When you ship something from the United States to another country, you must follow both USPS® international shipping regulations and the regulations of the destination country:
If you're shipping within the U.S., see Domestic Shipping Prohibitions & Restrictions.
提醒： You may not ship alcohol-based hand sanitizer or flammable sanitizing wipes overseas.
If you're not allowed to ship an item in the U.S., you're not allowed to ship it to any other country. (And even if it is allowed domestically, it may not be allowed in another country.)
APO/FPO/DPO shipments to foreign countries are treated like domestic mail, but they are still subject to those foreign countries’ laws.
所有 USPS 客户均负责：
- Complying with Postal Service™ regulations and U.S. related laws and regulations.
- Review the USPS Publication 52, Hazardous, Restricted, & Perishable Mail and the International Mail Manual to find out if your item is mailable.
- Review the Individual Country Listings and Requirements by Country & Locality pages to discover if the destination country permits your item.
- Be aware that size and weight standards may differ from USPS standards.
如果您要邮寄包含有害物质 (HAZMAT) 的包裹，您必须将 HAZMAT 包裹与所有其他包裹分开，并将它们放在标有“HAZMAT”的容器中。
Internationally Prohibited Items
These items may not be sent from the United States to any country:
- Hemp-based products (including cannabidiol [CBD])
USPS® 是唯一运送火化遗骸（人类或宠物骨灰）的寄件公司。You may ship cremated remains internationally (if the destination country permits) but must use Priority Mail Express International® and the appropriate customs form. You are required to use a properly sealed funeral urn as the inner primary container. 对于外运送包装，您必须使用我们的两个残骸套件之一，或使用您自己的正确包装的坚固耐用容器，并在包装盒的所有四个侧面，外加顶部和底部贴上“火化残骸”标签 139。在 The Postal Store® 免费订购火化遗骸寄件物资供应。
仅授权制造商和经销商可邮寄或接收枪支。Many countries have distinct domestic laws impacting the shipping and receipt of firearms.
Only lithium cells and batteries that are properly installed in the equipment they are intended to operate may be mailed internationally or to APO/FPO/DPO locations if the destination country and APO/FPO/DPO permit their receipt.
Prohibited Lithium Battery Shipments
- Lithium batteries packed with, but not installed in, equipment
- Lithium batteries sent separately from equipment
- Damaged or recalled batteries
- All pre-owned, damaged, or defective electronic devices containing or packaged with lithium batteries
除了在有限的情况下，不得邮寄宠物和温血动物。活体动物（包括家禽、爬行动物和蜜蜂）的邮寄有非常详细的包装要求。Although you can drop these animals at any Post Office™ location, they are only shipped when the right transportation is available.
