CBAM (EU) + Thailand Carbon Tax Compliance

CBAM (EU) + Thailand Carbon Tax Compliance · § CrossBorder
Quick Answer
CBAM registration at EU CBAM Registry via EU importer (indirect representative) · quarterly report of embedded emissions per default value or verified actual · from 2026 buy CBAM certificate at EU ETS weekly avg (~€85/tCO₂e) · Thai credit deductible 1:1.
Timeline: CBAM report quarterly (30 days after quarter-end) · non-compliance fine €10–50/tCO₂e unreported · Thai carbon tax filed annually.
Official fee: CBAM certificate = EU ETS spot × embedded emissions (cement 0.83 tCO₂e/ton × €85 = €70/ton · steel billet 1.9 tCO₂e/ton × €85 = €162/ton) · EU-accredited verification €8,000–25,000 · Thai carbon tax est. THB 200/tCO₂e.
Legal Basis
EU Regulation 2023/956 (CBAM) — transitional 1 Oct 2023 – 31 Dec 2025 (report only) · definitive 1 Jan 2026 (buy CBAM certificates) · covers steel, aluminium, cement, fertiliser, electricity, hydrogen · Thai Climate Change Act (draft) — expected Q1/2026 · ETS + carbon tax THB 200/tCO₂e from 2026 · US CCA (pending).
Who Needs This
Thai exporters of steel/aluminium/cement/fertiliser/hydrogen to EU · smelters · cement plants on SET (SCG, TPI) · downstream users of carbon-intensive EU inputs · SME suppliers of EU importers.
Required Documents
- Product carbon footprint (PCF) per ISO 14067 or EU CBAM methodology
- Energy consumption + emission factor per production line
- Monthly production volume per CN code (8-digit)
- Invoice + BL to EU + EU importer EORI number
- Carbon price paid in Thailand (retired T-VERs) — 1:1 deductible.
Common Pitfalls
- Using EU default values (30–80% higher than actual) = overpayment · verified actual pays back < 18 mo.
- Downstream (cars, appliances) not CBAM now but scope-in 2030 · prepare early.
- Carbon leakage: shifting from EU→non-EU works short-term but damages long-term relationships.
- Thailand has no live ETS yet = Thai credits not fully deductible from CBAM · lobby for recognition.
- Thai carbon tax + CBAM = double burden without planning.
Typical Use-cases
- SCG cement to Netherlands · 20,000 t/mo · CBAM cost €1.4M/mo from 2026
- Sahaviriya steel billet to EU · verified PCF cuts CBAM 40%
- Aluminium wheel OEM to Germany · Scope 3 for BMW ESG report
- Thai Central Chemical fertiliser to Poland · CBAM report Q1/2026.
FAQ
- Not exporting to EU — should I worry?
- Indirectly: (1) EU exporter suppliers asked for PCF (2) US CCA looming (3) UK CBAM 2027 · Australia studying · prepare PCF early.
- Can T-VERs offset CBAM?
- Not yet — EU doesn't recognize T-VER · needs explicit Thai ETS or carbon tax paid · TGO negotiating MRA.
- Who verifies PCF?
- EU-accredited verifier (DNV, TÜV SÜD, Bureau Veritas) · €8k–25k · valid 1–3 yrs.
- When to start prep?
- Now — Q1/2026 mandatory payment · PCF takes 3–6 mo · verification 2 mo · registration 1 mo.

Frequently asked questions
- Can a foreigner own 100% of a Thai company?
- Generally no for activities listed in the Foreign Business Act, where majority foreign ownership requires a Foreign Business Licence, a BOI promotion, or treaty rights such as the US–Thailand Treaty of Amity. Manufacturing and certain export activities are largely open, and BOI-promoted activities can permit full foreign ownership together with land-holding and visa privileges, so the right structure depends on the specific activity.
- What is the minimum registered capital for a Thai company?
- There is no general statutory minimum for a Thai-majority company, but practical thresholds apply: THB 2 million of paid-up registered capital per foreign work permit, or THB 1 million if the foreigner is married to a Thai national, and THB 3 million per foreign shareholder for a Foreign Business Licence. Capital should therefore be planned around the visa and work-permit outcome you need, not the incorporation minimum.
- How long does company registration take?
- Registration at the Department of Business Development can be completed within one to three working days once the name reservation, shareholder documents and company objectives are ready, and the VAT registration and social security registration follow afterwards. The realistic end-to-end timeline including bank account opening is two to six weeks, with the bank account usually being the slowest step for foreign directors.
- What ongoing accounting obligations does a Thai company have?
- Every Thai company must keep statutory accounts, file monthly withholding tax (PND 1, 3, 53) and VAT (PP 30) returns by the middle of the following month, file the half-year corporate income tax return (PND 51) and the annual return (PND 50), and have its financial statements audited by a Thai CPA and filed with the DBD each year. Dormant companies are not exempt — nil returns and an audited statement are still required.
