View full HS code details

Wafer inspection systems are classified under HS code 9031.41. This classification is highly specific and is governed by the legal notes of Chapter 90, which covers optical, measuring, and checking instruments. Heading 9031 is a residual heading for measuring or checking instruments, appliances, and machines not specified or included elsewhere in the chapter. Subheading 9031.41 is dedicated to optical instruments and appliances for inspecting semiconductor wafers or devices, or for inspecting photomasks or reticles used in semiconductor manufacturing. These systems are essential in the fabrication process to detect microscopic defects, contamination, or pattern irregularities. The 'optical' designation means the system uses light (including ultraviolet or infrared) and lenses to perform the inspection. This classification is preferred over more general headings because of the specific end-use in the semiconductor industry. It is important to note that this code covers the complete system used for inspection, which often includes complex software and robotic handling components integrated into the optical unit.

Products Included

  • Automated Optical Inspection (AOI) systems for wafers
  • Photomask inspection equipment
  • Reticle inspection systems
  • Defect review stations (optical)
  • Critical Dimension (CD) measurement tools (optical)
  • Wafer surface scanners

Common Misclassification

Wafer inspection systems are often confused with HS code 9012.10, which covers microscopes other than optical microscopes (such as electron microscopes). If the inspection system uses an electron beam rather than light, 9012.10 is the correct code. Another common error is 8486.20, which covers machines and apparatus for the manufacture of semiconductor devices. While inspection is part of the manufacturing environment, heading 9031 is more specific for the 'checking' function. Additionally, general-purpose optical inspection tools not specifically designed for semiconductors would fall under 9031.49.

FAQ

What is the HS code for a wafer inspection system?

The specific HS code for optical wafer inspection systems is 9031.41.

Does this code include electron-beam inspection tools?

No, electron-beam (e-beam) tools are generally classified under 9012.10 because they are not 'optical' instruments in the traditional sense of using light.
