U.S. imports of Processors & Controllers — Electronic Integrated Circuits (HS 854231) totaled $3.2B in August 2026, imported from 74 countries.
Importers of Processors & Controllers — Electronic Integrated Circuits paid $6.1M in duties in August 2026, an average duty rate of 0.23% — duty actually collected as a share of the imports that cleared customs, not the published tariff schedule.
Last updated: August 2026 dataAt the center of the global semiconductor trade, this heading covers CPUs (8542310045), GPUs (8542310040), DSPs (8542310035), microcontrollers by bit-width (8-bit through other), FPGAs (8542310060), CPLDs (8542310055), and system-on-chip devices (8542310070) — a lineup that spans consumer electronics, automotive, industrial automation, and AI computing. Taiwan is the leading US supplier, a reflection of TSMC's dominant foundry position, with Malaysia and Israel also significant sources. Export-control classification under the Export Administration Regulations (EAR) is a parallel compliance obligation for many advanced processors, particularly high-performance GPUs and AI accelerators, which may require export licenses for certain destinations. Section 301 tariffs apply to goods of Chinese origin within this heading.

FPGAs (8542310060) and CPLDs (8542310055) are programmable logic devices whose internal logic is configured by the end user after manufacture, distinguishing them from fixed-function processors and microcontrollers. The US tariff schedule provides dedicated lines for each, so importers must identify the device architecture — not just its application — to select the correct 10-digit line. Devices marketed as 'adaptive compute' or 'SoC FPGAs' may require additional analysis to determine whether 8542310070 (SoC) or 8542310060 (FPGA) is more appropriate.
Yes. Many high-performance GPUs and AI accelerators classified under 8542310040 are subject to Export Administration Regulations controls based on performance thresholds (e.g., aggregate compute capability). BIS has issued rules restricting exports and re-exports of advanced chips to certain countries. Importers who subsequently re-export or transfer these devices must assess EAR license requirements independently of the import duty classification.
