I've contacted 2 Chinese companies about buying another Fiber laser. Neither can give me any estimate whatsoever about duties and tariffs, that I need to contact our customs dept, oy...

so I found this online:

it's a screenshot of the harmonized tariff schedule, page 70 of 125, to do with laser engravers...
at the right are columns 'rates of duty', and we have a "1" column of 2 columns, "General" and "Special"...
At the far right is a simple column, "2", with a scary "30%" listed...

what I can't find anywhere is information as to exactly what these percentage numbers actual mean or refer to?

Anybody have a clue?

thanks in advance...
