Whenever the law or any order, rule, or regulation of any other state of the United States or of any foreign sovereignty having the force of law operates as to expose beverages manufactured in this state to liability to any tax, assessment, impost, or other charge which is intended to give or has in practice the effect of giving any beverage manufactured in the state or sovereignty in question a market advantage over beverages manufactured in this state and transported to and intended to be sold in that state or sovereignty, then the service charge authorized by § 3-10-16, imposed or to be imposed upon beverages manufactured or exported from that state or sovereignty into this state shall be in an amount at least equal to the tax, assessment, impost, or other charge imposed by that state or sovereignty upon the like beverages manufactured in this state and shipped into that state or sovereignty. In case, in the judgment of the department of business regulation, a service charge equal to that tax, assessment, impost, or other charge is not sufficient to bring about the removal of the discrimination against beverages manufactured in this state in favor of beverages manufactured in that state or sovereignty, then the department shall impose any additional service charge or charges as in its judgment will be adequate to that end.
