NAICSSector 33
U.S. imports of semiconductors & related devices (NAICS 334413) totaled $5.9B in July 2026, traded with 120 countries.
Importers of Semiconductors & Related Devices paid $103.3M in duties in July 2026 — an effective duty rate of 14% on $761.8M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: July 2026 dataIntegrated circuits, transistors, diodes, and photovoltaic cells — the active semiconductor devices grouped under NAICS 334413 — are among the most trade-policy-sensitive components in global commerce, subject to Section 301 tariffs on Chinese-origin goods and increasingly scrutinized under export-control and foreign-investment review frameworks. Classification precision matters enormously here: a memory chip, a microprocessor, and a power transistor each fall under different HTS headings with distinct duty treatment. Leading suppliers include economies with advanced fab capacity, and the concentration of advanced-node fabrication in a small number of facilities worldwide creates supply-chain resilience concerns that directly affect procurement strategy.

Microprocessors and microcontrollers occupy different HTS subheadings under Chapter 85. A microprocessor is generally a central processing unit without integrated memory or peripherals, while a microcontroller integrates CPU, memory, and I/O on a single die. Misclassifying one as the other can result in an incorrect duty rate and potential CBP penalties; the manufacturer's datasheet and functional description are the primary evidence for the correct determination.
Yes — while export controls (EAR/ITAR) primarily govern outbound shipments, importers of advanced semiconductors should be aware that re-export restrictions and end-use certifications may be required by foreign suppliers as a condition of sale. Additionally, CBP and BIS coordinate on import transactions involving controlled technology, so importers acting as intermediaries in global semiconductor supply chains should conduct end-use screening.
