US Gov implications for fraud on foreign country's customs?

What obligations, liabilities, or penalties under US government contracting law might there be for a US contractor whose overseas personnel may have committed fraud (but not bribery) on a foreign government's customs?

Company A is a US company that makes and sells supplies (clothing) to both commercial buyers and governments. Company A sells to the USG both directly and via a reseller with a GSA schedule. Company A also sells in overseas markets.

Company A has just begun an internal investigation whether one of its lower managers has instructed his people to do a "bait and switch" to minimize a foreign country's import customs duties. Basically, the suspicion is that the manager told his people to submit one set of goods to the foreign customs, as a sample of the goods being imported, to get a lower customs duty, with the plan of importing similar but different, higher-vlaue goods. Apparently, this is common in the foreign country but not consistent with Company A's way of doing business. Company A's foreign lawyers are confident that the matter is not very serious and will not result in any foreign penalties. Company A just wants to make sure that it doesn't have any problems with its USG contracts or subcontracts from this foreign problem.
