Rebuilt Disco DFG8340 Wafer Lapping System
Rebuilt numerically controlled lapping system for semiconductor wafers, achieving sub-micron flatness on silicon substrates using diamond abrasives. Falls under HTS 8460.40.40.10 for rebuilt NC lapping machines finishing metal surfaces.
Import Duty Rates by Country of Origin
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If dedicated to semiconductor wafer processing
Chapter statistical notes cover wafer preparation lappers under semiconductor manufacturing machines.
If not numerically controlled
NC is required for .40 subheading; conventional lappers use .20 or .60.
If primarily for metrology/testing rather than finishing
Precision measuring lappers may shift to optical/instrument chapters.
Not sure which classification is right?
The Tariff Assistant works through the GRI rules on your specific product to reach the right HTS code — and can price the duty on it in the same conversation.
Import Tips & Compliance
• Submit OEM rebuild certificates and before/after specs to Customs for used/rebuilt verification
• Label as semiconductor-specific if applicable, but primary classification remains lapping function
• Check for dual-use export controls on precision wafer equipment
