I have some close relative who works for BASF and representing in Pakistan. Before Civic X, Atlas used to buy resins for injection molding , some products from BASF and some from another Eureopean brand.
For Civic X they shifted to different products/ raw materials and basically some Chinese brand. Chinese brand does not mean, poor low quality BUT what Atlas selected was like a marginal brand. The same supplier also provide raw to Pak-Suzuki.
The raw material plays very important role in molding plastic parts like door panels, interior plastic trims like shelf behind rear seat, trunk , trims along A , B and C pillars and most importantly the dash boards.
I am sure you guys will agree that quality, fit and finish as well as the texture and feel by touch for platics on 9th generation and even 8th generation was way way better. Even today if you compare used models from previous generations, you guys will see the difference, how well they are crafted and they look completely different even to a layman just by look and touch.
Lastly, Atlas do lot of injection molding work on their own. They created their own companies who supplies them these items.
Again this is the information I have when Civic X was launched in 2016 and we experienced very low quality of plastics. I am not sure what are suppliers today and I dont know if Atlas will switch to better supplier for Civic XI.
