If a registrant has received a supply of property (other than a supply that is included in any provision of Schedule VI other than section 1.1 of Part V of that Schedule) from a supplier to whom the registrant has provided an export certificate (within the meaning of section 221.1) for the purpose of that supply and an authorization of the registrant to use the certificate was not in effect at the time the supply was made or the registrant does not export the property in the circumstances described in paragraphs 1(b) to (d) of that Part, the registrant shall, in determining the net tax for the reporting period of the registrant that includes the earliest day on which tax in respect of the supply became payable or would have become payable if the supply were not a zero-rated supply, add an amount equal to interest at the prescribed rate on the total amount of tax in respect of the supply that was payable or would have been payable if the supply were not a zero-rated supply, computed for the period beginning on that earliest day and ending on the day on or before which the return under section 238 for that reporting period is required to be filed.
