SITCSection 7
U.S. imports of processors and controllers (integrated circuits) (SITC 77642) totaled $3.0B in April 2026, traded with 67 countries.
Importers of Processors and Controllers (Integrated Circuits) paid $10.3M in duties in April 2026 — an effective duty rate of 20% on $51.6M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataSubject to Section 301 tariffs on goods of Chinese origin, processors and controllers are among the most strategically sensitive components in global electronics supply chains, powering everything from consumer devices to industrial automation systems. The SITC heading captures chips that may integrate memories, converters, logic circuits, amplifiers, and clock/timing circuits on a single die — a breadth that can create classification ambiguity when a device combines multiple functions. Importers should confirm whether a given chip's primary function qualifies it here versus under a more specific integrated-circuit heading, as the distinction affects both duty treatment and export-control screening under EAR.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Classification hinges on the chip's principal function. A device marketed and designed primarily to execute instructions or manage system operations generally falls here, even if it incorporates memory or analog blocks. When function is ambiguous, importers typically rely on the manufacturer's datasheet and, if needed, a binding ruling from CBP to lock in the correct heading.
Processors and controllers sourced from China are subject to Section 301 tariffs. Importers should verify the specific list and product exclusion status at the time of entry, as exclusions have been granted, expired, and reinstated on a rolling basis. Consulting a licensed customs broker is advisable given the frequency of updates.
