"凡购买XX出版社的图书，如有缺页、倒页、脱页者，本社发行部负责调换", does this translation "The house will be liable to replace book(s), should any missing, reversing and loosing pages be found in the books published by XX Publishing House" make any sense to you? Thanks!
It makes sense. The publisher would give you another copy of the book if there is any missing pages(缺页) and upside down pages (倒页). In the sentence, it also mentioned 脱页, which a bit different from 缺页, 脱页 means the page is not "connected" to the book and 缺页 means the page is literally gone, not even in the book.
