Analysis
HTS 2826.12.00 covers fluorides: of aluminum under heading 2826 (fluorides; fluorosilicates, fluoroaluminates and other complex fluorine salts).
Within this group the rate runs from duty-free to 4.1%. Compared with 2826.90.10 (fluorosilicates of sodium or of potassium), which pays 4.1%, a misclassification either way moves the duty by 4.1 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.
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.
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.
