Hi Russ, thanks for the review. Was it the regulator or tamper that had some distortion? I would like to look into this further.
And yes, unfortunately, we have switched to UPS for international shipping due to package claims with USPS, which costs more, but has a shorter shipment time.
By law, we are required to state on the package, regardless of the shipper, the value of the product inside. So duty/tariff taxes should be the same regardless of carrier. Sorry we can't help with this one!
