The document discusses the chain of derived demand for plywood. Plywood relies on inputs from the wood cutting, processed wood, adhesive, chemical, and machinery industries. It is then used downstream in industries like furniture, electronics, marine, transportation, commercial vehicles, education, and more. Finally, it reaches end consumers for uses like interior decoration, matchsticks, and more. Key competitors for plywood include industries using alternative materials like polyvinyl carbonate, recycled products, aluminum, wax, fiberglass, and bamboo.
