Opinion
Tsoucalas, Judge:Plaintiff, GMN Georg Muller Nürnberg AG (“GMN”), moves pursuant to Rule 56.1 of the Rules of this Court for partial judgment on the agency record as to Count 13C of its complaint claiming that the Department of Commerce, International Trade Administration’s (“ITA” or “Commerce”) proposed assessment rate methodology for exporter’s sales price (“ESP”) sales is contrary to law and not supported by substantial evidence on the record.
The administrative determination under review is the ITA’s final results in Antifriction Bearings (Other Than Tapered Roller Bearings) and Parts Thereof From the Federal Republic of Germany; Final Results of Antidumping Duty Administrative Review {“Final Results”), 56 Fed. Reg. 31,692 (1991).
Background

Reg. 23,575 (1990). GMN participated in this review. Id.

On July 11, 1991, the ITA published its Final Results in this proceeding. Final Results, 56 Fed. Reg. at 31,692.
Discussion
In reviewing a final determination of Commerce, this Court must uphold that determination unless it is “unsupported by substantial evidence on the record, or otherwise not in accordance with law.” 19 U.S.C. § 1516a(b)(1)(B) (1988). Substantial evidence has been defined as being “more than a mere scintilla. It means such relevant evidence as a reasonable mind might accept as adequate to support a conclusion.” Universal Camera Corp. v. NLRB, 340 U.S. 474, 477 (1951) (quoting Consolidated Edison Co. v. NLRB, 305 U.S. 197, 229 (1938)). It is “not within the Court’s domain either to weigh the adequate quality or quantity of the evidence for sufficiency or to reject a finding on grounds of a differing interpretation of the record.” The Timken Co. v. United States, 12 CIT 955, 962, 699 F. Supp. 300, 306 (1988), aff’d, 894 F.2d 385 (Fed. Cir. 1990).
In this case, plaintiff contests Commerce’s method of calculating the antidumping duty assessment rate for ESP transactions. In its investigation, Commerce employed separate methodologies for exporter sales price and purchase price transactions in order to arrive at appropriate assessment rates.
For ESP sales, Commerce divided the total potential uncollected dumping duties (“PUDD”) by the total entered value of those reviewed sales for each importer. Because of the enormous volume of ESP transactions, Commerce sampled the transactions of each company with more than 2,000 such transactions. Final Results, 56 Fed. Reg. at 31,698-99. From this sample, a PUDD was derived for each company. Commerce stated that “[ajlthough this approach will result in the assessment of a dumping margin based, to some extent, on sales of merchandise imported outside the [period of review], it is the most accurate rate that can be calculated on the basis of the information on the record.” Id. at 31,694.
Plaintiff claims that the “better” way for Commerce to have acted would have been for it to calculate the assessment rates based on the ratio of total dumping duties owed to the total entered value of the subject merchandise during the period of review. Commerce, however, could not have followed this method for two reasons. First, Commerce was unaware of the size of the universe from which the sample was drawn. Second, Commerce did not have information about the total entered value of units entered during the review period. Thus, Commerce was forced to use sampling techniques and use the sales data they had.
*268It is well-established that Commerce is granted flexibility in selecting the appropriate methodology. ICC Indus., Inc. v. United States, 812 F.2d 694, 699 (Fed. Cir. 1987); Consumer Prod. Div., SCM Corp. v. Silver Reed America, Inc., 753 F.2d 1033, 1039 (Fed. Cir. 1985). As long as Commerce’s “decision is reasonable, then Commerce has acted within its authority even if another alternative is more reasonable.” See Koyo Seiko Co. v. United States, 16 CIT 366, 372, 796 F. Supp. 517, 523 (1992).
In this case Commerce’s methodology was a reasonable means of achieving the end result. Id. Therefore, Commerce’s actions were justified and in accordance with law.
