Korea green aluminum means recycled content and remelting, because Korea operates no primary smelter. The primary metal inside a Korean coil carries a foreign smelter’s emissions, and what a Korean mill controls is its scrap input, its melt, and the quality of its own emissions data. For a European buyer, that data decides the carbon cost of the entry.
The producer landscape sits in the reference guide to Korea’s aluminum industry. This piece covers the low carbon decision: Korean scrap supply, what producers can evidence on embodied carbon, what the EU’s Carbon Border Adjustment Mechanism does with that evidence, and how Korea’s emissions trading scheme touches the sector.
Data current as of September 2026.
What Does Green Aluminum Mean When Korea Smelts No Metal?
It means two levers, and only two. A Korean mill can raise the share of scrap in its melt, and it can buy lower carbon primary metal from a smelter abroad. Korea has no bauxite reserves and no primary smelting capacity, appearing nowhere in the smelter capacity table of the U.S. Geological Survey’s Mineral Commodity Summaries 2026, so the electrolysis emissions that dominate aluminum’s footprint arrive as a purchased input.
Both levers are visible in practice. Novelis reports 63 percent average recycled content group-wide in fiscal 2025, a target of 75 percent by 2030, and a fall in emissions intensity from 4.0 to 3.6 tonnes of CO2e per tonne of flat rolled product shipped (Novelis 2025 Sustainability Report). Those are group numbers. Novelis publishes no recycled content figure for Yeongju or Ulsan specifically, so 63 percent is not a figure to carry into a Korean quotation. The same report names Press Metal as a strategic metal supplier to Novelis in Korea and ties that relationship to low carbon primary aluminum.
The pull comes from customers and foreign regulation more than from Korean law. Korea’s recycled raw material obligation under the Act on the Promotion of Saving and Recycling of Resources runs to plastic: Article 33-3 sets a required ratio for manufacturers, and neither that Act nor the Act on the Promotion of Transition to a Circular Economy and Society sets one for aluminum (Korean Law Information Center statute text, 2026). A Korean mill lifting recycled content is answering an export customer.
Where Does Korea’s Scrap Supply Come From?
Mostly from abroad, and in volume. Korea imported 928,355 tonnes of aluminum waste and scrap under HS 7602 in 2025, worth 1.89 billion USD, against exports of 75,502 tonnes worth 148 million USD (UN Comtrade, reporter Korea, 2026). In 2024 imports ran at 939,789 tonnes, with the United States supplying 236,753 tonnes of that.
Read those numbers as a constraint on your order. Korean recycled content rests on imported feedstock bought in competition with Southeast Asian and Chinese furnaces. When scrap tightens, the mill pays up or dilutes with primary metal, and your embodied carbon figure moves with it. Ask for the contract form that holds: a guaranteed minimum scrap ratio per lot rather than an annual average, the melt mix basis in writing, and a named party bearing the CBAM cost if a lot falls below the ratio.
Domestic capacity is being built against that constraint. Novelis commissioned a recycling centre at Ulsan in the fourth quarter of fiscal 2025 with an annual capacity of 100,000 tonnes, expected to raise regional recycling capacity by more than 20 percent and widen the scrap types it accepts (Novelis 2025 Sustainability Report). That widening matters more than the tonnage, because sorted alloy scrap, painted stock and mixed post-consumer material carry different yields.
Korea controls that trade, and the control turns on cleanliness. Under the environment ministry notice listing wastes subject to the Act on the Transboundary Movement of Wastes, latest amendment 2026-151, effective 23 June 2026, aluminium scrap sits on Schedule 1 as Basel Annex IX entry B1010, so it is green listed and needs no import permit under Article 10 (Korean Law Information Center, 2026). Schedule 2 puts waste metals on the Article 18-2 import declaration list, with note 3 excluding scrap iron and non-ferrous metal that is exempt from business waste generator reporting, and then only where the material carries no waste oil contamination and no foreign matter. Note 5 bans outright anything listed on the separate notice restricting imports to protect domestic recycling. Contamination spec therefore decides import eligibility in Korea before it decides yield, so write it into the specification and the inspection terms.
For foreign scrap merchants, that is the commercial opening in the Korean chain, and Inquivix Technologies covers the trade mechanics in its overview of the aluminum scrap supply chain.
What Can Korean Producers Actually Evidence?
More on certification than a buyer expects, less on product level carbon data.
The strongest evidence in Korea is the Aluminium Stewardship Initiative. Novelis Korea Limited holds ASI certificate 140 against the Performance Standard V3.1 at full certification, issued 26 June 2024 and valid to 25 June 2027, scoped to aluminium coil and sheet including recycling and remelting at the Yeongju plant (ASI audit report for certificate 140). ASI separately recertified it against the Chain of Custody Standard V2. Ulsan Aluminum, the Novelis and Kobe Steel joint venture, took the Performance Standard in November 2021, with Korea-wide certification announced in June 2022 (Novelis, 2022). Chain of Custody is the standard that carries a recycled content claim through a sale, so ask which one a supplier holds. Inquivix Technologies covers ASI as a working certification in its guide to sustainable aluminum extrusion.
Korean producers publish more sustainability reporting than a first search suggests. Lotte lists a Lotte Aluminium sustainability report on the Lotte group ESG portal, most recently for 2024, and Choil Aluminum and Dongwon Systems both run sustainability sections on their corporate sites.
Korea also certifies product carbon itself, and that register is the one domestic surface that holds a number. KEITI, under the environment ministry, runs environmental product declaration and low carbon product certification at ecosq.or.kr, with carbon footprint among the disclosed categories. As of 31 December 2025 the register covered 653 companies and 3,189 products, 1,527 of them low carbon certified, and carried no aluminium coil, sheet, plate or foil; its only aluminium entries are two Iljin Electric rod products declared at 20.0 and 20.2 kg of CO2e per kg (Ministry of Climate, Energy and Environment, February 2026). Those totals are cradle to gate and sit almost entirely in the pre-manufacturing stage, so they answer a different question from a CBAM declaration, which counts direct emissions at the installation.
What is scarce is the number a carbon buyer needs: verified recycled content and product carbon footprint per alloy and per plant for a specific coil. Put that in the request for quotation.
What Does CBAM Do With a Korean Coil?
It prices the embedded emissions you declare, using the producer’s verified data where you hold it and a published country default where you do not. Entry mechanics for a Korean shipment, including the definitive regime that began on 1 January 2026 and the certificate price it runs on, sit in the guide to importing aluminum from Korea.
Be clear about which part of that number the mill owns. Its own data covers its melt and its process emissions, which it can measure and have verified. The upstream emissions of the primary units it bought travel with the ingot, so the mill can only relay what its smelter supplier discloses. That line decides whether a data gap is the mill’s to close or unfixable inside your contract, and it is worth establishing before you escalate a refusal.
The default values are why mill data has a price. In the Commission’s default values file for the definitive period, published 10 August 2026 with the binding values in Commission Implementing Regulation (EU) 2026/1740 correcting Commission Implementing Regulation (EU) 2025/2621, the Korean figures are 0.360 tonnes of CO2e per tonne for unwrought aluminium of CN 7601, 1.500 for profiles of CN 7604, and 1.950 for plates, sheets and strip of CN 7606 and foil of CN 7607, all direct emissions, with indirect listed as not applicable.
That spread is the negotiation, and it prices out cleanly. At the 1.950 default for CN 7606 sheet and a certificate price of EUR 75.36 for the first quarter of 2026, a tonne of Korean coil carries about EUR 147 in certificates before any mill data exists, and each tonne of CO2e that verified data removes is worth EUR 75.36 per tonne of coil. Rolled product defaults at more than five times the unwrought figure, so missing installation data costs most on sheet and foil, including the grades covered in the guide to Korean aluminum suppliers of sheet, plate and coil.
The commercial market draws its line somewhere else. Fastmarkets defines low carbon aluminium as primary metal at a maximum of 4 tonnes of CO2e per tonne under Scope 1 and 2, has assessed a CIF Japan and South Korea differential since 1 March 2024, and reports Asia’s low carbon differentials as the highest globally (Fastmarkets, 2026). That definition excludes scrap content, for want of an accepted global definition of low carbon scrap. The two systems can therefore disagree about the same coil: CBAM treats scrap as zero embedded emissions, so a Korean secondary melt can file a low CBAM figure and still fail the commercial low carbon test.
Scrap is why the gap can be so large. The Commission’s aluminium sector guidance states that scrap, pre-consumer or post-consumer, is treated as a raw material with zero embedded emissions (Guidance No. 5e, sector specific guidance document on aluminium, European Commission, August 2026). Aluminium waste and scrap of CN 7602 also sits outside the covered goods. A Korean secondary melt therefore reports a genuinely low direct figure, provided the producer documents it.
Two sector parameters carry that documentation, and both come from the producer. The Commission’s guidance requires the annual report to state the tonnes of scrap used per tonne of the good and the pre-consumer percentage of that scrap, for unwrought aluminium and aluminium products alike, plus the total percentage of alloying elements above 1 percent. Actual values need verification by an accredited verifier under Commission Delegated Regulation (EU) 2025/2551. A supplier spreadsheet with no verifier behind it does not replace a default value.
Does Korea’s Emissions Trading Scheme Reduce Your CBAM Bill?
Barely, and the reason is structural. CBAM allows a deduction where a carbon price has already been paid during the production of the imported goods (European Commission, CBAM definitive regime, 2026). Korea prices carbon, but it hands the relevant sectors their allowances free.
Korea approved the Phase 4 allocation plan for the Korea Emissions Trading Scheme on 11 November 2025, covering 2026 to 2030 with a cap of 2,537.3 million tonnes of CO2e including reserves. Sectors judged at risk of carbon leakage, named as steel, non-ferrous metals, petrochemicals, cement and semiconductors, keep 100 percent free allocation, while other non-power sectors face a 15 percent auction rate. Benchmark based allocation extends to non-ferrous metals for the first time in this phase. Prices are low by European standards in any case: the 2025 average auction price was 9,956 KRW and the average secondary market price 9,393 KRW per tonne (International Carbon Action Partnership, 2026).
Two consequences follow. A Korean producer inside the scheme pays little or nothing per tonne on its free allocation, so the carbon price paid deduction is small. Coverage is also partial: the scheme takes in companies emitting 125,000 tonnes of CO2e or more with at least one facility above 25,000 tonnes, leaving many mid-sized rollers and foil producers outside it with no regulated verified inventory. Ask whether the plant is a covered entity before assuming its numbers passed a compliance verification.
Plan for what a Korean mill will not have. Outside the Novelis cluster, an EU accredited verifier’s statement is not standard equipment for a Korean rolling mill, and the coverage threshold above leaves many mid-sized rollers with no verified inventory to build from, so a first request often starts a process rather than retrieving a document. Verification is scheduled and paid for before the goods ship. If the data does not arrive, the fallback is to declare on the country default and pay the certificates at the per tonne figures above. Price that outcome into the contract at signature rather than meeting it at the first declaration.
What Should You Put in the Purchase Order?
Write the carbon requirement into commercial terms alongside alloy and temper, so it carries a price.
- Installation level emissions data per product and CN code, in the Commission’s communication format, with the verifier named and accredited.
- Tonnes of scrap per tonne of finished product and the pre-consumer share of that scrap, since both are reportable parameters.
- ASI certificate numbers, standard version, scope and expiry, plus Chain of Custody status where a recycled content claim travels with the metal.
- Whether the plant is a K-ETS covered entity, and the plant level emissions figure it reports.
- A duty to reissue the data annually, since certificates are surrendered annually and melt mixes change.
- For battery and automotive programs, the same data from the plant that will run the order, which is often not the plant that was audited, as the qualification tracks in the guide to aluminum in Korea’s EV and battery supply chain show.
One lever sits on the Korean side of the table. The government runs joint ministry CBAM briefings for exporters, the eleventh on 21 April 2026 in Seoul with on-site consulting and a help desk (Ministry of Trade, Industry and Energy, 2026), and the Ministry of SMEs and Startups funds a CBAM infrastructure program covering measurement equipment and MRV build-out at up to 42 million KRW per company and third party verification at up to 3.5 million KRW, whose third 2026 round is open to 15 September 2026 (Ministry of SMEs and Startups notice 2026-522). Aluminium CN codes sit inside its covered goods list. A mid-sized mill that says it has no installation data may be eligible for state funding to produce it, which turns a refusal into a schedule.
Frequently Asked Questions
Is Korean aluminum low carbon?
It depends on the plant and the melt more than on the country. Korea smelts no primary metal, so a Korean product’s footprint turns on its scrap share and which foreign smelter supplied the primary units. Novelis reported 63 percent average recycled content group-wide in fiscal 2025, not a Yeongju or Ulsan figure. Korea’s own certified carbon register, KEITI’s environmental product declaration list, held no aluminium coil, sheet or foil entry at 31 December 2025.
Does recycled content remove the CBAM cost of Korean aluminum?
It reduces it substantially. The Commission’s aluminium guidance treats scrap, pre-consumer or post-consumer, as a raw material with zero embedded emissions, so a high scrap melt reports low direct emissions. That reduction reaches your declaration only if the producer supplies verified installation data with the tonnes of scrap per tonne and the pre-consumer share. Otherwise the country default applies.
What CBAM default value applies to Korean aluminum?
For Korea, the published definitive period defaults are 0.360 tonnes of CO2e per tonne for unwrought aluminium of CN 7601, 1.500 for profiles of CN 7604, and 1.950 for sheet and strip of CN 7606 and foil of CN 7607, all direct emissions, with indirect not applicable. Binding values sit in Commission Implementing Regulation (EU) 2026/1740, correcting Commission Implementing Regulation (EU) 2025/2621.
How do I verify a Korean mill’s recycled content claim?
Start with ASI Chain of Custody, which is the standard that carries a recycled content claim through a transaction, and check the certificate number, scope and expiry rather than a logo. Then require the CBAM sector parameters in the purchase order and an accredited verifier’s statement under Commission Delegated Regulation (EU) 2025/2551. A mill test certificate alone says nothing about carbon.
Getting the Carbon Evidence Before the Order
Korean aluminum can land in Europe at a low declared carbon figure, and the gap between that and a default value is a document the mill either has or does not. Settle the emissions data, scrap parameters and certification scope at quotation, while commercial terms are still open.
Aluminum coil, sheet, and foil supply in specific alloys, including recycled and low carbon grades, is handled by Inquivix Technologies. To discuss a Korean low carbon aluminum requirement or a CBAM data gap with a supplier, write to joon@joonklee.com or use the contact page.
