I actually contacted their support team about this. According to them, The TID for this cable is 12667. They are licensing it through this other manufacturer but are working through certification with their own USB VID.

Per the USB-C specification table that discusses USB Type-C Standard Cable Assemblies that mentions a "≤ 0.8 m" limit for 40Gbps and 80Gbps cables:
The cable lengths listed in the table are informative and represent the practical lengths based on cable performance requirements.

There have existed 1.2m (4ft) certified 40/80Gbps cables on the market for a couple years now. A few 1.5m (4.9ft) cables have been certified in the last year. This cable is completely legitimate.

This Cable Matters USB C cable stands out as a certified long run for high bandwidth and up to 240W charging, with community confidence that the 4.9 foot length is legitimate for USB4 80Gbps use. The cable is described as well made, reliable, and a good value for a name brand certified option, especially versus cheaper non certified alternatives. It is also framed as suitable for demanding setups like a 4K 160Hz monitor. The main caveat is certification confusion, since the listing shows USB IF verification and Thunderbolt compatible wording rather than a Thunderbolt logo or full Thunderbolt certification.

  • The cable can plausibly support 40Gbps and 80Gbps operation at longer lengths based on USB Type-C standard cable assembly guidance.

  • Cable Matters support provided TID 12667 and explained that licensing and certification involve another manufacturer while certification proceeds under their own USB VID.

    violentleaf

  • The cable can be a practical option for high-refresh 4K monitor setups because returns are easy if it does not work.

    FairScene6701

  • The cable can be a better choice than cheaper non-certified USB4 options when tariffs raise the cost of alternatives.

    az060693

  • The advertised 240W and high-end USB4 performance at 4.9ft can seem infeasible because passive USB4 length limits are often cited around one meter.

    Timless

  • USB-IF certification visibility may be unclear because certification listings were seen for a 3.9ft cable but not for the 4.9ft version.

    mozillaf

  • The listing's "Thunderbolt compatible" wording may not mean full Thunderbolt certification because the cable lacks a Thunderbolt logo and may not pass Thunderbolt's full test set.

    drivel

  • Compatibility expectations between USB-IF verified USB4 and Thunderbolt hardware can be uncertain because USB-IF and Thunderbolt certification processes may differ in specimen selection.

CM makes great products, if for whatever reason you want an official Apple TB4 Pro cable, you can find them for $28 on eBay and $36 on Woot

Is there still a certification process difference between USB-IF and Thunderbolt certified cables? My vague recollection is that USB-IF cables were only certified using specimens sent by the manufacturer, while the Thunderbolt cables were certified by random purchases by Intel on a contiguous basis. The effect being that the best specimens can be sent for USB-IF certification, while the typical specimen may be of lower quality; for Thunderbolt cables, the chances of getting a lower-grade specimen was lower. I had recently gone through six (new, appropriately specced) cables before finding one that worked with a USB-C laptop dock requiring USB 3.2 gen 2; the cable that worked ended up being a Thunderbolt 4 one, backward compatible with USB 3.2 gen 2.

This is the most universal USBC cable option - high transfer, high wattage - and will do anything your usb c port actually supports

Does not have thunderbolt logo on the cable.
Listing does not say it is a thunderbolt cable. It says it is thunderbolt compatible.
This means the cable has never passed the full set of thunderbolt tests.
USB-IF certification is not the same as thunderbolt certification.

Thunderbolt 4 *is* USB4. This cable is verified by a certified third party to meet the signal integrity and other characteristics outlined in the USB specifications, and therefore is functionally equivalent to a certified Thunderbolt cable.

No. Thunderbolt 4 and USB 4 are different standards and have different requirements to obtain certification. They are mostly compatible.

The Thunderbolt 4 physical layer is USB4. In the context of a passive cable, if it has passed 40Gbps or faster certification it is compatible with Thunderbolt hardware. In what ways are they not compatible?
