Plain-language overview
Use HS-6 381090 when importing or exporting fluxes and auxiliary preparations for soldering, brazing, or welding. An example would be a shipment of flux paste used in metalworking processes.
This code specifically covers fluxes and other preparations that assist in soldering and welding, distinguishing it from HS-6 381091, which is for fluxes that are specifically designed for use in welding electrodes.
If you're dealing with preparations used as cores or coatings for welding rods, this HS-6 code is your go-to. It's important to note that products classified under this code may vary in composition and intended use, affecting their classification.
When considering HS-6 381090, think about the specific application of the product. For instance, a flux that helps in the brazing of metals would fit here, while a different type of soldering paste might fall under another code.
