5. Related Product Markets

Urea: The domestic urea market showed a high-level volatile pullback today. Production costs at urea enterprises remain high, providing underlying support for prices. However, as offers continued to climb, downstream demand has followed up sluggishly and purchasing turned cautious. In addition, plants previously under maintenance have gradually resumed operation, lifting daily output and keeping supply pressure in place. As a result, the domestic urea market has experienced a volatile correction over the past two days, although most producers still keep quotes stable with a strong willingness to support prices. In the very short term, as demand-side follow-through remains slow, producers are likely to soften quotes and proactively collect orders, potentially ushering in a new round of market adjustment.
