6- How much import duty will I need to pay for my goods?

There is no single answer to this question but a few rules apply. For customers in USA, TDB Prototypes to be used exclusively for development, testing, product evaluation, or quality control purposes, allow for a MFN Duty Rate of duty-free import into USA(US HTS Number: 9817.85.01.). Import duties vary widely between countries, and are dependent on the type of good being imported. Most countries in the world conform to the international Harmonized System (HS) codes that categorize virtually all commercial trade goods.
