📦 Service Details and Alternatives
Service Overview: The China Post International Large Package service is designed for items over 2kg, with a weight limit that can be 20kg, 30kg, or 40kg depending on the destination. It is a more economical but slower option compared to express carriers.

Alternative Shipping Options: For faster delivery, you could also consider international express carriers like FedEx, DHL, or UPS. While generally more expensive, these services offer quicker transit times and more detailed tracking.

Required Documentation: When shipping internationally, you will need to complete a customs declaration form describing the contents and value of your shipment.

💡 Suggestions for Your Shipment
Confirm at the Post Office: Visit a local China Post office in Shanghai to get the most accurate and up-to-date pricing for Panama, confirm the availability of Surface mail, and complete the mailing process.

Consider Express for Urgency: If your delivery timeline is tight, comparing quotes from express carriers like DHL or FedEx might be worthwhile for their speed and comprehensive tracking.
