Scope of Orders
The products covered by these orders are certain stainless steel sheet and strip in coils. Stainless steel is an alloy steel containing, by weight, 1.2 percent or less of carbon and 10.5 percent or more of chromium, with or without other elements. The subject sheet and strip is a flat-rolled product in coils that is greater than 9.5 mm in width and less than 4.75 mm in thickness, and that is annealed or otherwise heat treated and pickled or otherwise descaled. The subject sheet and strip may also be further processed (e.g., cold-rolled, polished, aluminized, coated, etc.) provided that it maintains the specific dimensions of sheet and strip following such processing.

Although the HTSUS subheadings are provided for convenience and customs purposes, the Department's written description of the merchandise covered by these orders is dispositive.
Excluded from the scope of these orders are the following: (1) sheet and strip that is not annealed or otherwise heat treated and pickled or otherwise descaled; (2) sheet and strip that is cut to length; (3) plate (i.e., flat-rolled stainless steel products of a thickness of 4.75 mm or more); (4) flat wire (i.e., cold-rolled sections, with a prepared edge, rectangular in shape, of a width of not more than 9.5 mm); and (5) razor blade steel.

See Chapter 72 of the HTSUS, ``Additional U.S. Note'' 1(d).
In response to comments by interested parties the Department has determined that certain specialty stainless steel products are also excluded from the scope of these orders. These excluded products are described below:
Flapper valve steel is defined as stainless steel strip in coils containing, by weight, between 0.37 and 0.43 percent carbon, between 1.15 and 1.35 percent molybdenum, and between 0.20 and 0.80 percent manganese. This steel also contains, by weight, phosphorus of 0.025 percent or less, silicon of between 0.20 and 0.50 percent, and sulfur of 0.020 percent or less. The product is manufactured by means of vacuum arc remelting, with inclusion controls for sulphide of no more than 0.04 percent and for oxide of no more than 0.05 percent. Flapper valve steel has a tensile strength of between 210 and 300 ksi, yield strength of between 170 and 270 ksi, plus or minus 8 ksi, and a hardness (Hv) of between 460 and 590. Flapper valve steel is most commonly used to produce specialty flapper valves in compressors.

Suspension foil is described as 302/304 grade or 202 grade stainless steel of a thickness between 14 and 127 microns, with a thickness tolerance of plus-or-minus 2.01 microns, and surface glossiness of 200 to 700 percent Gs. Suspension foil must be supplied in coil widths of not more than 407 mm and with a mass of 225 kg or less. Roll marks may only be visible on one side, with no scratches of measurable depth. The material must exhibit
