CPSC withdrew accreditation from four Chinese labs: check which lab issued your certificate
Facts verified 2026-07-29
The moment a laboratory loses its accreditation, certificates citing it are at risk, regardless of what you paid or whether you knew.
What happened
CPSC announced the withdrawal of accreditation from four consumer-product testing laboratories in China. The published reasons include falsified test reports, concealment of lost accreditation elsewhere, and certifying products that later failed. The named laboratories include Shenzhen GTT Testing Technology Co., Ltd. (CPSC Lab ID 1843).
Actions like this are unlikely to be the last. Enforcement on testing integrity is tightening on both sides of the supply chain.
Why this is not only a fake-certificate problem
A common first reaction: my certificate came from a proper process, so this is not about me. Not necessarily. You may have paid normally, shipped samples, and received a genuine report; if the issuing laboratory later loses acceptance, the foundation of your certificate is in question. A children's product certificate must rest on testing by a CPSC-accepted laboratory. Documents citing a delisted lab face rejection risk in both Amazon reviews and customs entry filings. How existing reports are treated follows CPSC's notices, but waiting for a rejection is the most expensive way to find out.
And if a report arrived suspiciously cheap and fast, with no samples ever shipped, this list is a countdown rather than news. In the eFiling era, the laboratory field travels with every entry and can be checked against the accepted-laboratory list.
The five-minute self-check
Find the issuing laboratory's name and CPSC Lab ID on your test report. Check three things in the CPSC accepted-laboratory database: is it still listed, does its scope cover your product's tests, and is there any withdrawal or limitation on record.
Three results, three actions. Status normal: file a screenshot of the query with the report for the next review. Lab withdrawn or scope mismatch: arrange retesting before the next takedown email arrives. Report of unclear origin: treat it as no report.
