HS Code for Engine oil additive

Engine oil additives are classified under HS code 3811.21. This classification is situated within Chapter 38, which covers miscellaneous chemical products. Heading 3811 is dedicated to anti-knock preparations, oxidation inhibitors, gum inhibitors, viscosity improvers, anti-corrosive preparations, and other prepared additives for mineral oils (including gasoline) or for other liquids used for the same purposes as mineral oils. Subheading 3811.21 specifically identifies additives for lubricating oils that contain petroleum oils or oils obtained from bituminous minerals. These products are chemical preparations added to engine oil to enhance performance, protect engine components, or extend the life of the lubricant. To fall under this code, the preparation must be a mixture of active chemical substances, often diluted in a carrier oil.

Products Included

• Detergent and dispersant additives for motor oil
• Anti-wear (AW) and Extreme Pressure (EP) additives
• Viscosity index improvers containing petroleum oil
• Corrosion inhibitors for engine lubricants
• Friction modifiers for automotive oils

Common Misclassification

The most common misclassification is HS code 3811.29, which is for lubricating oil additives that *do not* contain petroleum oils (such as fully synthetic additives with non-petroleum carriers). Another error is classifying these products under 2710, which covers petroleum oils themselves. If the product is a finished lubricant (oil + additives), it belongs in 2710; if it is a concentrated preparation intended to be added to oil, it belongs in 3811. Additionally, pure chemical compounds that have not been 'prepared' or mixed as additives might be classified in Chapters 28 or 29.

FAQ

What is the HS code for engine oil additive?

The HS code for engine oil additives containing petroleum oil is 3811.21.

What if the additive is for fuel instead of oil?

Additives for fuel (like anti-knock preparations or fuel detergents) are classified under different subheadings of 3811, such as 3811.11 or 3811.19, rather than 3811.21.
