A labour rights organisation claims it has found evidence of worker exploitation in a Chinese factory that makes the viral Labubu dolls.
China Labor Watch (CLW), a US-based non-governmental organisation, alleges that its investigation found that one of Pop Mart's suppliers made employees work excessive overtime shifts, sign blank or incomplete contracts and did not give them paid leave.
The furry Labubu dolls have surged in popularity around the world in recent years and are best known for selling toys in blind boxes, which hide its content from buyers until it is opened.
Pop Mart told the BBC that it is investigating the claims.
The Beijing-based toy retailer said it appreciated the details from the review and that it will firmly require companies making its toys to correct their practices if the allegations are found to be true.
Pop Mart added that it conducts regular audits of its suppliers, including yearly independent third-party reviews carried out by internationally recognised inspectors.
CLW published its report detailing an in-depth probe into Labubu-maker, Shunjia Toys Co Ltd, in the southern Chinese province Guangdong.
The BBC has been unable to contact Shunjia Toys Co Ltd for comment.
CLW indicated that its researchers conducted 51 in-person interviews with the factory's employees regarding recruitment, contracts, and working conditions.
The factory is a core manufacturing facility of Pop Mart toys and employed more than 4,500 workers, according to CLW.
The organisation flagged labour issues at Shunjia Toys Co Ltd's factory in Xinfeng County, including illegal overtime hours, unclear contract practices, and a lack of safety training and protections.
No child labour was identified at the factory, but it had employed 16-year-old workers who were subject to the same working conditions as adults, without special care that is required under Chinese law, said CLW.
It urged Pop Mart to take immediate action to address the issues in its supply chain. The non-profit asserted that the firm should compensate affected workers and ensure compliance with Chinese labour laws and internationally recognised labour standards.
Such facilities, called original equipment manufacturers (OEM), make products according to client-set pricing and production schedules. The CLW stated that this greatly shapes labour conditions.
Labubus - the fictional elf-like creatures with jagged teeth - have gained massive popularity, leading to long queues in shops worldwide.
Celebrity endorsements from figures like Kim Kardashian and Lisa from K-pop group Blackpink have propelled Pop Mart as a major toy retailer.
