Multiple tax values for products

Hi

In Portugal we have several tax values for example 5%,12%, 21% .
In the store i'm assemblying some products will have 5% others will have 12%.
How can i map different tax values for each product?

Thank you very much.

Hello.

Go to configuration->tax->tax classes. Were create 4 classes. (isenta, reduzida, intermedia, normal for ex.)
Then go to configuration->tax->tax providers and edit the provider. In the configuration tab add 4 providers and configure the provider. (Country portugal, tax class normal, Percentage 21 for ex.)

Thank you very much for your reply it works !

Just another thing, this is about shipping, i want to do the following for postal codes between 9000 and 9900 the shipping value is 0, how can i do that?

Thanks in advance for your precious help.
