Dry Ice Packs for Shipping Plants: 2025 Guide Updated: August 14, 2025 If you’re evaluating dry ice packs for shipping plants, here’s the bottom line: use them for frozen, non‑viable plant materials; avoid them for live plants and cuttings.

Decide quickly when dry ice packs for shipping plants are appropriate (and when 2–8 °C is wiser). Comply in 2025 with UN1845 labels, venting, and booking/net‑mass requirements.
