HS-6 · Subheading
292021
Esters; phosphite esters and their salts; their halogenated, sulphonated, nitrated or nitrosated derivatives, dimethyl 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 292021 when importing or exporting dimethyl phosphite, a chemical used primarily in agricultural applications and as a solvent. For instance, shipments of this compound may be included in formulations for pesticides or herbicides.
Dimethyl phosphite is distinct from other esters under the same heading, such as HS-6 292022, which covers diethyl phosphite. While both are phosphite esters, their different alkyl groups lead to varied uses and regulatory considerations.
This HS-6 line specifically covers dimethyl phosphite and its derivatives, which can be halogenated, sulphonated, nitrated, or nitrosated. Understanding these distinctions is crucial for compliance with customs regulations and proper classification.
When dealing with phosphite esters, it’s important to check the specific chemical structure and intended use to ensure accurate HS code assignment, as similar compounds may fall under different classifications.
