Is Diseconomies of scale a barriers to entry?

Diseconomies of scale are not typically considered a barrier to entry; rather, they refer to the inefficiencies that can occur when a company grows too large and its per-unit costs start to increase. Barriers to entry are obstacles that make it difficult for new competitors to enter a market, such as high startup costs or regulatory requirements. While diseconomies of scale can affect existing firms' competitiveness, they do not directly prevent new entrants from entering a market.
