Analysis
HTS 2804.70.00 covers hydrogen, rare gases and other nonmetals: phosphorus under heading 2804 (hydrogen, rare gases and other nonmetals).
Within this group the rate runs from duty-free to 5.5%. Compared with 2804.69.50 (other: other), which pays 5.5%, a misclassification either way moves the duty by 5.5 percentage points.
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.
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.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
