It shouldn't count. The goods you purchase are reprocessed, and the finished products use their own trademarks, which means that your company buys semi-finished products, and then further processes them to meet your requirements and become your products. Has nothing to do with trademark infringement.

"Changing its registered trademark without the consent of the trademark registrant and putting the goods with the changed trademark on the market again." There is a saying that "change its registered trademark and put the goods with changed trademarks on the market again", which is different from your current situation. But in order to have problems in the future, your company must be prepared to provide evidence, that is, evidence that you have processed the goods after receiving them (samples can be compared).
