Did you know2024
TCC Steel operates electroplating production lines that produce both tin-plated steel strip (electrolytic tinplate, ETP) for food and beverage cans and nickel-plated steel strip for EV battery cans — using the same cold-rolled steel base and the same electroplating bath technology, switching between tin and nickel electrolytes by changing the bath chemistry and anode material. TCC's food-can tinplate business and battery-can nickel plate business share electroplating production capacity that can be reallocated between tin and nickel plating based on demand. A surge in EV battery can demand (e.g., from rapid EV adoption in Korea/Japan) can pull TCC's electroplating capacity away from food can tinplate production. The food packaging supply chain (canned soup, vegetables, pet food) and the EV battery supply chain compete for the same electroplating production lines and the same cold-rolled steel substrate at Korean specialty steel producers like TCC.
TCC Steel Co., Ltd. ↗Concentration2024
The global supply of nickel-plated steel strip for cylindrical lithium-ion battery cans is controlled by approximately five producers: TCC Steel and POSCO (Korea), Toyo Kohan and JFE Steel (Japan), and one or two Chinese producers. This small supplier base is a critical upstream constraint for the global cylindrical cell supply chain — Samsung SDI, LG Energy Solution, Panasonic, and Sony Energy Devices all require nickel-plated steel strip for 18650 and 21700 cylindrical cells used in EV battery packs, power tools, and consumer electronics. The US Section 232 steel tariffs and South Korea's US FTA exemption mean TCC Steel's nickel-plated strip faces different US market access than Chinese or Japanese producers — making Korean producers the default non-Chinese sourcing option for US battery manufacturers seeking tariff-exempt nickel-plated steel strip.
Financial Supervisory Service (DART), TCC Steel ↗Origin2024
TCC Steel Co., Ltd. is headquartered in Pohang, South Korea — the city dominated by POSCO's vast Pohang steelworks, the largest integrated steel complex in the world by single-site capacity. TCC Steel's business model depends directly on POSCO: it purchases cold-rolled steel coil from POSCO's Pohang works and processes it through precision electroplating lines to produce the tin-plated and nickel-plated steel strip sold to can manufacturers and battery producers. TCC Steel is a downstream beneficiary of POSCO's position as the anchor supplier of Pohang's industrial ecosystem — the geographic clustering of POSCO's steel production and TCC's electroplating operations minimizes raw material logistics costs and gives TCC daily access to freshly-rolled cold-rolled steel before it can oxidize and develop surface defects that would reject it for plating.
