Import Tips
• Include calibration certificates or recorder manuals showing the exact scale matches to substantiate use in self-recording apparatus
• Watch for misdeclaration as general printed paper; emphasize the functional printing via detailed invoices and photos
• Ensure sheets are not perforated cards, as those may fall under general 4823 provisions if not for self-recording
