I am looking for customs data for importing companies for each country. I found some of them, for instance Canadian Importers Database

But I wonder if any of you know the additional free sources. Especially in case of China or USA.

How to access such data is often described in published papers using data on imports. For the US, see for instance:
Flaaen, Aaron, Ali Hortaçsu, and Felix Tintelnot. 2020. "The Production Relocation and Price Effects of US Trade Policy: The Case of Washing Machines." American Economic Review, 110 (7), 2103-27.
