Import Tips
• Include vacuum specifications and cleanroom particle emission test results in entry documents
• Document integration with crystal grinders or polishers to support semiconductor-specific classification
• Beware of reclassification as Chapter 84 parts if imported unassembled; provide assembly diagrams
