Reference data transcribed from the published Dangerous Goods List. It is not legal advice and may not capture entry-specific exceptions, special provisions or packing-group ranges. Always verify against the current regulation edition for a specific shipment.

This is the reference entry for UN3529.

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 UN3529 requires; it cannot confirm that your specific shipment meets those requirements.
