Because the manuscript has been audited by the external auditor, the external auditor needs fees, and these fees have been paid to the auditing experts, and most of the review fees are relatively cheap, perhaps only a few tens of dollars as a periodical, and the magazine will not directly return them to the author.
For most journals, the review fee will not be refunded after the submission is rejected. The review fee refers to the fee paid to the paper review expert, which will not change because of the review result of your article. Even if your paper is not accepted, your review fee cannot be refunded, so you must consider the possibility of being accepted before submitting it.
The review fee can be regarded as the labor remuneration of external reviewers. As we all know, all formal publications have external reviewers, so it is also common to charge a review fee. Generally, review fees are not very high, and many of them range from 200 yuan to 300 yuan. Only when the author pays the review fee will the article enter the external review link.
It must be clear that paying the review fee does not mean that the article can pass the review smoothly. Moreover, if the article fails to pass the external review and is not published, the review fee cannot be refunded. Even if it fails to pass the external review, the external reviewer has already paid the corresponding labor, so the review fee cannot be refunded.
