Analysis
HTS 2835.29.20 covers other: of triammonium under heading 2835 (phosphinates (hypophosphites), phosphonates (phosphites) and phosphates; polyphosphates…).
Within this group the rate runs from duty-free to 4.1%. Compared with 2835.29.51 (other: other), which pays 4.1%, a misclassification either way moves the duty by 2.6 percentage points.
The general duty rate is 1.5% of the customs value, which is in the middle of the rates in chapter 28 (37th percentile of 274 lines with an ad valorem rate). On a shipment valued at $10,000 that is $150 in duty before any Chapter 99 additions or preference claims.
Goods that qualify under GSP, the Australia FTA, the Bahrain FTA, the Chile FTA, the Colombia TPA, and 12 others can enter duty-free instead of paying 1.5%. It is also eligible under GSP, the developing-country programme, which Congress has to renew; check whether GSP is in force on the entry date.
The other lines in the same group are 2835.29.10 (other: of aluminum, duty-free), 2835.29.30 (other: of trisodium, 2.2%) and 2835.29.51 (other: other, 4.1%).
Census statistics map these goods to NAICS 325312 (Phosphatic Fertilizer Manufacturing), an industry of 79 US establishments employing 6,248 people. That concordance is how imports of this line are compared with US output.
