Bathroom FAQ
What's the difference between C46500 and CW617N brass?+
C46500 is the lead-free, NSF/ANSI 372-compliant export grade required for US potable-water products. CW617N is cheaper leaded brass used for uncertified markets. Switching to C46500 is the single most important US-compliance decision — and we default to it.
Do you make the filtered shower cartridges?+
Yes — KDF-55, Vitamin C, multi-stage media, at factory cost. The refill becomes a built-in subscription for your brand.
What's the MOQ and lead time?+
50–200 pieces per model. Sampling 7–15 days, bulk production 25–35 days.
Which finishes can you do?+
Chrome, matte black, brushed & champagne gold, gunmetal, brushed nickel and custom colour matching — all in durable PVD, 10–20× more scratch-resistant than electroplating.
