The Dutch Government will be requiring all arrivals, over the age of 13, to have taken a COVID test (with a negative result) within 72 hours of arrival at the airport. The test must be a “molecular PCR-test for Sars-Cov-2/COVID-19”. Rapid tests will not be accepted.
The Schipol web site states that passengers “are required to show your airline a declaration that you tested negative for COVID-19. The declaration must be brought with you throughout your entire journey. This can also be done digitally. Your negative test declaration may be checked when you arrive at Schiphol. This obligation applies to all passengers flying to Schiphol, transfers included.”
