Use
Some customers may be liable to excise duty at reduced rates or exempt from it altogether (for example, customers abroad). Such businesses must provide you with a copy of their exemption forms in order to claim their exemption.
Activities
If you make a sale to a customer that is in possession of an exemption form, you have to record the form number in the sales order. The system then automatically applies the appropriate rate of excise duty.
When you create the sales order, enter the form, using the customer tax classification fields. Based on the customer tax classification status, you can use different excise rates for a sale transaction.
If the form has not been submitted by the time you create the pro forma excise invoice, the excise value will be recalculated at the normal rate.
