Calcined Flint Powder Road Dusting from Germany
Calcined flint powder, produced by heat-treating flint and then grinding, is used for road surface dusting and stabilization. The heat treatment does not alter the mineral structure beyond what is allowed for heading 2517, and the product serves as a powder for road metalling. It falls under tariff item 2517.10.00, which includes flint and heat-treated stone products.

Import Tips
• Verify that the flint powder is not mixed with chemical additives, as that could exclude it from Chapter 25
• Keep records of the heat-treatment process to show it is within the scope of the heading
• Check if the powder is considered a hazardous material for transport, as flint dust may require special handling
