USD-based benchmark valuation for imported European aromatic products

Note: Calculations are based on the daily closing price of Brent crude, applying a fixed cost estimation formula (derived from standard USD contract settlement formulas), and incorporating changes in daily premiums/discounts.

The benchmark prices in the table use imported European mixed aromatics as the reference. For USD benchmark prices in Asia-Korea and other regions, product density must be taken into account. Contract negotiations reflected in the table are settled in USD; the RMB benchmark price is a reference value converted at the daily exchange rate. These prices serve solely as references for USD contract settlements and do not represent spot transactions on the day. For goods sourced via letter of credit issuance on behalf of others, the handling fees charged by the issuing party must be considered separately.
