I've seen this on multiple Facebook sites. It's not reflected on the EHAS page yet.
"COVID-19 Insurance for St. Maarten price decrease
The cost for COVID-19 insurance to visit St. Maarten for non-residents has decreased from US $30 to US $15.
The decreased cost is reflected in the St. Maarten EHAS form and is applicable as of August 1, 2021.
The decreased price for the risk management insurance comes as tourist arrivals to the country increase.
