Ludwig's WRAP-UP
According to Ludwig AI, the phrase "is supplied when requested" is a grammatically correct and highly efficient way to describe conditional availability in professional writing. While exact matches are less common than variations like "<a href="/s/is+provided+on+request" target="_blank" rel="alternative">is provided on request", its usage is deeply rooted in the Scientific and Formal & Business domains. It effectively utilizes the passive voice to maintain a neutral tone, making it ideal for academic methodology sections, legal terms, and technical manuals. Writers should feel confident using it to clarify that a resource is available but requires a proactive request from the recipient.
