tax free clothing

I have a uniform store that I am currently setting up in NYC. They ship to many other tax jurisdictions in NY state requiring that the tax rate of the receiver be charged at time of purchase. To tax the right amount I have them setup for customer taxes. I seem to be running into a problem though, NYS has a tax rate of 4% that is waived for clothing up to $110 and each jurisdiction either taxes up to $110 or not. Here is my problem, there are some items that are taxable at full rates as they are not clothing. So if their system is configured for customer taxes how do I have the item tax out at the correct tax rate? If it is clothing the item either is taxed at no tax rate or half the full tax rate. If it is non clothing it is taxed full amount. Did I miss something here?
