Steel bars from Germany will be forged in the United States by the importer into crankshafts, which obliterates any mark. Must the bars be marked?
19 CFR 134.32(g) excepts articles to be processed in the United States by the importer, otherwise than to conceal origin, in a way that would necessarily obliterate, destroy or permanently conceal the mark. 134.36 limits this where a reasonable method of marking would survive. Forging bars into crankshafts also substantially transforms them, making the forger the ultimate purchaser (134.1(d)(1), 134.35(a)). Source: 19 CFR 134.32(g), 134.35, 134.36 (eCFR, as at 7 Oct 2026).
