Abstract Due to vast research programmes of industrial countries during the last two decades, our knowledge about the intrinsic properties of nanomaterials has increased considerably. However, ‘nanoregulation’ lags behind this progress. Key elements of nanoregulation are definition/scope and safety/consumer information. Safety information along the nano life-cycle is vital for the nanoparticle producer down to the industrial downstream user (product producer). However, nanodeclaration (in the sense of a label on the product for consumers) is not yet widely spread, in different geographic regions for different reasons. This is a case study for the EU, Switzerland, Thailand, the USA, and Intergovernmental Organisations. In addition, this study investigates inter- and governmental activities and the relationship between nanodeclaration and WTO rules. Non-compliance with WTO rules is a pretext for not introducing nanodeclaration in products. It is concluded that WTO rules do not exclude nanodeclaration.

欧盟、瑞士、泰国、美国和政府间组织在产品生命周期中的纳米监管及其与 WTO 法律的兼容性

摘要 由于过去二十年工业国家的大量研究计划，我们对纳米材料的内在特性的了解已大大增加。然而，“纳米调节”落后于这一进展。纳米监管的关键要素是定义/范围和安全/消费者信息。纳米生命周期中的安全信息对于纳米颗粒生产商乃至工业下游用户（产品生产商）都至关重要。然而，纳米声明（就消费者产品上的标签而言）尚未广泛传播，由于不同的原因在不同的地理区域。这是欧盟、瑞士、泰国、美国和政府间组织的案例研究。此外，本研究调查了政府间和政府间的活动以及纳米声明与 WTO 规则之间的关系。不遵守 WTO 规则是不在产品中引入纳米声明的借口。结论是 WTO 规则不排除纳米声明。
