Yes, after the TEMU sample has been sent, the seller can still modify the product information, including the product title, description, picture, price, etc. However, modifying the product information may cause the sample to not meet the requirements, thus affecting the review results. Therefore, sellers should be cautious when modifying product information to ensure that the modified product information still meets TEMU's requirements. If the seller finds that the sample does not meet the requirements after modifying the product information, they can try to resubmit the sample.
