We run a small ltd company and are selling some small machinery parts to a sister company of BP in Algeria. As far as I am aware we don't charge VAT when we sell them the goods but what about when we buy the goods we are goings sell to them. I.e we will buy the part for £100 + £20 VAT....do we pay the VAT, claim it back, or are we exempt from paying it in the first place as we are buying to export? Any help on this would be great.
