About heading 2805

Alkali or alkaline-earth metals; rare-earth metals, scandium and yttrium, whether or not intermixed or interalloyed; mercury

Heading 2805 covers the elemental metals of the alkali and alkaline-earth groups, the rare-earth metals plus scandium and yttrium, and mercury. The lines split first by metal family, then by the specific element, so sodium, calcium, strontium, barium and lithium each have their own line, and rare-earth metals split between individual unmixed elements and intermixed or interalloyed forms.

Frequently asked questions

What is the HTS code for sodium metal?

Sodium metal is classified under 2805.11.00.00. The general (MFN) duty rate for that line is 5.3%.

What is the duty on cerium metal?

Unmixed cerium metal falls under 2805.30.00.10. The general (MFN) duty rate is 5%.

How do I classify lithium metal?

Lithium is an alkali metal not named in the sodium or calcium lines, so it goes under 2805.19.90.10, which carries a general (MFN) rate of 5.5%. Neodymium metal, by contrast, is listed at 2805.30.00.20 at 5%.
