Is puerto rico domestic or international mail

Puerto Rico is a U.S. territory, which means that mail sent to and from Puerto Rico is considered domestic mail within the United States. Here's why:

1. Puerto Rico is a U.S. territory: Puerto Rico is a self-governing territory of the United States, with its own government and constitution. As a U.S. territory, it is subject to the jurisdiction of the United States and is not an independent country.
2. Domestic mail rates apply: The United States Postal Service (USPS) treats mail sent to and from Puerto Rico as domestic mail, which means that you pay domestic mail rates, not international rates.
3. No customs forms required: Since Puerto Rico is a U.S. territory, there are no customs forms required for mail sent to and from Puerto Rico. This is different from international mail, which often requires customs forms and may be subject to duties and taxes.
4. Same delivery standards: Mail sent to and from Puerto Rico is subject to the same delivery standards as domestic mail in the United States, including delivery times and tracking options.

However, it's worth noting that some services, such as Priority Mail Express International and First-Class Package International Service, may have specific requirements or restrictions for mail sent to and from Puerto Rico. Additionally, some items, such as certain types of merchandise or packages containing hazardous materials, may require special handling or permits.

In summary, mail sent to and from Puerto Rico is considered domestic mail within the United States, and you pay domestic mail rates, without the need for customs forms or international rates.
