HS Code 28.01 – Fluorine, chlorine, bromine and iodine

What HS 28.01 covers

HS Code 2801 specifically covers fluorine, chlorine, bromine, and iodine in their elemental forms. These are highly reactive non-metals belonging to the halogen group. This heading is crucial for distinguishing these fundamental chemical elements from their vast array of compounds, which typically fall under other headings within Chapter 28 (e.g., metal halides) or Chapter 29 (organic halogenated derivatives). The scope includes these elements in various purities and physical states, such as gaseous chlorine, liquid bromine, solid iodine, and elemental fluorine. This classification is vital for trade compliance due to the hazardous nature of many halogens, necessitating strict handling, packaging, and transportation regulations, often reflected in specific tariffs or import/export controls. For instance, chlorine is a potent disinfectant and industrial chemical, bromine is used in flame retardants and pharmaceuticals, and iodine is essential in medical applications and catalysts. Historically, the trade in these elements has been significant, driven by their widespread use across diverse industries from water treatment and petrochemicals to electronics and medicine. Proper classification ensures accurate duty assessment, compliance with environmental and safety standards, and adherence to chemical weapons conventions or precursor controls, making it a cornerstone for professionals dealing with basic inorganic chemicals. This heading forms the initial entry for elemental halogens within Chapter 28, which broadly covers inorganic chemicals, thus setting a clear boundary for these specific elements before their compounds are considered.

Examples

A chemical company in the United States imports high-purity iodine flakes from Chile for use in pharmaceutical manufacturing, transported via ocean freight. Simultaneously, a European water treatment facility regularly imports liquid chlorine in specialized tanks from Germany, ensuring a steady supply for municipal water disinfection. Furthermore, a Chinese manufacturer exports industrial-grade bromine to India for the production of flame retardants, navigating complex international hazardous goods regulations via container ships. Another scenario involves a Japanese electronics firm importing highly purified fluorine gas from South Korea for specialized semiconductor etching processes, requiring secure air cargo for transport. Finally, a Brazilian chemical distributor imports technical grade bromine from Israel to supply local industries for agricultural chemicals and dyestuffs.

Codes often confused with 28.01

Common mistake. A common mistake is confusing elemental halogens (2801) with their compounds. For instance, sodium hypochlorite, a chlorine compound used as bleach, falls under heading 2828, not 2801. Similarly, potassium iodide, an iodine compound, is classified under 2827. Traders might also misclassify mixtures containing halogens as the pure element, when such mixtures could fall under heading 3824 (prepared binders, chemical products not elsewhere specified). The critical distinction lies in whether the product is the uncombined element or a chemical compound formed with other elements. Misclassification often arises from a lack of understanding of chemical nomenclature and the specific scope of 'elemental' forms versus 'compounds' within the Harmonized System.

Top exporters and importers of HS code 2801, 2025

In 2025, the largest exporter of HS code 2801 in UN Comtrade data was Chile, with 49% of world exports; the largest importer in UN Comtrade data was China, with 26% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built

109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
