Reciprocal Tariffs being collected yet?

Has anyone been able to confirm if shipments that were already in transit before April 9th are exempt from the reciprocal tariff rate? I know the initial round of 20% on China is being collected, but I read on the White House website that there was an exemption on the reciprocal tariffs for freight en route. Anyone had any shipments come in yesterday/today that can confirm that?

Thanks!
