U.S. imports of instruments and apparatus for measuring or checking semiconductor wafers and devices (HS 903082) totaled $51.9M in April 2026, traded with 33 countries.
Importers of Instruments and Apparatus for Measuring or Checking Semiconductor Wafers and Devices paid $4.5M in duties in April 2026 — an effective duty rate of 10% on $44.0M in dutiable value, based on actual customs collections rather than the published tariff schedule.
Last updated: April 2026 dataSemiconductor wafer and device metrology equipment — covering parametric testers, wafer probers, CD-SEM systems, and electrical characterization tools used in integrated circuit fabrication and quality control — is consolidated under a single US tariff line (9030820000). These instruments are critical capital goods for the semiconductor supply chain, and their classification is sensitive to export-control regimes as well as standard customs rules. Malaysia, Japan, and Taiwan are the leading US import sources, reflecting the geographic concentration of both semiconductor manufacturing and precision equipment production in Asia. Given the strategic nature of this equipment, importers should also assess Export Administration Regulations (EAR) applicability on re-export.
AI-written summary of the official U.S. Census Bureau trade figures on this page — verify before relying on it.
Yes. Many advanced semiconductor metrology tools are controlled under the Export Administration Regulations (EAR) and may appear on the Commerce Control List. While EAR primarily governs exports and re-exports, importers should verify that the equipment's origin and specifications do not trigger re-export license requirements before onward transfer or use in certain applications.
If the system is designed and marketed specifically for semiconductor wafer or device characterization, it belongs under this heading regardless of whether it also performs general electrical measurements. The semiconductor-specific design intent — evidenced by wafer-handling mechanics, probe card interfaces, or fab-environment specifications — is the controlling factor. A general electrical tester that can be adapted to probe wafers would more likely fall under a different subheading.
