8533.90.40

Analysis

HTS 8533.90.40 covers for the goods of subheading 8533.40, of ceramic or metallic materials, electrically or mechanically reactive to changes in temperature under heading 8533 (electrical resistors (including rheostats and potentiometers), other than heating…).

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.

There is no general-rate duty on this line, which puts it with roughly 58% of the 624 tariff lines in chapter 85 that are also free. 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, the industry a domestic producer of these goods reports under.

All 8 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.
