Initial shipment had one non-conforming heat — supplier resolved with replacement and credit
We ordered 190 metric tons of HRB400 rebar in 12 mm and 18 mm diameters for foundation work in Florida. The majority of the shipment — approximately 175 tons — was fully compliant with GB/T 1499.2-2018, with yield strength and elongation within spec. However, one heat of the 18 mm bars showed elongation of 14.8%, below the ≥16% minimum. We raised the non-conformance immediately with supporting third-party lab data. The supplier acknowledged the issue within 48 hours, arranged a replacement shipment for the affected quantity, and issued a partial credit for the delay caused. The resolution process was handled professionally. Upgraded to a higher rating would require consistent first-shipment quality across all heats.
