Ar hyn o bryd mae cwynion am arferion masnach annheg neu gynnydd na ragwelwyd o ran mewnforio yn cael eu harchwilio gan y Comisiwn Ewropeaidd (Masnach y Gyfarwyddiaeth Gyffredinol), a chaiff unrhyw fesurau i unioni masnach gael eu defnyddio ar lefel yr UE yn gyfan. Bydd yr Awdurdod Rhwymedïau Masnach mewn ffordd yn cymryd y rôl hon ledled y DU, gan weithredu fel corff cyhoeddus anadrannol, gan archwilio cwynion a gwneud argymhellion ble y bo angen rhagor o weithredu.
Currently, complaints of unfair trade practices or unforeseen surges in imports are investigated by the European Commission (DG Trade), and any trade remedy measures are applied at an EU-wide level. The Trade Remedies Authority will essentially take over this role at a UK-wide level, acting as a new non-departmental public body, investigating complaints and making recommendations where further action is required.
