January 23 (Reuters) - On January 23, Shandong Lianyi lowered its formaldehyde price by 5 yuan/ton, quoting 1,000 yuan/ton ex-factory cash payment. Chempricehub's analysis of formaldehyde: Bull-bear score: -1. The spot price of formaldehyde decreased by 5 yuan/ton to 1,000 yuan/ton, indicating ample market supply or weak demand, which may exert short-term pressure on spot prices. The decrease is relatively small, representing a general bearish factor, but subsequent supply-demand dynamics should be monitored.
