Buffer Material

Buffer material in foreign trade refers to auxiliary materials used in packaging and transportation to absorb shock and vibration and protect goods from damage, such as bubble wrap, foam, cardboard, EPE pearl cotton, etc. Its use scenarios include: export cargo packaging, container filling, transportation of precision instruments, etc. Precautions: suitable buffer materials should be selected according to cargo characteristics and mode of transport (sea, air, land), and the destination country's environmental regulations (such as the EU Packaging Waste Directive) should be considered to avoid prohibited materials. At the same time, the cost of buffer materials should be included in packaging costs, and the responsible party should be clearly specified in the contract. Difference from 'Void Fill': buffer materials focus on absorbing impact energy, while void fill focuses on filling gaps to prevent movement; difference from 'Support Material': support material is used to fix shape, while buffer material is used for shock absorption. Foreign trade practitioners need to ensure that buffer materials comply with international transport standards (such as ISTA), and note that they may affect tariff classification (such as being declared together with the goods as packaging).
