HS Code 3403.99 – Lubricating preparations; other than for the treatment of textile and similar materials, not containing petroleum oils or oils obtained from bituminous minerals
HS code 3403.99 is the 6-digit subheading for lubricating preparations, other than for the treatment of textile and similar materials, not containing petroleum oils or oils obtained from bituminous minerals. It is used for synthetic compressor oils, food-grade lubricants, silicone greases, biodegradable hydraulic fluids and fluorinated greases.
What HS 3403.99 covers
This code covers lubricating preparations (other than those for textiles and similar materials) that do *not* contain petroleum oils or oils obtained from bituminous minerals. This category encompasses a wide range of high-performance synthetic and bio-based lubricants, greases, and specialty fluids designed for applications where petroleum-based products are unsuitable or where superior performance is required. Examples include food-grade lubricants, silicone greases, synthetic compressor oils, and biodegradable hydraulic fluids. These products are traded globally by specialty chemical companies and lubricant manufacturers, serving diverse industries such as food and beverage, pharmaceuticals, aerospace, electronics, and renewable energy. Importers seek advanced solutions for critical equipment, while exporters leverage cutting-edge chemical formulations. Key aspects include specific performance criteria, environmental regulations, and safety certifications.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
