If the general price and terms are workable we will then help clients calculate the additional costs to deliver to their location overseas. The freight cost fluctuates widely depending on the number of products shipped and whether we can group many products together and ship on a consolidated basis.
For the USA, we check the import duty with US International Trade Commission for the product codes and their import duty database to see what tax rate to apply. Each country has its own tax rates for imports and it is best to check with us and your local freight forwarders to get accurate and up to date rates.
Apart from calculating freight cost from factory to customer address (depending on the Incoterm we use) another important part of our work is checking the import duties taxes and safety requirements for different markets. ODM use a number of different testing labs for OEM development in China.
