In my case, I had three date coded oem motors and my value was higher. I was told that if I declared them at true value, then the customs guys could determine that I was trying to hide a sale instead of services and charge Canadian import fees. I would in turn have to pay that fee as well. Did not seem to be a chance I was willing to take. Not worried about the restorers loosing the parts near as much as the shipper. I shipped a single motor to Jules and had no problem.
