A search, an entry and a pair

Placardex on iPhone: the search 1993 lists six entries, among them NA1993 Diesel fuel and UN1993 Flammable liquids, n.o.s., each with its class, packing groups and label, with filter chips for class 3, combustible liquid and packing group, and the edition line at the foot.
Search by UN number or shipping name
The entry for UN1017 Chlorine: Division 2.3, labels 2.3, 5.1 and 8, inhalation hazard Zone B, no packing group; reportable quantity 10 lb (4.54 kg), listed in Appendix B, forbidden on passenger aircraft or rail car and on cargo aircraft only, vessel stowage D.
Every column, with RQ and Appendix B
The pair Gasoline with Chlorine: letter O, section 177.848(e)(3), with the regulation's words for O, and the table cell, row Poisonous gas Zone B 2.3 by column 3.

What it does

  • One search. “1203”, “UN1203”, “NA1993” or part of a proper shipping name, with results as you type. Narrow them by class or division, by packing group, or to a listing in Appendix A (RQ) or Appendix B (MP).
  • Every column. Symbols, proper shipping name, hazard class or division, identification number, packing group, label codes, special provision codes, packaging, quantity limits and vessel stowage. An entry with several packing groups shows each value for every one until you choose the one on your papers.
  • Load check. Add materials by number, name or class, and every pair is checked at once against the §177.848(d) segregation table, often called the hazmat compatibility chart, worst first: the letter X, O or a blank, its row and column, and the regulation’s words. On Search, tap a class to see its row of the table.
  • Built for today’s phones. Liquid Glass on iOS 26 and later; Material 3 Expressive on Android. Dark mode, large text, VoiceOver and TalkBack. Two panes on iPad, tablets and unfolded foldables.
  • From the system. Find a material in Spotlight, or look up a UN number with Siri and Shortcuts. On Android, long-press the icon for Search and Load check.

Reference only

Reference only — verify against the official 49 CFR text and your company’s own HazMat training/certification before shipping.

Placardex shows the regulation’s text. It does not classify a shipment or approve it, and it does not give emergency response guidance.
