Q: Is VAT included in your zipper quotations?
Tax treatment should be stated explicitly, because a quotation can be read either way. Ask for the price basis: ex-works, FOB or delivered, and whether the figure includes value-added tax or export tax treatment. For export orders, a supplier may quote without domestic VAT and handle the export declaration separately; for domestic sales, the rate and the tax base should appear on the invoice. The practical rule is to request two figures, net and gross, or a single figure with a clear note. Confirm the currency and the exchange rate reference if the quote is not in your settlement currency. Also confirm what the invoice will show, since the customs value and the payment record must agree. A quote that hides tax in the unit price makes comparison impossible and can create a surprise at payment. Put the tax clause in the purchase order, not only in the email thread, and check that the proforma invoice repeats it.
