Ecommerce platforms are offering advice to sellers, for example eBay has provided its sellers with a list of providers who offer GPSR compliance services.
However this adds a cost which may be uneconomical to small businesses alongside the added bureaucracy of new labelling requirements.
Emails to customers and social media posts seen by the BBC suggest this is a significant issue for small craft businesses.
For example a stationery and illustration business in Manchester has posted on Instagram: “I’m a tiny one-woman business and don’t have the money, resources or time to implement these new rules.
“So I will no longer be able to sell to the EU and Northern Ireland from 13th December. Brexit really is the gift that keeps giving.”
The rules also impact people selling through platforms like Amazon and eBay.
The EU has been working on the GPSR since 2020 and it was approved by the European Parliament in May last year.
It updates existing rules and its aims include giving better protections for consumers when shopping online and improving product recalls.
