When shipments are detained, CBP provides the importer with a list of examples of products from previous reviews and the kind of documentation required to prove they are not made with forced labour, CBP told Reuters. That document, a recent version of which was obtained by Reuters through a public records request, was updated between April and June of this year to include batteries, tyres, aluminium and steel, a CBP spokesperson said. “The timing of these changes does not reflect any specific changes in strategy or operations,” a CBP spokesperson said in a statement, adding that the list of eight product types was “not exhaustive”. The stepped-up focus on automakers follows a study by Sheffield Hallam University in the UK, published in December, that said nearly every major automaker has exposure to products made with forced labour in Xinjiang.
