The Edit That Ends the Grandfather
A new product photo on a marketplace listing does something a price cut never will. Uploaded on or after October 13, 2026, it puts that listing under the FCC's ID display rule, which a listing live before that date escapes for as long as nobody touches its content. Where the inventory sits decides the rest, because stock held in the marketplace's warehouse puts the listing under the stricter of two standards, three months sooner.
What takes effect on October 13, 2026
FCC 26-50, the Commission's Third Report and Order, was published at 91 FR 57798 on September 11, 2026 and takes effect October 13, 2026. Under the new § 2.803(a)(1), marketing "includes the listing of regulated equipment on an online marketplace, in combination with any of the following activities: consignment, warehousing, inventory management, order processing, labelling, packaging, billing, or fulfilment services." The rule adds that this holds "even if that equipment is sold or offered for sale by a third-party seller." An online marketplace carries the meaning the INFORM Consumers Act gives it, and a carrier that merely transports devices "without trading in them" stays outside.
The marketplace gets no knowledge defense. "We have considered and decline to adopt proposals to limit marketing liability to those bad actors who willfully or intentionally violate the marketing rules," the Commission wrote, and it turned down the requests for a safe harbor as well.
The display duty in § 2.803(c) is adopted rule text, with compliance dates of March 1, 2027 and June 1, 2027 written into the rule itself. Petitions for reconsideration are due October 13, 2026, and none had been filed in ET Docket No. 21-232 as of October 12, 2026. The tiers and the dates, question by question, are on the logic-bearing components page.
The grandfather has no end date
The display duty does not reach "A listing for a radiofrequency device published before the effective date of this rule, unless and until that listing is amended, updated, or republished on or after the effective date of this rule." The rule then says what counts as an amendment.
- A change to the product description, product images, product specifications or seller information counts.
- A change to search ranking, page layout, translation, pricing or currency display does not.
The order says when the edit takes hold. Any such change "brings that listing within the scope of § 2.803(c) as of the date of the amendment or update." The Commission drew that line deliberately, because making a marketplace retrofit its whole existing catalog "would impose a materially greater, one-time burden untethered from the marketplace's own editorial activity."
A legacy listing that gets a new photo or a corrected spec sheet in November 2026 owes an FCC ID when its compliance date arrives in 2027, while the same listing repriced every week through 2027 stays outside the display duty. An edit made after the compliance date brings the listing in the day it is made.
Where the stock sits sets the date and the standard
Paragraph 74 sorts every listing into one of two tiers, and the test is custody. Listings of the marketplace's own devices, and listings where it "has physical access or takes title to the device (for example, through fulfillment, warehousing, consignment, shipping, or similar arrangements)," fall in the first. Third-party listings where the marketplace never has physical access or title fall in the second.
- Under § 2.803(c)(1), the first tier, the marketplace must show a valid and accurate FCC ID matching the listed product from March 1, 2027.
- Under § 2.803(c)(2), the second tier, it must show a valid FCC ID from June 1, 2027, and it isn't liable for a seller's inaccurate ID if it checked the ID against the Commission's Equipment Authorization System database and required the seller to certify accuracy.
For the second tier the order says the marketplace is "not responsible for ensuring that the FCC ID provided corresponds to the device being offered for sale." The first tier is the reverse.
That puts the choice with the seller, listing by listing. The same model sent into the marketplace's fulfilment program and shipped from the seller's own warehouse sits in both tiers at once, with two dates and two standards. Where the marketplace answers for the ID matching the product, the rule gives it every reason to ask the seller for that ID and check it.
The Commission also said where enforcement under § 2.803(c) will go first, and first-tier listings are on its list.
- Knowing, willful, intentional or negligent noncompliance, including a marketplace that fails to display a required ID "after having been notified of the omission or after a pattern of similar violations."
- Listings in Category (1).
- The marketing of covered communications equipment or otherwise unauthorized equipment.
That statement "does not narrow the scope of § 2.803" and "does not create a safe harbor."
What the display duty leaves out
The display duty does not apply to the following listings.
- A device authorized through the Supplier's Declaration of Conformity. The order says the requirement "applies only to FCC IDs and only to RF devices subject to certification."
- A listing by a third-party seller that is not a high-volume seller. Under the INFORM Consumers Act that means 200 or more discrete sales of new or unused consumer products and $5,000 or more in gross revenue in any continuous 12-month period during the previous 24 months.
- A used device, meaning one previously sold to a retail customer and marketed as used or otherwise not new.
The Supplier's Declaration exclusion lifts the display duty and nothing more. A self-declared device is still regulated equipment under the marketing definition, so a marketplace that lists it with fulfilment when it lacks the authorization it needs is marketing it, with no knowledge element to fall back on. The Commission also declined to require FCC IDs on external packaging "at this time," and kept the record open on that point.
The diligence the Commission described
The Commission said it is unlikely to pursue a marketplace that undertakes reasonable due diligence "even where an isolated or inadvertent listing error occurs," and it named the practices from its Operation Clean Carts initiative it is likely to look to.
- Screening listings for a valid FCC ID or SDoC information.
- "Cross-referencing seller-provided authorization information against the Commission's Equipment Authorization System database."
- "Requiring sellers to certify the accuracy of equipment authorization information as a condition of listing."
- Promptly investigating and removing listings that lack required authorization information.
- "Maintaining records sufficient to demonstrate these efforts upon request."
None of that creates "a safe harbor, presumption of compliance, or defense to liability." According to the order, the National Retail Federation's members "voluntarily verified and removed three million listings in six months."
Where it lands
For a high-volume seller of certified radio devices, two facts decide whether a listing live before October 13, 2026 must carry an FCC ID in 2027 and how strictly that ID is held to the product. One is whether anyone changes the listing's content on or after October 13, 2026. The other is whether the marketplace holds the stock. A listing with both, a refreshed page and inventory in the marketplace's warehouse, must show the FCC ID of the exact model on sale from March 1, 2027. From that date, if a listing of yours can't show one, the marketplace carrying it is out of compliance with § 2.803(c)(1).
