But last Wednesday, the Trump administration said those findings relied on "flawed methodologies and incomplete data".

It criticised what it called the commission's decision to use "information from second-hand single uncorroborated sources", which it said was inconsistent with established UN standards and methodologies.

Researchers said the findings “represent point-in-time results from a small number of product samples” and may not full represent “actual product contents, with testing methodologies varying,” the outlet specified.

Moreover, new complex models need new methodologies that will enable researchers to apply them.

A spokesperson said it was necessary "to dig deeper and understand the context behind the numbers" when comparing regulations in the US and EU, which use different methodologies.
