8471.70.10

Analysis

HTS 8471.70.10 covers without read-write unit assembled therein; read-write units entered separately under heading 8471 (automatic data processing machines and units thereof; magnetic or optical readers…).

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 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 334112 (Computer Storage Device Manufacturing), an industry of 61 US establishments employing 7,221 people. That concordance is how imports of this line are compared with US output.

All 6 neighbouring lines carry the same duty-free rate, so a borderline choice between them changes the statistics reported, not the duty paid.

Every edition we compared, from Jan 2023 to Oct 2026 (Rev. 22), shows the same general rate of Free.
