HTS 8531.90.30 covers printed circuit assemblies: other under heading 8531 (electric sound or visual signaling apparatus (for example, bells, sirens, indicator…).
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.
Goods classified here enter the United States duty-free at the general (normal trade relations) rate, as do about 58% of the 624 tariff lines in chapter 85. Free here means free of the base duty only: origin-specific Chapter 99 duties such as Section 301 can still be owed.
The other lines in the same group are 8531.90.15 (of the panels of subheading 8531.20, duty-free), 8531.90.75 (of the panels of subheading 8531.20, duty-free) and 8531.90.90 (other: other, duty-free).
Census statistics map these goods to NAICS 334418 (Printed Circuit Assembly (Electronic Assembly) Manufacturing), an industry of 861 US establishments employing 49,932 people. That is the industry code a US manufacturer of the same product would normally use.
All 3 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.
