IF someone can ascertain from Customs that the charges you highlight there are all that you'll end up paying, maybe. Otherwise, prepare to get a new orifice torn through your wallet - dealing with Customs is a total PITA. When I got the X1 review unit, despite labels on it that it was a review unit, Customs charged it based on the declared price. Which normally would be "zero" since it was a prototype with "Not for sale" etched on the back, but because DHL had to pay it right then and then neither DHL nor Cusotms wanted to fix it other than DHL shipping it back to the other reviewer who forwarded it. We worked it out with Fiio, but it was extremely frustrating and embarassing on our part for our participation all because Customs didn't bother reading descriptions noted on it.
Regular post/EMS probably wouldn't be any better. I left my school windbreaker/hoodie in LA back in college (2004 I think) and my Dad shipped it back after washing it, lo and behold, Customs was charging me taxes for it. Note that they've already seen the whole jacket and have been told that it's used at that point, so I spread out the Royal Blue hoodie,held it up, and pointed at the white and blue eagle on it - "mukha bang imported 'to?! nagbebenta ba sila ng ganito sa Staples Center o malamang sa may Katipunan (Avenue) ko 'to nabili 'di ba?" If it had an archer on it they might have argued it was a DC comics official product.
Another time my Mom sent me a packet with ten greeting cards, since it was cheaper to send them all to me then I hand them out during Christmas dinner. Customs argued it was "retail quantity" since there were clearly ten in there. I pulled out each of the cards, read the messages, and asked them if they would buy one such card with a hand-written message from my brother to my cousin joking about his shrinking dick (he was obscenely obese), with Dear (name) and Sgd (name) both filled out. I am not sure if it was because I got the point across, or because they were by that point sure that there wasn't any money hidden in the Christmas cards, but I marched out with the cards when none of them answered within ten seconds.
