40GP (40' General Purpose Container)

The 40-foot container (40GP) is a standard container type commonly used in international trade and logistics, referring to a general-purpose container with a length of 40 feet. Its internal dimensions are approximately 12.03 meters long, 2.35 meters wide, and 2.39 meters high, with a volume of about 67.7 cubic meters and a maximum payload of about 26-28 tons (subject to carrier and route restrictions). The 40GP is suitable for transporting general dry cargo, such as clothing, electronic products, machinery parts, etc., and cannot be used for refrigerated or dangerous goods (which require special containers). Compared with the 40HQ (high-cube container), the 40GP is lower in height (2.39 meters vs. 2.69 meters) and has about 9 cubic meters less volume; compared with the 20GP, the 40GP has about twice the volume, but a lower freight rate per unit volume. Use cases include full container load (FCL) ocean shipping, rail transport, and multimodal transport. Precautions: it is necessary to confirm whether the cargo is overweight (to avoid overweight surcharges), whether reinforcement is required (to prevent cargo damage), and whether the destination allows the passage of 40-foot containers (for example, some inland points have length restrictions). In addition, the 40GP is different from the 40NOR (non-operating reefer container), which can replace some general cargo transport but at a higher cost. When quoting in foreign trade, the container type must be clearly specified to avoid confusion with the 40HQ.
