Initial Shipping Delay Resolved — Product Quality Was Fine
Ordered 6 tons of A210 Grade C, 76.2mm x 6.35mm WT, for a heat exchanger project. The tubes themselves met all ASTM requirements — no complaints on material quality or documentation. However, the original delivery was delayed by about 10 days beyond the quoted lead time due to a mill scheduling issue. Kuaima's team communicated the delay proactively and offered a small discount on the next order to compensate, which we appreciated. Product was good once it arrived, so we'd order again with a longer planning buffer.
