I would not jump to conclusions. A large company the exports all the time is not going to put the wrong value on a shipment and risk their business.
Screw the large company exporting, they are causing accounting and customs problems for the customers who are receiving the packages.
I declared an expense of USD $22,400 when I bought the equipment.
I now have an IM4 document proving the import of the equipment at CAD $2435.20. I have a virtual VAT invoice (due to ET license we never pay VAT at import) of EUR 382.70 that does not match my original purchase.
My beancounter is going to love me when I submit the papers in 2 days for M01 2014...
For Belgian customs it's not such a problem they are lax (flexible?), but for example German customs is known to flag and hold cases like this where the declared value does not match the published (on a website) value they google.
