As a professional manufacturer with 32 years of experience in pipe and fitting production, Shandong Jianlong Plastics Co., Ltd. is committed to sharing timely and in-depth industry updates with its global partners. Below is our analysis and interpretation of the Chinese HDPE market trend in December 2025, for your reference:

The operating rate of major domestic petrochemical enterprises remains at 78%-82%, with new capacity gradually being released, and the supply of general-purpose HDPE materials (such as fiber grade and injection molding grade) is sufficient. On the import side, the supply of goods from the Middle East and Southeast Asia continues to flow into the Chinese market due to their cost advantages, further exacerbating the supply pressure. Market inventory increased by about 12% month-on-month compared to November.

In downstream application areas, pipes and fittings (accounting for 35% of HDPE demand) saw a month-on-month decrease of 8%-10% in order volume due to construction restrictions in northern winters; the packaging and injection molding industries are also in their traditional off-season, with enterprises mainly purchasing based on immediate needs and showing a weak willingness to stock up in bulk, making it difficult for overall demand to provide effective support.

The average domestic HDPE market price in November has dropped by 3.2% compared with the previous month. After entering December, the contradiction between supply and demand has not been alleviated, and the price still shows a slight downward trend. Up to now, the mainstream quotation of HDPE wire drawing grade is 8900-9200 CNY/ton, a decrease of about 1.5% compared with the beginning of the month.

International crude oil prices fluctuated between $75 and $80 per barrel, influenced by global economic expectations, failing to provide strong cost support for the HDPE market. Profit margins for domestic ethylene-based HDPE producers narrowed, but due to ample supply, companies were cautious about adjusting prices.

With the continued implementation of domestic "stabilizing growth" policies, the subsequent completion of infrastructure projects may stimulate demand for HDPE pipes to some extent, but the short-term transmission effect is limited. At the same time, under the background of stricter environmental protection policies, the production capacity of some small recycled HDPE enterprises is limited, which has little impact on the virgin HDPE market.

China's HDPE exports are mainly directed to Southeast Asia and Africa. In December, overseas market demand was stable, and export prices were slightly more advantageous than those in the domestic market. Some companies alleviated inventory pressure through exports, and HDPE export volume is expected to increase by 5%-8% month-on-month.

In summary, the Chinese HDPE market will remain in a state of oversupply in December 2025, with prices likely to continue their narrow downward trend until a substantial improvement in the supply-demand relationship occurs.

For global partners, Shandong Jianlong Plastics, based on 32 years of production experience, offers the following suggestions:

1. For short-term purchases, adopt a "small batch, frequent" strategy to mitigate price fluctuation risks;

2. For long-term order needs, you can lock in cooperation prices with our company to ensure supply stability;

3. For HDPE materials specifically for pipes (such as PE100 grade water supply pipe raw materials), our company can provide customized production services, optimizing product formulations to meet the standards of different countries and regions (such as ISO, ASTM, etc.) based on export requirements.

Shandong Jianlong Plastics consistently provides global customers with HDPE pipe, fitting, and raw material solutions with stable quality and reasonable prices.
