The enquiry arrived at 11 pm our time, from a cabinet wholesaler in Ho Chi Minh City, and it was the question we hear most often in one form or another: “Your website lists melamine plywood, marine board, and faced OSB. I need 500 sheets for hotel furniture and shopfitting. Which one, and why?” He had been quoted three different boards by three different suppliers at three wildly different prices, and he suspected — correctly — that at least one of them was the wrong product for the job.
I work on the sales engineering side at BOYITE in Guigang, Guangxi, so let me answer the way I answered him, after asking what he was actually building.
Start with the job, not the price list
The three boards are not competitors; they are three different tools. Melamine plywood is a furniture board: a birch or eucalyptus core pressed with a decorative paper face, ready for cutting and edge-banding without any painting. If your factory makes wardrobes, desks, or shop display units, this is almost certainly the board you want, because it eliminates an entire finishing step. Our melamine line runs on MDI and water-based glues rated ENF, with formaldehyde release at or below 0.025 mg/m³ — a detail that matters when the furniture ends up in hotel rooms.
Marine board is a structure and moisture board. It exists for kitchens, bathrooms, formwork, boat interiors, and anywhere the panel will see water, steam, or tropical humidity. What makes it marine-grade is the adhesive — at our plant, a self-developed sticky-rice-based glue that holds through a 72-hour boil test — plus tighter core veneer selection. It costs more than standard plywood, and it is worth every cent of that premium exactly where melamine plywood would fail. If you want the full moisture story, we published a breakdown in our marine board waterproofing guide.
Faced OSB occupies the middle ground people forget about. The oriented strand core is pressed from whole wood strands with MDI adhesive, which makes it dimensionally very stable and, in our ENF configuration, extremely low in emissions. Add a melamine or veneer face and you get a panel that is cheaper than plywood at the same thickness, strong under load, and popular for packaging, flooring underlay, wall sheathing, and budget furniture frames. It is not the right face for a high-gloss retail display, and it is not a substitute for marine board in wet rooms — but for structural, hidden, or cost-driven applications it often beats both.
The comparison that actually decides it
Ask three questions. Will the panel be seen or hidden? Seen and touched daily, choose melamine plywood. Will it meet water or high humidity? Then marine board, whatever else is true. Is it structural or budget-driven? Faced OSB earns its place. After that, thickness and core matter more than the label: an 18 mm Eucalyptus-core melamine panel behaves very differently from a 15 mm poplar-core one, and honest suppliers quote by core species, not just by grade letter.
The Ho Chi Minh buyer ended up splitting his order — melamine plywood for the wardrobe carcasses, faced OSB for the drawer bottoms and back panels, marine board reserved for the bathroom vanities. His landed cost dropped about 9% against the single-board quotes, with no visible compromise.
