Tariff Storm Hits: Saining Domestic Alternatives Safeguard Scientific Research

In April 2025, China–US trade tensions escalated sharply, entering a phase of intense tariff confrontation.

On April 3, the United States announced a 34% “reciprocal tariff” on Chinese goods. In response, China imposed a 34% tariff on all imports originating from the United States.

On April 8, the US government further increased the tariff rate on Chinese exports to 84%.

On April 9, China quickly issued a notice raising tariffs on US imports from 34% to 84%, effective from 12:01 PM on April 10.

Breaking Through Barriers, Stabilizing Scientific Research

This round of tariff escalation has had a significant impact on the life sciences industry. The cost of imported reagents and consumables has surged, logistics cycles have been extended, and supply chain stability is under pressure, placing increasing financial strain on research institutions and enterprises.

The ongoing tariff conflict has disrupted global supply chains, with the life sciences sector among the first to be affected. Prices for imported high-end biological consumables may rise significantly.

Against this backdrop, Saining Biotech, leveraging independent innovation and localized supply advantages, provides researchers with a reliable domestic alternative pathway, ensuring stable scientific research even under tariff volatility.

01 Independent Innovation, Breaking Technical Barriers

Breakthroughs in High-End Consumables R&D

As an emerging player in China’s biotechnology sector, Saining Biotech focuses on the localization of high-end laboratory consumables. Driven by technological innovation, the company has achieved domestic substitution of key high-end products through early strategic R&D planning.

Its self-developed products—including Matrigel-coated inserts, ultra-low attachment coatings, cell chambers, chamber slides, and confocal culture dishes—have reached internationally advanced performance standards, with some parameters even surpassing imported brands.

1. Matrigel-Coated Cell Chamber Series

Matrigel-coated cell chambers are core consumables used in tumor invasion assays, angiogenesis studies, and organoid culture. Their technological evolution has been closely tied to European and American companies.

Imported brands, relying on mouse sarcoma-derived basement membrane matrix and standardized coating processes, have long dominated over 90% of the global market. These products precisely regulate laminin, type IV collagen, and other components, becoming the “gold standard” for cell invasion assays. However, they are expensive—typically 3,000–5,000 RMB per batch—and pose risks such as animal-derived contamination and unstable supply chains.

Saining Biotech focuses on foundational tools for cell function research. Its independently developed Matrigel-coated chamber series matches imported performance standards and now covers all specifications of cell chambers.

2. 96-Well High-Throughput (HTS) Cell Chamber

The 96-well high-throughput cell chamber is a key tool for cell migration, drug screening, and co-culture studies. Since the 1990s, international biotech giants have dominated this field using polycarbonate (PC) and polyester (PET) membranes, automated compatibility designs, and anti-leak structures.

Due to technical barriers and patent restrictions, domestic users have long relied on imports, facing high costs and unstable supply chains.

Imported 96-well HTS chambers can cost 2,000–5,000 RMB per plate. Saining reduces costs by more than 50%, significantly lowering research expenses while eliminating supply chain risks caused by international logistics.

3. Ultra-Low Attachment Coated Culture Series

Ultra-low attachment technology is a core tool for 3D cell culture, organoid research, and tumor spheroid formation. It has long been dominated by global leaders using hydrogel-based coatings, hydrophilic neutral surfaces, and anti-protein adhesion technologies.

This technology was once listed among the “35 bottleneck technologies.”

Saining’s breakthrough enables China to move from “following” to “running alongside” global leaders, reducing dependence on international supply chains. The product line now includes culture plates, dishes, and flasks.

4. Cell Chamber Series

Cell chambers are essential consumables for migration, invasion, and co-culture experiments and have long been dominated by Western companies, holding over 90% of the global market.

Their technical barriers include precision membrane manufacturing, surface treatment processes, and patent protection.

In 2024, Saining launched its first domestic cell chamber series covering 6-well, 12-well, and 24-well formats with both PC and PET membranes.

The PC membrane offers lower adsorption, while PET provides higher optical clarity. The membrane types and pore density have reached or exceeded imported brands, marking a shift from “following” to “matching.” The product has become a top-selling domestic category.

5. Chamber Slides & Confocal Culture Dishes

High-end laboratory consumables such as chamber slides and confocal culture dishes have long been monopolized by international brands.

Imported products rely on high-precision glass bottoms, medical-grade adhesive bonding, and sterile tissue culture treatment, making them essential for confocal microscopy and live-cell imaging.

Saining’s domestically developed products fill this gap, with performance reaching or exceeding imported standards. Available specifications include 15 mm, 20 mm glass bottoms, 35 mm and 39 mm formats, quadrant designs, and black versions. Sterile blister packaging reduces contamination risks.

Full Replacement Capability: Covering Global Brands

Saining Biotech has built a portfolio of over 3,000 SKUs covering cell culture, molecular testing, liquid handling, sample storage, and biosafety protection.

It provides full-category substitution for imported brands, with terminal prices only 30%–40% of imported equivalents.

1. Cell Culture Series

Cell culture is a critical process in life science research.

Saining provides culture plates, dishes, flasks, and cell chambers designed to ensure a stable in vitro environment, supporting reliable experimental performance across diverse research needs.

2. Biological Testing Series

Products include PCR tubes, PCR plates, enzyme-linked plates, and deep-well plates, accelerating molecular biology research.

Filtration consumables such as syringe filters, vacuum filters, and ultrafiltration tubes improve sample processing efficiency.

Microbiology consumables—including petri dishes, inoculation loops, and spreaders—support microbial detection in pharmaceuticals, cosmetics, food, and beverage industries.

3. Liquid Handling Series

Liquid handling consumables are designed for precision and ease of use, supporting global scientific workflows.

Products include pipette tips, serological pipettes, Pasteur pipettes, and reagent reservoirs.

Saining centrifuge tubes undergo rigorous pressure testing beyond standard specifications, ensuring accuracy in scale markings, wall thickness, concentricity, clarity, and sealing performance.

4. Sample Storage Series

Cryogenic storage is widely used for long-term preservation of biological samples and cells.

Saining cryotubes are made from USP Class VI certified medical-grade polypropylene, available in multiple volumes and cap colors for low-temperature storage.
