Dear Sir,
As a question is from USA, I suppose you are doing e-commerce business from USA using facebook/instagram. You are not supposed to register under GST and pay GST in India. As you said you are paying to your suppliers, I again suppose that you are purchasing the goods from different countries incl. India where GST is applicable. You are engaged in export and domestic sales in USA so person who will import from you in India will be liable to pay taxes depending on the nature of transactions i.e. B2B or B2C. If its is B2B then importer needs to pay GST otherwise not.
Thanks
