HS Code for Fluorine

Fluorine is classified under HS code 2801.30 because it is a primary chemical element belonging to the halogen group. According to the General Rules of Interpretation (GRI 1), products are classified according to the terms of the headings and any relative section or chapter notes. Chapter 28 covers inorganic chemicals, and heading 2801 specifically lists fluorine, chlorine, bromine, and iodine. Fluorine is the most electronegative and reactive of all elements, typically handled as a compressed gas in specialized cylinders. The classification 2801.30 is a shared subheading for both fluorine and bromine. This classification is strictly for the pure elemental form; once fluorine is reacted with other elements to form compounds, it moves to other headings such as 2826 (fluorides) or 2812 (halides). The determination of this code relies on the chemical purity and the absence of other bonding elements that would categorize it as a compound rather than a pure halogen element. Furthermore, the Harmonized System Explanatory Notes (HSEN) for heading 2801 clarify that these elements remain classified here even if they are put up in small quantities for retail sale or as laboratory reagents. The physical state of the product—usually a pale yellow gas—is a key identifier for customs authorities. Importers must ensure that the purity levels meet the criteria for elemental halogens to avoid misclassification into the broader category of inorganic acids.

Products Included

• Elemental fluorine gas
• Compressed fluorine in cylinders
• Liquid fluorine (refrigerated)
• Bromine (as it shares the 2801.30 subheading)
• High-purity fluorine for semiconductor etching

Common Misclassification

Fluorine is frequently misclassified under HS code 2811.11, which is the code for hydrogen fluoride (hydrofluoric acid). While fluorine is used to produce this acid, the elemental gas and the acid are distinct chemical entities. Another common error is using 2812.19 for other halides; however, 2812 is reserved for non-metal halides and oxides, not the pure elements themselves. Additionally, natural minerals containing fluorine, such as fluorspar, must be classified in Chapter 25 (2529.21/22) rather than Chapter 28.

FAQ

What is the HS code for fluorine?

The HS code for elemental fluorine is 2801.30, which also includes bromine.

Is fluorine gas classified differently if it is liquid?

No, elemental fluorine remains under 2801.30 regardless of whether it is in a gaseous or liquefied state, provided it is not mixed with other elements.
