I recently came across a story about customs enforcement in Singapore that I thought you might find to be of interest.
The case involves a marketing manager in Singapore who was sentenced by a Singapore court to a fine of SGD$92,000 (roughly, $68,000) for counterfeiting U.S.-Singapore Free Trade Agreement Certificates of Origin provided to a U.S. customer, and for making false statements to the Singapore government when applying for the certificates. It appears that the marketing manager was engaged in a scheme to help defraud the U.S. government of antidumping duties (i.e., passing Chinese-origin uncovered innerspring units as being of Singapore origin) and, in the process, making false statements to Singapore Customs. A copy of the Singapore Customs press release is available here.
There are several interesting things about this case. First, the prosecution was based on information supplied to Singapore Customs by U.S. Customs and Border Protection (CBP). It appears that CBP may have uncovered the fraud on the U.S. side and then provided information about the exporter to the Singapore authorities. Second, it appears that CBP may have uncovered the fraud when the U.S. importer/customer underwent a CBP audit. See Headquarters Ruling #h270834 (March 2, 2017).
We hope you find this interesting/helpful. If you have any questions, please let us know.
