Classify 550 Items for Harmonized Tariff Schedule HTS

Hi Have imports coming over and need all of the items (roughly 550, at least a quarter of these are simply different year, model and color of the exact same thing) classified for duty/HTS purposes. MUCH prefer someone that has done this sort of classification work before. These are all auto parts. Items are listed line by line in a spreadsheet with small descriptions of what the item is. Also, the full range of HST designations have been given to me by the manufacturer (total of only around 26 different ones). A sample is: 70091000.00, 87082990.00. All listings have part numbers and a catalog with pictures corresponding to those part #'s. So I'll need you to fill in the spreadsheet with the appropriate tariff/rate/HST # based on the small description and then calculate total duties paid. I would prefer someone that is more aggressive in classifying. Thanks! -Ron
