Plain-language overview
Use HS-6 790390 when importing or exporting zinc powders and flakes. This code specifically covers zinc in powder or flake form, commonly used in coatings, batteries, and various industrial applications. For example, a shipment of zinc powder for galvanizing steel would fall under this classification.
This HS-6 line distinguishes itself from HS-6 790391, which covers zinc dust. While both are forms of zinc, dust is typically finer and used in different applications, such as in chemical reactions or as a pigment. Knowing the difference is crucial for proper classification.
The 790390 code also contrasts with HS-6 790394, which pertains to zinc flakes. Flakes may be larger and used in applications like surface coatings or as additives in plastics. Understanding these nuances helps ensure compliance with customs regulations.
When classifying zinc products, consider the physical form and intended use. Accurate classification not only affects duty rates but also compliance with safety regulations in your destination country.
