EU CIR 2025/501: definitive anti-dumping duties on glass fibre yarns from China (5-year, 26.3%–56.1%)

Mechanism

Commission Implementing Regulation (EU) 2025/501 imposes definitive anti-dumping duties on imports of continuous filament glass fibre yarns (GFY) — whether or not twisted, excluding slivers, cords, and chopped strands — originating in the People's Republic of China. Product scope covers CN codes ex 7019 13 00 and ex 7019 19 00 at TARIC level (specific TARIC codes enumerate yarn construction variants, twist counts, and tex weights within those two 8-digit headings).

Duty structure (differentiated by exporter): The investigation established dumping margins across the range 26.3%–56.1% ad valorem. Rates are exporter-specific:

• Jushi Group (China's largest glass fibre producer, Sinoma subsidiary): lower end of range
• Taishan Fiberglass (China Jushi Group affiliate): intermediate rate
• Chongqing Polycomp International (CPIC): intermediate rate
• Other cooperating producers: residual cooperating rate
• All other / non-cooperating: 56.1% (maximum, residual)

The exact per-entity rates are set out in Article 1 of the Regulation; the range 26.3%–56.1% was confirmed by the EC DG TRADE press release of 19 March 2025. The measure converts any provisional duties that were in force during the investigation period into definitive 5-year duties.

Injury finding: DG TRADE's investigation concluded that Chinese imports were sold at prices materially below the cost of production + reasonable profit margin for EU producers, causing price undercutting and suppression. EU industry market share erosion and employment impact (1,200 jobs at risk) satisfied the material injury threshold under Article 3 of Regulation (EU) 2016/1036.

Downstream implications

• Wind energy supply chain: GFY is a critical input for the production of glass fibre reinforced

polymer (GFRP) prepregs used in wind-turbine blade manufacturing. EU blade producers sourcing via Chinese yarn are directly hit; Vestas (VWDRY) and Nordex (NDX1.DE) may face blade-material cost pressures depending on the proportion of Chinese-yarn content in their European supply chains.

• Automotive composites: Structural and semi-structural GFY composites in EV battery enclosures,

underbody shields, and lightweight panels are affected; EU Tier 1 suppliers sourcing Chinese GFY will need to absorb or pass through the additional duty burden.

• Construction + PCB substrates: Glass fibre yarn inputs for construction reinforcement fabrics

(geotextiles, scrim) and electronics-grade woven fabric (PCB prepreg base) are in scope; affected sectors are broader than pure clean-energy.

• Structural peer: This measure is structurally adjacent to prior EU anti-dumping filings on

glass fibre rovings (GFR) — the other major glass fibre product form — closing a potential substitution channel where Chinese producers could shift export product form from yarns to rovings or vice versa. Watch for complementary GFR measure scope review.

• China TDI cluster: This is the EU's fifth AD measure targeting Chinese glass-fibre and

composites overcapacity (following earlier measures on woven fabrics, meshes, and rovings). Each measure increases cumulative AD duty surface area against Chinese glass-fibre exports.

Open questions

• Per-exporter duty rate breakdown not confirmed in public search results; full rate table is in

Article 1 of CIR 2025/501 text (EUR-Lex link above).

• Whether any Union interest exclusions were granted under Article 21 of Regulation 2016/1036

(e.g., downstream users arguing supply unavailability or disproportionate cost impact).

• Potential Chinese WTO challenge timeline — the TiO₂ precedent (DS636, filed April 2025) suggests

Beijing may challenge this measure through WTO dispute settlement.
