Thanks for sharing your experience .
I don’t understand why you would have had to pay 20%—was it an exotic?
I will share a little more on my experience .
I have had a few things shipped — canvas bags, leather bags , wooden jewelry box, crystal glassware, art . What I have discovered is duty is computed by the carrier who brings it into the country . The carrier determines that duty based on the description provided by the shipper - which determines the items category - and “The US Harmonzied Tariff Schedule “ (HTS) - which provides the duty %.
hts.usitc.gov
I have spent time going through the HTS — it is a huge document that covers duty rates for every category you can think of.
Sometimes the shipper doesn’t provide a good enough description for the carrier to determine the duty % from the HTS and additional information has to be requested from the shipper. For example in my case, additional information was requested from the shipper about my wooden jewelry box— more detail was required on the types of wood and the origin of the different woods. Unfortunately , the shipper did not answer quickly enough so the carrier sent the box back to the shipper and it took weeks to sort things out.
Sometimes the carrier makes a mistake in their calculation. When I shipped crystal glassware it wasn’t described well in the shipper’s description and was classified in a category of regular glass with a rate of over 20%. I went through the HTS and found the correct category , which was around 3%. After the carrier confirmed the correct description of the type of glass with the shipper, the rate was changed to the correct 3%.
It seems to me there is a lot of opportunity for error. Both in the shipper’s description (typically not enough detail ) and the carrier’s calculation of tariff . You can ask the carrier to provide information on their calculation if you have any questions.
When I had a shipment of only handbags, both leather and canvas, they have always been taxed at 9%.
