What We Can Help With

Tell Us What You’re Shipping

Picking a heat pack duration is easier when we know what is in the box and how far it is going. If you tell us the product, the route, and roughly how long transit takes, we can point you at a configuration that makes sense.

  • Choosing a duration for live animals, plants, aquatics, beverages, perishables, or cosmetics
  • Packaging questions — insulation, airflow, void fill, and where to position the pack
  • Wholesale and bulk pricing for higher volumes
  • Existing orders — tracking, changes, returns, or something that arrived damaged

Looking for a quick answer instead? Our Frequently Asked Questions covers heat duration, activation time, safe use around live animals and plants, and carrier acceptance. The Cold-Weather Shipping Guide goes deeper on freeze thresholds by industry.
