HS Code 8109.99 – Zirconium; other than unwrought, n.e.c. in heading no. 8109, containing not less than 1 part hafnium to 500 parts zirconium by weight
HS code 8109.99 is the 6-digit subheading for zirconium, other than unwrought, n.e.c. in heading no. 8109, containing not less than 1 part hafnium to 500 parts zirconium by weight. It is used for industrial-grade zirconium bars, zirconium plates, zirconium sheets, zirconium tubes and zirconium wire.
What HS 8109.99 covers
This HS code encompasses processed forms of zirconium, excluding unwrought material and waste/scrap, that contain a higher level of hafnium (not less than 1 part hafnium to 500 parts zirconium). These are typically semi-finished products like bars, rods, plates, sheets, tubes, and wires, intended for a wide range of industrial applications where zirconium's excellent corrosion resistance, high melting point, and strength are valued, but nuclear purity is not required. Industries utilizing these materials include chemical processing, medical devices, aerospace (non-nuclear parts), and consumer electronics. Importers and exporters are generally countries with robust manufacturing sectors that incorporate advanced materials. The trade focuses on material specifications, alloy compositions, and the specific forms required by diverse industrial end-users.

Codes often confused with 8109.99
Common mistake. This code is differentiated from 810991 by its higher hafnium content, and from 810929 by being in a processed form (not unwrought powder). It might be confused with finished articles of zirconium in other chapters if the item is a complete functional part.
Top exporters and importers of HS code 810999, 2025
In 2025, the largest exporter of HS code 810999 in UN Comtrade data was the United States, with 44% of world exports; the largest importer in UN Comtrade data was Spain, with 17% of world imports. Countries that did not report 2025 data are estimated from partner records, which can understate them.

How these figures are built
109 countries reported 2025 trade to UN Comtrade in HS 2022, and their own totals are used. Countries that did not report are estimated from what other countries recorded trading with them. Those estimates miss trade with other non-reporting countries, so they can be low, and a non-reporting country can rank higher than shown or be missing from the list. World totals add both and leave out trade between two non-reporting countries. Figures are in current US dollars; reported imports are mostly valued CIF and exports FOB, and exports include re-exports. The UN Comtrade links show the underlying records; they can also list a few reporters left out here (regional groups and older HS editions).
