classification?

The primary difference is the physical state; 4002.51 is for liquid dispersions (latex), while 4002.59 is for solid primary forms like blocks, crumbs, or sheets.
