Analysis

HTS 8541.21.00 covers with a dissipation rate of less than 1 W under heading 8541 (semiconductor devices (for example, diodes, transistors, semiconductor-based…). US Customs collects import statistics for it under 3 ten-digit suffixes, reported in number of items.

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 334413 (Semiconductor and Related Device Manufacturing), an industry of 822 US establishments employing 116,831 people. That concordance is how imports of this line are compared with US output.

The ten-digit suffixes separate unmounted chips, dice and wafers and with an operating frequency not less…. The duty is the same across them; the suffix matters for statistics, licensing and some quotas, and an entry needs all ten digits.
