Certifications for cotton drawstring bags from Alibaba: is REACH required?

Hi,

I would like to purchase cotton drawstring bags from Alibaba to be used as packaging for my brand's products.

Initially, I will place a small trial order (300 pieces) to test both the product and the supplier. However, I want to make sure I comply with all applicable regulations from the beginning.

Could you please advise which certifications I should request from the supplier? Is REACH compliance required, or are other certifications sufficient? If so, which ones would you recommend verifying before placing the order?

The cotton bags will have my brand logo printed on them. Do I also need to ensure that the printing ink complies with the relevant regulations (e.g. REACH), or is it sufficient for only the cotton fabric to be compliant?

Thank you in advance for your help.
