8504.50.40

Analysis

HTS 8504.50.40 covers for power supplies for automatic data processing machines or units thereof of heading 8471; power supplies for goods of subheading 8443.31 or 8443.32; power… under heading 8504 (electrical transformers, static converters (for example, rectifiers) and inductors; parts…).

Within this group the rate runs from duty-free to 6.6%. Compared with 8504.31.40 (having a power handling capacity less than 1 kVA), which pays 6.6%, a misclassification either way moves the duty by 6.6 percentage points.

Goods from countries without normal trade relations pay the column 2 rate of 35% instead of nothing, so origin decides between free entry and a 35% duty.

The normal trade relations rate here is zero, shared by about 58% of the 624 tariff lines in chapter 85, 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.

Census statistics map these goods to NAICS 334416 (Capacitor, Resistor, Coil, Transformer, and Other Inductor Manufacturing), an industry of 322 US establishments employing 15,225 people. That concordance is how imports of this line are compared with US output.
