1. Anti-Dumping Duties (ADD) and Tariffs
ADD investigations impose 20–50% tariffs on imported ABS-grade steels, forcing buyers to seek costlier alternatives.
Case Study: The U.S. Department of Commerce's 232 tariffs (2018) raised Chinese AH36 plate prices by 30%, pushing shipbuilders to source from pricier EU mills.
ABS Compliance Costs: Suppliers passing ADD costs to buyers add $150–300/ton to contracts.
Workarounds: Some importers use third-country processing to bypass duties, but ABS requires mill-specific certification, limiting flexibility.
Tariffs also distort free trade agreements (FTAs)-e.g., South Korean POSCO's U.S. shipments now face 25% duties despite KORUS FTA provisions.
2. Supply Chain Fragmentation
Export bans and sanctions reduce available ABS-approved suppliers, creating regional shortages.
Price Volatility: European ABS DH36 prices surged 40% in 2022 due to lost Russian supply (12% of global output).
Lead Time Delays: Sourcing from alternative mills extends delivery from 8 to 20 weeks, increasing project costs.
ABS Audit Bottlenecks: New suppliers require ABS mill approval, a 6–12-month process, delaying procurement.
Shipyards now over-order to hedge against shortages, tying up capital in inventory.
3. Raw Material Cost Inflation
Trade barriers on inputs indirectly raise ABS steel prices:
China's Export Restrictions: 2023 graphite export controls increased electric arc furnace (EAF) production costs by 15%.
Australia-China Coal Tariffs: Coking coal prices spiked 60% in 2021, raising blast furnace steelmaking costs.
ABS Traceability Rules: Mills must document conflict-free minerals, adding compliance overheads.
High raw material costs disproportionately impact smaller ABS-certified mills, reducing competition.
4. Logistics and Shipping Disruptions
Geopolitical conflicts reroute shipments, raising freight costs:
Container Rates: Shanghai-Rotterdam costs tripled in 2023, adding $50–120/ton to steel deliveries.
ABS "Just-in-Time" Challenges: Delays force shipbuilders to airfreight critical plates at 10x sea costs.
Insurance Surcharges: War-risk premiums for Black Sea shipments now exceed 1% of cargo value.
ABS requires batch-specific documentation, complicating last-minute supplier switches.
5. Localization and Subsidy Wars
Domestic content mandates favor local ABS mills but raise costs:
Price Premiums: U.S.-made AH36 costs 25% more than imported equivalents due to labor/energy costs.
Subsidy Dependence: EU mills rely on state aid to compete, creating market distortions.
ABS Certification Delays: New mills take 2+ years to gain ABS approval.
