Import Tips
• Include coating specifications and cleanroom compatibility certs to avoid generic steel part classification
• Use invoices specifying semiconductor statistical note applications for accurate duty assessment
• Prevent pitfalls by separating from full grinder machines to maintain 8482 classification
