One can find all of the tariffs online:

If you are really concerned, find the correct tariffs and have that put on the customs declaration when it is mailed. For assistance, once can also call the customs office and speak to an officer. I have found them quite helpful.
By doing the above I avoided all duty on importing my housing and strobe into the USA from Germany.
Great info ... thanks for the tip! I tried to call Customs, finally found a general info number, called and listened to the 137-item menu, then was told I was the 19th call in line. I hung up. If, by chance, you have a more direct phone numbr, I'd love that! Otherwise, I'll simply refer to:
Harmonized Tariff Schedule of the United States (2011) Annotated for Statistical Reporting Purposes
Chapter XVIII, 90-4, Heading 9002, Sub-Heading9002.19.00, Stat. Suffix 00
2.3%
Now isn't that easy??? Not ...
