What is NTB in trade?
A Non-Taroff Barrier (NTB) is a trade restriction–such as a quota, embargo or sanction–that countries use to further their political and economic goals. NTBs may be useful in addressing potential market failures, but they are also prone to capture by protectionist interests. An optimal NTB design requires recognizing that the claimed benefits may come at a significant financial cost and reduced consumer choice.
