Analysis
HTS 3808.92.24 covers maneb; Zineb; Mancozeb; and Metiram under heading 3808 (insecticides, rodenticides, fungicides, herbicides, antisprouting products and…).
Within this group the rate runs from duty-free to 6.5%. Compared with 3808.92.15 (containing any aromatic or modified aromatic fungicide: other), which pays 6.5%, a misclassification either way moves the duty by 6.5 percentage points.
The normal trade relations rate here is zero, shared by about 25% of the 179 tariff lines in chapter 38, a useful check when a neighbouring dutiable line is a candidate. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
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 325320 (Pesticide and Other Agricultural Chemical Manufacturing), an industry of 252 US establishments employing 12,680 people. That concordance is how imports of this line are compared with US output.
Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
