Analysis
HTS 8479.89.10 covers air humidifiers or dehumidifiers under heading 8479 (machines and mechanical appliances having individual functions, not specified or included…).
Within this group the rate runs from duty-free to 2.8%. Compared with 8479.89.65 (electromechanical appliances with self-contained electric motor: other), which pays 2.8%, a misclassification either way moves the duty by 2.8 percentage points.
Goods from countries without normal trade relations pay the column 2 rate of 40% instead of nothing, so origin decides between free entry and a 40% duty.
The normal trade relations rate here is zero, shared by about 61% of the 823 tariff lines in chapter 84, 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.
Census statistics map these goods to NAICS 333415 (Air-Conditioning and Warm Air Heating Equipment and Commercial and Industrial Refrigeration Equipment Manufacturing), an industry of 852 US establishments employing 101,617 people. That concordance is how imports of this line are compared with US output.
