This is an appeal from the September 11, 1990, judgment of the Court of International Trade which held that the International Trade Commission has the authority to determine which domestic products are “like products”, even if the determination differs from the like product description in the petition to the Commission, and that the determination was supported by substantial evidence. Torrington Co. v. United States, 747 F.Supp. 744 (Ct.Int’l Trade 1990). We affirm.

BACKGROUND

On March 31, 1988, the Torrington Company filed an antidumping and countervailing duty petition with the International Trade Commission on behalf of the domestic industry that produces antifriction bearings. The petition described one type of product, antifriction bearings.

Based on the petition, the Commission initiated an investigation. In May 1989, the Commission issued final injury determinations for six types of products, viz., (1) ball bearings, (2) spherical roller bearings, (3) cylindrical roller bearings, (4) needle roller bearings, (5) plain bearings, and (6) slewing rings. Subsequently, the Commission rendered affirmative injury determinations only for types 1, 3, and 5.

Torrington appealed the Commission’s determination that there were six “like products” to the Court of International Trade. The court did not review the injury determinations, nor do we. It held that the Commission did not err in determining that there were six like products as opposed to the one product alleged in Torrington’s petition, and that this determination was supported by substantial evidence. This appeal followed.

DISCUSSION

The principal issues here are (1) whether the Commission has the discretionary authority to determine the number of like products in an antidumping and countervailing duty investigation, and (2) whether the Commission’s determination that there were six like products was supported by substantial evidence. The first issue is a legal one which we review de novo, Matsushita Elec. Indus. Co. v. United States, 929 F.2d 1577, 1578 (Fed.Cir.1991); in the second, we review the evidence of record to determine whether substantial evidence supports the Commission’s determination, American Permac, Inc. v. United States, 831 F.2d 269, 273, 6 Fed.Cir. (T) 6, 10-11 (1987), cert. dismissed, 485 U.S. 901, 108 S.Ct. 1067, 99 L.Ed.2d 229 (1988).

Appellant argues that the Commission’s determination that there were six like products was in error because it relied upon an erroneous determination of the Department of Commerce that there were five classes of bearings, that the Commission abused its discretion, and that its determination was unsupported by substantial evidence.

Because the trial court performed a thorough and correct analysis of the facts and arguments raised, we affirm its decision and adopt its opinion as our own. Moreover, we note that the Commission is charged with administering the involved sections of the antidumping and countervailing duty laws. We will not disturb its interpretation unless it is unreasonable, and we conclude that it is not. See Chevron U.S.A. Inc. v. Natural Resources Defense Council, Inc., 467 U.S. 837, 843-44, 104 S.Ct. 2778, 2782, 81 L.Ed.2d 694 (1984). We have considered all of appellant’s arguments and find no reason to reverse the Court of International Trade.

CONCLUSION

The International Trade Commission has the discretionary authority to define the like products that are the subject of an antidumping and countervailing duty investigation. Its determination was supported by substantial evidence. The judgment of the court is therefore

AFFIRMED.
