How do I determine the correct HS-6 code for my product?

Identify the key components of your product. If it contains lead, use **381111**; if not, choose **381119**. For lubricating oil additives, check if they contain petroleum oils.

Can I use HS-4 3811 for products not specifically listed?

Yes, if your product serves a similar purpose as those listed under HS-4 3811, it may fall under **381190**, which covers other prepared additives.

What are the implications of using lead compounds in anti-knock preparations?

Using lead compounds can affect your classification under **381111** and may have additional regulatory requirements due to environmental concerns.

Are there any special import regulations for these products?

Yes, certain products, especially those containing lead or specific chemicals, may require additional documentation or compliance with safety regulations.

HS-4 · Heading

3811 — Anti-knock preparations, oxidation and gum inhibitors, viscosity improvers, anti-corrosive preparations and the like, for mineral oils (including gasoline) or other liquids used for the same purposes

Chapter 38: Miscellaneous chemical products

Plain-language overview

Use HS-4 3811 when importing anti-knock preparations or additives for mineral oils, like a shipment of gasoline with lead-based anti-knock agents. This heading covers products that enhance fuel performance and stability.

When deciding between 381111 and 381119, consider the composition of your anti-knock preparations. If they contain lead compounds, use 381111; otherwise, choose 381119 for non-lead alternatives.

For lubricating oil additives, determine if your product contains petroleum oils. If it does, classify it under 381121; if not, use 381129. This distinction is crucial for compliance and accurate tariff classification.

The remaining line, 381190, includes other prepared additives that serve similar purposes but don't fit into the previous categories. Use this for products like oxidation inhibitors or viscosity improvers not specifically listed elsewhere.
