gotcha ben..i wasn't trying to make a case for you shipping chem kits to canada, so you know the liability by the way for a mislabeled shipment, item marked as a gift when it is not, lost shipment, item marked at a clearly unreasonable value is the shippers, even if they have proof it was requested to be sent inappropriately by the receiver. the shipper has to make any inquiries and claims to usps.the receiver can try, but unless you get a real mr. friendly at usps, you will get the "usps manual" line and correctly so i think, that the shipper has to make the contact with usps. in most cases unless there is a really flagrant abuse, customs will simply seize the item and end of story. but i believe fines and imprisonment are possibilities. years ago when i started buying, selling and trading computer parts, i didn't know any better and people marked items as gifts all the time. these days, not worth it. the fees just aren't high enough from canada post to take the risk and if it's a low value item, the fees are going to be dirt cheap or nonexistent for duties (under 60 canadian value, zero duties)
