What is a shipping dry ice pack sheet (AMADOUER) and why does it matter?

Réponse directe
A shipping dry ice pack sheet is a one‑page, step‑by‑step SOP that tells packers how to assemble, étiquette, and document each UN 1845 shipment. It shows the net glace carbonique (kg) to load, label placement (Classe9, 100 MM), and the records to capture so your box passes acceptance the first time.

Expanded explanation
Think of it as a recipe card: PPE → box/liner → payload → dry ice placement → vent → mark “Dry Ice/Carbon dioxide, solide,” UN 1845, Kg net → record time and initials. The sheet maps your QA plan to the Iata 2025 dry‑ice acceptance checklist, and for U.S. moves it echoes 49 CFR173.217 venting and marking basics. That alignment is what keeps surprises off the dock.

The minimum your sheet must include (PI 954 long‑tail)

Détails

Nom d'expédition approprié: Glace sèche ou Carbon dioxide, solide
UN 1845 and net dry ice weight in kilograms on the outer box
Étiquette de classe9 (≥ 100 mm) on the same face when space allows
Packaging that permits CO₂ to vent (no airtight closures)
Shipper/consignee names and addresses (not inside the diamond)

Label/Marking	Exigence	Où	Why it matters to you
Nom d'expédition approprié	“Dry Ice” or “Carbon dioxide, solide"	Outer box	Mirrors IATA acceptance checks
Et1845	6–12 mm text height (by package capacity)	Same face when possible	Fast visual confirmation
Net dry ice (kg)	Kilograms only	Near shipping name	Required for acceptance and booking
Diamant de classe9	100 × 100 mm minimum	Same face if space	Meets size rule and avoids relabel

Conseils pratiques & suggestions

Air lanes: Align your sheet to Voici pi954 and any operator variations.
NOUS. ground/water: Keep 49 CFR 173.217 venting language visible; vessel moves need special markings (“WARNING CO₂ SOLID (DRY ICE)»).
Global ops: Localize by region and mirror carrier acceptance job‑aids.

Case in point: A biotech added a bold “Net dry ice (kg)” line and a 4‑point label check to its sheet. Acceptance failures dropped to near zero in two weeks across three hubs, eliminating rework and fees.

How much dry ice should your shipping dry ice pack sheet specify?

Réponse directe
Start from your last passing test at the target duration, then add 10–25% for hotter lanes or bigger payloads, and confirm with a quick ambient test and a data logger. Utiliser ISTA 7D (24/48/72 H) ou 7E profiles as guardrails before rollout.

Expanded explanation
For most 2‑day lanes with a 6 L payload in EPS, 3–4 kg dry ice is a practical starting point; for 72 h, use higher‑retention shippers (Par exemple, VIP) and raise load. Run one chamber test against a 48 h summer curve and one winter curve to check “too cold” risk, then lock the kg into your sheet.

Quick lane‑based estimator (how much dry ice for 48‑hour shipping?)

Détails

24 H lane, PSE + 6 L charge utile: 1.5–2.5 kg
48 H lane, PSE + 6 L charge utile: 3–4 kg
72 H lane, VIP + 6 L charge utile: 4–6 kg
Validate with a chamber or ambient test and a logger; adjust ±15%.

Test Type	Profile	Pass Criterion	What you capture
Chamber	ISTA 7D 48 h Summer	Payload stays ≤ max temp	Net kg, placement, time‑to‑warm
Chamber	ISTA 7D 48 h Winter	Payload stays ≥ min temp	Too‑cold risk, need for buffers
Live lane	Actual route	Inside label range	Real‑world variability vs chamber

Can you point to net dry ice (kg) on the box in 3 s?
Is the Classe9 étiquette ≥ 100 mm, same face as the name when possible?
Does your shipper vent CO₂ per 49 CFR 173.217?
Did you log seal time, initials, and logger ID?

PI 954 labeling checklist for your shipping dry ice pack sheet (what to write and where)?

Réponse directe
Mark the box with “Dry Ice/Carbon dioxide, solide", Et1845, and net kg, apply a 100 mm Class 9 étiquette, keep addresses outside the diamond, and ensure the packaging vents. Utiliser le Iata 2025 dry‑ice acceptance checklist during handoff.

Expanded explanation
Carrier job‑aids now call out minimum text sizes for UN 1845 and emphasize keeping the net kg legible, not scribbled inside the diamond. If you overpack, mark the overpack total (kg). Some operators also request the net kg during booking to stay within aircraft carbon‑dioxide limits—add a booking line to your SOP.

Don’t mix up baggage allowances with cargo rules

Le 2.5 kg figure you may see applies to passenger baggage, not most cargo shipments. Cargo is governed by PI 954 and operator limits, with some carriers requesting net kg at booking.

49 CFR 173.217 venting: what must your shipping dry ice pack sheet say?

Réponse directe
Your packaging must vent CO₂ to prevent pressure build‑up. For vessel moves, add “WARNING CO₂ SOLID (DRY ICE)”/“DO NOT STOW BELOW DECKS»; pour l'air, mark net mass (kg) on the outside and coordinate with the operator.

Expanded explanation
Include a bold “VENT” reminder in the closing step, and train drivers not to store boxes in sealed trunks. For team safety, align training to OSHA 5,000 ppm TWA et NIOSH 40,000 ppm IDLH limits.

Safety snapshot (CO₂ exposure long‑tail)

OSHA PEL: 5,000 ppm (8-H deux)
NIOSH IDLH: 40,000 ppm
Keep rooms/vehicles ventilated; never block vent paths.

Test & validate your shipping dry ice pack sheet (ISTA 7D/7E quick path)

Réponse directe
Qualify packs with ISTA 7D (24/48/72 H) and consider 7E profiles when you need parcel‑environment realism. Run summer first, alors hiver, then a live pilot with loggers.

Expanded explanation
Locking the Kg net on your sheet should always follow a passed test with margin. Use the same payload, expéditeur, and pre‑condition, and capture time‑to‑warm et too‑cold risks so you’re ready for audits and seasonal swings.

“Dry ice pack sheets” (gel) contre. vraie glace sèche: which should you use?

Réponse directe
Gel “dry ice pack sheets” are not dry ice. They freeze near –20 °C, sont not regulated as dangerous goods, and suit chilled/frozen ranges (Par exemple, 2–8 °C or ≤0 °C). Utiliser vraie glace sèche (–78,5 ° C) for deep‑frozen lanes or where long hold times are needed—then follow PI 954/49 CFR rules. (Industry practice; regulatory sources above.)

Expanded explanation
For vaccines and biologics, health authorities caution not to store vaccines on dry ice because it can over‑cool. Use validated fridges/freezers and data loggers for routine storage or emergency moves. En bref: gel for chilled, dry ice for deep‑frozen + regulated, et always validate.

Real‑world rule of thumb

Chilled (2–8 ° C): Gel sheets/PCM, validate with 7E
Frozen (≤0 °C to –20 °C): Gel + high‑retention shipper or small dry‑ice top‑up
Deep‑frozen (≤–50 °C): Dry ice with PI 954 compliance
