More Specific Codes
This product may fall under a more specific subheading:
Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the board is imported without active electronic components (e.g., as a bare PCB)
This item covers parts and accessories of printed circuit assemblies, including face plates and lock latches, which may apply if the board lacks active elements.
If the board is not a printed circuit assembly but another type of part for ADP machines
This residual item covers other parts and accessories for machines of heading 84.71, which may apply if the board does not meet the definition of a printed circuit assembly.
If the board is imported as part of a complete ADP system
If the board is presented as a unit within a system under subheading 8471.49, it may be classified with the system rather than separately.

Import Tips & Compliance
• Ensure the board is declared as a printed circuit assembly under 8473.30.20, and be ready to provide technical documentation showing it is solely or principally for use with ADP machines of heading 84.71
• Verify whether the board qualifies for duty-free treatment under a free trade agreement, as rates may vary by origin
• If the board is imported with other components, confirm whether it should be classified separately or as part of a system under subheading 8471.49
