Dai Han Pharmaceutical primarily manufactures and sells basic pharmaceuticals used in hospitals and clinics, including IV infusion solutions, ampoule injections, and nutritional infusion products.
As of 2025, basic infusion solutions made up roughly 63% of sales, followed by other products at 17%, nutritional infusions at 13%, and ampoules/vials at 6%. The company also sells over-the-counter items such as contact lens solution and saline products to expand into the pharmacy retail channel.
More than 80% of supply goes to hospitals and clinics, built on a stable distribution network, and many of its products are designated as essential or anti-discontinuation medicines by the government, which places the company's focus on stable supply and quality rather than price competition.
Its production base consists of KGMP-certified facilities and automated production lines, complemented by a roughly 2,000-pyeong automated warehouse that improved inventory responsiveness and logistics efficiency.
The company holds a 5,000-pyeong site, of which the remaining 3,000 pyeong is earmarked for a new plant expansion, signaling preparation for medium- to long-term capacity growth.
In the infusion market, which has strong capital-intensive characteristics, equipment and process stability function as competitive advantages, and the company has repeatedly reinvested profits into production infrastructure rather than pursuing aggressive top-line expansion.
Since 2023, the company has operated under a sole CEO structure, with management focus centered on strengthening core competitiveness in its existing infusion and injection businesses rather than new business diversification.
