According to the BOE, California sales tax is charged based on the location where the goods change hands. If you ship them, tax is calculated on your location, not the customer's. Charge the customer location tax only if you make the delivery in person.
If you ship outside of your district, that you are suppose to charge the State wide sales tax rate of 8.25% If I ship in my district (San Diego, then I charge 8.75%.
Straight from the my BOE correspondence....
In summary, based on the above citations and the information provided, if your business is located in San Diego County, you are considered engaged in business in San Diego County. Therefore, when you make a sale to a customer and you ship or deliver the property to the customer anywhere in San Diego County, you are responsible for reporting the 8.75% tax rate. However, if you ship or deliver the property to the customer in another district in which you are not considered engaged in business as defined above, you are required to report the transactions (sales) taxes of 8.25%, but you are not required to report the district use taxes of .50%. As such, it is false to say that if your business is located in San Diego, the 8.75% San Diego tax rate applies to all your sales shipped or delivered throughout California. The tax rate that applies is based on where the product is delivered to the customer.
