Yet, for many innovators, shipping temperature-sensitive materials is an infrequent, critical requirement rather than a daily routine. Building a permanent **Dangerous Goods (DG)** infrastructure is rarely economical for ad hoc needs. Jet Worldwide bridges this gap, offering a turnkey solution for **small, compliant dry ice shipments** from Montreal to the UK, EU, USA, and beyond—without requiring you to become a logistics specialist. ## The Science of Dry Ice Shipping (UN1845) Dry ice (solid carbon dioxide) is the gold standard for ultra-low temperature transit. Sublimating at **-78.5°C**, it provides a stable environment for materials that must remain deeply frozen. ### Why Dry Ice for Montreal Exporters? - **Extended Thermal Hold:** Maintains sub-zero status for 72+ hours. - **No Liquid Residue:** Sublimates directly to gas, protecting packaging. - **Courier Compatibility:** Optimized for international express networks. - **Scale-on-Demand:** Ideal for one-off validation or R&D samples. ![Jet Worldwide logistics vehicle serving Montreal's life science hubs](https://www.jetworldwide.com/hs-fs/hubfs/jet-van-city-route-2024.webp?width=340&height=221&name=jet-van-city-route-2024.webp) Reliable temperature-controlled transport across Greater Montreal. --- ## Who Requires Managed Dry Ice Shipping in Montreal?

For **2026 international lanes**, we recommend the following conservative benchmarks: | Dry Ice Quantity (kg) | Typical Hold Time (Hours) | Recommended Destination | | --- | --- | --- | | 2–3 kg | 24–36 Hours | Eastern USA / Ontario / Quebec | | **4–6 kg** | **48–72 Hours** | **UK, EU, Western USA** | | 7–10 kg | 72–96 Hours | Asia-Pacific / Remote Destinations | **Estimates based on high-density EPS insulation and average ambient conditions.* ## Navigating Courier DG Acceptance International express couriers (FedEx, UPS, DHL) only accept dry ice when packaging and paperwork are flawless. Jet Worldwide ensures your shipment meets every threshold: - **Vented Packaging:** Essential to prevent CO2 pressure build-up. - **Net Weight Accuracy:** Required for aircraft weight and balance safety. - **Class 9 Labeling:** Distinct markers for UN 1845 materials. ## Related Resources - [Commercial invoice for international shipping](https://www.jetworldwide.com/blog/preparing-invoices-for-customs-clearance-and-cci) - [Declared value, CIF & valuation for international shipping](https://www.jetworldwide.com/blog/declared-value-cif-and-valuation-for-international-shipping) - [When to include a certificate of origin](https://www.jetworldwide.com/blog/certificate-of-origin-explained) - [What is an HS code?
