About HS Code 280540

Mercury, a unique heavy metal, plays a complex role in international trade due to its dual nature as both a valuable industrial chemical and a significant environmental hazard. Historically, it was widely used in thermometers, barometers, and electrical switches, but its trade has seen a dramatic shift towards highly regulated and restricted movements. Today, its primary legitimate uses are in specific industrial processes, such as chlor-alkali production (though declining), gold and silver mining (often artisanal and illegal), and in certain scientific instruments and dental amalgams. Major importers are often countries with legacy industrial infrastructure or those where artisanal mining persists, while exporters are typically countries with existing stockpiles or those that have historically mined it. Key things to know include the stringent international regulations, such as the Minamata Convention, which aims to phase out mercury use and trade, making its legitimate movement highly controlled and often requiring specific permits and declarations. Illicit trade, particularly for gold extraction, remains a concern, highlighting the need for robust customs enforcement and environmental monitoring. The global trend is towards reduction and elimination of mercury in products and processes, impacting its trade dynamics significantly.

Products Under This Code

Liquid mercury, mercury compounds for specific industrial uses, mercury for dental amalgam, mercury for scientific instruments, mercury for fluorescent lamps

Real World Examples

Elemental mercury, mercury thermometers (historical), dental amalgam capsules, mercury vapor lamps, mercury switches (historical)

Common Misclassification

This code specifically covers elemental mercury. Mercury compounds would fall under other codes like 2852.10 (inorganic or organic compounds of mercury), which can be confused due to the shared 'mercury' component but differ in chemical form.

Products Classified Under 2805.40

Industry

This code belongs to the Chemicals industry.

Trade Overview

Top historical exporters include Spain and Kyrgyzstan, while importers vary based on specific industrial needs and regulatory frameworks, with many countries now restricting or banning its import.
