On July 20, 2026, the FCC Office of Engineering and Technology (OET) released DA-26-744, instituting ET Docket 26-111 to withdraw the recognition of SGS-CSTC Shenzhen as an FCC-recognized accredited testing laboratory (designation CN1336) under 47 CFR 2.951. The Shenzhen facility is part of the SGS group whose test reports support FCC equipment-authorization filings, and the order follows a notice of intent, DA-26-461, issued May 11, 2026. Recognition has not yet been revoked, but any OEM, importer, or Telecommunication Certification Body (TCB) whose grants rest on CN1336 test data now carries supply-chain risk and should audit active filings immediately.
The move is the latest step in the FCC lab-integrity program tightened by the FCC 25-27 Report and Order, which has already seen recognition challenged or pulled at other China-linked labs, including TTL and CVC. For compliance leads the operational question is not whether the agency posture is shifting, it already has, but whether your FCC ID portfolio depends on a lab the FCC may soon stop accepting.
Which filings are exposed, and what must change?
Any equipment authorized under 47 CFR Part 2 (Certification) or Part 15 that relied on test data from SGS-CSTC Shenzhen (CN1336) is potentially exposed. If OET finalizes the withdrawal, reports from the lab will no longer support new certifications, and existing grants founded on that data could face scrutiny. Affected parties should immediately map their FCC ID portfolio to the testing lab of record, flag every grant that lists CN1336, and identify whether the device can be retested at another FCC-recognized lab before a filing window or shipment deadline closes.
TCBs that routed applications using SGS-CSTC Shenzhen reports should expect to revisit those grants and prepare to re-validate data with an alternate recognized lab. Importers marketing devices under Supplier's Declaration of Conformity are less directly affected, since SDoC for unintentional radiators does not require a recognized lab, but mixed-intent devices certified under Part 15 still fall squarely in scope.
What does DA-26-744 actually do today?
The order institutes a proceeding, it does not yet withdraw recognition. Under 47 CFR 2.951, OET must afford the laboratory notice and an opportunity to respond before recognition is terminated, and ET Docket 26-111 is the docket in which that procedure runs. Parties with an interest in the outcome, particularly applicants and grantees whose filings depend on the lab, can file pleadings in that docket rather than wait for a final order.
Practically, recognition remains technically live as of July 20, 2026, but the prudent compliance posture is to treat CN1336 reports as contingent, not durable. Build the remediation plan now: retesting lead times at alternate recognized labs are the binding constraint, and they lengthen once a withdrawal becomes final and demand surges.
How does this fit the FCC lab-integrity push?
SGS-CSTC Shenzhen is not an isolated target. The FCC 25-27 lab-integrity rules gave OET sharper tools to act against recognized labs with foreign-entity ties or integrity failures, and the agency has used them against TTL, CVC, and now SGS-CSTC Shenzhen in sequence. The pattern signals that any FCC-recognized lab with a China footprint is under heightened review, and that reliance on a single lab for a product family concentrates risk.
| Stage | Instrument | Date | Effect |
|---|---|---|---|
| Notice of intent | DA-26-461 | May 11, 2026 | Signaled OET's intent to withdraw recognition |
| Proceeding instituted | DA-26-744, ET Docket 26-111 | July 20, 2026 | Formal proceeding under 47 CFR 2.951; lab may respond |
| Final order (pending) | To be issued | Not yet set | Would terminate recognition of CN1336 |
Continuous, per-jurisdiction real-time monitoring surfaces this kind of FCC OET order the moment it posts to docs.fcc.gov, so compliance teams can start a lab-mapping exercise the same day rather than weeks after a grant is challenged.

What to do next
First, run an FCC ID portfolio audit against the lab of record and flag every grant resting on SGS-CSTC Shenzhen (CN1336) test data. Second, confirm alternate recognized-lab capacity and book retest slots before a final order converts demand into a queue. Third, file in ET Docket 26-111 if your grants depend on this lab, so your interest is on the record. Fourth, brief product, supply-chain, and customs stakeholders: a shipment held up by an invalid certification costs far more than a retest booked now.
