2845.40.00

Analysis

HTS 2845.40.00 covers isotopes other than those of heading 2844; compounds, inorganic or organic, of such isotopes, whether or not chemically defined: helium-3 under heading 2845 (isotopes other than those of heading 2844; compounds, inorganic or organic, of such…).

There is no general-rate duty on this line, which puts it with roughly 29% of the 274 tariff lines in chapter 28 that are also free. Chapter 99 measures such as Section 301 or 232 can still apply on top, depending on where the goods come from.

Goods from countries without normal trade relations pay the column 2 rate of 25% instead of nothing, so origin decides between free entry and a 25% duty.

The other lines in the same group are 2845.10.00 (heavy water (Deuterium oxide), duty-free), 2845.20.00 (boron enriched in boron-10 and its compounds, duty-free), 2845.30.00 (lithium enriched in lithium-6 and its compounds, duty-free) and 2845.90.01 (isotopes other than those of heading 2844; compounds…, duty-free).

Census statistics map these goods to NAICS 325180 (Other Basic Inorganic Chemical Manufacturing), an industry of 705 US establishments employing 41,447 people, the industry a domestic producer of these goods reports under.
