HS-6 · Subheading
292023
Esters; phosphite esters and their salts; their halogenated, sulphonated, nitrated or nitrosated derivatives, trimethyl phosphite
Heading 2920 — Esters of other inorganic acids of non-metals (other than of hydrogen halides) and their salts, their halogenated, sulphonated, nitrated or nitrosated derivatives
Chapter 29: Organic chemicals
Plain-language overview
Use HS-6 292023 when importing or exporting trimethyl phosphite, a chemical commonly used in the production of pesticides and pharmaceuticals. For example, a shipment of trimethyl phosphite in 200-liter drums would fall under this code.
This code specifically covers esters like trimethyl phosphite, which are derived from phosphorous acid. In contrast, HS-6 292024 pertains to other phosphite esters, so ensure you're classifying correctly based on the specific chemical structure.
Trimethyl phosphite is often used as a reagent in organic synthesis and can also serve as a stabilizer in certain chemical formulations. If you’re dealing with halogenated derivatives, you might need to look at additional codes.
When considering shipments, be aware that trimethyl phosphite may be subject to specific import regulations due to its applications in chemical manufacturing. Always check for any necessary permits or restrictions.
