CPSIA对金属镀层的铅限制也同涂层吗？

(1) Paint and other similar surface-coating materials means a fluid, semi-fluid, or other material, with or without a suspension of finely divided coloring matter, which changes to a solid film when a thin layer is applied to a metal, wood, stone, paper, leather, cloth, plastic, or other surface. This term does not include printing inks or those materials which actually become a part of the substrate, such as the pigment in a plastic article, or those materials which are actually bonded to the substrate, such as by electroplating or ceramic glazing.
油漆和其他类似表层材料是指含有或不含悬浮状态的被细分过的色素的液体、半-液体或其他的材料。当这些材料被作为薄层用于诸如金属、木材、石头、纸、皮革、布料，塑料或其他表面的时候，就变成固体的薄膜。这个界定不包括印刷墨水或者那些实际上已经变成基层的材料，例如塑料制品中的颜料，或者那些事实上与底层结合到一起的材料，例如通过电镀或上瓷器釉。

这个是 16 CFR 1303 对油漆和涂层的描述
而CPSC-CH-E1003-09是引用它的描述的
所以金属镀层不是CPSC-CH-E1003-09里说的涂层
