HS Code 81.09 – Zirconium; articles thereof, including waste and scrap

HS code 8109 is a 4-digit heading in the Harmonized System that covers: Zirconium; articles thereof, including waste and scrap. HS Code 8109 covers Zirconium and articles thereof, including waste and scrap. Zirconium is a lustrous, grayish-white transition metal renowned for its exceptional corrosion resistance, high melting point, and low neutron absorption cross-section, making it indispensable in specific high-tech applications. Its primary use is in nuclear power generation, particularly in the form of Zircaloy alloys for fuel rod cladding, due to its ability to withstand extreme conditions within reactor cores. Beyond nuclear applications, zirconium is vital in the chemical processing industry for heat exchangers and piping, in high-temperature ceramics, and in certain medical instruments. The scope of this heading encompasses zirconium in its raw forms (sponges, ingots, bars, rods, plates, sheets, foil, tubes, pipes) and identifiable articles predominantly made of zirconium, along with its waste and scrap for recycling. As with other metals in Chapter 81, this classification falls under Section XV (Base metals and articles of base metals). Accurate classification under 8109 is crucial for trade compliance, especially given the dual-use nature of zirconium for nuclear applications, which triggers strict export controls, non-proliferation regulations, and specific licensing requirements. Understanding the definition of 'articles thereof' is key to differentiating between basic forms and more complex components.

Zirconium sponges, Zirconium ingots, Zirconium bars, Zirconium rods, Zirconium plates, Zirconium sheets, Zirconium foil, Zirconium tubes, Zirconium pipes, Zirconium fasteners, Zircaloy nuclear fuel cladding, Zirconium heat exchangers, Zirconium chemical processing equipment, Zirconium medical instruments, Zirconium dioxide ceramics, Zirconium dental implants, Zirconium waste scrap, Zirconium welding electrodes, Zirconium corrosion-resistant linings, Zirconium crucibles, Zirconium pumps, Zirconium reactor vessels, Zirconium target materials

Misclassification under HS 8109 often occurs due to the specialized nature of zirconium and its alloys. A common mistake is confusing Zircaloy (a specific zirconium alloy) with pure zirconium or classifying finished nuclear reactor components solely under 8109 instead of more specific headings in Section XVI (Machinery and mechanical appliances) or even under specific dual-use goods categories if the item is a controlled assembly. Additionally, zirconium chemical compounds (e.g., zirconium dioxide for ceramics) might be mistakenly placed here instead of Chapter 28 (Inorganic chemicals). Care must be taken to distinguish between raw metal, articles predominantly of zirconium, and complex assemblies where zirconium is a component.

In 2025, the top exporters of HS code 8109 in UN Comtrade data were the United States ($266M, 54% of world exports), China ($103M) and Germany ($40M). World exports came to about $495M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

In 2025, the top importers of HS code 8109 in UN Comtrade data were the United States ($122M, 18% of world imports), South Korea ($67M) and Canada ($67M). World imports came to about $666M, adding countries' reported figures and partner-based estimates for those that did not report (UN Comtrade data). Countries that did not report 2025 data are estimated from partner records, which can understate them.

HS code 8109 is a 4-digit heading under Chapter 81 of the Harmonized System. The first 2 digits (81) identify the chapter, and digits 3-4 (09) specify the heading. This code contains multiple 6-digit subheadings for precise product classification.
