Technical process findings in tariff classification were upheld, and no interference with the lower view was warranted.

Classification of a product under Tariff Item 2505.90 depended on technical process findings already accepted by the adjudicating authority and Tribunal. In such disputes, the Tribunal's factual conclusions are ordinarily not disturbed unless material exists to support a different classification. No such material was shown here, so the appellate court declined interference and the classification adopted below remained undisturbed.
