Antifoam Additive Based on Polyglycol Methylphosphonate
An industrial antifoam agent composed of polyglycol esters of methylphosphonic acid for use in chemical manufacturing and wastewater treatment. Classified under HTS 3824.92.00.00 due to its specific chemical structure as polyglycol esters of methylphosphonic acid. It controls foam formation in processing by altering surface tension.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If formulated as a surface-active preparation for industrial defoaming
Defoaming agents primarily functioning as surfactants are classified in Chapter 34, not pure chemical substances.
If for other antifoam chemical mixtures without specific phosphonate esters
Nonspecific chemical preparations for industrial use fall into the broader 3824.99 category.
If considered heterocyclic compounds with phosphorus rather than esters
Certain phosphonate structures may be reclassified under Chapter 29 heterocyclic compounds.

Import Tips & Compliance
• Provide detailed formulation certificates proving polyglycol ester content to prevent reclassification
• Comply with DOT hazardous material shipping regulations if concentration exceeds flammability thresholds
• Label clearly as chemical preparation under 3824 to distinguish from finished defoamers in 3402
