HS-4 · Heading
3810 — Metal-pickling preparations; fluxes etc for soldering, brazing; welding powders, pastes of metal and other materials; preparations used as cores or coatings for welding electrodes or rods
Chapter 38: Miscellaneous chemical products
Plain-language overview
Use HS-4 3810 when importing or exporting metal-pickling preparations, soldering pastes, or welding powders. For example, if you’re shipping a container of flux for soldering applications, this code is relevant.
When deciding between HS-6 381010 and HS-6 381090, consider the composition of your product. If it’s a metal-based powder or paste specifically for soldering or welding, use 381010. If it’s a flux or auxiliary preparation not primarily made of metal, go with 381090.
The distinction between these two subheadings is crucial. 381010 covers products that are predominantly metal-based, while 381090 includes non-metallic fluxes and coatings for welding electrodes. Ensure you classify your goods accurately to avoid customs issues.
