Galvanized steel plate for export need to meet the mandatory certifications of multiple countries. The basic international certifications include ISO 9001 quality management system (covering 98% of export enterprises) and ISO 14001 environmental certification. The audit cycle is usually 3 to 6 months, and the certification fee accounts for about 1.5% to 3% of the value of the goods. According to the data from the World Customs Organization in 2023, the return rate of galvanized sheets without the CE marking exported to Europe is as high as 18%, while the customs clearance speed of products that meet the EN 10346:2015 standard (zinc coating thickness ≥20μm) has increased by 50%. The case of POSCO of South Korea in 2022 shows that after obtaining the ASTM A653 certification of the American standard, the annual growth rate of its market share in North America reached 12%, and the premium space of a single order reached 8%.
There are differentiated barriers to regional market access. The North American market requires UL certification (with a fire resistance test temperature that can withstand 538°C for 30 minutes) and FM certification (wind pressure resistance strength ≥2.5kPa). The average test cost is $15,000, but after passing, tariffs can be reduced by 5% to 10%. In Southeast Asian countries, SM mark certification is mandatory. For instance, the TISI standard in Thailand requires a salt spray test life of over 500 hours and a coating weight deviation of no more than ±10g/m². According to a McKinsey Supply Chain report, the mutual recognition policy among RCEP member countries in 2024 will reduce certification costs by 30%, and the customs clearance time in the Vietnamese market will be shortened from 15 days to 3 days.
Environmental compliance certification has become a new focus. The EU CBAM regulation requires the provision of a carbon footprint certificate (Scope 3 emission data). Starting from 2026, a carbon tax of €100 per ton will be imposed on products that fail to meet the standards, equivalent to a 25% increase in costs. Leading enterprises such as ArcelorMittal have passed the EPD certification (Life Cycle assessment covering 98% of the process from iron ore to finished products), and their carbon emission intensity is controlled at 1.8tCO₂ per ton of plate. Green steel certification (such as UL ECV 2805) can achieve a 7% product premium. Data from Baowu Group in 2023 shows that export orders with this certification increased by 40%.
Special application fields require specialized certification. Marine engineering galvanized sheets must pass NORSOK M-501 (salt spray corrosion resistance > 25 years) and DNV GL certifications, and the zinc-aluminum alloy coating must meet the ISO 14713 standard (corrosion rate < 1μm/ year). Food contact grade galvanized sheets require FDA 21 CFR 175.300 certification, with heavy metal leaching limits of lead ≤0.01mg/L and cadmium ≤0.005mg/L. Referring to the case of the seawater desalination project in Jubeil, Saudi Arabia, suppliers without the NACE MR0175 certification were directly excluded from the bidding, resulting in a loss of contract amount exceeding $80 million.
Origin and safety guarantee certification are indispensable. The FORM E certificate enables a 60% reduction in ASEAN tariffs, while the China Customs ECFA certificate of Origin reduces tariffs on exports to Taiwan by 8%. The anti-terrorism certification C-TPAT shortens the US customs inspection rate to 5% and reduces the inspection time by 70%. After the Suez Canal blockage incident in 2021, the pass rate of SMETA supply chain ethics audits increased by 65%, and the probability of logistics delays for enterprises that failed to pass increased by 40%. Intelligent authentication systems are becoming increasingly popular (such as blockchain verification platforms), and it is expected that by 2027, the risk of authentication fraud can be reduced by 90%, and compliance costs can be further lowered by 25%.
