品目8479条文注解二 （五）描述了可以作为金属处理机器归类的货品种类。例举的金属处理的方式包括表面清洗擦亮，酸洗， 镀锡， 和除砂。你递交的材料中描述的生产过程于前面引用的条文注解中设定的范例不相似，所以这个货品不能归类在8479.81.0000，美国税则下。

Even supposing either proposed classification applied, the merchandise would be classified in accordance with Note 2 to Chapter 84. Said note reads, in pertinent part,

即使假设任何一个建议的归类品目是适用的，这个物品的归类还应该根据84章章注二。所提到的章注的相关内容是

Subject to the operation of Note 3 to Section XVI and subject to Note 9 to this chapter, a machine or appliance which answers to a description in one or more of the headings 8401 to 8424, or heading 8486 and at the same time to a description in one or more of the headings 8425 to 8480 is to be classified under the appropriate heading of the former group or under heading 8486, as the case may be, and not the latter group.

除第十六类注释三及本章注释九另有规定以外，如果某种机器或器具既符合品目84.01至84.24中一个或几个品目的规定，或符合品目84.86的规定，又符合品目84.25至84.80中一个或几个品目的规定，则应酌情归入品目84.01至84.24中的相应品目或品目84.86，而不归入品目84.25至84.80中的有关品目

As the merchandise is classifiable in a heading of the former group, classification in either subheading 8454.30.0090 or subheading 8479.81.0000 would be precluded.
