Reiterating its strict travel ban imposed earlier on seven countries, the Department of Transportation (DoTr) ordered the strict enforcement of testing and quarantine protocols for disembarking seafarers and all inbound international travelers in all ports of the country 'regardless of the specific protocols issued by the local government units (LGUs).'

The DoTr issued a notice on June 19, 2021, apparently to settle once and for all the disagreement over some protocols, specifically the swabbing on the day of arrival of travelers including returning overseas Filipino workers (OFWs) as being practiced in the Cebu province since March 2021.
