The CSN checklist: what customs refuses (red), what's worth a look (amber), each a jump

In this film

• Red: the values customs has refused on record — Sign & upload will not send a filing with any of them
• Amber: worth a look, never a refusal — values customs has refused and accepted too
• Three red ones fixed from the list: a master bill flagged H (056), a notify party coded IEC instead of PAN (045), a UN number with a trailing space (032)
• Nothing red left — only amber
• Essentials (just what customs requires, plus anything filled) and Advanced (every field of the message)
• Sign & upload runs the same checks again first
