How do I know when I need to change a GTIN on a construction product?

The Global Trade Item Number (GTIN) serves as a comprehensive global supply chain solution designed for the identification of any trade item that requires pricing, ordering, or invoicing at any point within the supply chain, necessitating the retrieval of predefined information. These standardised rules, outlined in the Global Trade Item Number Management Standard, apply universally, regardless of the industry or type of trade item.

For the generic GTIN management standard, see these FAQs for more details:

I’ve changed a product a little bit. Can I keep using its GS1 GTIN™?

Does a formulation change in a product require a new GTIN?

Can a GTIN be re-used?

For sector-specific instances and guidance on when to update the GTIN for construction products, please refer to the Global Trade Item Number Management Guideline for Construction Products
