U.S. exports of Antifreezing Preparations & Deicing Fluids (SITC 59733) totaled $19.4M in August 2026.
Importers of Antifreezing Preparations & Deicing Fluids paid $187K in duties in August 2026, an average duty rate of 4.31% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Antifreezing Preparations & Deicing Fluids imports of $4.3M in August 2026 ran 27% above the year-to-date monthly average of $3.4M.
Last updated: August 2026 dataEthylene glycol– and propylene glycol–based formulations account for the bulk of trade in SITC 59733, serving automotive cooling systems, aircraft ground deicing operations, and industrial freeze-protection applications. The distinction between ethylene glycol (more toxic, lower cost) and propylene glycol (food-grade compatible, used in aircraft and food-processing environments) is commercially and regulatorily significant, affecting both end-use approvals and environmental disposal requirements. Aviation deicing fluids additionally must meet AMS (SAE Aerospace Material Specification) standards, adding a layer of specification compliance beyond standard customs classification.

Aircraft ground deicing and anti-icing fluids must conform to SAE AMS 1424 (Type I) or AMS 1428 (Types II, III, IV) standards, and must be approved by the FAA for use at US airports. Importers supplying aviation customers should confirm that their product holds the appropriate AMS qualification and that documentation accompanies each shipment.
Yes. Concentrated antifreeze (requiring dilution before use) and pre-diluted ready-to-use coolant may be classified differently depending on their formulation and the proportion of active glycol content. Importers should review the product's concentration level and additive package against the applicable HTS subheadings to ensure correct classification, as duty treatment can differ.
