HS Code 4002.51 – Rubber; synthetic, acrylonitrile-butadiene rubber (NBR), latex, in primary forms or in plates, sheets or strip
HS code 4002.51 is the 6-digit subheading for rubber, synthetic, acrylonitrile-butadiene rubber (NBR), latex, in primary forms or in plates, sheets or strip. It is used for NBR latex concentrate, nitrile latex, NBR emulsion, NBR glove dipping compound and NBR coating base.
What HS 4002.51 covers
This HS code covers acrylonitrile-butadiene rubber (NBR) in latex form, traded as a liquid emulsion. NBR latex is a specialized synthetic rubber primarily valued for its excellent oil, fuel, and chemical resistance, along with good abrasion properties. It is a key raw material for manufacturers of disposable gloves, coatings, and adhesives, particularly where contact with oils or solvents is expected. Chemical companies export NBR latex to medical, automotive, and industrial sectors globally. The trade is driven by the critical need for protective barriers and durable coatings in demanding environments, especially for medical and industrial safety applications. Understanding its specific handling and storage as a liquid is vital for trade.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
