Lead Free at Mico
Beginning from May 2026, all newly installed copper-alloy (brass) products are required to contain less than 0.25% lead, in accordance with updated regulatory standards. Additionally, any tapware installed must not only be lead-free but also dezincification resistant (DZR), ensuring greater safety and durability over time. In preparation for these changes, Mico has already begun transitioning its product range, with the newly compliant items clearly identified by “LF” or “Lead-Free” markings or labels on both packaging and the products themselves. You will notice these already starting to appear in our shelves and bins.
To support this shift and to ensure full compliance with the products that we supply you as of May 1st next year, Mico will stop accepting returns of non-lead-free products from November 1st, 2025. We will have this clearly signposted in our branches to remind you. We suggest that you only take the product that you need for the job. (see FAQ’s below for exceptions to the new regulations)
The production of lead-free products incurs higher manufacturing costs, however Mico is committed to offering these items at the same price as their current equivalents. In most cases, we have been able to keep pricing the same.
Throughout this process, Mico remains dedicated to making the change as seamless as possible, with our team available to provide guidance, support, and clarity every step of the way

- Applies to:
- Tapware, which must also be dezincification resistant (marked as DR or DZR)
- Copper alloy fittings (Brass), valves and fittings used for drinking water

FAQs
Yes. If a building consent was applied for or issued before the 1st May 2026, then the product that was deemed as compliant prior to the 1st May 2026 is fit for purpose.
It has been internationally accepted that when the lead content is less than 0.25%, it is referred to as Lead-Free. Mico was keen to call this Low lead, however, this would have led to confusion as our suppliers are using the internationally accepted term “Lead-Free”.
No, see the table below for guidance on which product types are required to be lead-free and those that aren’t.
