【SMM Steel】EU cargo delays rise after CBAM tax starts in 2026

【SMM Steel】Since CBAM entered its tax phase on Jan 1, 2026, goods are held at EU ports due to clearance issues. Importers must be registered CBAM declarants. Common problems: missing declarant status, wrong CBAM codes, no emission data. Non-compliant goods are blocked. CBAM is now a trade access condition. Firms must register, use correct codes, track the 50-ton annual exemption, and set up carbon reporting. While importers are legally responsible, exporters face shipment delays and lost trust. CBAM compliance is key for steel, aluminum, and fastener exports to the EU.
