Sounds like he mentions one brand , Velospec, that is possibly butted and heat treated in Taiwan.
If a frame is being made in Taiwan, then Reynolds, Columbus, Dedacciai can supply finished tubes to Taiwan.

ORA do have their own proprietry brand, or no name, steel tubes for their own frames.

Reynolds 520 tubes are made in Taiwan.
https://www.reynoldstechnology.biz/materials/steel/steel-520/Reynolds 525, 725, 631, 853 are made in Birmingham, so that they have control over the quality.
For the stainless steels used in frame making, its even more important to control the quality.
Possibly why Reynolds 953 is not available any more.
