Import Tips
• Ensure the firmware assembly is declared as a part of a word processing machine, not as software media, since it is embedded in a PCA
• If the EPROM chips are presented separately without the PCA, they may be classified as electronic components under heading 85.42
• Document the word processor models this firmware supports to substantiate the classification
