Are dry ice packs UK legal to ship in 2025?
Short answer: yes—if you use a DG‑capable carrier and follow UN1845 rules. Postal networks in the UK (Royal Mail/Parcelforce) do not accept dry ice. Private express carriers (DHL, Fedex, UPS) do accept it when prepared under IATA (udara) and ADR (road) provisions. For GB road legs, UN1845 is not subject to ADR except 5.5.3 when used as a coolant, so you manage ventilation and marking instead of full DG papers.
In practice for you: choose DHL/FedEx/UPS for dry‑ice lanes; never post dry ice at retail counters. For air exports, follow IATA PI 954 and complete the air waybill line for UN1845.
What must be on the box and the waybill?
Put this on every package and you’ll cruise through acceptance.
| Checklist | On the package | On the air waybill | Why it matters to you |
|---|---|---|---|
| Identity & UN no. | “Dry Ice” or “Carbon Dioxide, solid”; Dan1845 | “UN 1845, Es kering, [TIDAK. of pkgs] × [net kg per pkg]” | Clear, scannable compliance; avoids handbacks. |
| Hazard class | Kelas 9 label (100×100 mm) | - - | Required label drives automated DG checks. |
| Quantity | Net dry‑ice weight in kg | Net kg totals | Staff plan stowage/ventilation; avoids relabeling. |
| Parties | Shipper and consignee names/addresses | Shipper/consignee fields | Traceability; stops counter holds. |
| Packaging | Vented rigid insulated outer (no airtight seal) | - - | Prevents pressure build‑up; protects handlers. |
Copy‑paste label text:
UN 1845 – Dry Ice (Karbon dioksida, padat) – Net dry ice: [X] kg.
How much dry ice do dry ice packs UK shipments need?
Rule you can trust: plan 2.3–4.5 kg per 24 h of transit, then add a full extra day as buffer. Heavier insulation needs less; hot depots and vans need more. This keeps frozen products solid without overspending on CO₂.
1‑minute calculator (paste into your SOP):
Quick planning table (frozen lanes):
| Muatan (beku) | 24 h | 48 h | 72 h | What to tune |
|---|---|---|---|---|
| Small ≤3 kg | 2.3–3.5 kg | 4.5–7 kg | 7–10 kg | Thin walls? Use upper range. |
| Medium 3–8 kg | 3–4.5 kg | 6–9 kg | 9–13.5 kg | Add 20% in summer. |
| Large 8–15 kg | 4–6 kg | 8–12 kg | 12–18 kg | Consider PU/EPP upgrade. |
Real‑world result: A Bristol chocolatier swapped EPS for EPP with the same dry‑ice weight and cut coolant use ~20% on retest, thanks to lower heat ingress and a clear vent gap at the lid.
Which UK carriers accept dry ice packs UK in 2025?
Use this at booking time (always confirm your account permissions):
| Carrier | Accepts dry ice? | What they say | What it means for you |
|---|---|---|---|
| Royal Mail / Post Office | TIDAK | Dry ice not allowed in UK or international mail. | Don’t send via post. |
| Parcelforce | TIDAK | Es kering (Dan1845) not permitted. | Choose an express DG carrier. |
| DHL Express (UK & EU) | Ya | Accepts UN 1845 as a coolant; per‑shipment surcharge applies. | Budget surcharge; use PI 954 and trained staff. |
| FedEx Express | Ya | Menyediakan 2025 job aids; max 200 kg per paket. | Add AWB entry; ensure label size/placement. |
| UPS (UK) | Ya | Supports dry ice; some lanes require ISC/DG contract. | Book from a DG‑enabled account. |
Booking tip: Confirm the pickup point handles DG; some retail counters do not accept UN1845.
Safety for dry ice packs UK: ventilasi, Co₂, PPE
Bottom line: ventilate, wear insulated gloves and eye protection, and never make the outer box airtight. UK workplace limits for CO₂ exposure are 5,000 ppm (8‑h) Dan 15,000 ppm (15‑min); plan vent paths and avoid storing loose dry ice in small rooms or car boots. Post a one‑page handling SOP near benches.
UK chilled and frozen targets—what should you design to?
Keep dinginkan goods at 0–5 °C best practice (legal maximum 8 °C), and design beku flows around −18 °C. For tight −21 °C control or +2 to +8 °C lanes, PCM beats dry ice on simplicity and avoids DG booking.
When should you pick gel or PCM instead of dry ice packs UK?
Gunakan es kering when the goal is “stay frozen solid.” Use gel/PCM for refrigerated or −21 °C controlled lanes to simplify audits and cut surcharges.
| Pendingin | Typical use | What it does well | What to watch |
|---|---|---|---|
| Es kering (Dan1845) | Frozen foods, −40 °C assets | Ultra‑low temp; no meltwater | Venting & UN1845 labels mandatory. |
| Gel packs (0–5 °C) | Chilled food/meals | Simple, non‑DG | Not for frozen targets. |
| PCM (−21 °C / +5 °C) | Farmasi, gourmet | Holds a narrow band | Validate with logger data. |
Practical tips that actually help
-
Put dry ice on top of the payload; cold air and CO₂ descend through the box.
-
Pre‑freeze the product; dry ice maintains frozen state, it doesn’t fix a warm start.
-
Leave a vent path in the lid; do not tape all around the seam.
-
Plan a +24 h buffer of dry ice for weather and missed‑delivery risk.
Case study: A UK lab shipped frozen reagents Manchester→Dublin in a VIP parcel with 6 kg of dry ice for a 48 h lane. The pack stayed below −20 °C and cleared checks thanks to complete UN1845 marks.
2025 developments & trends for dry ice packs UK
UK parcel volumes rebounded to ~3.9 bn in 2023–24 and continued rising into 2025, so hubs scrutinise labeling more closely. IATA’s 2025 acceptance checklist Dan ADR 2025 clarifications keep UN1845 flows consistent across carriers. Expect more VIP/PCM use for long holds without DG paperwork.

FAQ
Can I send dry ice packs UK with Royal Mail or Parcelforce?
TIDAK. Both prohibit dry ice domestically and internationally. Use a DG‑capable express carrier.
Do I need a Shipper’s Declaration for dry ice?
Not when it’s only a refrigerant for non‑DG contents. You still mark UN 1845, show net kg, and add the AWB entry for air.
What is the max dry ice per package?
Commonly 200 kg per package for air, subject to operator variations. Check your carrier’s job aid.
How much dry ice for a 48‑hour UK journey?
Start with 5–9 kg depending on insulation and ambient heat, then add a +24 h buffer.
Can passengers carry dry ice on aircraft?
Ya, typically up to 2.5 kg per person when used to pack perishables; the bag must vent and be marked. (Check your airline.)
Ringkasan & next steps
Ingat: choose a DG‑capable carrier; label UN1845/Class 9/net kg on a vented shipper; plan 2.3–4.5 kg per 24 h plus a +24 h buffer; and swap to PCM/gel for chilled or −21 °C control. Test once, log temperatures, and tune.
Action plan:
-
Pick the carrier (DHL/FedEx/UPS) and confirm DG handling at your pickup point.
-
Copy the label text Dan AWB line into your workflow.
-
Use the calculator, run two pilots, Dan log temperatures to validate.
