USPS (United States Postal Service) offers several international shipping options to China, depending on your needs for speed, cost, and tracking. Here’s an overview of the main USPS international shipping services to China:

1. USPS First-Class Package International Service

• Delivery Time: Typically 7-21 business days (can vary by destination and customs processing).

• Tracking: Provides limited tracking and delivery updates, though tracking might not be available for all regions.
• Weight Limit: Up to 4 lbs (1.8 kg).

This is a good option for light, non-urgent shipments where budget is a key consideration.

2. USPS Priority Mail International

• Weight Limit: Up to 70 lbs (31.75 kg), with larger items requiring specific packaging.

5. USPS Registered Mail International

USPS International Shipping Costs to China (Estimates)

Here’s a quick guide to the approximate costs for sending packages from the US to China using various USPS services, based on the weight of the package:

Customs Considerations

• Customs Declaration: All packages sent to China will need a customs declaration form attached (such as CN22 or CN23) to declare the contents and value of the shipment.
• Customs Duties: Depending on the value and type of goods, customs duties or taxes may apply. The recipient in China may be required to pay these fees upon delivery.
• Restricted/Prohibited Items: Be sure to check the list of restricted or prohibited items for shipping to China, as there are many items (such as electronics, certain chemicals, or agricultural products) that cannot be shipped via USPS to China.

Tips for Shipping to China

• Package Preparation: Use secure packaging, and make sure it is properly labeled with both the sender and recipient’s information, as well as the contents of the shipment.
• Tracking: If possible, opt for a service with full tracking (like Priority Mail or Priority Mail Express), as it will help you monitor the status of your shipment.
• Timing: Keep in mind that shipping to China can take longer than expected due to customs processing. Be sure to check the estimated delivery times based on the USPS service you choose.
