I. Why Shandong's Chemical Fiber Industry Warrants Attention

In China's chemical fiber landscape, Shandong is not the most prominent province — Zhejiang and Jiangsu have long held the top positions by output — but the province stands out for the remarkable divergence within its own sector. On one end sits Weifang's established regenerated cellulose fiber industry; on the other, a carbon fiber composite cluster centered on Weihai that has been designated a key cluster within Shandong's provincial "Ten Dominant Industries" initiative. This dual structure, spanning both legacy manufacturing and advanced new materials, gives Shandong a distinctive analytical profile.

In 2024, China's total chemical fiber output reached 74.75 million tonnes, up 8.8% year-on-year, accounting for over 60% of global production. Shandong enterprises have navigated this environment by absorbing incremental growth while contending with the shared industry-wide pressures of overcapacity and price decline.

II. Geographic Clusters: Three Poles — Weifang, Weihai, Yantai

Shandong's chemical fiber production is geographically concentrated in three distinct industrial hubs.

Weifang is the traditional center of regenerated cellulose fiber in Shandong. Hengtianhailong (Weifang) New Materials Co., Ltd., founded in 1984, produces approximately 170,000 tonnes per year of differentiated and conventional viscose staple fiber, alongside 30,000 tonnes of polyester cord fabric and canvas, and 12,000 tonnes of high-modulus low-shrinkage polyester industrial filament. The company is recognized as an innovative enterprise in Shandong Province and is regarded as a leading R&D and production base for new-generation regenerated cellulose fibers in China.

Weihai represents Shandong's most strategically significant growth pole in chemical fiber. Built around Guowei Composite Materials Co., Ltd. (300699.SZ), Weihai has developed a carbon fiber composite materials cluster, officially designated among Shandong's provincial "Ten Dominant Industries" geese-formation clusters. By end-2023, the cluster had aggregated more than 50 above-scale enterprises along the carbon fiber value chain, driving Weihai's carbon fiber industry revenues to over 27 billion yuan. The cluster is actively extending into aerospace, wind power, and low-altitude aviation applications.

Yantai is the main base for high-performance specialty fibers. Taihe New Material Group (002254.SZ) is headquartered in Yantai, with its meta-aramid fiber capacity concentrated locally. The company was the first in China to achieve commercial production of spandex, meta-aramid, para-aramid, and aramid paper, and the world's first to produce smart fiber at commercial scale.

III. Leading Enterprises: Three Listed Companies Define the Axis

The competitive landscape among Shandong's chemical fiber leaders is relatively well-defined, with three publicly listed companies each dominating their respective segment.

Guowei Composite Materials is the most prominent carbon fiber enterprise in Shandong and one of the most significant in China. Starting from fishing rod manufacturing, the company spent more than three decades building technical competencies before becoming the first A-share listed company in China's carbon fiber sector, and today one of the most complete along the domestic carbon fiber value chain. In 2024, the company reported revenue of 2.45 billion yuan and net profit attributable to shareholders of 741 million yuan. Carbon fiber and fabric sales totaled 2,074.82 tonnes, with T800-grade product revenues growing 64.64% year-on-year, reflecting a clear trend toward higher-end product mix. Notably, its wholly-owned subsidiary Weihai Tuozhan signed a multi-year contract worth 3.66 billion yuan with a strategic customer covering 2024 to 2027. However, overall carbon fiber segment revenue declined 12.91% year-on-year in 2024 — the company's first notable profit contraction since listing, reflecting sector-wide supply pressure.

Taihe New Material is a dual-category leader in high-performance specialty fibers. In 2024, spandex output reached 71,851 tonnes and aramid output approximately 20,882 tonnes, both setting historical records in volume; however, sustained price declines compressed margins sharply, with profits falling substantially compared to prior years. From a global standpoint, Taihe ranks second globally by meta-aramid capacity and third by para-aramid capacity. The company is actively developing aramid-coated battery separator films as a new growth driver within the new energy supply chain.

Hengtianhailong (Weifang) focuses on higher-value differentiated viscose staple varieties — including dyed and functional fibers — while continuously advancing energy efficiency and green production processes. The company has also extended downstream into aramid fabric and industrial textile products, pursuing limited vertical integration along the industrial chain.

IV. Supply Chain Structure

Shandong's chemical fiber value chain exhibits significant outward dependency at both ends.

Upstream: Viscose staple fiber relies on cotton pulp and wood pulp as primary raw materials. Shandong's domestic cotton resources provide some support, but wood pulp is heavily import-dependent. Carbon fiber precursor (PAN-based raw filament) remains a critical bottleneck; Guowei Composite has addressed this partly through in-house precursor production. Spandex raw materials — PTMEG and MDI — are dominated by a small number of large chemical producers, with pricing power concentrated outside Shandong.

Downstream: Viscose staple fiber flows primarily to yarn-spinning mills in Shandong and in Jiangsu and Zhejiang. Carbon fiber downstream applications include defense, wind turbine blades, sports and leisure goods, and the early-stage low-altitude aviation sector. Aramid fibers serve high-end applications including ballistic protection, firefighting garments, optical cable reinforcement, and new-energy battery separators — a domain with meaningful import-substitution potential.

V. Structural Challenges and Transformation Pressure

The core tension within Shandong's chemical fiber sector in 2024 is structural rather than cyclical.

Conventional viscose staple fiber faces dual pressure from persistent overcapacity and tightening environmental standards. The rising competitiveness of solvent-spun Lyocell fiber — with its lower environmental footprint — places sustained cost pressure on traditional sulfate-process viscose producers. Some capacity has entered a consolidation and rationalization phase.

In carbon fiber, rapid domestic capacity expansion by multiple producers has fundamentally shifted the supply-demand balance away from the military-driven premium pricing of the prior period toward a more contested civilian market. Guowei Composite's 2024 profit decline is indicative of a broader sector transition from protected defense pricing toward open-market competition.

The spandex sector similarly suffers from overcapacity, as evidenced by Taihe New Material's sharp profit compression despite record production volumes.

The potentially transformative next chapter depends on the pace of market penetration in high-end applications: aramid-coated lithium battery separators, carbon fiber structural components for low-altitude aircraft, and Lyocell fiber displacing traditional viscose — all of these remain at the technology validation or early commercialization stage, with timelines and scale yet to be established.

VI. Two Trajectories

Shandong's chemical fiber story is, at its core, the parallel unfolding of two distinct industrial logics. Weifang's viscose operations pursue an existing-capacity optimization path — extracting value through process improvement and differentiated product development within a mature but pressured industry. Weihai and Yantai's carbon fiber and aramid businesses carry the strategic mandate of domestic substitution for advanced materials, accepting higher capital intensity and technical risk in exchange for defensible long-term positioning.

Neither trajectory has reached a resolution. The first asks how to remain profitable in a structurally oversupplied market; the second asks how to anchor a commercially sustainable model between recovering defense demand and intensifying civilian price competition. The real dynamics of Shandong's chemical fiber industry lie within this unresolved structural tension.

Sales teams focused on chemical raw materials, fiber inputs, or industrial technical textiles — seeking to reach upstream factory customers in Shandong — can use Tianxia Gongchang to filter factory directories and key decision-maker contacts by province and chemical fiber sub-segment for targeted outreach.
