State Sales Tax
You are required to collect state sales tax in most states whenever you sell a physical product to an “end user” in the same state. The “end user” would be the individual by whom it will actually be used as opposed to a distributor or reseller that would actually turn around and sell the item to somone else. Sales tax is only to be collected during the course of the actual consumer sale and is based on the actual cosumer price according to the state and local laws.

You are not required, in most states, to collect sales tax for the performance of a service although many states still require that you register with them anyway. If you provide a service and also sell products then you are required collect sales tax on the sale price of any products that are sold to end users in your state.

If the transactions cross state lines than most states do not require that you charge sales tax on non-residents purchases but the attitude towards this is changing as the Internet continues to evolve and more transactions are conducted via the web.
