Mail Bag

Mail Bag refers to a specialized bag used in international trade for loading and transporting mail, documents, or small items, typically provided by postal authorities or international express companies. It is mainly suitable for sending commercial documents, samples, small commodities, and other low-value, small-volume goods. Usage scenarios include: sending documents or samples through international postal systems (such as EMS, DHL, etc.); shipping small packages for cross-border e-commerce; diplomatic mail bags for special purposes. Precautions: Mail bag transport usually has weight and size restrictions and must comply with destination country customs regulations; if used for commercial goods, customs declaration and tariff payment may be required; mail bags are generally not suitable for bulk cargo, and their transport timeliness and tracking capabilities are limited. Compared with ordinary sea or air container transport, mail bags are more flexible and lower in cost, but have smaller capacity and relatively lower security. The difference from 'Parcel' is that mail bags usually refer to mail containers transported in bulk within the postal system, while parcels focus more on individual shipments. Foreign trade practitioners should clearly understand the applicable scope of mail bags to avoid customs clearance delays or cargo losses caused by misuse.
