About HS Code 293144

This HS code covers methylphosphonic acid, a fundamental non-halogenated organo-phosphorous compound. It is predominantly used as an intermediate in the production of various specialty chemicals, including flame retardants, chelating agents, and corrosion inhibitors. Chemical manufacturers and companies involved in polymer additives or water treatment are the primary traders of this acid. Its strong acidic nature and ability to form stable complexes are key to its industrial utility, making it a valuable building block for advanced material science and chemical synthesis.

Products Under This Code

Methylphosphonic acid, MPA, Methanephosphonic acid, Methylphosphonic acid monohydrate

Real World Examples

Lanxess, Solvay, Sigma-Aldrich (now Merck KGaA), ICL Group

Common Misclassification

Can be confused with other phosphonic acids (e.g., 2931.90 for 'other' organo-phosphorous compounds) or even inorganic phosphorous acids (Chapter 28) due to its acidic nature.
