Buyers specify thickness, face, and glue class — then accept whatever sits in the core. Yet the core species sets a plywood panel's density, and density drives its weight, stiffness, screw-hold, and even how many sheets fit in a shipping container. This episode is a procurement-focused guide to the four plantation-grown cores behind most Vietnamese plywood — acacia, eucalyptus, rubberwood (hevea), and styrax — and how to match the core to the job instead of trusting the vague label "hardwood plywood."

What You'll Learn

• The core-density ladder as planning figures: styrax ~500, acacia ~580, eucalyptus ~650, rubberwood ~700 kg/m³ — and why the mill certificate, not the species name, governs any batch.
• Why acacia is the workhorse core, and where eucalyptus and rubberwood earn their extra mass in stiffness and screw-hold.
• What "full white core" styrax is for — and why it is not birch plywood.
• How core weight becomes a freight cost when a container reaches its payload limit before it is physically full.
• Why each of these cores is plantation-grown, and what FSC/PEFC and EUDR mean for European buyers of rubberwood.

Key Standards & Data Discussed

• Planning densities (~500 / 580 / 650 / 700 kg/m³) confirmed on the mill certificate per batch; species named botanically — Styrax tonkinensis, the Acacia hybrid, Eucalyptus urophylla/camaldulensis, and Hevea brasiliensis.
• Sustainability and traceability: plantation-grown sourcing, FSC/PEFC chain-of-custody, and rubberwood now within EU Deforestation Regulation (EUDR) scope.
• Vinawood's panels are manufactured to meet the relevant standards and, depending on grade and market, can carry FSC chain-of-custody, EPA TSCA Title VI (CARB Phase 2), and CE marking under EN 13986 (certification status current at time of production; verify with current supplier documentation before procurement).
