HS Code 3819Hydraulic brake fluids and other prepared liquids for hydraulic transmission, not containing or containing less than 70% by weight of petroleum oils or oils obtained from bituminous minerals
1 six-digit code · Heading 19 of 27 in Chapter 38 · World Customs Organization Harmonized System
HS code 3819 is the customs heading for hydraulic brake fluid and similar liquids that carry force through a hydraulic system. Below you will see what fits here, how to tell it from nearby headings, and where to look up trade records.
Heading 3819does not subdivide further in the WCO nomenclature: goods answering to “Hydraulic brake fluids and other prepared liquids for hydraulic transmission, not containing or containing less than 70% by weight of petroleum oils or oils obtained from bituminous minerals” classify at the single six-digit code 381900. The heading is number 19 of 27 in Chapter 38, Chemical products n.e.c., which runs to 108 six-digit codes in all.

What HS code 3819 covers
In plain terms, this heading is for brake fluid. It also covers other prepared liquids used in hydraulic transmission. These liquids pass pressure from one part of a machine to another. A car's brake pedal is the most familiar example.
The official wording sets one test. The fluid must hold no petroleum oils, or less than 70 by weight of petroleum oils or oils obtained from bituminous minerals. Bituminous minerals are the tar and rock sources that many oil products come from.
Buyers often search for this heading as brake fluid HS code, hydraulic transmission fluid, or HSN code 3819. All of these point to the same place in the Harmonized System.
HS code 381900 and national tariff lines
The world system stops at six digits. Some countries add more digits for their own tariff. You may see the longer number called an HTS code, a tariff line or an HSN code, depending on the country.
Those extra digits are national, so they can differ from one country to the next. Check the tariff of the country you ship to or from. The first six digits stay the same worldwide.
How to classify brake and hydraulic fluids
Start with the oil content. If the fluid has no petroleum oil, or less than 70 by weight, heading 3819 is the likely fit. If the fluid has 70 or more by weight, it falls outside this heading and belongs with the petroleum oil headings elsewhere in the tariff.
Next, ask what the product does. Some neighbours look close but cover different goods:
- Anti-freeze and de-icing liquids go to heading 3820, even when they are used in vehicles.
- Additives that you mix into oils or fuel, such as anti-corrosives and viscosity improvers, go to heading 3811.
- Biodiesel and its mixtures go to heading 3826.

HS Code 3819: common questions
What is the HS code for hydraulic brake fluid?
Hydraulic brake fluid is classified under heading 3819, with the six-digit code 381900.
What does heading 3819 include?
It includes brake fluids and other prepared liquids used for hydraulic transmission, as long as they pass the petroleum oil test.
What if the hydraulic fluid contains 70 or more by weight of petroleum oil?
Then it is outside heading 3819. Fluids with a higher petroleum oil share are classified with petroleum oils instead.
What is the HSN code for brake fluid?
HSN is the name some countries use for the same system. Brake fluid is 3819, and national tariffs may add more digits after the first six.
Where does a chemical preparation go if it fits no other heading?
It may belong in heading 3824, which covers chemical preparations not named elsewhere.
