EU renewable energy: Chinese supplier Dajin now leading in offshore wind foundations

A Chinese manufacturer has become the top supplier of foundations for Europe's offshore wind farms, overtaking its main European rival. This surge highlights the EU's struggle to balance its green energy goals with economic security. Dajin Heavy Industrial's success is built on a significant cost advantage and vertical integration, a strategy that is now drawing regulatory scrutiny.

Dajin Heavy Industrial has overtaken Sif Holding as the leading supplier of offshore wind foundations to the European market. Measured by monopile sales value, Dajin's share rose from 18.5% in 2024 to 29.1% in the first half of 2025, while Sif's fell from 23.1% to 18.2%, according to Frost & Sullivan. Dajin's export revenue, the bulk of which derives from foundation deliveries to Europe, grew by 165% year-on-year in 2025 and by a further 20% in the first half of 2026.

Dajin maintains a cost advantage without compromising profit margins

Dajin's H1 2026 interim report discloses export deliveries of offshore structures approaching 120,000 metric tons, consisting mainly of monopiles shipped on delivered-at-place terms from its production base in Penglai, Shandong Province, to Europe. Set against export revenue of 2.68bn RMB, this implies roughly 2,820 EUR per metric ton, compared with approximately 3,535 EUR per metric ton for Sif.

Dajin therefore lands finished monopiles in Europe some 20% below Sif's price at the quay, and does so despite bearing the freight costs from Shandong, which Sif does not incur. The true price gap is more likely to be wider than narrower.

Crucially, this is not achieved at the expense of profitability. Dajin's export gross margin reached 39.36% in the first half of 2026, an increase of 8.67 percentage points year-on-year. The company is expanding its margin substantially while gaining share, rather than discounting to buy position. This indicates that it retains considerable room to absorb a moderate trade measure and continue competing.

Vertical integration has removed Europe's main entry barrier

Dajin's advantage extends well beyond factory cost. It has systematically dismantled the constraint that previously insulated European yards. Specialist heavy-transport capacity is the recognized bottleneck in this market: vessels capable of carrying XXL monopiles are scarce and typically booked one to two years in advance. Dajin now operates its own fleet. Its first 40,000 dwt deck carrier entered service in February 2026 and has already completed two monopile voyages to European ports, with further vessels to follow.

The company has moved downstream as well, securing four wind port terminals in Germany, Spain and Denmark spanning the North Sea, Baltic and Atlantic corridors, and winning a first marshalling contract worth 1.34bn RMB in November 2025 covering manufacture, transport, storage and assembly.

Manufacturing capacity underpins this position: approximately 700,000 metric tones a year across two bases, with rolling capability of up to 16 metres in diameter against an industry average of around 12.5 metres, and specification for floating foundations.

Trade defence and economic security now shape the outlook

Four regulatory developments will determine whether Dajin's leading position in Europe proves durable.

  • Anti-dumping on foundations. Sif has lodged a complaint with DG TRADE concerning offshore steel structures. A case handler has been appointed and initial feedback is expected in the fourth quarter of 2026.
  • The EU Steel Overcapacity Regulation: In force since July 2026 with a 50% out-of-quota duty, it currently excludes monopiles on classification grounds. However, the Commission must assess by 30 June 2027 whether to extend its scope to downstream products containing significant quantities of steel, a category that could encompass offshore wind foundations.
  • CBAM applies definitively from 2026 and does extend to foundations, adding a carbon cost to a product made of roughly two-thirds steel by weight.
  • The Net-Zero Industry Act permits non-price resilience criteria in auctions, which are capable of excluding suppliers irrespective of tariffs.

The balance Europe has to strike

Europe requires roughly 7 GW of new offshore wind capacity a year to 2030, and its own yards cannot deliver it, constrained as they are by land, ports, skilled labor and cost. Developers including Ørsted and RWE turned to Chinese supply precisely because European fabricators failed to deliver on schedule. Restricting that supply would raise project costs and place timetables at risk; permitting it entrenches dependence on Chinese manufacturing for critical energy infrastructure, at a time when Europe's incumbents are operating under financial pressure.

Dajin's hedge is to build inside Europe. It has allocated 20% of its listing proceeds to a European assembly base. European manufacturing would blunt origin-based duties and satisfy local-content criteria simultaneously. In that case, trade defense alone would be unlikely to alter the competitive position, unless restrictions based on ownership and control were introduced alongside it.
