The refund system set up to allow companies to recover illegally collected tariffs from the U.S. government went live on Monday as thousands of companies rushed to file claims.'So far, so good' — though the system is a little glitchy, said Jay Foreman, CEO of toymaker Basic Fun, which had a team in its 'war room' at its headquarters in Boca Raton, Florida, ready to start ​filing when the system went live at 8 a.m. U.S. Eastern time.Foreman said the system didn't crash as some had feared it might under ‌the onslaught ‌of attempted submissions — but rather would sometimes not allow an upload and force them to retry. The company has over ​500 files it needs to upload to the system, although the system permits these to be uploaded in batches.
