Rongrik Atoll in the Marshall Islands has limited transport infrastructure. The main delivery method is via sea freight, as there are no major airports in the region. Delivery from abroad can take anywhere from 2 to 4 weeks, depending on the port of departure. Customs procedures tend to be straightforward, but it's advisable to check the required documents in advance. Major courier services may not cover remote atolls, so local delivery solutions might be more efficient.
