Sallie James:

[B]ecause implementing the FTAs (which will lower tariff revenue) and paying for the billion-dollar-plus TAA extension “requires” offsets, the draft language specifies in Sec. 601 that revenue should be raised by increasing customs user fees.

Scott Lincicome:

But “customs fees” are simply hidden taxes on import consumers.  A quick review of the US Customs website on “customs users fees” makes this clear.  They’re paid (mainly) by commercial transporters bringing goods (imports) into the United States, thus raising the costs of importation…

[A]ssuming that the agreement would raise US customs users fees (or implement new ones) in order to generate revenue for the federal government, it would probably violate GATT Article VIII, which governs WTO Members’ imposition of “Fees and Formalities connected with Importation and Exportation” (in other words, customs fees).  The key provision of Article VIII reads:

1.(a) All fees and charges of whatever character (other than import and export duties and other than taxes within the purview of Article III) imposed by contracting parties on or in connection with importation or exportation shall be limited in amount to the approximate cost of services rendered and shall not represent an indirect protection to domestic products or a taxation of imports or exports for fiscal purposes.
