Analysis
HTS 3105.60.00 covers mineral or chemical fertilizers containing the two fertilizing elements phosphorus and potassium under heading 3105 (mineral or chemical fertilizers containing two or three of the fertilizing elements…).
There is no general-rate duty on this line, which puts it with roughly 100% of the 24 tariff lines in chapter 31 that are also free. 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.
Census statistics map these goods to NAICS 325312 (Phosphatic Fertilizer Manufacturing), an industry of 79 US establishments employing 6,248 people, the industry a domestic producer of these goods reports under.
All 7 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
The general rate of Free has not changed in any edition of the schedule since Jan 2023.
