I receive envelopes from the US. Some contain things like credit card replacements, other contain screener DVDs from the studios I used to work for. They come by FedEx, DHL, UPS and snail mail. Each and every one is opened by aduanas. Fine. No complaint. I understand that they think I may have developed the technology to shrink a kilo of cocaine into a DVD envelope, not box, envelope. Can someone please explain why I get charged duty on anything and everything delivered by UPS. Not FedEx, not DHL, not the Post Office. Only UPS. This morning I received new ATM cards from my New York bank. I had to pay 55 pesos aduanas duty for a fricken envelope with 2 plastic cards inside. The operator at UPS was totally unhelpful and couldn't (wouldn't) find anyone for me to speak with. With 80 or so envelopes arriving every October to January, it is mildly annoying to fork over 3 to 5 bucks each time UPS rings the bell. I forgot to mention that for identically sized packages the fee will vary. Maybe aduanas is pre-voting the Academy. If any of you have experience with international shipping and customs, I'd really appreciate some insight.
