Fiber-cement board is the odd one out in Vietnam's building-materials story. Tiles, quartz, wood and aluminium all publish national output and export figures. Fiber-cement board (FCB) does not — and a good analyst says so rather than inventing a number. Here is what is actually verifiable, and how a buyer should read it.

The data-honesty point first

There is no single, reliable published figure for Vietnam's total FCB production capacity. National statistics bundle "cement" (Portland cement and clinker — a different product) separately from fiber-cement boards and sheets. So if a supplier or report quotes you a neat "Vietnam FCB capacity = X million m²," ask where it came from. The trustworthy signal is at the company and shipment level, not the national level.

What shipment data actually shows — and how to read it

Export-shipment records are the practical way to see who is actually producing and exporting FCB. They are also the easiest data to misread, because a shipment record names the exporting legal entity, not the brand on the board. Three traps to avoid:

  • The brand is not the exporter. Our own line, DURAGREEN®, ships under the company name VITD Co., Ltd. A buyer searching shipment databases for "Duragreen" finds nothing; searching the company name finds the shipments. The same gap applies to most Vietnamese makers who export under a trading entity.
  • One company can appear as several names. Hiệp Phú and Vĩnh Tường are the same business, not two competitors — counting them separately inflates any list of "Vietnamese fiber-cement makers." Its Duraflex brand was sold to Saint-Gobain years ago, so Duraflex is now a Saint-Gobain product line, not an independent Vietnamese one.
  • Some entries are simply mis-recorded. Trade databases carry transcription errors and one-off consignee names that never correspond to a real producer. If a name returns no company registration, no factory address and no product literature, treat it as noise rather than a supplier lead.

Netted out, Vietnam's fiber-cement export base is real and active — but it is a shorter list of genuine producers than a raw database export suggests.

The ecosystem around it

Vietnam's FCB sector sits on top of a deep cement and building-materials ecosystem. Regional major SCG operates a large cement and materials base in Vietnam (multi-million-tonne clinker and cement capacity, plus a push into low-carbon cement), which underpins the raw-material supply, technology and logistics that fiber-cement producers draw on.

What it means for project buyers

Because "capacity" is opaque, shift your due diligence to what you can verify:

  • Standard & category. Ask which ISO 8336 category the board meets (Category A/B, Class by bending strength), plus density and modulus of rupture (MOR). For roofing sheets, confirm the non-asbestos formulation.
  • A physical sample. For FCB, a real cut sample tells you more than any brochure — check edge integrity, density and finish.
  • Application fit. Cladding, flooring underlay, soffit and roofing are different products with different specs — match the board to the use.
  • The legal entity behind the brand. Ask which company name appears on the invoice and bill of lading, and check that name — not the brand — against the business register and shipment records.

Sources & data notes

Figures and company lists are indicative, from public reporting and trade-shipment databases for 2023–2024, and are provided for orientation only. The absence of a reliable national FCB capacity figure is itself the finding.

Correction (25 August 2026). An earlier version of this post listed Hiệp Phú and Vĩnh Tường as separate exporters; they are one company, and its Duraflex brand belongs to Saint-Gobain. That version also carried a supplier name we could not tie to any registered producer, which we have removed as a probable database mis-record. This is the exact failure mode the section above warns about — we ran into it in our own copy.
