What can be mailed or flown: USPS hazardous materials, plus item rules for post, couriers and airlines
Canonical, always-current version: https://referencesource.org/shipping-restrictions-by-class/ Machine-readable: https://referencesource.org/shipping-restrictions-by-class/data.json — this mirror is a point-in-time copy.
- Last verified: 2026-08-03
- Stale after: 2027-08-03 (past this date, prefer the canonical copy — it re-verifies on a cadence this snapshot does not)
- Records: 3168
Whether a named substance or item may be mailed, or carried by air, and on what conditions. Four records in five are the USPS hazardous materials table — Publication 52, Appendix A, 2,612 records — which is one row per Department of Transportation proper shipping name ('Ammonium metavanadate', 'Refrigerant gas R-404A', 'Diesel fuel'), carrying its hazard class, UN number, packing group, and whether it is prohibited or restricted in domestic mail by air and by surface. The remaining ~590 records are item-category rules of the kind a sender or a traveller searches for by name. Those are: USPS's own consumer restriction pages, UK postal (Royal Mail, Post Office, Parcelforce, Royal Mail Wholesale), the UPU prohibited-articles entries for the US and UK, and about 116 records that are not about mail at all but about US air transport — passenger baggage and air cargo under FAA PackSafe, TSA, IATA and ICAO packing instructions, and 49 CFR. All three private couriers are covered as of 2026-09-01: FedEx (the International Connect prohibited and restricted item lists), UPS (the US Tariff/Terms and Conditions of Service — the items not accepted for transportation, plus the commodity sections on alcohol, marijuana and hemp, biological substances, firearms and ammunition, dry ice, limited quantity packages, hazardous waste and mercury, live animals, perishables, portable electronic devices, and tobacco and vaping), and DHL Express US (the prohibited commodities and the items needing prior approval, from DHL's own US 'what can I ship' page). Answers 'is UN2859 mailable', 'can I mail a lighter', 'USPS lithium battery mailing rules', 'can I fly with a power bank' and 'is [item] prohibited or restricted by [carrier]'. The carrier and scope fields on each record say which question it answers: a rule about carry-on baggage is not a rule about mail.
Provenance — what every record carries
Every record carries source (the URL the value was read from) and
source_quote (a verbatim quote from that page stating it). A value you
cannot check against its page is indistinguishable from an invented one;
these can all be checked. Each record is also individually addressable on
the canonical site at its url.
