Heading 2931Other organo-inorganic compounds

Chapter 29: Organic chemicals

Plain-language overview

Use HS-6 293148 when importing or exporting non-halogenated organo-phosphorous derivatives like 3,9-dimethyl-2,4,8,10-tetraoxa-3,9-diphosphaspiro[5.5] undecane 3,9-dioxide. This compound is often used in specialized chemical applications, including as a reagent in organic synthesis.

This code specifically covers organo-phosphorous compounds that do not contain halogens, distinguishing it from HS-6 293149, which includes halogenated derivatives. If your product contains halogens, you will need to refer to the latter code instead.

The HS-4 heading 2931 narrows the focus to other organo-inorganic compounds, which can include a variety of chemical structures. Understanding the specific characteristics of your product is crucial for correct classification.

When assessing whether to use this HS-6 code, consider the chemical structure and intended use of your product. For example, if you are dealing with a phosphorous compound that serves as a flame retardant or an additive in polymers, this code may apply.
