HS-4 · Heading
2852 — Inorganic or organic compounds of mercury, excluding amalgams, whether or not chemically defined
Chapter 28: Inorganic chemicals
Plain-language overview
Use HS-4 2852 when importing inorganic or organic compounds of mercury, like mercuric chloride or mercury sulfide. These compounds are often used in laboratory settings or as chemical intermediates in manufacturing processes.
When deciding between the HS-6 lines, consider whether your product is chemically defined. For example, HS-6 285210 applies to specific compounds like mercuric oxide, which have a clear chemical definition. If your product lacks a precise chemical definition, it falls under HS-6 285290.
It's important to note that both subheadings exclude amalgams. If your shipment includes mercury amalgams, you will need to classify it under a different heading. Make sure to check the specific chemical composition to avoid misclassification.

Questions & answers
For orientation only—the binding text is your national tariff and the WCO nomenclature your country uses.
- What types of mercury compounds fall under HS-4 2852?
- HS-4 2852 covers inorganic or organic compounds of mercury, excluding amalgams, including both chemically defined and not chemically defined compounds.
- How can I tell if my mercury compound is chemically defined?
- Chemically defined compounds have a specific chemical structure and composition, such as mercuric oxide. If your product lacks this, it may fall under the not chemically defined category.
- Are there any restrictions on importing mercury compounds?
- Yes, importing mercury compounds may be subject to specific regulations due to their hazardous nature. Always check with local authorities for compliance.
- What should I do if my product is an amalgam?
- If your product is a mercury amalgam, it cannot be classified under HS-4 2852. You will need to find the appropriate heading for amalgams.
- Can I use HS-6 285290 for any mercury compound?
- HS-6 285290 is specifically for inorganic or organic mercury compounds that are not chemically defined. Ensure your product fits this description.
