On April 15, the Chinese Embassy in the United States announced on its official website that starting April 22, a series of adjustments will be made to the pre-boarding COVID-19 testing requirements for passengers traveling from the U.S. to China.
The “dual nucleic acid test” or “dual nucleic acid and antibody test” is adjusted from 48 hours to 24 hours before boarding. An antigen test must be done within 12 hours before boarding.
“Dual nucleic acid test” applies to those who have completed the vaccination scheme. Meanwhile, the “dual nucleic acid and antibody test” includes a nucleic acid test and serum-specific IgM antibody test, which applies to those who have not completed vaccination.
The health code introduces the “blue code” concept. For passengers traveling from the U.S. to China, except for the antigen test within 12 hours before boarding, other test results and documents will be submitted to the embassies and consulates in the U.S. for review and approval. After passing the test, they will receive a “blue code” and board the plane with the “blue code and antigen test report within 12 hours”.
In addition, the embassy and consulate no longer issue a “green code” in normal circumstances. If a “green code” is obtained under special circumstances, the “green code” can be used to continue boarding.
