"Do Not Stack" is a common packaging and storage symbol in international logistics and foreign trade transportation, used to indicate that the goods must not be stacked upon or have other goods placed on top of them during warehousing, loading/unloading, and transportation. Its use scenarios mainly include: fragile items, precision instruments, dangerous goods, liquid containers, large machinery, or goods whose packaging strength is insufficient to bear additional weight. Precautions: 1) Standard graphical symbols (such as a wine glass or upward arrow combined with a no-stacking mark) should be used along with text in Chinese and English; 2) It must be clearly marked on at least two adjacent sides of the outer packaging; 3) If the goods can be partially stacked, it should be clearly marked "Stack up to X layers only" or "No stacking." Difference from other terms: "Do Not Stack" emphasizes a complete prohibition of any form of upward stacking; whereas "Stacking Limit" allows a limited number of layers; "This Side Up" only indicates direction and does not exclude the possibility of stacking. Foreign trade practitioners should note that if goods are damaged due to failure to mark correctly, the carrier may be exempt from liability, so it is essential to also note this in the booking and packing list.
📝 Examples
1. Please affix "Do Not Stack" labels on all four sides of the outer packaging of precision instruments and notify the warehouse and shipping company. (Note: When exporting precision instruments, clearly communicate operational requirements to logistics parties to avoid damage caused by stacking.)
2. According to customer requirements, the cartons of this batch of glassware must be printed with "Do Not Stack" and the Chinese characters "请勿堆码"; otherwise, they may be stacked arbitrarily during unloading at the destination port. (Note: Emphasizes the practical impact of marking this term on operations at the destination port to ensure cargo safety.)
