For example, freezers that require CFC’s can be freely exported from, say, Sweden, where they can no longer legally be refilled when required, to Egypt, where refilling is allowed. The rapid increase of foam plastic production in export processing zones is thought to be based on their purchase of CFC-dependent production units from OECD countries.
另外一个问题是，没有任何措施对销售那些只能靠被禁物质运行的旧设备进行限制。比如，需要充入CFC’s的冷冻器能自由地从，比如瑞典，出口到埃及，在瑞典，这些冷冻器再也不能合法充入化学剂，而在埃及，这却是可以的。出口加工区内快速增长的泡沫塑料生产被认为是建立在他们对来自OECD国家依靠CFC的生产单位的购买基础之上。
