1) Was "dry ice packing peanuts”Bedeutet wirklich

Direkte Antwort: It’s the combination aus Trockeneis (to hold temperature) and packing peanuts (to remove dead air and prevent product movement) inside an isoliert, entlüftet Absender. Regulations require CO₂ to vent; packages must be marked Und 1845 und zeigen die net mass of dry ice (kg).

Air waybill text: Many university and carrier job‑aids require wording similar to: „Trockeneis, 9, UN1845, number of packages X, net weight in kilograms.” Check your operator’s variation.

2) Der 2025 Regeln, die Sie erfüllen müssen (Iata, PUNKT, USPS)

• IATA DGR 66th ed. (2025) + Addendum 1 (Apr 30, 2025): Dry ice shipped without other DG uses the Acceptance Checklist for Dry Ice (Wenn die Erklärung eines Versenders nicht erforderlich ist). Keep state/operator variations in mind.

• PUNKT (UNS) 49 CFR §173.217: Packaging must CO₂ -Freisetzung erlauben; markieren Und 1845 und die Netzmasse of dry ice on the package.

• USPS Publication 52, Instr. 9A (domestic mail): Specific limits/packaging for dry ice; follow §349 plus 9A details for air pieces. International mail with dry ice is prohibited.

Notiz: Some acceptance job‑aids and EHS guides cite 200 kg max net dry ice per package under PI 954; operators may set stricter limits—always check carrier variations.

3) Schritt -für -Step -Packout (Prüfungsrede)

1. Pick the shipper: EPS/EPP cooler (VIP for long lanes) nested in a corrugated outer.

2. Prep the payload: Bag/seal anything that may leak or thaw.

3. Load dry ice: Ort around and above the product (Tun nicht wrap or seal dry ice); the package must Entlüftung.

4. Hohlräume füllen: After loading dry ice, eliminate remaining air space with packing peanuts or crumpled paper to immobilize contents and slow sublimation.

5. Schließen & markieren: Anwenden Klasse 9 Etikett, Und 1845, NET Dry -Ice Kg, and shipper/consignee addresses to a vertikale Seite panel; complete air waybill text.

Für die Spitze (acceptance speed): FedEx job‑aids highlight UN‑number mark size guidance (≥ 12 mm bei der Packungskapazität >30 kg). Check the current job‑aid for your region.

4) Wie viel Trockeneis? Schneller Schätzer

Planning rule of thumb: 5–10 lb (2.3–4,5 kg) pro 24 H for small insulated shippers (validate on your lane; add a delay buffer).

Schätzer (include a buffer):

• Wählen days = ceil(hours/24)

• Fangen Sie an 3.6 kg/day (midpoint) × cooler factor (0.6 good / 1.0 Durchschnitt / 1.4 poor)

• Hinzufügen 20% Verzögerungspuffer.

Beispiel: 48 H, average cooler → 3.6×2×1.0 = 7.2 kg → +20% ≈ 8.6 kg Trockeneis.

5) Which peanuts: EPS vs. biodegradable vs. paper

Why fill voids at all? Dead‑air space speeds sublimation; removing it helps retain refrigerant and stabilizes temperature.

6) CO₂ safety: Belüftung, exposure limits, Beschilderung

• Gasvolumen: 1 lb dry ice → ~8.3–8.7 ft³ CO₂ at ambient conditions—plan room ventilation and vehicle airflow accordingly.

• Expositionsgrenzen: OSHA PEL 5,000 ppm (8-H zwei); Niosh Stel 30.000 ppm, Idlh 40.000 ppm. Use monitors in small staging rooms.

• Do not airtight‑seal inner liners or coolers; Verpackung muss allow CO₂ to vent.

7) QA: Etiketten, documents, acceptance checks

• Air waybill (when no DG declaration): Include “Dry ice, 9, UN1845, number of packages X, net weight in kilograms.”

• Acceptance checklist: Use IATA’s Checkliste zur Akzeptanz von Trockeneisakzeptanz and your carrier’s job‑aid at tender.

• Common errors: Missing net kg, labels on top/bottom panels, or covering marks with tape. Follow carrier job‑aids for placement/size.

Q3. Can I use biodegradable peanuts with dry ice?
Yes—just keep them trocken. Starch‑based loose‑fill is water‑soluble and can slump under condensation; choose EPS or paper for humid routes.
