Inorganic or organic compounds of mercury, whether or not chemically defined, excluding amalgams
4 declarable lines
Heading 2852 covers inorganic or organic compounds of mercury, whether or not chemically defined, but not amalgams. It splits first by whether the compound is chemically defined, then by the specific named compounds, with a residual line at each level. Amalgams and mercury metal itself are classified elsewhere.
Products in this heading
- Mercuric oxide powder
- Mercuric cyanide
- Mercuric oxycyanide
- Mercuric potassium cyanide
- Mercury albuminate
- Mercury tannate
- Mercury phosphide
- Mercuric chloride (chemically defined, not named in the heading text)
How to choose the right subheading
- Whether the product is an amalgam, which is excluded from this heading entirely.
- Whether the mercury compound is chemically defined or not.
- Whether a chemically defined compound is one of the four named in 2852.10.10.00.
- Whether the product is an albuminate, tannate or phosphide of mercury.
- Whether the product falls in the residual 'other' line at either level.
Often confused with
- Heading 2805Mercury metal (quicksilver)
The element itself is covered by the alkali and alkaline-earth metals heading, not by the compounds heading.
- Heading 2843Amalgams of precious metals
Amalgams of precious metals are classified with precious metal compounds.
- Heading 2853Amalgams other than those of precious metals
Heading 2852 expressly excludes amalgams; non-precious amalgams fall in the residual inorganic heading.
- Heading 2843Inorganic compounds of precious metals
Compounds of precious metals go to the precious metals heading even when they contain mercury.
Frequently asked questions
What is the HTS code for mercuric oxide?
Mercuric oxide is classified under 2852.10.10.00, which covers mercuric oxide, mercuric cyanide, mercuric oxycyanide and mercuric potassium cyanide. The general (MFN) rate for that line is Free.
What is the duty on other chemically defined mercury compounds?
Chemically defined mercury compounds not named in the first line of the heading fall under 2852.10.90.00. The general (MFN) rate for that line is 3%.
How do I classify mercury albuminate or mercury tannate?
Albuminates, tannates and phosphides of mercury are classified under 2852.90.05.00. The general (MFN) rate for that line is Free.
