如何发送包裹：国际

First, check the International Service Disruptions page and make sure USPS is accepting packages going to your destination country.

What Can I Send?

1. See International Shipping Restrictions for general guidance on items you can’t send (prohibited) and items you can send under certain conditions (restricted).
2. Also see additional guidance in USPS Publication 52, Hazardous, Restricted, and Perishable Mail.
3. Lastly, each country has its own rules on what it will and won’t allow: Find your destination country in the Individual Country Listings (which will show you other important information like weight limits and price groups).

How Much Can I Send? (Size & Weight Limits)

Different USPS international package services have different maximum weight limits and then destination countries may have lower limits. There are also limits around the type of things you can send to certain destinations (like just printed material or correspondence) and limits on monetary value (for example, things you send using First-Class Package International Service have a maximum value of $400).

Large envelopes (flats) for First-Class Mail International may not contain goods and must be rectangular, flexible, and uniformly thick, with the following maximum limits: Length 15" x Height 12" x Thickness 3/4", with a max weight of 15.994 oz.

Large envelopes that are bigger than maximum size limits for First-Class Mail International or are rigid or lumpy will be charged the First-Class Package International Service^® (small package) price.

Packages: If you're using your own box, you must stick to the following size limits (note that country limits may be lower):

• First-Class Package International Service: Maximum length is 24”, and combined maximum length + height + thickness is 36"
• For other international packages, length (the longest side of the package) plus total girth (distance around the thickest part) of your package must be under 108". Learn to Measure Package Girth. (Tip: You don't have to measure your package if you use USPS Flat Rate packaging with the matching USPS Flat Rate service.)

See the International Mail & Shipping Services Page for more details about weight and size limits and other restrictions, limitations (including individual country weight and size limits), and available extra features.

Choosing a USPS International Service depends on how much you want to spend, how quickly you want it to arrive, the country that you’re sending to, what you’re sending (and its size, shape, and weight), and if you need tracking or other special features.

For example, one of our most popular services, First-Class Package International Service, can only be used for items weighing less than 4 lbs (64 oz) and worth less than $400.

Or Global Express Guaranteed, which offers expedited, date-certain delivery, serves certain countries and localities.

See more details and features: 比较 USPS 国际寄件服务

说明：If USPS isn't allowed to accept your international package (for example, it's bigger than USPS maximum size limits), you’ll need to choose another carrier.

国际保险与额外服务

You may be able to purchase insurance or other extra services (like Registered Mail^®), though not all features are available for all USPS shipping services and countries. See more information in International Insurance & Extra Services.

• Write down each item (for reference in Step 6 when you complete the customs form), how much it weighs, and how much it's worth—you'll need this information for your customs form (whether you do it at home using our Customs Form Online tool or at the Post Office).
• 用胶带封好包装盒，使它的各个侧面平整闭合，并用 2 英寸宽的包装胶带加固口盖。

If you'll be using Global Express Guaranteed, Priority Mail Express International, or Priority Mail International Flat Rate services, you can get free shipping supplies, delivered to you for free, to use with those services.

Print your return address and the delivery address clearly, on the same side of the box where you’ll be putting your postage, to help ensure your package is delivered on time.

International Address Format Tips

• 以大写字母整洁地打印地址。
• 用钢笔或记号笔书写。
• Don’t use commas or periods.

书写寄件人地址

Write your address in the U.S. (the “return address”) in the top-left corner. 分行书写以下信息：

• 您的全名或公司名称
• 公寓或套房号
• 完整街道地址
• City, State, and ZIP+4 Code^®
• USA

写下投递地址

Generally, you’ll write the delivery address in the center of the label or package (below and to the right of the return address, if possible).

You must write the delivery address in English, though you can include the delivery address in another language (like Russian, Greek, Arabic, Hebrew, Cyrillic, Japanese, or Chinese), if you write the English translation after each line.

Many countries use different address formats (for example, the Postal Code might go before the city). Get specific information about other countries' postal addresses by going to the Universal Postal Union and clicking "Postal Addressing Systems (PAS)."

Generally, include the following on separate lines:

• 收件人全名或公司名称
• 完整街道地址
• City, Subdivision (like province, state, county), and Postal Code
• 国家/地区

See the International Mail Manual for more details on addressing.

注意： If you're sending mail to a U.S. territory, U.S. military base, or U.S. embassy in another country (APO/FPO/DPO mail), see How to Send a Package: 国内。

提示：Also, write the recipient’s full name and address on a piece of paper and put it inside your package.

How to Address International Mail & Packages

A special note on U.S. military bases and embassies in other countries (APO/FPO/DPO Addresses)

APO/FPO/DPO mail going to U.S. military bases and embassies in other countries is special; you pay domestic prices, you use a different address format, and you’ll have to fill out a customs form.

为防止邮件进入外国邮件网络，请在 APO（陆/空军军队邮局）/FPO（舰队邮局）/DPO（外交邮局）地址中不要包含城市或国家名称。Make sure you include the unit and box numbers for APO/FPO/DPO shipping addresses (if assigned).

Make Sure You’re Paying the Correct Postage:

• Make sure the weight is accurate: Use a kitchen scale or postal scale, or have your package weighed at the post office. Include the weight of everything, including packing materials.
• Round up on weights: Some USPS products round up to the ounce, while others round up to the pound. For example, if you’re sending a Priority Mail International package that weighs 5 lbs 2 oz, you would round up to the pound and pay the 6 lb-rate.
• Use the right shipping service: For example, First-Class Package International Service can only be used for packages up to 4 lbs (64 oz) and worth under $400.
• 检查尺寸。If you’re using your own packaging for Global Express Guaranteed, dimensional weight may apply, so always enter your package’s dimensions in the International Postage Price Calculator to ensure you’re paying enough postage.
• Use the correct package label. 请确定您正在使用的标签与包装相匹配。(For example, you can only use Priority Mail labels on Priority Mail International packages.)

附加服务

If you want insurance, proof of delivery, signature services, or other optional services, you’ll have to pay extra.

Our International Insurance & Extra Services page has more details; some of the more common add-on services for international package include:

• Insurance: Global Express Guaranteed, Priority Mail Express International, and Priority Mail International services include some insurance coverage, and you can purchase extra coverage up to certain limits.
• Registered Mail^®：Requires that the recipient sign for the mail to confirm delivery (or attempted delivery).
• 退回收据：You’ll get a printed or emailed delivery record showing the recipient’s signature.
• Certificate of Mailing: Proof that you mailed something from a Post Office.

Find more details on International Insurance & Extra Services.

When you fill out a customs form, you’ll make a list of what you’re sending, including how much each item is worth and its weight. There are also new requirements for providing more-detailed descriptions of contents in packages sent to countries that follow European Union (EU) customs rules. The receiving country may open and inspect your package, so you need to be accurate. You can see more information on our Customs Forms page.

提示：The only time you don’t need a customs form is when you send nonnegotiable documents (like letters or other papers with no cash value) weighing under 15.994 oz using First-Class Mail International^® service.

提醒： When you send packages to U.S. military bases and embassies outside of the United States, even though you’re paying domestic prices, you'll still need to fill out a customs form. 了解军队和外交邮件

When it comes to international packages, what you can put in a blue collection box or Post Office lobby drop is a little more complicated.

You may be able to drop off your international package in a blue box if it meets all the following conditions:

• Your package has a computer-generated customs form
• And you paid for the postage online (like using Click-N-Ship)
• And it weighs less than 10 oz and is less than 1/2" thick

Please see What Can and Cannot be Deposited in a Collection Box^®? as well as specific guidance around dropping off mail that requires a customs form.

Otherwise, you’ll need to give your package to an employee at a Post Office location.
