HS Code for Semiconductor metrology
Semiconductor metrology equipment is classified under HS code 903141. This classification falls within Chapter 90, which covers optical, measuring, checking, and precision instruments. Heading 9031 is a residual heading for measuring or checking instruments, appliances, and machines not specified elsewhere in Chapter 90. Subheading 903141 is highly specialized, covering optical instruments and appliances specifically designed for inspecting semiconductor wafers or devices, or for inspecting the photomasks or reticles used in the manufacturing process. The classification is determined by the optical nature of the measurement or inspection process. These tools use light, lasers, or other optical systems to detect microscopic defects, measure film thickness, or verify circuit patterns. Because these instruments are essential for the quality control and yield management of semiconductor fabrication, they are distinguished from general-purpose measuring tools by their specific application and high precision.
Products Included
- Optical wafer inspection systems
- Photomask inspection equipment
- Reticle inspection tools
- Critical dimension (CD) metrology tools
- Overlay metrology systems
Common Misclassification
Semiconductor metrology tools are often confused with HS code 8486, which covers machines and apparatus used solely or principally for the manufacture of semiconductor devices. While metrology tools are used in the factory, heading 8486 generally excludes measuring and checking instruments of Chapter 90. Another common misclassification is HS code 9030, which covers instruments for measuring or checking electrical quantities. If the tool measures electrical properties (like voltage or resistance) rather than using optical methods to inspect physical structures, it may fall under 9030.82.
FAQ
What is the HS code for semiconductor metrology?
The primary HS code for optical semiconductor metrology and inspection equipment is 903141.
Is electron beam inspection included here?
No, electron beam (e-beam) inspection tools are typically classified under HS code 903180 or 8486, as they do not use optical light in the traditional sense defined by the 903141 subheading.
