How long does USPS First Class International take to ship packages to Singapore?
That's helpful. Is there any way to ensure the package arrives in Singapore faster than 21 business days?
Yes, USPS offers expedited shipping options such as Priority Mail International and Priority Mail Express International which typically arrive in 6-10 business days or 3-5 business days respectively, although they are more expensive than First Class International.
