HTS heading 8104 groups magnesium and goods made from magnesium. It can include unwrought magnesium metal, magnesium products in worked forms, and magnesium waste or scrap. The heading is a broad product category, not the final tariff classification for an import entry.
To reach the correct 8-digit HTSUS code, first identify the product’s condition and form—such as primary metal, a worked article, or waste and scrap—then follow the applicable subheading descriptions and any relevant section, chapter, or heading notes. The detailed code may depend on the material, physical form, processing, or intended product type. Confirm the full code against the current official HTSUS and, when the facts are unclear, obtain customs-broker or classification-professional advice.
What to check
- Confirm that magnesium is the material covered and that another heading does not describe the finished product more specifically.
- Document the product’s form, dimensions, processing, alloy or purity information, and whether it is waste or scrap.
- Read the subheading text and all applicable legal notes; do not choose an 8-digit code from a product name alone.
- Use commercial invoices, specifications, drawings, photographs, and supplier records to support the classification.
- Check the current HTSUS and seek a binding ruling or qualified customs advice when competing classifications are plausible.
HTS heading 8104 summary
Magnesium and articles thereof is a 4-digit product category containing 5 published product-code lines in this snapshot. A heading does not carry one universal duty rate; classification must be narrowed to the line matching the product facts.
How to find your code in this category
A heading is a product category. To get the exact duty, narrow from this 4-digit heading to a sub-category (usually by material), then open the 8-digit code that matches your product.
Open any code in the tables below to see its exact duty rate, a duty calculator (enter your shipment value → estimated duty and landed cost), the rate-change history chart, and the country-by-country breakdown (including Section 301/232 add-on duties).
Why you have to click in: a single category can contain products with very different duties. The rate depends on the specific product — its material and construction — and on the country of origin, and those only get pinned down at the 8-digit code level. That is why this page points you to codes instead of showing one rate for the whole category.
