Pablo you need a more logical government (so do us Americans). I had a coworker whose wife was from one of the smaller Phillipine islands. She spent $20k to buy appliances in the United States, fly them to Manilla, put them on a boat to the island, drive them to the edge of a mountain, then pack it on a donkey and take it the rest of the way to her mother's place way up in the hills. Refrigerator, microwave oven, washing machine, etc.
All that was cheaper than buying the same product locally and taking it home. The appliances were made in China, taken by ship to California, trucked 3000 miles to Florida, then flown air freight by the pound back to Manilla. All that because so some scumbag in government would get his cut. All this cost Cecillia a year's wages as a nursing assistant.
Lithium batteries are a problem to ship inside the US now. Any loose primary cell lithium cannot legally be shipped by passenger air after Jan 1. The US Post Office uses passenger air to ship mail. Only primary lithium cells installed in a device are exempt from the regulation
