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).
