The need for trade remedies stems from the challenges of operating globally. Trading internationally carries risks, such as opening the domestic market to the threat of competition. Introducing trade remedies in these scenarios can counterbalance these threats, protecting the UK’s domestic industries.

These duties are additional charges levied on products sold in the UK at prices below their standard value, often due to subsidies or dumping by exporting countries.

Exporters can claim VAT zero rating against official and/or commercial transport evidence of export.
