It also doesn't have expedited brokerage, which means packages can "sit in customs" for up to 4-6 weeks. Packages are sometimes not delivered at all (1% of cases), so this method is to be used at your own risk!
Due to transportation changes currently underway, the Postal Service advises that customers may experience longer than usual delivery times for mail service to Cuba.
The Postal Service is working to resolve these transportation issues as quickly as possible to restore normal service expectations for mail and packages to Cuba.
For any returned item bearing a customs form, as well as any item shipped with Priority Mail Express International service, the Postal Service will, upon request, refund postage and fees on mail returned due to the suspension of service.
For all other returned items not bearing a customs declarations form, the Postal Service will, upon request, refund postage and fees on mail returned due to the suspension of service, or the sender may remail them with the existing postage once service to Guatemala has been restored.
