BUILD 2025: Non-conforming products

Non-conforming products

Non-conforming products can be found across all areas of construction, right from the roof to the smallest bolts and screws.

Your builder or trade contractor must ensure that all materials and products they use adhere to the National Construction Code (NCC).

IMPORTANT: JUST BECAUSE YOU CAN BUY IT, DOESN’T MEANT IT’S COMPLIANT

Retailers don’t have to comply with the NCC, so just because a product is available to buy, even from a well-known Australian retailer, doesn’t guarantee it meets the required standards.

If you decide to buy materials on your own, your builder or trade contractor may ask for the following proof of compliance with the NCC:

• A current ‘Certificate of Conformity’ issued under CodeMark or WaterMark certification

• A certificate from an engineer or another qualified professional

• A report from a registered testing authority recognised by NATA.
