Dry ice is classified as a miscellaneous hazard (Class 9) during transportation by DOT and IATA.<\/p>\n<p>Hazards associated with dry ice include the risk of explosion and suffocation in enclosed spaces, as well as the risk of severe cold burn injuries when handled incorrectly. Due to these risks, many carriers restrict or prohibit shipments containing dry ice, and additional surcharges may apply.<\/p>\n<p><span style=\"color: #3366ff;\">HydroFreeze\u2122<\/span> offers a safer alternative. It is FSA certified food safe, non-toxic and not classed as hazardous goods, helping to simplify frozen shipping without the need for specialist handling or HAZMAT labelling.<\/p>\n<h2>Why not use regular water or gel ice packs?<\/h2>\n<p>Standard water or gel ice packs phase change at 0\u00b0C, meaning they are suitable for chilled or refrigerated shipments, but not for frozen goods. Once packed, they stabilise around 0\u00b0C as they melt, which is insufficient for maintaining frozen product temperatures.<\/p>\n<p><span style=\"color: #3366ff;\">HydroFreeze\u2122<\/span> products have a phase change point of <strong>-21\u00b0C<\/strong>, allowing them to hold frozen temperatures as they transition from solid to liquid and support frozen product integrity inside insulated packaging.<\/p>\n<p><strong><u>Recommended pre-conditioning of <span style=\"color: #3366ff;\">HydroFreeze\u2122<\/span><\/u><\/strong><br \/>\n<span style=\"color: #3366ff;\">HydroFreeze\u2122<\/span> products should be pre-conditioned in a sufficiently powerful freezer capable of maintaining temperatures below <strong>-25\u00b0C<\/strong>.
