China’s Net PE Imports Halve in Jan–Sep as Exports Reach Record High

China’s polyethylene (PE) trade experienced a major shift during the first nine months of 2026, as imports dropped to their lowest January–September level since 2016 while exports nearly tripled to a record high. The combined trend cut the country’s net PE import requirement by more than half, highlighting China’s growing reliance on domestic production and its expanding role as a regional supplier.

September brought a partial recovery in imports, which climbed sharply from August, while exports recorded a smaller monthly increase. Vietnam emerged as the leading destination for Chinese PE shipments, accounting for an unusually large share of total exports.

PE Imports Fall to Their Lowest Level in a Decade

China’s combined imports of HDPE, LDPE, LLDPE and mLLDPE declined by 31% year on year to approximately 7.26 million tons between January and September 2026. This was the lowest volume for the corresponding period since 2016, reflecting the growing impact of domestic capacity expansion on import demand.

The decline points to a structural change in China’s PE market. New domestic production capacity has increasingly replaced imported material, while supply disruptions, higher freight costs and logistics uncertainty linked to the US–Iran conflict have further affected the competitiveness of overseas shipments.

However, imports recovered strongly in September. Volumes increased by 41% from August, a sharper rebound than the modest gains recorded in July and August. Despite this improvement, September imports remained 21% below the level seen in the same month of 2025.

The monthly recovery indicates that imported material regained some ground, but it remains uncertain whether this momentum will continue. The substantial year-to-date decline still points to a market increasingly supported by domestic supply.

Saudi Arabia was China’s largest PE supplier in September, accounting for 19% of total imports, followed by the US at 18% and South Korea at 11%. The US share doubled from 9% in September 2025 despite the overall contraction in imports. Across January–September, Saudi Arabia and the US jointly led the supplier rankings, each accounting for 17% of China’s total PE imports.

China’s PE Exports Nearly Triple to a Record

In contrast to declining imports, China’s PE exports expanded rapidly during the first three quarters of 2026.

Total exports rose by approximately 198% year on year to 2.54 million tons during January–September, nearly three times the volume recorded in the same period of 2025. This marked an unprecedented nine-month high for China’s PE export trade.

The surge was supported by export opportunities that emerged earlier in the year, when disruptions to Middle Eastern supplies and shipping routes prompted Asian buyers to seek alternative sources. China’s expanding domestic production base enabled local suppliers to meet some of this demand and strengthen their presence in Southeast Asian markets.

Although the exceptional export growth seen during the spring has eased, shipments have remained significantly above historical levels.

In September, PE exports increased by 4% month on month and surged by 126% year on year. The modest monthly rise followed a period of stabilization after shipments fell sharply from their record spring highs.

Vietnam was the leading destination, receiving 36% of China’s total PE exports in September, compared with 25% in August and 26% in September 2025.

Shipments to Vietnam increased by approximately 50% month on month, far exceeding the 4% growth in China’s overall PE exports. The additional volume sent to Vietnam was greater than the net increase in total exports, indicating that shipments to other destinations collectively declined during the month.

Net PE Imports Shrink by More Than 51%

The widening gap between China’s export growth and import decline is clearly reflected in its net PE trade position.

During January–September 2026, the difference between imports and exports narrowed to approximately 4.7 million tons, compared with 9.7 million tons in the same period last year. This represents a reduction of more than 51%, or around 5 million tons, within twelve months.

The contraction resulted from both lower import requirements and rapidly rising export volumes. China remains a significant net importer of PE, but its increasing domestic production is changing the balance between local supply, overseas purchases and material available for export.

September’s import recovery temporarily widened the monthly net import gap. However, it did not reverse the broader trend established during the first nine months of the year.

Is China Establishing a Higher PE Export Baseline?

The latest figures suggest that China’s PE exports may be settling at a substantially higher level than in previous years.

Monthly shipments exceeded 550,000 tons in April amid exceptional regional supply disruptions. Exports then declined sharply as Middle Eastern supply flows began to recover. Nevertheless, shipments stabilized at around 220,000–230,000 tons per month in July, August and September, remaining more than twice the levels recorded in the corresponding months of 2025.

This indicates that while the extraordinary spring export surge was temporary, China has not returned to its earlier export pattern.

The key question is whether this higher level of shipments can be sustained as regional supply conditions normalize and competition from established exporters intensifies. China’s expanding production capacity and reduced dependence on imports suggest that its role in regional PE trade could continue to grow, although future export volumes will depend on market demand, supply availability and competitive pricing.

Overall, China’s PE market is undergoing a significant structural shift. Record exports and lower imports have sharply reduced its net import requirement, raising the possibility that a higher export baseline will become a more permanent feature of the market.
