Import Tips
• Verify the PCA is documented as suitable for both 8471 (EDP) and 8473 (semiconductor) machines to qualify under this subheading
• Include engineering specs proving multi-machine compatibility; misclassification to single-use parts risks reclassification
• Ensure RoHS compliance and static protection packaging to avoid customs holds on semiconductor-related imports
