Answer: the tax rate is the same, just look at the number of your delivery goods and declare the value to decide, express customs clearance is the first in the form of KJ3, commonly known as the three free channels, the customs will when sampling to require the recipient to a formal declaration of imports, most people of European and American countries as long as the VAT number, the normal clearance are not the problem identification, direct release samples, formal declaration, direct tax, generally use the post to the hair, very few relevant tax, known as the German will produce, because the post is in private gifts to the customs, are basically go three free channels, inspection rate is relatively low, as far as possible to ensure that the outer packing clean, the rules at the time of shipment, name and description of a complete declaration of value, reasonable, so that better clearance, possibility of small package produce tax is relatively small, the EU countries, generally small package, declared value under 30 euro, produces few duties, but don't confuse in Switzerland, Canada normal 60USD, American 200USD, generally do not produce tariff.
Of course, these are not absolute, only the wise remark of an experienced person, each country to play normal tax case of value-added tax and consumption tax these won't express in different ways and change
In theory, in addition to different forms of transport, the customs fees are the same. Tariff and operating fees are issued by the customs, the same goods, the quantity and the declared value, the customs have no reason for a courier company.
But in the actual operation process, there will be some differences.
Each express company in different countries and regions, the cooperation with government departments tightness, clearance capability and so on have certain difference.
The same product, take the FEDEX to charge tariffs, while DHL and UPS are tax-free. (personal experience, the United States of America)
Turkey the national tariff, go DHL or FEDEX is often several times the value of the TNT, but almost nothing tariff.
Everything is not absolute, in general, Europe and the Middle East to recommend DHL/UPS, ARAMEX/TNT
Thailand India this bird place, with no difference between FEDEX die.
