Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If alloy steel orifice types
Material alloying separates headings within flanges.
If including integral flow instruments
Instrument-integrated flanges become Chapter 90 articles.
If bulk industrial scrap/seconds
Imperfect forgings may classify as other steel fabrications.
