Analysis
HTS 2845.90.01 covers isotopes other than those of heading 2844; compounds, inorganic or organic, of such isotopes, whether or not chemically defined: other under heading 2845 (isotopes other than those of heading 2844; compounds, inorganic or organic, of such…).
The normal trade relations rate here is zero, shared by about 29% of the 274 tariff lines in chapter 28, a useful check when a neighbouring dutiable line is a candidate. 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 2845.40.00 (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. That concordance is how imports of this line are compared with US output.
