ISO 22982-1:2021

Overview

ISO 22982-1:2021 - Transport packaging - Temperature-controlled transport packages for parcel shipping - Part 1: General requirements - defines the general requirements for packaging and containers used in temperature-controlled parcel shipping. The standard focuses on ensuring safe storage and distribution of temperature-sensitive products through the parcel (small-package) cold chain. It specifies classifications, dimensional guidance, material considerations (including phase changing materials), performance metrics and labelling. The scope emphasizes general packaging requirements; note that it clarifies the remit around safety and sanitation while also providing handling and dry-ice guidance.

Key topics and technical requirements

• Classification of systems: Defines passive (insulation-based) and active (powered cooling/heating) temperature-controlled packaging systems and guidance for selecting the appropriate type.
• Phase changing materials (PCM): Requirements for PCM use, including safety (non-toxicity), leakage prevention, and documentation of material properties and expected performance.
• Packaging dimensions and tolerances: Recommends plan-view dimensions based on ISO 3394 and thickness tolerances aligned with ISO 4898.
• Thermal performance: Requirements for maintaining temperature consistency, measurement of thermal resistance and container capacity (e.g., methods for capacity measurement using water displacement principles).
• Safety and handling: Practical precautions for handling containers and coolants - including dry ice labeling, ventilation and handling to avoid frostbite or asphyxiation.
• Mechanical and surface performance: Tolerances for weight (±3% nominal), acceptable surface condition, and stacking considerations to avoid collapse (references tests in related parts).
• Labelling and symbols: Positioning and general labelling requirements for identification of temperature-controlled packages.

Practical applications and who uses this standard

ISO 22982-1 is directly applicable to organizations involved with small-parcel cold chain distribution:

• Packaging designers and manufacturers (insulated boxes, VIP panels, PCM packs)
• Cold chain logistics providers and parcel carriers offering temperature-controlled services
• E‑commerce retailers shipping perishables or pharmaceuticals
• Third‑party fulfillment and last‑mile delivery operators
• Test laboratories and quality assurance teams validating package thermal performance
• Standards bodies and procurement teams specifying packaging requirements

Adoption helps ensure consistent thermal protection, safer handling of coolants (e.g., dry ice), and clearer communication among stakeholders in parcel-based cold chains.
