HS Code for Quicksilver

Quicksilver, the common name for the element mercury, is classified under HS code 2805.40. This code is found in Chapter 28, which encompasses inorganic chemicals and precious metal compounds. Heading 2805 covers alkali or alkaline-earth metals, rare-earth metals, and mercury. Mercury is unique among metals for being liquid at standard temperature and pressure, which historically led to the name "quicksilver." The subheading 2805.40 is specifically dedicated to this element in its pure, unalloyed form. The classification applies to the metal regardless of its intended use, whether for industrial thermometers, barometers, or chemical catalysis. It is typically traded in standard steel flasks containing 34.5 kg of the liquid metal. The classification is based on the chemical purity of the element. It is important to note that this code is for the element itself; chemical compounds where mercury is chemically bonded with other elements are classified elsewhere in the tariff schedule.

Products Included

• Elemental mercury (quicksilver)
• Liquid mercury in steel flasks
• High-purity mercury for laboratory use
• Technical grade mercury for industrial applications
• Distilled mercury metal

Common Misclassification

Quicksilver is often confused with mercury compounds, which are classified under heading 2852. Heading 2852 covers both inorganic and organic compounds of mercury, such as mercury chloride or methylmercury. Another potential misclassification is 3824.99 for chemical mixtures. However, if the product is the pure element mercury, 2805.40 is the only correct code. Amalgams (alloys of mercury with other metals) are also excluded from 2805.40 and are generally classified under 2853 or in Chapter 71 if they contain precious metals.

FAQ

What is the HS code for liquid mercury?

Liquid mercury, also known as quicksilver, is classified under HS code 2805.40.

Are mercury-filled thermometers classified under 2805.40?

No, finished products like thermometers are classified under heading 9025. HS code 2805.40 only covers the raw elemental metal.
