I. Why Guangxi Merits Separate Study

Guangxi's non-metallic mineral products industry is not a uniformly distributed provincial sector. It comprises three relatively independent industrial belts layered on top of one another: a cement belt centered on southern Guangxi, a daily ceramics belt anchored by Beiliu, and a calcium carbonate deep-processing belt radiating outward from Hezhou. The three differ in resource endowment, market orientation, and transformation path, yet together they form the largest manufacturing sub-sector by volume in Guangxi's industrial base.

According to the Fifth National Economic Census bulletin published by the Guangxi Bureau of Statistics in 2024, non-metallic mineral products enterprises account for 11.5% of all industrial legal entities in the region and 9.8% of the manufacturing workforce — the second-largest manufacturing employer after food and beverage.

II. Cement: Second-Largest Clinker Base Nationally, But the Trap Is Set

Guangxi's cement industry carries considerable national weight. According to the 2024 national clinker capacity rankings published by China Cement Network, Guangxi's clinker capacity reached 108.26 million tonnes, placing the province second nationally behind only Anhui. The region operates 79 clinker production lines, with 39 lines in the 3,500–4,500 tonnes-per-day range constituting the dominant capacity tier.

Scale, however, does not translate to profitability. Guangxi's cement output in 2024 was approximately 94.92 million tonnes, down roughly 5 million tonnes from 2023, a decline of about 5%. Most months of the year saw year-on-year output contraction, with March recording a single-month decline approaching 27%. Capacity utilization stood at around 69%, and severe overcapacity has become an industry consensus.

China Resources Building Materials Technology is the leading player in Guangxi's cement market with approximately 26% market share, followed by Conch Cement at around 15% and Red Lion Cement at around 10%. The three together control roughly half of regional capacity, but this concentration has not reversed the demand downturn.

Guangxi's 14th Five-Year Plan for the building materials sector explicitly states that new clinker capacity will in principle no longer be approved, and calls for guiding enterprises to reduce excess and retire obsolete capacity. Multiple rounds of coordinated kiln stoppage were implemented across the region in 2024, with certain months recording output declines exceeding 15% year-on-year. The de-capacity path is clear; when genuine clearance will arrive remains an open question.

III. Beiliu Ceramics: Guangxi's Only Scaled Daily Ceramics Production Zone

Beiliu, located in the southeastern Guangxi prefecture of Yulin, is one of the few county-level production zones in China whose primary industry is daily-use ceramics. Beiliu ceramics cover daily ware, art ware, and specialty ceramics, with a vertically integrated chain spanning raw material extraction, body forming, kiln firing, and trade support.

According to publicly available data, as of end-2023 Beiliu had 44 ceramic manufacturing enterprises, of which 34 were above designated scale, alongside approximately 60 associated trading, raw material, and equipment enterprises. The full industrial chain employed around 45,000 workers and generated annual output value of approximately 5.2 billion CNY. From January to October 2024, above-scale ceramic enterprises recorded total output value of approximately 1.83 billion CNY, with import-export volume of approximately 300 million CNY over the same period.

Beiliu ceramics derive their competitive advantage from long-accumulated craft traditions and a relatively complete local supplier base — not from a single resource advantage. This positions Beiliu as one of the few export-oriented production zones within Guangxi's non-metallic mineral products sector, with products reaching Southeast Asia, Europe, and other markets. The cluster drew international media attention as recently as November 2024, with China News Service running a dedicated feature.

IV. Hezhou Calcium Carbonate: Upgrading From "Heavy Calcium Capital" to Advanced Materials

Hezhou in eastern Guangxi sits atop exceptionally rich limestone deposits. In calcium carbonate mineral powder processing, Hezhou has established a nationally dominant position and carries the designation "China's Heavy Calcium Capital."

According to the 2024 Annual Development Report on Guangxi's Calcium Carbonate Industry, the region had 472 calcium carbonate processing enterprises by 2024, including 172 above designated scale — a year-on-year increase of approximately 21%. Calcium carbonate powder output reached approximately 39.6 million tonnes, up more than 6% year-on-year, with industry output value sustained above 30 billion CNY.

Hezhou's position within these figures is particularly pronounced. As of 2024, the city had approximately 229 above-scale stone calcium carbonate enterprises, heavy calcium powder capacity of around 37 million tonnes, actual production exceeding 18 million tonnes — representing over 80% of Guangxi's total heavy calcium output — and a comprehensive output value exceeding 35 billion CNY.

Hezhou is pursuing two upgrade directions: first, extending downstream into masterbatch (plastic filler masterbatch) manufacturing, positioning toward a "China Masterbatch Capital" designation; second, entering the biodegradable new materials space, embedding local calcium carbonate resources into the packaging materials supply chain. The depth and pace of this transition will determine whether Hezhou can graduate from raw material supplier to materials solution provider in the national calcium carbonate landscape.

V. Beihai Photovoltaic Glass: An Emerging Incremental Sector

Guangxi's glass industry remains relatively modest in scale, but the Beihai Tieshan East Port Industrial Park is constructing what aims to be a trillion-yuan cluster centered on photovoltaic glass and high-end architectural glass. According to publicly disclosed project plans, the park has a total planned investment of approximately 560 billion CNY, with a target annual output value of around 780 billion CNY upon full completion, encompassing green chemicals, electronics, high-end glass and photovoltaic materials, and new materials.

For the glass segment specifically, the park remains largely in construction and investment attraction phases, and it has some distance to travel before forming a complete regional industrial cluster. That said, if photovoltaic glass capacity lands as planned, Beihai's coastal location and policy advantages as a node in the New International Land-Sea Trade Corridor could generate meaningful incremental volume for Guangxi's overall non-metallic mineral products profile.

VI. Upstream Supply Chain Logic

Guangxi's non-metallic mineral products industry draws on a broad upstream supply base: cement lines require coal, slag, additives, and kiln equipment; ceramics enterprises rely on natural gas, ceramic pigments, glazes, and forming machinery; calcium carbonate processing demands grinding equipment, surface treatment agents, and packaging materials; glass manufacturing involves soda ash, silica sand, and high-temperature furnace systems.

These procurement needs are continuously met by specialized suppliers across China. Sales teams focused on winning factory customers in Guangxi can use Tianxia Gongchang to filter factory directories and decision-maker contact details by region and industry across cement, ceramics, mineral processing, and related sub-categories.

VII. The Industry's Actual Condition

Taken together, Guangxi's non-metallic mineral products industry is in a period of differentiated transition: cement is the largest sub-sector by volume but faces the most severe pressure, with no obvious near-term relief; ceramics, centered on Beiliu, has formed a production zone with meaningful export competitiveness, though still limited in absolute scale; calcium carbonate, with Hezhou at its core, offers Guangxi's clearest opportunity to move beyond a resource-extraction model, and whether the downstream extension into masterbatch and new materials succeeds warrants continued tracking.

What makes Guangxi unusual as a production region is that it simultaneously carries cement's overcapacity burden and calcium carbonate's structural upgrade potential. This coexistence precisely reflects the broader tension running through China's traditional non-metallic mineral products sector at this stage of development.
