350.39. The rules set out in the second paragraph apply where(1) at any time section 350.26 ceases to apply to a registrant in respect of a returnable container owned by the registrant at that time or section 350.34 begins to apply to a registrant in respect of a returnable container owned by the registrant at that time; and
(2) in respect of the last acquisition of the container by the registrant, the registrant was not entitled, by reason of section 350.27, to claim an input tax refund or was not entitled to deduct an amount under section 350.35 in determining the net tax of the registrant.
The registrant is deemed(1) to have received at that time a supply of the container; and
(2) to have paid at that time in respect of the supply(a) tax equal to the tax that was payable in respect of the last acquisition of the container by the registrant, or
(b) an amount equal to the amount provided for in section 350.30 that was payable in respect of the last acquisition of the container by the registrant.
