You are absolutely right - it is VERY confusing. In another thread, you stated, "The kit price does not include the tariffs,in that case should be paid by the importer." So who is the importer in this case? If I go to my local department store and buy a Chinese-made item, the department store is the importer and has already paid any tariffs (and passed the cost along to me). If I order from you, aren't you the importer, despite the fact that it is drop-shipped?
Items ordered from overseas are already held up in customs long enough. If customs is going to bill me directly and hold the package until paid, any order like this could take months to receive!
