HS Code for Wafer manufacturing equipment

Wafer manufacturing equipment is classified under HS code 8486.10 because it encompasses machines and apparatus used solely or principally for the manufacture of semiconductor boules or wafers. This classification is governed by Note 9 to Chapter 84, which provides a specific heading for semiconductor manufacturing equipment, taking precedence over other machinery headings in the Harmonized System. The equipment classified here is essential for the initial stages of semiconductor production, specifically the growth of monocrystalline boules and the subsequent slicing, grinding, and polishing of these boules into thin wafers. These wafers serve as the substrate for integrated circuits. The classification depends on the primary function of the machine; it must be dedicated to the production of the raw wafer itself rather than the subsequent fabrication of electronic components on that wafer. This distinction is critical for customs compliance, as the machinery involved often utilizes high-precision mechanical, thermal, and chemical processes unique to the semiconductor industry.

Products Included

• Czochralski crystal pullers for growing silicon boules
• Bridgman-Stockbarger furnaces for crystal growth
• Internal diameter (ID) saws and wire saws for wafer slicing
• Edge grinding machines for wafer profiling
• Chemical-mechanical polishing (CMP) equipment for wafer smoothing
• Wafer lapping machines

Common Misclassification

This code is frequently confused with HS code 8486.20, which covers machines for the manufacture of semiconductor devices or electronic integrated circuits. While 8486.10 is for making the wafer, 8486.20 is for processing that wafer into a chip. Additionally, general-purpose machine tools for working stone or glass under heading 8464 are sometimes incorrectly used, but Note 9 to Chapter 84 mandates the use of 8486 for semiconductor-specific applications.

FAQ

What is the HS code for Wafer manufacturing equipment?

The primary HS code is 8486.10, which specifically covers apparatus for the manufacture of semiconductor boules or wafers.

Does this code include equipment for flat panel displays?

No, equipment for the manufacture of flat panel displays is classified under HS code 8486.30, not 8486.10.
