Non-halogenated organo-phosphorous derivatives; methylphosphonic acid

Heading 2931Other organo-inorganic compounds

Chapter 29: Organic chemicals

Plain-language overview

Use HS-6 293144 when importing or exporting methylphosphonic acid, a non-halogenated organo-phosphorous compound often used in chemical synthesis and as a precursor in various applications. For example, it can be found in formulations for agricultural chemicals or as an intermediate in the production of flame retardants.

This code specifically applies to methylphosphonic acid, distinguishing it from other organo-phosphorous derivatives like those classified under HS-6 293145, which covers halogenated variants. Understanding this distinction is crucial for compliance and accurate tariff classification.

Methylphosphonic acid is typically shipped in bulk containers or drums, and its applications span from industrial uses to research purposes. If you're dealing with similar compounds, ensure you check the specific HS code to avoid misclassification.

When considering shipments, be aware that methylphosphonic acid may require specific handling and documentation due to its chemical properties. Always consult with your customs broker to ensure proper compliance with regulations.
