International Shipping Restrictions, Prohibitions, & HAZMAT

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:

  • 有些物品是禁止的(完全禁止)。
  • 有些是受限的(在某些条件下允许)。
  • Hazardous materials (HAZMAT), also known as Dangerous Goods (DG), may be prohibited or restricted.

If you're shipping within the U.S., see Domestic Shipping Prohibitions & Restrictions.

提醒: Mercury (a silver metal that's liquid at room temperature) is prohibited and can't be mailed internationally, whether by itself; in devices like antique thermometers, barometers, and switches; or as mercury vapor contained in devices like compact fluorescent lamps. 了解更多信息


  • If you're not allowed to ship an item in the U.S., you're not allowed to ship it to any other country.
  • Other items are specifically prohibited from being mailed to any other country.
  • Finally, each country has its own rules on what it will and won't allow: Find your destination country in the Individual Country Listings.

Shipments to U.S. military bases and embassies (APO/FPO/DPO) in foreign countries are treated like domestic mail, but they are still subject to those countries' laws.

所有 USPS 客户均负责:

  1. Complying with Postal Service regulations and U.S. related laws and regulations.
  2. Complying with the laws of your destination country.
    • Review the Individual Country Listings to discover if the destination country permits your item.
    • Know that a country’s size and weight standards may differ from USPS standards.
  3. 安全包装您的包裹,并根据要求对其进行标记。您可以将您的包裹带到 Post Office 邮局地点,以确保其贴有正确标签。
  4. Accurately filling out customs forms (including more-detailed package descriptions required by countries that follow European Union (EU) customs rules).

Shipping Hazardous Materials (HAZMAT) & Dangerous Goods (DG) Internationally

Hazardous materials (also known as dangerous goods) are substances that could injure people or cause damage if not handled properly, like chemicals or flammable items.

HAZMAT 还包括锂电池(如手机和电子产品中的电池);它们含有大量能量,可能具有火灾风险。

  • Some HAZMAT is prohibited—you can't send it through USPS and must use another carrier.
  • 其他 HAZMAT 受到限制,如果您遵守所有规则,您可以邮寄它。
  • Some HAZMAT can only be sent in ground transportation—it can't go on airplanes.
  • 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。

如果您故意邮寄对生命、健康或财产有危险或伤害的材料,则每次违规将面临至少 250 美元(但不超过 100,000 美元)的民事处罚、任何清理费用和损害赔偿。您也可能面临刑事处罚。
