Import Tips
• Provide engineering drawings showing wafer boat compatibility to substantiate 7020.00.30 classification
• Declare exact dimensions and tolerances; undersized holders may face scrutiny as general labware
• Include semiconductor fab end-user letters to prevent misclassification as generic quartzware
