The Single-use Assemblies Market is experiencing increasing demand from contract manufacturing organizations as pharmaceutical and biotechnology companies outsource more production activities. The market is forecast to reach USD 27.55 billion by 2035 from USD 1.98 billion in 2025, expanding at a 30.1% CAGR.

CMOs and CROs are becoming important buyers because their facilities often need to support multiple products, clients, and production campaigns. Flexible single-use systems can complement this operating model by allowing manufacturing environments to adapt more readily to changing production requirements.

The report identifies CMOs and CROs as the fastest-growing end-user category, with a projected 32.0% CAGR between 2026 and 2035. This growth is closely connected with the expansion of outsourced biomanufacturing and the increasing number of specialized biologic and advanced-therapy programs.

Bag assemblies are expected to be another major growth engine, with a projected 31.5% CAGR. Their use across storage, buffer preparation, media handling, and other processes is expanding the addressable market for disposable systems. Filtration assemblies remain the largest product category, holding 29.9% of market share in 2025.

Asia-Pacific presents particularly strong opportunities for suppliers serving outsourced manufacturing operations. The region is forecast to record a 31.6% CAGR through 2035, supported by expanding biopharmaceutical infrastructure and increasing investment in regional production capacity.
