I received one sample under TNT no. 385991718 of not more than 20gm of glass wool insulation from China with inv value of US$ 1.00. Kuwait TNT charged KD 2.800 as costoms and other charges. TNT Kuwait paid total custom KD 12.500 for eight packages of 50kg to Kuwait customs (custom declaration no. 93338). How they charged this much custom where the custom duty is 5%. I would like to know this. Thanks, Hamza Vohra
