Import Tips
• Verify the PCA is exclusively for microphones of 8518.10.40 via schematics and manufacturer specs to avoid misclassification
• Include bills of materials (BOM) and circuit diagrams in documentation to prove compatibility with specified subheadings
• Watch for overclassification as complete amplifiers (8518.40); ensure no standalone enclosure or power supply
