Thank you for the question.
The practice is to conduct periodic verifications of importers, and in doing so, to investigate the documents with respect to their importations. I'm talking generally across the board. We will assure ourselves that in fact the imported product was properly classified at the time of importation. If it's not properly classified, we can ask them to reassess their importation. If that results in a change in the rate of duty that's applicable to the import product, they would be required to pay that amount to the government.
