USB-C Cables and E-marker Chip

[maklabouhlel]

I read somewhere that all 240W USB-C to USB-C cables have an e-marker chip and are IF certified. Is this true? I normally buy the 3M Anker ones but there's some 3M ones available by KabelDirekt for less than a fiver which I think is a bargain. The only issue is there's zero mention of it being IF certified but does mention supporting Power Delivery 3.1 with Extended Power Range (EPR) and the integrated chip.
