HS Code for Mercury

Mercury is classified under HS code 2805.40. This code is located within Chapter 28, which covers inorganic chemicals, precious metals, and radioactive elements. Heading 2805 is dedicated to alkali or alkaline-earth metals, rare-earth metals, scandium, yttrium, and mercury. Mercury, also known as quicksilver, is unique as it is the only metal that is liquid at standard temperature and pressure. Under GRI 1, mercury in its elemental form is classified here. This includes mercury that has been purified or distilled for industrial or laboratory use. However, it does not include mercury that has been put up in measured doses or forms for retail sale as a medicament (Chapter 30) or mercury compounds (which are generally classified in heading 2852). The classification is straightforward for the pure element, but care must be taken to ensure it is not an amalgam (an alloy of mercury with another metal). The trade of mercury is strictly regulated under the Minamata Convention, and its HS classification is vital for monitoring global movements of this hazardous substance.

Products Included

• Elemental mercury (quicksilver)
• Distilled or purified mercury
• Mercury in flasks or iron bottles
• Virgin mercury

Common Misclassification

Mercury is frequently misclassified under HS code 2852, which covers inorganic or organic compounds of mercury. However, 2805.40 is specifically for the element itself, not its compounds (like mercury chloride). Another common error involves amalgams. Amalgams of precious metals are classified in heading 2843, while other amalgams are generally found in heading 2853. If mercury is contained within a measuring instrument, such as a thermometer or barometer, the entire device is classified in Chapter 90 (e.g., 9025.11) rather than as mercury.
