Code of Practice - Packaging of Dangerous Substances for Carriage by Road - No.1 Organic Peroxides

Sep 21, 2026

Provides practical packaging categories and handling definitions for organic peroxides when conveyed by road, aligned with statutory controls under the Petroleum (Organic Peroxides) Order and the 1973 packaging regulations and related Northern Ireland instruments. Specifies how packaging strength and closure effectiveness must match product characteristics, introduces alternative packaging forms and mixture-based category selection, and references acceptable international air transport packaging standards for restricted articles.

FAQs

What is the purpose of the Code of Practice for organic peroxides in road carriage?

To supplement statutory requirements by ensuring the packaging used for organic peroxides is suited to the product and strong enough for normal transport conditions.

How are packaging categories determined for technical purity or solvent/water mixtures?

The Code assigns a packaging category by substance and describes which solution or mixture compositions (including percentage thresholds) correspond to each recommended packaging type.

What does “effectively closed” and “liner” mean in this Code?

“Effectively closed” means a liquid-tight closure that prevents liquid escape under normal transport; a “liner” is a snug, flexible inner receptacle designed to prevent interaction with the outer receptacle and contents.
