Appendix I--Scope of the AD and CVD Orders on 1-Hydroxyethylidene-1, 1-
Diphosphonic Acid From China (A-570-045 and C-570-046)

    The merchandise covered by these orders includes all grades of 
aqueous acidic (non-neutralized) concentrations of HEDP, also 
referred to as hydroxyethylidenendiphosphonic acid, 
hydroxyethanediphosphonic acid, acetodiphosphonic acid, and 
etidronic acid. The Chemical Abstract Service (CAS) registry number 
for HEDP is 2809-21-4.
    The merchandise subject to these orders is currently classified 
in the Harmonized Tariff Schedule of the United States (HTSUS) at 
subheading 2931.90.9043. It may also enter under HTSUS subheadings 
281.19.6090 and 2931.90.9041. While HTSUS subheadings and the CAS 
registry number are provided for convenience and customs purposes 
only, the written description of the scopes of these orders is 
dispositive.

Appendix II--Scope of the AD Order on Cold-Rolled Steel Flat Products 
From Japan (A-588-873)

    The products covered by this order are certain cold-rolled 
(cold-reduced), flat-rolled steel products, whether or not annealed, 
painted, varnished, or coated with plastics or other non-metallic 
substances. The products covered do not include those that are clad, 
plated, or coated with metal. The products covered include coils 
that have a width or other lateral measurement (width) of 12.7 mm or 
greater, regardless of form of coil (e.g., in successively 
superimposed layers, spirally oscillating, etc.). The products 
covered also

[[Page 13954]]

include products not in coils (e.g., in straight lengths) of a 
thickness less than 4.75 mm and a width that is 12.7 mm or greater 
and that measures at least 10 times the thickness. The products 
covered also include products not in coils (e.g., in straight 
lengths) of a thickness of 4.75 mm or more and a width exceeding 150 
mm and measuring at least twice the thickness. The products 
described above may be rectangular, square, circular, or other shape 
and include products of either rectangular or non-rectangular cross-
section where such cross-section is achieved subsequent to the 
rolling process, i.e., products which have been ``worked after 
rolling'' (e.g., products which have been beveled or rounded at the 
edges). For purposes of the width and thickness requirements 
referenced above:
    (1) Where the nominal and actual measurements vary, a product is 
within the scope if application of either the nominal or actual 
measurement would place it within the scope based on the definitions 
set forth above, and
    (2) where the width and thickness vary for a specific product 
(e.g., the thickness of certain products with non-rectangular cross-
section, the width of certain products with non-rectangular shape, 
etc.), the measurement at its greatest width or thickness applies.
    Steel products included in the scope of this order are products 
in which: (1) Iron predominates, by weight, over each of the other 
contained elements; (2) the carbon content is 2 percent or less, by 
weight; and (3) none of the elements listed below exceeds the 
quantity, by weight, respectively indicated:

 2.50 percent of manganese, or
 3.30 percent of silicon, or
 1.50 percent of copper, or
 1.50 percent of aluminum, or
 1.25 percent of chromium, or
 0.30 percent of cobalt, or
 0.40 percent of lead, or
 2.00 percent of nickel, or
 0.30 percent of tungsten (also called wolfram), or
 0.80 percent of molybdenum, or
 0.10 percent of niobium (also called columbium), or
 0.30 percent of vanadium, or
 0.30 percent of zirconium

Unless specifically excluded, products are included in this scope 
regardless of levels of boron and titanium.
    For example, specifically included in this scope are vacuum 
degassed, fully stabilized (commonly referred to as interstitial-
free (IF)) steels, high strength low alloy (HSLA) steels, motor 
lamination steels, Advanced High Strength Steels (AHSS), and Ultra 
High Strength Steels (UHSS). IF steels are recognized as low carbon 
steels with micro-alloying levels of elements such as titanium and/
or niobium added to stabilize carbon and nitrogen elements. HSLA 
steels are recognized as steels with micro-alloying levels of 
elements such as chromium, copper, niobium, titanium, vanadium, and 
molybdenum. Motor lamination steels contain micro-alloying levels of 
elements such as silicon and aluminum. AHSS and UHSS are considered 
high tensile strength and high elongation steels, although AHSS and 
UHSS are covered whether or not they are high tensile strength or 
high elongation steels.
    Subject merchandise includes cold-rolled steel that has been 
further processed in a third country, including but not limited to 
annealing, tempering, painting, varnishing, trimming, cutting, 
punching, and/or slitting, or any other processing that would not 
otherwise remove the merchandise from the scope of the order if 
performed in the country of manufacture of the cold-rolled steel.
    All products that meet the written physical description, and in 
which the chemistry quantities do not exceed any one of the noted 
element levels listed above, are within the scope of this order 
unless specifically excluded. The following products are outside of 
and/or specifically excluded from the scope of this order:

---------------------------------------------------------------------------

    \9\ See Grain-Oriented Electrical Steel from Germany, Japan, and 
Poland: Final Determinations of Sales at Less Than Fair Value and 
Certain Final Affirmative Determination of Critical Circumstances, 
79 FR 42501, 42503 (July 22, 2014) (Grain-Oriented Electrical Steel 
from Germany, Japan, and Poland). This determination defines grain-
oriented electrical steel as ``a flat-rolled alloy steel product 
containing by weight at least 0.6 percent but not more than 6 
percent of silicon, not more than 0.08 percent of carbon, not more 
than 1.0 percent of aluminum, and no other element in an amount that 
would give the steel the characteristics of another alloy steel, in 
coils or in straight lengths.''
---------------------------------------------------------------------------

     Non-Oriented Electrical Steels (NOES), as defined in 
the antidumping orders issued by the U.S. Department of Commerce in 
Non-Oriented Electrical Steel from the People's Republic of China, 
Germany, Japan, the Republic of Korea, Sweden, and Taiwan.\10\
---------------------------------------------------------------------------

    \10\ See Non-Oriented Electrical Steel from the People's 
Republic of China, Germany, Japan, the Republic of Korea, Sweden, 
and Taiwan: Antidumping Duty Orders, 79 FR 71741, 71741-71742 
(December 3, 2014) (Non-Oriented Electrical Steel from the People's 
Republic of China, Germany, Japan, the Republic of Korea, Sweden, 
and Taiwan). The orders define NOES as ``cold-rolled, flat-rolled, 
alloy steel products, whether or not in coils, regardless of width, 
having an actual thickness of 0.20 mm or more, in which the core 
loss is substantially equal in any direction of magnetization in the 
plane of the material. The term `substantially equal' means that the 
cross grain direction of core loss is no more than 1.5 times the 
straight grain direction (i.e., the rolling direction) of core loss. 
NOES has a magnetic permeability that does not exceed 1.65 Tesla 
when tested at a field of 800 A/m (equivalent to 10 Oersteds) along 
(i.e., parallel to) the rolling direction of the sheet (i.e., B800 
value). NOES contains by weight more than 1.00 percent of silicon 
but less than 3.5 percent of silicon, not more than 0.08 percent of 
carbon, and not more than 1.5 percent of aluminum. NOES has a 
surface oxide coating, to which an insulation coating may be
