The cork and wine sectors have been working together for decades with the commitment to offer the maximum guarantees to the final consumer, which goes through standardization both at national and international level with the alliance with organizations such as ISO (International Organization for Standardization) which deals with ensuring the quality, safety and efficiency of the products it regulates.

The Institut Català del Suro Foundation is part of the International Technical Committee ISO/TC 87 Cork which ensures standardization in the field of cork, both of the raw material and of the products manufactured and elaborated from cork. 6 countries actively participate in this working group (Argentina, France, Portugal, Russia, Turkey and Spain) and 15 countries are present as observers. The ICSuro Foundation leads the Spanish delegation.

This technical committee contributes with 48 standards to the fulfillment of the Sustainable Development Goals in accordance with the commitment to build resilient infrastructures, promote inclusive and sustainable industrialization and promote innovation. At its biannual meetings, new rules are worked on, as is currently being done with the rule-guide on the sustainable management of cork. Other existing ones relating to chemical, physical or sensorial analyzes and sampling are also reviewed and updated. For this last section, the ICSuro acts as the secretariat until at least 2024.

Corks are the only closures that have their own rules with test methods and specifications related to sensory, physical, chemical or microbiological aspects.
