Zhejiang Entry-Exit Inspection and Quarantine Bureau checked the quality of 20 samples from imported toys sold on cross-border e-commence channels last year and 16 failed the test, said the Weekly Quality Report, a China Central Television (CCTV) program committed to exposing quality issues.

It means that 80 percent of the toys sold on cross-border e-commence do not even meet basic domestic standards.

There are lots of problems in imported toys and the biggest threat comes from children's scooters, the report said.

In the lab, inspection personnel conducted crash tests. The tests found that one of the two batches of products examined was broken. In other words, it could harm children when scooters bump into steps or other objects.

"Consumers usually think imported toys are safer, but the tests showed that there might be some distance from consumers' expectation," said Shen Yuxiang, director of the Inspection and supervision department under Zhejiang Entry-Exit Inspection and Quarantine Bureau. "Not all imported products are qualified".

The General Administration of Quality Supervision, Inspection and Quarantine said it will strengthen the inspection and supervision of imported children's products.
