Intro: If you’re asking how to pack with dry ice for shipping, here’s the short answer: pre‑freeze products, use a vented insulated shipper, surround the payload with dry ice, dan Mark Dan1845 with net kilograms and a Kelas 9 label for air. Plan roughly 5–10 lb per 24 jam plus a buffer to ride out delays.

How to pack with dry ice for shipping step‑by‑step?
Direct answer: Pre‑freeze to 0 °F (–18 °C), use a rigid outer box with an EPS/PU/VIP liner, keep vents open, place dry ice around (not just under) the payload, and mark “Dry Ice/Carbon dioxide, padat,” UN 1845, and net kg; add Class 9 untuk udara. Size 5–10 lb per day of transit and add a 24‑hour buffer.
Why this works: Dry ice becomes CO₂ gas; your packaging must vent to avoid pressure build. Air shipments follow IATA PI 954 (kemasan ventilasi, AWB entries, ≤200 kg/package, Kelas 9). Tanah (KITA.) still requires UN 1845 proper name and Kg net on the carton, and the packaging must release gas. Carriers often align with IATA for smoother acceptance.
How much dry ice per day for frozen shipments?
Plan 5–10 lb per 24 jam dalam pengirim yang terisolasi dengan baik, then add margin for heat and delays. Better insulation (thick EPS, Pur, atau VIP) lowers daily burn‑off; fuller loads reduce warm air pockets. Convert to kilograms for labels (kg = lb × 0.4536).
Sizing Snapshot | Baseline (lb) | With Buffer (lb) | Apa artinya bagimu |
---|---|---|---|
24 H, standard EPS | ~8 | ~10 | Weekend risk? Round to 12 lb. |
48 H, thick EPS | ~16 | ~20 | Fewer hot spots; steadier temps. |
72 H, VIP | ~22 | ~26 | VIP cuts total ice mass. |
Practical tips and quick wins
-
Hot two‑day route: Upgrade to 1.5–2 in insulation or VIP; then add 20% extra dry ice.
-
Food contact: Use a barrier so ice never touches food directly; avoid sealed plastic bags for the dry ice.
-
Placement: “Sandwich” the payload—base blocks + sides + top pellets—to eliminate warm pockets.
Kasus dunia nyata: A DTC pastry brand switched from pellets‑only to blocks at the base plus pellets on the sides/top and added a 20% summer buffer; “soft deliveries” fell 38% and on‑temp arrivals jumped.
How to pack with dry ice for shipping: Label & documents?
Direct answer: Mark “Dry Ice/Carbon dioxide, padat,” UN 1845, net dry‑ice mass in kilograms, and apply the Class 9 label for air. On the airway bill add: “UN 1845, Es kering, n × kg.” IATA PI 954 caps 200 kg/package and requires vented packaging.
Expanded guidance: U.S. tanah (HMR/PHMSA) still requires proper name, Dan1845, Kg net, dan ventilasi; a Class 9 label isn’t mandated by HMR, though carriers may harmonize to IATA. FedEx job aids also specify readable minimum type sizes and 100×100 mm Class 9 diamonds; affix labels on the outer box, not inside sleeves.
Copy‑ready templates (keep with your SOP)

Teks AWB:
UN 1845, Dry Ice, __ packages × __ kg
-
Carton marks (udara): Proper name, Dan1845, Kg net, Kelas 9; shipper/consignee addresses.
-
Carton marks (U.S. tanah): Proper name, Dan1845, Kg net; vented package (no airtight systems).
Which packaging helps you pack with dry ice for shipping efficiently?
Direct answer: Use a rigid corrugated outer with an insulated insert (EPS/PUR for 24–72 h; VIP for longer or riskier lanes). Never make the system airtight—CO₂ must escape.
Expanded: EPS is cost‑effective for 1–2 days; thicker EPS/PUR extends hold time; VIP achieves multi‑day performance with less refrigerant and weight, reducing claims and volumetric charges—ideal for international or hot lanes.
VIP vs foam: when does “premium” pay back?
Detail: VIP systems deliver 96–240+ hours performance at lower dry‑ice mass. If your lanes face delays or the payload is high‑value, VIP often lowers total landed cost through weight savings and fewer reships.
Kemasan | Typical thickness | Typical duration | Apa artinya bagimu |
---|---|---|---|
EPS (busa) | 1–1.5 in | 24–48 h | Cheapest; add buffer in heat. |
Thick EPS / Pur | 1.5–2 in | 48–72 h | Longer hold; less ice mass. |
Panel VIP | 0.4–0.8 in | 96–240 h | Thinnest walls; best stability. |
How to pack with dry ice for shipping across carriers?
Direct answer: For FedEx/UPS air, mengikuti IATA PI 954 (kemasan ventilasi, Dan1845, Kelas 9, Teks AWB). USPS allows ≤5 lb dry ice in domestic air mail with specific packaging rules; international mail with dry ice is prohibited.
Expanded: Expect acceptance checks at counters. Getting AWB text and Kg net perfect speeds acceptance. Many integrators harmonize ground handling to the air standard to reduce errors.
Cold‑chain compliance beyond how to pack with dry ice for shipping
Direct answer: Document your temperature controls, train staff, and retain records to satisfy FSMA Sanitary Transportation requirements. Define arrival targets (MISALNYA., 0 °F for frozen foods), sizing logic, and verification (data loggers or arrival checks).
Simple checklist: Procedures; pelatihan (PPE, ventilasi, pelabelan); records (lane plans, logger files, corrective actions). Build this into your SOP and audits.
2025 developments and trends in dry‑ice shipping
Trend overview: Carriers tightened acceptance against PI 954 checklists (MISALNYA., explicit 200 kg/package and venting). USPS updated Publication 52 di dalam 2025; VIP and reusables are rising to reduce refrigerant weight and claims. Expect faster counter acceptance when labels and AWB entries are exact.
Kemajuan terbaru sekilas
-
VIP adoption accelerates: Higher hold times with less ice reduce cost and damage.
-
Reusable programs expand: Lower waste and stable thermal profiles for recurring lanes.
-
Job‑aid clarity improves: Label sizes, text heights, and “no sealed bags” called out plainly.
Wawasan pasar: Cold‑chain packaging demand keeps growing with DTC frozen foods and biologics. Upgrading to thicker liners or VIP plus smarter sizing typically cuts refunds and re‑ships—an ROI many shippers now measure in weeks, not quarters.
FAQ
Q1: Do I need a Shipper’s Declaration if dry ice is the only DG?
Biasanya TIDAK when contents are non‑DG; you still need UN 1845, Kg net, Kelas 9 (udara), and correct AWB text. Verify operator variations.
Q2: How much dry ice should I plan per day?
Start with 5–10 lb per 24 jam, then add a 24‑hour buffer for delays; better insulation reduces the amount.
Q3: What size should the Class 9 label be?
Minimum 100 × 100 mm; keep borders clear and don’t write inside the diamond.
Q4: Any carrier‑specific gotchas?
USPS air caps at ≤5 lb per mailpiece and bans international dry‑ice mail. FedEx/UPS enforce PI 954 acceptance details at counters.
Q5: What mistakes trigger delays?
Airtight packages, missing Kg net, marking pounds instead of kilograms, thin insulation, and skipping top/side coverage.
Ringkasan & Rekomendasi
Ingat: How to pack with dry ice for shipping comes down to vented insulated packaging, side/top coverage, and correct Dan1845 + Kg net marking (Kelas 9 untuk udara). Rencana 5–10 lb/day plus buffer; upgrade insulation on hot or long lanes; and keep FSMA documentation tidy.
