In international trade agreements, restrictions on goods or demands for labelling which differ from country to country can be ‘barriers to trade’, effectively restricting the free movement of goods. Trade organisations which manage such agreements, such as the World Trade Organisation (WTO), have mechanisms in place to ensure that environmental or public health measures are not in fact ‘disguised restrictions on international trade’ which aim to protect national industries. Formal processes exist in the WTO to query public health and environment regulations for their ‘trade restrictiveness’, their necessity and the possibility of using alternatives.
