Harmonized Codes

The Government makes me laugh. Leave it to them to make a 3000+ page document of commodity codes for shipping items internationally. It is near impossible to find anything in there. The parts I am looking for get lost between the numbers for everything from "railway sleepers" to items "prepared for use in making wigs" to "mongolian lamb raw firskins". Wow. How do they expect people to be able to find anything in there???
