HS Code for Synthetic lubricant

Synthetic lubricants are classified under HS code 3403.99 when they are lubricating preparations that do not contain petroleum oils or oils obtained from bituminous minerals. This classification is part of Chapter 34, which covers soap, organic surface-active agents, and lubricating preparations. The specific subheading 3403.99 is used for preparations intended for the lubrication of machinery, vehicles, or other equipment, provided they are not used for the treatment of textile materials (which would fall under 3403.91). The defining characteristic of this code is the chemical composition: it must be a synthetic-based lubricant, such as those made from polyalphaolefins (PAO), esters, or silicones, and it must contain 0% petroleum oil. If even a small amount of petroleum oil is added as a carrier or additive, the classification may shift. This code is vital for high-performance industrial lubricants that operate in extreme temperatures where traditional mineral oils would fail. The absence of petroleum is the primary legal note that dictates this classification over heading 2710.

Products Included

• Full synthetic engine oils (0% petroleum)
• Synthetic hydraulic fluids (non-petroleum)
• Silicone-based lubricating greases
• Synthetic gear oils for industrial machinery
• Ester-based biodegradable lubricants

Common Misclassification

The most frequent misclassification is with HS code 2710.19, which covers lubricants containing 70% or more by weight of petroleum oils. Another common error is using 3403.19, which is for lubricating preparations that contain petroleum oils but less than 70% by weight. If the lubricant is intended for the oiling or greasing of textile fibers or leather, it must be classified under 3403.91. Finally, pure chemical compounds that act as lubricants but are not "preparations" might be classified in Chapter 29.

FAQ

What is the HS code for Synthetic lubricant?

The HS code for lubricating preparations not containing petroleum oils or oils from bituminous minerals (and not for textile treatment) is 3403.99.

Can a lubricant with 1% petroleum oil be classified under 3403.99?

No. HS code 3403.99 is strictly for preparations containing no petroleum oils. If the product contains any amount of petroleum oil or oils from bituminous minerals, it must be classified under the 3403.11 or 3403.19 series, depending on its use and petroleum content.
