HS Code 3819 — Hydraulic Brake and Transmission Fluids

This category includes specialized liquids used in hydraulic systems, such as automotive braking or power steering. These fluids are formulated to operate under high pressure and temperature without boiling or compressing.

What's included

DOT 3 brake fluid
DOT 4 brake fluid
Hydraulic power steering fluid
Synthetic hydraulic transmission fluids

What's excluded

High petroleum hydraulic oils → use 2710 (If the fluid contains 70% or more petroleum oil, it belongs in Chapter 27.)

Common examples

Glycol-based brake fluid
Central hydraulic system fluid
Clutch fluid
Racing brake fluid

Frequently asked questions

Can I use this code for all hydraulic oils?

Only if the oil content is under 70%. Most standard mineral hydraulic oils are 70%+ petroleum and fall under 2710.

Trade & shipping notes

Typical duty range: 0% - 6.5%
Documentation: MSDS must show the percentage of petroleum oil to justify heading 3819 over 2710.
Typical shipping mode: LCL
Top exporters: United States, Germany, United Kingdom, Japan
Top importers: China, Mexico, Canada, India

Key takeaway

Classification depends entirely on the ratio of petroleum oil; under 70% is the threshold.
