The US Federal Communications Commission has launched enforcement action against eight companies suspected of helping DJI-linked products continue reaching American consumers under different brand names.

The FCC has proposed fines of US$25,000 (A$36,000) against Cogito Tech, Fixaxo Technology, Lyno Dynamics, Skyhigh Tech, Spatial Hover, SZ Knowact, WaveGo Tech and Xtra Technology after they allegedly failed to respond to official inquiries.

The regulator had asked whether the companies were directly or indirectly marketing radio-frequency equipment linked to manufacturers on its Covered List, which includes foreign drone companies deemed to pose national security risks.

The companies have until July 20 to respond before the FCC considers further action.

Several have previously been linked to products resembling DJI hardware. SZ Knowact and WaveGo Tech have been associated with Skyrover drones, while Xtra Technology sells cameras that appear nearly identical to DJI’s Osmo products.

DJI has not confirmed links to the companies, which publicly operate as independent businesses.

The crackdown could extend well beyond drones. Wireless products require FCC approval before they can be legally imported, marketed or sold in the US, meaning cameras and creator accessories containing DJI-supplied radio components could also face restrictions.

FCC certification documents reportedly linked to DJI’s upcoming Osmo Pocket 4 Pro and Xtra’s similar Muse 2 Pro are no longer appearing in the regulator’s public database, although it remains unclear whether they have been removed permanently.

The FCC is also moving to disqualify Chinese testing laboratory SGS-CTST Standards Technical Services, which reportedly certified several DJI and WaveGo products.

Separately, the regulator has proposed requiring online marketplaces to display FCC certification IDs alongside wireless products, allowing consumers to check whether drones, cameras and connected accessories have been authorised.

The proposed rules would also close a loophole that allows products containing components from Covered List companies to receive approval when sold under another manufacturer’s name.

Existing DJI products will not suddenly stop working, but future drones, cameras and wireless accessories could face a much harder path into the US market.
