The other two are twice as expensive as USPS.
I did change the description on the customs form.
The funny thing is that I've sent 4 packages to this same guy over the past month, one is a camshaft that will have rust protectant on it, two cylinder heads, etc. I think they really screwed up, but I have no recourse.
Don't give up yet Brent.
It really sounds like they screwed up...made a mistake...like we all do from time to time.
Be cordial and accepting of the mistake and allow them to help you make things right by reshipping the items (no cost to you because you already paid)
Force them to identify exactly where the issue lies...and when they can not they will be painted into a corner and likely ship the package without issue.
The "dangerous package" claim is fairly arbitrary, especially when you read the dangerous package rules and regualtions you signed for when filling out the original paperwork.
Make them tell you why your aluminum rockers, steel piston rings, and forged pistons are dangerous or hazardous in any manner...They can't because they are not.
Once that has been established, play a little dumb and ask for their assistance in how to best remedy the mistake they made when denying your shipment.
Keep very goot notes on all of this, including names dates and times of everyone you speak to.
Do not let them package your product for you...you will do a better job.
Double check every box and get receipts for everything just in case this shipment gets "lost" on the second try.
Oh, be persistent, but not nagging. They often use a "sorry nothing we can do" as the first tactic in hopes you will simply go away and not be a problem any longer...even if they are 100% at fault and liable for the results.
Lots and lots, and lots of claims are "solved" with this tactic...and it works most of the time.
Proof, receipts, and making them directly show you why you were denied often gets you useful results when you have no issues to begin with because they made a mistake.
Now, if you had a can of spray paint in with the auto parts you are sunk.
Keep us posted because I am curious how this turns out.
