HS Code for Waste hydraulic fluid

Waste hydraulic fluids are classified under HS code 3825.50 as residual products of the chemical or allied industries. This heading is specifically designed to capture waste materials that are no longer fit for their original intended use. Unlike virgin hydraulic fluids, which are classified based on their chemical composition (often in Chapter 27 for mineral-based or Chapter 38 for synthetic-based), waste fluids are grouped by their status as industrial refuse. Subheading 3825.50 is a specific provision for hydraulic fluids, brake fluids, and anti-freeze fluids that have become contaminated, spent, or otherwise degraded during industrial or automotive processes. The classification is determined by the fact that the product is a waste stream intended for disposal, recycling, or recovery, rather than a primary product intended for sale as a lubricant or functional fluid.

Products Included

• Used mineral-based hydraulic oils
• Spent synthetic hydraulic fluids
• Contaminated brake fluids (hydraulic traction)
• Waste anti-freeze solutions and coolants
• Degraded transmission fluids used in hydraulic systems
• Recovered hydraulic fluids from machinery decommissioning

Common Misclassification

Waste hydraulic fluids are often misclassified under 2710.91 or 2710.99, which cover general waste oils. While 2710.99 is a broad category for waste petroleum oils, 3825.50 is more specific for hydraulic and brake fluids. Another common error is using 3819.00, which is strictly for new, prepared hydraulic fluids. If the fluid contains more than 50mg/kg of PCBs, it must be classified under 3825.41 or 2710.91 depending on the base.

FAQ

What is the HS code for Waste hydraulic fluid?

The specific HS code for waste hydraulic fluids, along with brake and anti-freeze fluids, is 3825.50.

Does this code include new hydraulic fluids?

No, new or virgin hydraulic fluids are typically classified under 3819.00 or within heading 2710 depending on their petroleum content.
