How can I include Excise Tax for each product in my online store?

[Shahzaib_Saleem]

Hello, I am creating a Shopify store for a Vape Brand in Canada. Shopify store allows me to add GST/HST/PST according to different provinces in Canada. However, there is an additional Excise Tax of CAD 6 (this tax is fixed and not a percentage) on each POD that I am selling. How can I show excise tax for each POD and show it to customer in the tax breakdown.
