This market resolves YES if China's trailing 14-month Eu export volume exceeds 140000 kg on June 30, 2026.

What is being measured: Cumulative Chinese exports of all Eu-containing products (metal, oxides, compounds) under GACC HS codes 280530 and 2846, for the 14-month period ending 2 months before June 30, 2026. The 2-month lag ensures GACC has published data for all months in the window.

Measurement window: 14 calendar months ending the second-to-last month before June 30, 2026. For December 31 settlement: November (prior year) through October (current year).

Data timing: GACC publishes monthly bilateral trade data approximately 6 weeks post-reference month. All 14 months in the window are published before settlement.

YES if:

• GACC and/or UN Comtrade data confirms cumulative Eu exports (HS 280530 + HS 2846) exceed 140000 kg for the applicable 14-month window

NO if:

• Cumulative Eu exports for the window are ≤ 140000 kg per GACC/Comtrade data

• If GACC data is unavailable for any month in the window, UN Comtrade mirror data from destination country imports will be used as a proxy; if proxy data also unavailable, the affected months are treated as zero exports

Unit note: Convert all data to kg. GACC may report in tonnes (×1,000) or metric tonnes. Sum HS 280530 (metal) and HS 2846 (compounds/oxides) series.
