HS Code for Scrap zirconium

HS code 810939 is a highly specific classification for zirconium waste and scrap. The primary defining characteristic for this code is the chemical composition, specifically the ratio of hafnium to zirconium. Zirconium and hafnium are chemically similar and often found together in nature. For nuclear applications, zirconium must be nearly hafnium-free because hafnium absorbs neutrons. Therefore, the industry distinguishes between nuclear-grade and industrial-grade zirconium. This specific code, 810939, applies to scrap containing not less than 1 part hafnium to 500 parts zirconium by weight. This distinction is critical for regulatory compliance and export controls, as zirconium is a dual-use material. The classification covers waste generated during the fabrication of zirconium parts or from the decommissioning of industrial equipment containing zirconium alloys.

Products Included

• Industrial-grade zirconium scrap
• Zirconium alloy turnings with high hafnium content
• Zirconium waste from chemical processing equipment
• Hafnium-bearing zirconium shavings

Common Misclassification

The most common misclassification occurs with HS code 810931, which is for zirconium waste and scrap containing less than 1 part hafnium to 500 parts zirconium (nuclear-grade). Using the wrong code can lead to significant legal issues due to international nuclear non-proliferation treaties. It is also sometimes confused with 810929, which covers unwrought zirconium.

FAQ

What is the HS code for scrap zirconium?

For scrap containing at least 1 part hafnium to 500 parts zirconium, the HS code is 810939.

Why is the hafnium ratio important for classification?

The ratio determines if the material is industrial-grade or nuclear-grade, which dictates different regulatory requirements and different HS subheadings.
