In 2025 China's gypsum board — the dominant form of gypsum products — produced about 3.07 billion m² nationally, a market worth RMB 15–20 billion. And a single company, BNBM Group (000786.SZ), took roughly 69% of it: its gypsum-board revenue was RMB 11.96 billion, more than half of the group's RMB 25.28 billion total.

A second number is sharper still: BNBM's "Taishan" brand alone accounts for 60%–70% of its internal gypsum-board sales. In other words, what looks like "competition in the gypsum-board industry" is mostly one group arranging its own high/mid/low tiers.

This one is written for people in building materials, gypsum-product trading, or anyone hunting opportunity along the "industrial by-product gypsum → green building material" chain. Because on the surface gypsum products are an ordinary real-estate-late-cycle material; underneath runs a hard logic — "whoever controls the feedstock controls the cost" — and that logic is being rewritten by industrial by-product gypsum.

First, see the board clearly: one giant, several strong players, CR4 ≈ 80%

Laid out, China's gypsum products (gypsum board as the overwhelming core) is essentially a "one giant, several strong" structure:

  • Concentration: "one giant, several strong", CR4 ≈ 80%; BNBM alone holds ~69% (Ping An Securities)
  • BNBM gypsum-board capacity / output: 3.663 bn m² / 2.12 bn m² (2025, Ping An Securities)
  • BNBM gypsum-board revenue: RMB 11.96 bn (2025, nearly half of group revenue, Ping An Securities)
  • National gypsum-board output (derived): ~3.07 bn m² (back-solved from BNBM's 2.12 bn m² ÷ 69%)
  • Average ex-works price: RMB 5.57/m² (2025; RMB 6.39/m² in 2022 — the price centre is drifting down, Ping An Securities)
  • Three foreign players combined: Saint-Gobain + Knauf + USG Boral ≈ 8% (BNBM bond-rating report, 2021 basis)

What it means for you: this is a "leader sets the price, the long tail follows" market. A 69% share means BNBM holds the de facto price anchor — when in March 2025 Taishan Gypsum issued a price letter (Taishan series +RMB 0.5/m², non-Taishan +RMB 0.3/m²), the whole industry's ex-works prices moved with it. In this market the first thing to watch is not demand but BNBM's moves.

Tier 1: the sibling brands — Longpai, Taishan and Mengpai are not rivals, they are one group's internal tiers

The easiest mistake is to treat BNBM's brands as "competitors".

The reality: Longpai (premium), Taishan (the mid-tier volume workhorse), Mengpai (low-end) and Ousong (same group) all sit on one group's books. Taishan takes 60%–70% of internal sales; Longpai attacks landmark public buildings (the Winter Olympics, the Great Hall of the People); Mengpai covers ~10% at the bottom.

What it means for you: when discussing "Taishan Gypsum's peers", the real external rivals are not Longpai or Mengpai — they are BNBM's arrangements to cover different price bands with different brands and avoid cannibalising itself. Writing sibling brands into a report as competitors is the classic rookie error, and it directly overstates "competitive intensity".

Tier 2: foreign players in China — Saint-Gobain and Knauf, the ~8% premium perch

  • Saint-Gobain (China) Investment Co. / Gyproc: first line in Shanghai in 2000 (~20m m²), Changzhou line in 2006 (~30m m²); from the French Saint-Gobain group (founded 1915), the top foreign tier.
  • Knauf Building Systems (Tianjin) / KNAUF / Sheetrock: entered China in 1996, Tianjin + Shanghai bases, 220 bases in 70 countries; founded in Germany in 1932, acquired USG Boral outright in 2021.

The three foreign players combined hold ~8%, but note: after 2021 USG Boral is no longer an independent player — today only Saint-Gobain and Knauf remain as truly independent foreign brands.

What it means for you: foreign players don't fight on price; they fight for premium public buildings, foreign-invested projects and landmark works — that is Longpai's home turf, not Taishan's mid-tier volume market. To break into the premium segment you face not "cheaper is fine" but decades of project track record and on-site service that Saint-Gobain / Knauf have banked.

Tier 3: the local second tier — JASON expands hardest, BAIER and LUOFEIER hold their regions

  • JASON Gypsum Board (Jiaxing) / JASON (Wing Shing Group, HK, wholly foreign-owned): investment over USD 100m; four bases in Jiaxing/Huizhou/Changchun/Chongqing (Chongqing online 2026); five lines, ~160m m² annual capacity
  • Shandong BAIER Building Materials / BAIER: ~120m m²/yr of positioned paper-faced gypsum board, 200k t/yr of steel studs; founded 2002, Shandong famous trademark, co-author of the JC/T paper-faced gypsum board standard
  • LUOFEIER Building Materials (Shenyang) Group: founded 2007, bases in Shenyang + Jiangsu Huai'an + Hebei
  • TUBAO (Dehua Tubao Decorative Materials, 002043.SZ): Shenzhen-listed, mainly eco-board/decorative board, gypsum board as an extension
  • Qiannianzhou, Weiye (Shenchui), Suihua, Jinqiao: decorative-board leaders extending in / Guangdong regional brands

What it means for you: within this tier JASON is the only "aggressive external player" — its Chongqing base coming online in 2026 pushes total capacity to 160m m², one of the few local forces expanding against the cycle and daring to contest BNBM's project channels. The rest hold their regions on price and local relationships, unable to shift the aggregate picture.

Who actually threatens whom: a threat ranking

Rank the three external tiers by threat to Taishan Gypsum (the mid-tier volume battleground):

Knauf ≈ Saint-Gobain (premium spillover) > JASON (local expansion) > BAIER / LUOFEIER (regional low-mid)

  • Knauf and Saint-Gobain spill down from the premium end; high brand and technical barriers make them the "invisible but hardest" rivals;
  • JASON pushes up through project channels, expanding hardest — the "visible and most active" local threat;
  • BAIER and LUOFEIER stay in the regional low-mid price band, with limited overlap with Taishan's main battlefield.

Internally Longpai reaches up and Mengpai down, covering everything with Taishan; external players can hardly shake the aggregate advantage in the short term.

Gypsum products are more than board: board dominates, but the feedstock logic matters more

"Gypsum products" is a big family: gypsum board (paper-faced / non-paper), plaster / gypsum powder, gypsum blocks, decorative cornice, gypsum-based self-levelling. But by volume gypsum board is unquestionably the core — BNBM's RMB 11.96bn gypsum-board revenue is the anchor of this segment's value.

The real "hidden line" of this segment is feedstock. Raw material is over half of board cost, face paper ~40%, and the gypsum itself has long shifted from natural gypsum to industrial by-product gypsum: every BNBM line built after 2003 runs on power-plant flue-gas-desulphurisation (FGD) gypsum; its Xiangyang base uses 100% industrial by-product gypsum (phosphogypsum), each board QR-traceable. With 100+ production bases nationwide it keeps the sourcing radius within 100 km — the physical basis of BNBM's cost moat.

On the tariff side, the main HS code for paper-faced gypsum board is 68091100 (MFN 15%, VAT 13%, export rebate 13%); upstream FGD / phosphogypsum map to 25201000 / 25202000, requiring a separate feedstock view for reverse supply-chain tracing.

What it means for you: to play in gypsum products, don't just watch the finished-product price war — the real cost swing is "who can secure stable, cheap, nearby industrial by-product gypsum". A location next to a power plant or phospho-chemical park is itself an asset.

The statistical-basis traps: don't add these two numbers

Writing this industry, two statistical-basis pitfalls must be flagged (the recon verdict was WARN — analysable but caveat-required):

  • Taishan "53%" vs BNBM "69%": several brand rankings put Taishan's domestic share at ~53% — that is the "brand basis"; BNBM group's 69% is the "group basis". They must not be added; report uniformly as "BNBM group ≈ 69%, of which Taishan is the largest single brand".
  • The foreign "8% combined" is a pre-2021 basis: USG Boral was acquired by Knauf in 2021; today only Saint-Gobain and Knauf are independent foreign players, so 8% needs downward revision to the latest structure.

What it means for you: any stacked statement like "Taishan 53% + BNBM 69%" is a statistical-basis error. The first step to a clean industry report is unifying the denominator.

Risk list: the things this market bites on

  • Property-completion downturn: gypsum-board demand tracks housing completions tightly; completions kept falling from 2024, down 16.9% YoY cumulatively in the first four months of 2025, dragging the total; the renovation market (2.3bn m² of second-hand-home transactions across 30 cities in 2024, +6% YoY) partially offsets but cannot reverse the trend.
  • Price-centre drift-down: ex-works price fell from RMB 6.39/m² (2022) to RMB 5.57/m² (2025); the industry "trades price for volume", squeezing long-tail margins.
  • Face-paper bottleneck: face paper is ~40% of cost, an oligopoly (top 4 > 90% of capacity). BNBM backs itself with its own paper mill (Taihe Paper, 600k t/yr); smaller makers have weak upstream bargaining power.
  • Ongoing foreign M&A: Knauf swallowing USG Boral in 2021 is just one example; concentration in the premium segment keeps rising, narrowing local brands' window to move up.
  • Solid-waste policy is a double-edged sword: "produce by what you utilise" / "produce by what you discharge" rules for industrial by-product gypsum (e.g. Hubei requires > 65% phosphogypsum utilisation by 2025) send feedstock dividends to players near the waste source, but can also reshuffle capacity the moment an environmental inspection tightens.

Three routes — pick by your position

  • If you sell industrial by-product gypsum / feedstock: your customer is not "a gypsum-board plant" but "the gypsum-board plant within 100 km of you". Half of BNBM's moat is nearby feedstock; whoever can supply stable, low-impurity FGD / phosphogypsum controls the upstream of this chain.
  • If you make gypsum board / a regional brand: don't contest Taishan's mid-tier volume market — that is BNBM's home turf of scale-amortised cost. Do the part it can't or won't do economically: premium public buildings (against Saint-Gobain / Knauf's track record), decorative / custom board (against design), and regional solid-waste board near the waste source (against feedstock dividends).
  • If you trade / go overseas: BNBM is accelerating globalisation (SE Asia, Central Asia, Middle East, Europe, the Mediterranean rim), overseas revenue RMB 417m in 2024 at 23.91% gross margin; but gypsum board is easy to export and prone to overcapacity, so smaller firms should eye capacity-short regions like Africa / Central Asia rather than clash with the giant in mature markets.

One last point

China's gypsum products are not "a competitive market with many players" but a market where 69% belongs to one company and the rest hunt for gaps inside the price bands it has drawn. The variable worth watching is not who added another line, but: after industrial by-product gypsum rewrites the feedstock cost, who can grow the next board out of "waste".
