According to a recent report by Yole Group, China's Domestic Semiconductor Equipment Industry 2026, the localization rate of semiconductor equipment in China has risen from 8% in 2021 to 23.2% in 2025, and is projected to reach 39% by 2030. Nearly tripling in five years, equipment localization is entering an acceleration phase.
While the domestic substitution rate for equipment continues to climb, the localization of supporting consumables lags significantly behind. Chemical packaging drums, delivery pipelines, and other such components are also thresholds that must be crossed to achieve a self-reliant and controllable industrial chain.
01 High-End Consumables: An Underestimated Critical Link
When discussing semiconductor domestic substitution, most people immediately think of large-scale equipment such as lithography machines and etching machines. However, in actual production line operations, there is another category of supplies that is equally indispensable — ultra-high-purity packaging containers, especially Ultra-Clean HDPE (High-Density Polyethylene) Drums used for chemical delivery and storage.
Semiconductor manufacturing imposes extremely stringent purity requirements. Wet processing steps in wafer fabrication consume large quantities of electronic-grade chemicals — sulfuric acid, hydrogen peroxide, ammonia, hydrofluoric acid, and more. If the storage and transfer containers for these chemicals suffer from metal ion leaching, particle shedding, or organic contamination, it will directly increase wafer defect rates and reduce yield.
02 Technical Approach of BSL Ultra-Clean HDPE Drums
For a long time, the market share of high-end Ultra-Clean HDPE Drums has been dominated by a handful of foreign-funded enterprises. Against this industry backdrop, BSL (Baoshili) has achieved multiple technological breakthroughs in production processes and cleanliness control in response to the stringent requirements for packaging containers in semiconductor manufacturing, successfully developing 200L specification Ultra-Clean HDPE Drums.
Metal Ion Control
Sodium, potassium, iron, copper, nickel — metal ions commonly found in ordinary manufacturing processes are impurities that must be strictly controlled in semiconductor manufacturing. BSL Ultra-Clean HDPE Drums utilize high-purity HDPE raw materials and a proprietary blow molding process, controlling key metal ion content at the ppt (parts per trillion) level to meet the extreme impurity concentration requirements of advanced process nodes.
Particle Control
The smoothness of the drum's inner wall directly affects the risk of particle shedding. Conventional blow molding processes struggle to achieve micron-level surface smoothness standards. BSL has systematically optimized everything from mold design to molding parameters, ensuring uniformity and densification of the inner wall surface and significantly reducing the probability of particle shedding.
Production Stability Control
For wafer fabs, batch consistency matters more than single-point performance. BSL has established a comprehensive quality management system with traceable data at every stage — from raw material incoming inspection to finished product delivery — ensuring quality stability across batches.
SEMI Standard Certification
The semiconductor industry has an extremely high entry barrier. New materials and products must undergo lengthy validation cycles before entering wafer fab supply chains. BSL Ultra-Clean HDPE Drums have passed all relevant tests under SEMI standards. With an integrated solution capability of "product + service + certification," BSL has become a stable choice for semiconductor manufacturers.
From the accelerating doubling of equipment localization rates, to the 15th Five-Year Plan's explicit goal of "achieving decisive breakthroughs in key core technologies in priority areas such as integrated circuits across the entire chain," domestic substitution in the semiconductor industry is shifting from isolated breakthroughs to full-chain collaboration.
BSL has deep expertise in ultra-clean packaging and delivery. Ranging from Ultra-Clean PFA Tube to electronic-grade Ultra-Clean HDPE Drums, it has built a product system covering the entire "storage & transportation — delivery" chain of chemicals. As one of the few domestic enterprises capable of independently producing electronic-grade Ultra-Clean HDPE Drums, BSL's products are widely used in high-end manufacturing sectors including semiconductors, working with upstream and downstream industry chains to accelerate domestic substitution.
