# Plastic Shopping Bags: Trade Body Accreditation Guide

In the UK, plastic shopping bags are primarily regulated under the Carrier Bags Charge Regulations 2015, which requires retailers to charge for single-use carrier bags and donate proceeds to environmental causes.

Legitimate accredited suppliers will have no hesitation providing proof of their certifications, including valid certificates with expiry dates and scope details.
