Import Tips

Verify the board's function via technical specs to confirm it doesn't qualify for more specific headings like 8542 for ICs

Include detailed BOM and circuit diagrams in documentation to avoid misclassification as general PCBs under 8534

Check for RoHS compliance and provide certificates to prevent customs holds on electronic assemblies
