Import Tips
• Specify block size (width x length x height) and preload class in commercial invoices for accurate duty assessment
• Include material certificates confirming bearing steel (e.g
• SUJ2) construction
• For cleanroom versions, document low-particle grease to support semiconductor end-use claims
