U.S. exports of Additives for Liquids Substituting for Mineral Oils (NES) (SITC 59729) totaled $107.0M in August 2026.
Importers of Additives for Liquids Substituting for Mineral Oils (NES) paid $1.3M in duties in August 2026, an average duty rate of 10.52% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule. Additives for Liquids Substituting for Mineral Oils (NES) imports of $11.9M in August 2026 ran 27% above the year-to-date monthly average of $9.4M.
Last updated: August 2026 dataCaptured under the 'not elsewhere specified' residual of SITC 597, these additives are formulated for synthetic or bio-based functional fluids — such as polyalkylene glycols, esters, or silicone-based fluids — that serve the same lubrication, cooling, or hydraulic roles as mineral oils but are chemically distinct from them. The NES designation means classification here is a fallback after confirming the product does not fit the more specific mineral-oil-additive or lubricating-oil-additive headings. Correct classification requires detailed knowledge of both the base fluid chemistry and the additive's intended function.

Products formulated for use in synthetic ester-based aviation lubricants, polyalkylene glycol hydraulic fluids, or silicone heat-transfer fluids — where the carrier is not petroleum-derived — would typically fall here. The NES designation applies when the additive's host fluid is a non-mineral-oil substitute, and the additive itself is not covered by a more specific heading.
A detailed technical data sheet specifying the chemical composition of both the additive and its intended host fluid is essential. Because the NES category is a residual, CBP may scrutinize whether the product belongs in a more specific heading; a binding ruling request can provide classification certainty before large shipments are committed.
