What is a shipping dry ice pack sheet (COMPENSACIÓN) y por qué importa?

Respuesta directa
A shipping dry ice pack sheet is a one‑page, POE paso a paso that tells packers how to assemble, etiqueta, and document each UN 1845 shipment. It shows the net hielo seco (kilos) to load, colocación de etiquetas (Clase9, 100 mm), and the records to capture so your box passes acceptance the first time.

Explicación expandida
Think of it as a recipe card: PPE → box/liner → payload → dry ice placement → vent → mark “Dry Ice/Carbon dioxide, sólido,"Y 1845, Kg neto → 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)

Detalles

Nombre de envío adecuado: Hielo seco o Dióxido de carbono, sólido
UN 1845 and peso neto de hielo seco en kilogramos en la caja exterior
Etiqueta de clase9 (≥100 mm) en la misma cara cuando el espacio lo permite
Packaging that permits CO₂ to vent (no airtight closures)
Shipper/consignee names and addresses (no dentro del diamante)

Label/Marking	Requisito	Dónde	Por qué te importa
Nombre de envío adecuado	"Hielo seco" o "dióxido de carbono, sólido"	Caja exterior	Mirrors IATA acceptance checks
Y 1845	6–12 mm text height (by package capacity)	Misma cara cuando sea posible	Fast visual confirmation
Hielo seco neto (kilos)	Kilograms only	Near shipping name	Required for acceptance and booking
Diamante de clase9	100 × 100 mm minimum	Same face if space	Meets size rule and avoids relabel

Consejos prácticos & sugerencias

carriles aéreos: Align your sheet to Aquí está PI954 and any operator variations.
A NOSOTROS. ground/water: Keep 49 CFR 173.217 venting language visible; vessel moves need special markings (“ADVERTENCIA CO₂ SÓLIDO (Hielo seco)").
Global ops: Localize by region and mirror carrier acceptance job‑aids.

Caso en punto: A biotech added a bold “Hielo seco neto (kilos)” 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?

Respuesta directa
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. Usar ISTA 7D (24/48/72 H) o 7mi profiles as guardrails before rollout.

Explicación expandida
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 (p.ej., personaje) 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 kilos into your sheet.

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

Detalles

24 H carril, EPS + 6 L payload: 1.5–2,5 kilos
48 H carril, EPS + 6 L payload: 3–4 kg
72 H carril, personaje + 6 L payload: 4–6 kg
Validate with a chamber or ambient test and a logger; adjust ±15%.

Test Type	Perfil	Pass Criterion	What you capture
Chamber	ISTA 7D 48 h Summer	Payload stays ≤ max temp	Kg neto, colocación, 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

90‑second self‑check (interactivo)

Can you point to hielo seco neto (kilos) on the box in 3 s?
Es el Clase9 etiqueta ≥100 mm, same face as the name when possible?
Does your shipper Viento de 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)?

Respuesta directa
Mark the box with “Dry Ice/Carbon dioxide, sólido", Y 1845, y net kg, aplicar un 100 mm Class 9 etiqueta, keep addresses outside the diamond, and ensure the packaging vents. Usar el IATA 2025 dry‑ice acceptance checklist during handoff.

Explicación expandida
Carrier job‑aids now call out minimum text sizes for UN 1845 and emphasize keeping the net kilos legible, not scribbled inside the diamond. If you overpack, mark the overpack total (kilos). 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

El 2.5 kg figure you may see applies to equipaje de pasajeros, 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?

Respuesta directa
Your packaging must vent CO₂ para evitar la acumulación de presión. For vessel moves, add “WARNING CO₂ SOLID (Hielo seco)”/“NO GUARDAR DEBAJO DE CUBIERTAS"; para el aire, marcar masa neta (kilos) on the outside and coordinate with the operator.

Explicación expandida
Incluir un 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 y NIOSH 40,000 ppm IDLH límites.

Instantánea de seguridad (CO₂ exposure long‑tail)

OSHA PEL: 5,000 PPM (8-H dos)
Nioh IDHL: 40,000 PPM
Keep rooms/vehicles ventilated; never block vent paths.

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

Respuesta directa
Qualify packs with ISTA 7D (24/48/72 H) y considerar 7mi profiles when you need parcel‑environment realism. Correr summer first, entonces invierno, then a live pilot with loggers.

Explicación expandida
Locking the Kg neto on your sheet should always follow a passed test with margin. Use the same payload, expedidor, and pre‑condition, and capture time‑to‑warm y too‑cold risks so you’re ready for audits and seasonal swings.

“Dry ice pack sheets” (gel) VS. Hielo seco realmente seco: cual deberías usar?

Respuesta directa
Gel “dry ice pack sheets” are not dry ice. They freeze near –20 °C, son not regulated as dangerous goods, and suit chilled/frozen ranges (p.ej., 2–8 °C or ≤0 °C). Usar Hielo seco realmente seco (–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.)

Explicación expandida
Para vacunas y productos biológicos, 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 breve: gel para frío, hielo seco para ultracongelados + regulado, y always validate.

Real‑world rule of thumb

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