HS Code for Argon

Argon is classified under HS code 280421, which specifically covers "Gases, rare; argon." This classification is found within Chapter 28, dedicated to inorganic chemicals, and precisely identifies argon as a distinct rare gas. The code applies to argon in its elemental form, whether gaseous or liquefied, and regardless of its purity level, provided it remains essentially argon. This specific designation is crucial for international trade, ensuring that this particular inert gas is accurately categorized and distinguished from other rare gases or gas mixtures. The clarity of this code facilitates consistent customs procedures globally.

Products Included

• Gaseous argon (compressed)
• Liquid argon (cryogenic)
• High-purity argon
• Industrial grade argon
• Argon for welding applications (pure)
• Argon for lighting applications (pure)

Common Misclassification

A common misclassification for argon could occur with HS 280429, which covers "Other rare gases." However, since argon has its own specific subheading (280421), it should not be classified under the general "other rare gases" category. HS 280429 is reserved for rare gases such as neon, krypton, and xenon. Another potential area of confusion might be with other elemental gases like HS 280410 (Hydrogen) or HS 280430 (Nitrogen); however, these are chemically distinct elements and are therefore classified separately. It is important to note that mixtures containing argon with other gases are typically classified differently, often under HS 285390.

FAQ

What is the HS code for Argon?

The HS code for Argon is 280421, specifically designated for argon as a rare gas.

Is argon gas mixture classified under HS 280421?

HS 280421 specifically covers pure argon. Mixtures containing argon with other gases, such as those used in welding (e.g., argon-CO2 mixtures) or specialized industrial applications, are typically classified under different HS codes. These mixtures often fall under HS 285390, which covers "Other inorganic compounds; liquid air; compressed air; amalgams other than amalgams of precious metals," or other relevant headings depending on the specific composition and intended use, provided they do not form a distinct chemical compound.
