ISO 18603:2013

Overview

ISO 18603:2013 - Packaging and the environment - Reuse defines what it means for packaging to be considered reusable and lays out the procedures for assessing and documenting that claim. The standard specifies requirements for packaging design, inspection and the supporting reuse systems (closed loop, open loop, hybrid). Application rules are provided by ISO 18601, and vocabulary reference is in ISO 21067.

Key topics and technical requirements

• Core definitions: reuse, reusable packaging, trip, rotation, systems for reuse, auxiliary product, reconditioning, supplier, emptier.
• Methodology: assessment confirmation and background conditions describing how design, reconditioning capability and market systems determine reusability.
• Initial requirements: suppliers (packer, filler, emptier or others) must demonstrate packaging is capable of reuse and that a reuse system exists where the packaging is placed on the market.
• Verification procedure (summarized): establish and record the intention to reuse and verify that packaging:
  • is designed for a number of trips/rotations in predictable use conditions;
  • can be emptied/unloaded without damage that prevents viable repair;
  • can be reconditioned to restore function (see Annex B);
  • can be refilled without risk to product integrity or health/safety;
  • has reconditioning processes managed with environmental considerations;
  • operates within a reuse system compliant with Clause 6 specifications;
  • when no longer reusable, can be recovered under ISO 18604 / ISO 18605 / ISO 18606.
• Reuse system types: requirements and criteria are given for closed loop, open loop, and hybrid systems (see Clause 6 and Annex A for concepts).
• Supporting documentation: Annex B lists elements of reconditioning systems; Annex C defines the content and format for recording assessment results.

Applications and who uses it

ISO 18603 is intended for stakeholders involved in packaging lifecycle and supply chains:

• Packaging designers and manufacturers - to design for repeat trips and reconditioning.
• Packers, fillers and suppliers - to verify and declare reusability of products they place on the market.
• Retailers, logistics and pooling operators - to implement closed, open or hybrid reuse systems.
• Sustainability managers and compliance teams - to support environmental claims and reporting (note: ISO 18603 covers technical reuse aspects; product labeling claims may require ISO 14021 compliance).
• Third‑party auditors and certification bodies - to assess conformity and document evidence.

Related standards

• ISO 18601 - General requirements for using ISO packaging/environment standards (application procedure).
• ISO 21067 - Packaging vocabulary.
• ISO 18604 / ISO 18605 / ISO 18606 - Recovery routes (material recycling, energy recovery, organic recycling).

Using ISO 18603 helps organizations reduce environmental impact, enable circular packaging strategies and provide documented, auditable evidence that packaging is genuinely reusable.
