Top Glove, the world’s largest manufacturer of rubber gloves, has been banned from exporting its products from Malaysia to the United States after the US Customs and Border Protection (CBP) made a finding that its products are made using forced and indentured labour.

Rubber medical gloves from a Malaysian manufacturer will be seized if they enter the US due to “conclusive evidence” they are being made by workers under conditions of modern slavery, the CBP said.

Last year the Guardian found that gloves from Top Glove had been supplied to NHS hospitals, although the NHS Supply Chain, an organisation that manages the sourcing, delivery and supply of healthcare products for the NHS, stated that it no longer had a contract with the company.
