Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If the PCA is sold with face plates or lock latches as a set
Parts and accessories of printed circuit assemblies, including face plates and lock latches, are classified separately.
If the PCA is not a printed circuit assembly but another part
Other parts and accessories of machines of heading 84.71 are classified under this residual item.
If the PCA is presented as part of a complete automatic data processing system
Systems comprising a central processing unit and input/output units are classified under this heading.
