HS Code for Metaxylene

Metaxylene, also known as m-xylene, is classified under HS code 2902.42. This classification falls within Chapter 29 (Organic Chemicals), specifically under the heading for cyclic hydrocarbons (2902). The xylenes are a group of three benzene derivatives with two methyl substituents. To be classified under 2902.42, the metaxylene must be a separate chemically defined isomer with a purity level typically exceeding 95% by weight. The Harmonized System distinguishes between specific isomers of xylene (ortho-, meta-, and para-) to facilitate precise trade monitoring and tariff application. Metaxylene is primarily used as a chemical intermediate in the production of isophthalic acid, which is a precursor for various resins and polymers. The classification logic is based on the chemical identity of the hydrocarbon and its high degree of purity, which excludes it from the petroleum oil classifications of Chapter 27.

Products Included

• Pure m-Xylene (Metaxylene)
• Metaxylene with a purity of 95% or more
• m-Xylene containing small amounts of ethylbenzene or other xylene isomers as impurities

Common Misclassification

Metaxylene is most commonly misclassified under HS code 2902.44, which is the code for "Mixed xylene isomers." This occurs when the product is a blend of ortho, meta, and para isomers rather than a purified single isomer. It is also sometimes confused with HS code 2707.30 (Xylols/Xylenes), which applies to lower-purity aromatic hydrocarbon mixtures derived from the distillation of coal tar or petroleum where the xylene content is less than 95%.

FAQ

What is the HS code for Metaxylene?

The HS code for high-purity metaxylene (m-xylene) is 2902.42.

What is the purity requirement for Chapter 29 xylenes?

Generally, for a specific xylene isomer to be classified in 2902.41, 2902.42, or 2902.43, it must have a purity of 95% or more by weight. Lower purity mixtures are classified in Chapter 27 or under 2902.44.
