I have a hard-copy or scan of an SDS file

Upload it the same way as any other file — SDS Manager only needs a slightly different path once it's in, since a scan usually has no selectable text underneath it:

1. Upload your scanned or photographed SDS like any other PDF
2. If SDS Manager reports that no text was found, that's expected for a scan — it just means it can't read the page as plain text yet
3. Click "Retry import using OCR on file" so SDS Manager reads the image itself and extracts the data. This works best on a clear, well-lit, high-resolution scan
4. If OCR still can't get a clean read, get a better copy from your supplier, or fall back to entering the product information manually from the import status page's edit icon

This is the same OCR/manual-entry fallback covered in more depth under troubleshooting PDF import failures — worth reading if OCR doesn't work on the first try.
