Millennium Group International Holdings is a paper-based packaging manufacturer headquartered in Hong Kong, with production facilities in Shenzhen, China and Vietnam. The company makes two core product types: printed paper boxes (inner packaging) used by consumer brands for retail-facing product packaging, and corrugated cardboard boxes (outer packaging) used for shipping and storage. Millennium positions itself as a "one-stop" supplier, bundling design, material sourcing, production, testing, and logistics into a single price rather than charging separately for each service. Customers are primarily brand owners and trading companies in Asia, with deliveries reaching China, Hong Kong, Vietnam, Australia, the U.S., and Germany. The business is largely made-to-order, with production planned around confirmed purchase orders. Beyond manufacturing, Millennium operates a supply chain management business through its MPG Group, helping global brands source packaging from Vietnam and other ASEAN suppliers. The company is winding down its legacy corrugated subsidiary in Shenzhen and consolidating that production into its main facility. A new Vietnam factory launched in July 2025, reflecting a deliberate shift in manufacturing footprint as global brands diversify supply chains away from China. Key profitability drivers include paper input costs, production utilization across highly automated lines, and customer concentration — the largest single customer accounted for roughly 20% of revenue in FY25. The Shenzhen subsidiary holds High-tech Enterprise status, entitling it to a preferential 15% corporate income tax rate, contingent on maintaining R&D spending above 3% of annual revenue.
