HTS Chapter 79 covers zinc and certain zinc products. Representative heading 7901 covers unwrought zinc, while heading 7903 covers zinc dust, powders, and flakes. Classification can depend on the zinc’s form, condition, processing, alloy content, and whether the product is a distinct article rather than basic zinc material.
The HTS is organized from broad to specific: chapter, heading, subheading, and the complete 10-digit statistical code. Start in Chapter 79, read the heading descriptions and legal notes, then compare the product with the subheadings under the most relevant heading. Confirm the full 10-digit code using the product’s composition, physical form, manufacturing process, and any applicable exclusions or additional provisions. A customs broker or other qualified classification professional may be needed for difficult products.
What to check
- Verify the zinc content, alloy composition, physical form, and degree of processing from specifications, laboratory data, or supplier documents.
- Distinguish basic unwrought zinc, dust, powder, or flakes from finished zinc articles that may be classified elsewhere in the HTS.
- Read the Chapter 79 notes, heading text, subheading notes, and relevant Section XV provisions for definitions and exclusions.
- Check whether the product is excluded from Chapter 79 because another chapter or heading specifically describes it.
- Review the current HTS and any applicable Chapter 99 provisions, trade remedies, or origin-based measures separately from the Chapter 79 classification.
How to use this chapter
A chapter is the first classification level, not a duty rate. Choose the heading that describes the product, narrow by material, construction, use, or other legal distinctions, and verify the final line against the official HTS notes.
