HS Code for Thorium

Thorium is classified under HS code 2844.30, a category that includes uranium depleted in U235, thorium, and their various forms such as alloys, dispersions, and cermets. As a radioactive chemical element, thorium is placed in Chapter 28, which covers inorganic chemicals and precious metal compounds, specifically within the section for radioactive elements and isotopes (2844). The classification 2844.30 is used for thorium in its elemental metallic form as well as its alloys. Thorium is a naturally occurring radioactive metal that is increasingly studied for its potential as a nuclear fuel. The Harmonized System groups thorium with depleted uranium because both are fertile materials used in nuclear reactors but are not fissile in the same way as U235 or plutonium. This code covers the raw metal and semi-manufactured forms like bars, rods, or wires, provided they are not further worked into specific finished articles.

Products Included

• Thorium metal in unwrought form
• Thorium alloys (e.g., magnesium-thorium alloys)
• Thorium bars, rods, and wires
• Thorium powder
• Cermets containing thorium

Common Misclassification

Thorium is sometimes misclassified under 8112.92 or 8112.99, which cover other base metals and articles thereof. However, because thorium is radioactive, Note 1 to Chapter 28 dictates that it must be classified under 2844. It may also be confused with 2844.10 (Natural uranium) or 2844.20 (Enriched uranium and plutonium) depending on the specific radioactive content of the shipment.

FAQ

What is the HS code for Thorium?

Thorium metal, its alloys, and dispersions are classified under HS code 2844.30.

Is thorium classified differently if it is in powder form?

No, thorium powder is still classified under 2844.30 as it is considered a form of the element or its alloys within the scope of that heading.
