Core Insights - The core objective of the styrene futures quality inspection was to ensure that the delivery quality standards of styrene futures align with the actual circulating quality in the spot market [2] Group 1: Inspection Overview - The inspection covered styrene goods circulating in the domestic spot market, including both mainstream products from ethylbenzene dehydrogenation and those from smaller, quality-variable sources like pyrolysis gasoline extraction [2] - The testing indicators were based on the officially released "Styrene Delivery Quality Standards (F/DCE EB001-2019)," which included nine key metrics: appearance, purity, polymer content, peroxide, total aldehyde, color, ethylbenzene, inhibitor (TBC), and sulfur content [2] - The inspection concluded that, except for the extracted source styrene, the majority of products in the market met the futures delivery quality requirements, leading to the addition of a clause for sulfur content ≤1mg/kg in the official standards [2] Group 2: Market Impact - The inspection results directly supported the formulation of the styrene futures delivery standards, enhancing the operability and risk management capabilities of the contracts [3] - The standards adopted existing spot market rules, which reduced hedging costs for companies; the inspection data also provided a benchmark for resolving future quality disputes, thereby increasing market trust in futures instruments [3]
