How Is KWZ Classified?

Prosthesis, Hip, Constrained, Cemented Or Uncemented, Metal/Polymer is FDA product code KWZ, Class 2, 21 CFR 888.3310.

What Does It Take to Sell It in the United States?

A 510(k) premarket notification is required before it is sold in the United States: the applicant shows the device is substantially equivalent to one already on the market. No clearance under this code names a Chinese applicant. A registration is not a clearance: the plants above are set up to make it, and the 510(k) it is sold under is held by whoever files it, often the brand.

What Has Gone Wrong With It?

The FDA has recorded 20 recalls under this product code since 2010. None was by a company in China. The root causes the FDA records most often are Process change control (6), Process control (2) and Labeling Change Control (2).

A recall is a fact about one product and its maker, not a grade for every manufacturer of the type.
