HS Code for Mask aligner
Mask aligners are classified under HS code 8486.40. This code is part of a specialized heading created to consolidate machinery used in the semiconductor industry. Heading 8486 covers machines and apparatus used solely or principally for the manufacture of semiconductor boules, wafers, devices, integrated circuits, or flat panel displays. Subheading 8486.40 specifically addresses machines and apparatus for the manufacture or repair of masks and reticles, as well as lifting and handling equipment. Mask aligners are critical in the photolithography process, ensuring that the photomask is perfectly positioned over the silicon wafer. Because their primary and sole function is within the semiconductor fabrication line, they are excluded from general optical or photographic headings and placed within this high-tech machinery category. The classification is driven by the application of the machine rather than its individual mechanical components.

Common Misclassification
Mask aligners are sometimes misclassified under 8456.11 (laser machine tools) or 9010.50 (other apparatus for photographic laboratories). However, Note 11 to Chapter 84 mandates that machines meeting the description of heading 8486 must be classified there and nowhere else in the nomenclature.
