Waste Marine Grease from Ship Engine Bearings
This is waste grease collected from the bearings of marine diesel engines, containing minor soap thickeners from vegetable fatty acids under 10% by weight. It qualifies under HTS 2710.99.32.00 as a waste of lubricating greases with low fatty acid salt content derived from used marine equipment. The material is a spent lubricant no longer suitable for its original purpose.

Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If containing over 10% fatty acid salts
Higher soap content in grease formulation shifts to subheading for greases with >10% salts of animal/vegetable origin.
If re-refined and sold as recovered base oil
Processed waste oils meeting recovery criteria for reuse as lubricants fall under Chapter 38 for residual products.
If hydraulic system waste not classified as grease
Liquid waste oils from hydraulic uses without grease consistency go to motor oil waste subheading.

Import Tips & Compliance
• Verify fatty acid salt content via lab analysis to confirm ≤10% threshold; obtain waste manifests proving origin as spent grease
• Common pitfall: misclassifying as non-waste if still usable
