About HS Code 810991
This code covers processed forms of zirconium, other than unwrought or waste/scrap, that maintain a very low hafnium content (less than 1 part hafnium to 500 parts zirconium). This includes semi-finished products like bars, rods, plates, sheets, tubes, and wires, specifically manufactured for nuclear applications where hafnium's neutron absorption is undesirable. These materials are critical components for nuclear reactors, such as fuel cladding and structural elements. The trade involves highly specialized manufacturers and suppliers, often operating under strict international regulations and quality standards. Key importers and exporters are nations with advanced nuclear energy programs or those supplying components to such programs. The high value and strategic importance of these materials necessitate rigorous tracking and certification throughout the supply chain.
Products Under This Code
Nuclear-grade zirconium bars, Zircaloy tubes, Low-hafnium zirconium sheets, Zirconium alloy rods (nuclear), Zirconium wire (low hafnium)
Real World Examples
Zircaloy-4 fuel cladding tubes, Nuclear reactor core components, Zirconium alloy control rods
Common Misclassification
This code is distinct from 810999 due to its low hafnium content, and from 810921 by being in a processed form (not unwrought powder). It can be confused with finished articles of zirconium in Chapter 84 or 85 if the item is a complete functional part.
Industry
This code belongs to the Metals & Metal Products industry.
Trade Overview
The United States, Russia, France, and China are key players in the trade of these specialized nuclear-grade zirconium products.
