HS-4 · Heading
7406 — Copper; powders and flakes
Chapter 74: Copper and articles thereof
Plain-language overview
Use HS-4 7406 when importing or exporting copper powders and flakes. For instance, if you're shipping a container of fine copper powder used in electronics manufacturing, this heading is relevant. It covers both non-lamellar and lamellar structures of copper powders.
When deciding between HS-6 740610 and HS-6 740620, consider the structure of the copper powder. If your product consists of non-lamellar particles, you should classify it under 740610. Conversely, if it’s a flake form or has a lamellar structure, opt for 740620.
The distinction between these two subheadings is crucial for compliance and tariff purposes. Non-lamellar copper powders are often used in applications requiring uniform particle size, while lamellar flakes are typically used in coatings and conductive materials. Ensure your product matches the description before filing.
