Harmonized Tariff Schedule

To get the "Harmonized tariff number", you'll need to look up the harmonization code associated with whatever product you are selling. You can search for them on http://hts.usitc.gov/. Though some codes may be longer, you only need to pass us the first six digits of the code. Also, remove any “.” in the harmonization code.

Example: the harmonization code for a cotton T-shirt is "6109.10.00", so you'll just pass "610910" as the "Harmonized tariff number".
