2530.90

Analysis

Subheading 2530.90 covers other, within heading 2530. The first six digits are shared by every country that uses the Harmonized System, so this part of the code is the same in the US, UK and EU schedules; the 3 US tariff lines below it are national.

2 of its 3 lines with a percentage rate are duty-free at the general rate (67%) and 1 are dutiable, from duty-free up to 2.9%. The median line pays duty-free.

The US splits it as follows: 2530.90.10 for natural cryolite; natural chiolite (duty-free), 2530.90.20 for natural micaceous iron oxides (2.9%) and 2530.90.80 for other: other (duty-free).

By Census's concordance, most of its statistical lines are made by Other Nonmetallic Mineral Mining and Quarrying (21239). Those are the NAICS industries a US producer of these goods would report under.

Goods only reach 2530.90 once they fall within heading 2530 (mineral substances not elsewhere specified or included). Under General Rule 6, subheadings are then compared only with others at the same level, so a product is matched against its siblings, not against lines elsewhere in the chapter.
