The scope here is Department-wide. DD Form 2521 — DD Form 25 21, Hazardous Chemical Warning Label (8 x 11), October 2000 — exists to Hazardous Chemical Warning Label (8-1/2 X 11), and it applies across the services rather than inside one. That is what the DD prefix encodes: joint issue, single edition, every branch and defense agency working from identical paper.
not stated is the prescribing publication and not stated the office responsible for the document. Deadlines belong to local implementing guidance, not to either of those, so a submission date is a question for the receiving office.
Current edition is not stated, carried as not stated. Check that against any copy you already hold before doing anything else — Department-level revisions land everywhere simultaneously, so a stale file is stale across the whole Department.
The set is PDF. Size: 1 pages, about 19 fields. Everything below refines that choice.
Default to fillable pdf, print only when you must. The fillable file stores what you type; the printable file is a blank picture. A Department form often travels further than a service form — scanned, emailed, forwarded to an agency that never saw the original — and typed text is what survives that.
All formats are free. One operational note: save the file locally and open it in a desktop reader. Browser-embedded viewers drop field properties and lose typed data without warning.

Start by matching the printed date to not stated. Old blanks accumulate in shared folders for years. Because the Department reissues to all services in one action, nobody is still accepting the previous layout by local custom.
For anything ambiguous in a specific field, the form's own instructions come first and not stated controls where the two differ.
Send it as not stated or local guidance specifies. Save a copy. Cross-service and cross-agency routing is normal for Department forms, and a lost original outside your own organization is harder to chase down.
A number is a complete address in the DD series. Because the sequence is Department-level and not duplicated per service, there is nothing further to specify.
Do not read across from a service number. DA numbering is Army-specific under an Army proponent; DD numbering is Department-wide under not stated or an equivalent Department office. The sequences are unrelated, so identical digits in each identify two different documents. Read the prefix, not the digits.
Three drivers of revision: directive reissue, altered collection requirements, updated statutory notice text. No notification accompanies any of them, so download fresh and confirm not stated rather than reusing an archived file.
Limits of this page: it distributes a published Department of Defense document and describes it. No legal advice, no procedural ruling, no statement about whether any submission will be accepted. Applicability, eligibility and procedure belong to not stated, to a servicing personnel office, or to the office named in not stated.
