US and European regulations

To ensure the safety of Food Contact Materials (like food and beverage cans), and to facilitate the free movement of goods, EU law provides for binding rules that business operators must comply with.

The EU Rules on food contact materials can be of general scope, i.e. apply to all FCMs or apply to specific materials only. EU law may be complemented with Member States national legislation if specific EU rules do not exist.

In the US the Food and Drug Administration has issued the code of federal regulations (CFR).
