This is the reference entry for UN1845.

To verify your actual package — labels, marks, SDS and packaging — scan it with DG Inspector. It reads the real evidence in front of you and shows the reasoning so you can check it.

A reference lookup is a dictionary, not a compliance verdict. It tells you what UN1845 requires; it cannot confirm that your specific shipment meets those requirements.
