Analysis
HTS 3104.20.00 covers potassium chloride under heading 3104 (mineral or chemical fertilizers, potassic). US Customs collects import statistics for it under 2 ten-digit suffixes, reported in metric tons.
For statistics it divides in two: 3104.20.00.10 for containing not more than 62 percent by weight of potassium… and 3104.20.00.50 for containing more than 62 percent by weight of potassium…. Both pay the same duty; the suffix records which kind was imported.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 100% of the 24 tariff lines in chapter 31. Duty-free at the general rate does not rule out additional duties under Chapter 99, such as Section 301 or Section 232 measures, which depend on the country of origin.
The other lines in the same group are 3104.30.00 (mineral or chemical fertilizers, potassic: potassium sulfate, duty-free) and 3104.90.01 (mineral or chemical fertilizers, potassic: other, duty-free).
Census statistics map these goods to NAICS 325312 (Phosphatic Fertilizer Manufacturing), an industry of 79 US establishments employing 6,248 people. That is the industry code a US manufacturer of the same product would normally use.
