Universal Scientific Industrial

In accordance with international regulations, customer requirements and environmental protection trends, Company conducts comprehensive, systematic, and transparent management and control of product design, material procurement, product manufacturing, transportation, packaging, sales and recycling every year to achieve the reduction and exemption of hazardous substances free (HSF) goal. And formulated our “Green Products Policy and Design Principles” to guide the development of environmentally responsible products. The Company is committed to developing products with lower pollution, reduced resource consumption, and lower carbon emissions, while providing customers with enhanced product design and manufacturing services. For related investments and performance achievements, please refer to the “Sustainable Product or Service Investments.”

We follow the IECQ QC 080000 Hazardous Substance Process Management System Standard and establish comprehensive control procedures for green parts and materials to ensure compliance with international regulations and customer requirements regarding restricted hazardous substances. USI’s suppliers must confirm all provided components, non-BOM and packaging materials comply with applicable regulatory requirements and substance control standards. Suppliers are required to submit relevant compliance information through the “Green Product Assurance Reporting System (GPARS)” or Questionnaire methods. For detailed management requirements, please refer to the “Hazardous Substance Management” and “Partial Selection of Restricted Environmentally Hazardous Substances Contained in Products.”

Hazardous Substance Risk Assessment Process

USI's Hazardous Substance Risk Assessment Process includes the management of hazardous substances in products and chemicals used in production. We evaluate hazardous substance risks and opportunities based on frequency of occurrence, frequency of exposure, and degree/severity of impact, and the higher the risk multiplier score, the higher the risk level. The Company uses the risk level identification to propose countermeasures to reduce the potential impacts on human health and the environment.

Risk Assessment Process

Note:
1. Dose-response assessment include the human health hazard, physicochemical hazard, environmental hazard, persistent, bioaccumulative and toxic (PBT) and very persistent and very bioaccumulative (vPvB).
2. Define scope include the material manufacturing, use and exposure information.
3. Setting exposure scenario include the used scope, usage, possible exposure routes and exposure control measures.
4. Estimate exposure include the worker exposure/concentration or environmental exposure concentration.

Chemical Safety Management Process

To mitigate potential safety and environmental risks arising from the use of chemicals, USI has established a comprehensive Chemical Control List that defines substances prohibited from use within its operations. By implementing rigorous upstream chemical management and source control measures, USI proactively reduces chemical-related risks and reinforces its commitment to workplace safety, environmental protection, and regulatory compliance.

USIs R&D personnel have ecological design capabilities and continues to implement green concepts and clean technology into their projects, which allows us to sell environmentally friendly products around the world.

Promoting Green Design

A green product with clean technology needs to comply with two or more green products ecological design standards to improve energy efficiency and reduce environmental pollution. In 2025, revenue from cleaning-related technologies accounted for 55.71% of the overall revenue of the Company. In the future, we will continue to invest in green product research and development and increase the proportion of green products.

The following is the individual performance of ecological design products over the years:

Product Revenue Ratio	2022	2023	2024	2025
Energy Efficiency	11.2%	2.5%	2.5%	2.0%
Electronic Waste Recycling	13.2%	11.9%	9.7%	11.8%
Light and Compact	58.0%	67.0%	67.8%	67.1%
The Proportion of Total Revenue	82.4%	81.4%	80.0%	80.9%

In our product energy saving evaluation, USI's eco-design products saved 58.7 GWh (about 211,353 GJ), equivalent to reducing 23,716 metric tonnes of CO₂.

We encourage a green and innovative corporate culture and facilitate green design proposals. USI's green products were designed based on its green product design principles and green promise, the results of green-related design are as follows:

Product Compliance Aspect

We stringently control the use of raw materials for our products and use low-pollution and non-toxic raw materials to ensure that our products comply with the relevant regulations and directives. Furthermore, we conduct product lifecycle inventory and eco-design evaluations, and publish product eco-characteristics manual to comply with the EU ErP Directives.

To protect users, all facilities apply the Factory Inspection Mechanism to ensure product safety and compliance with relevant laws, regulations, and ordinances internationally and where they are sold. In 2025, we received zero complaints about products endangering human health and safety, and no product safety-related violations were found.

Eco Labels Aspect

SDG 12, Responsible Consumption and Production, calls on countries and industries to promote circular economy models by optimizing material use and enhancing resource circulation. This approach encourages green product design focused on durability, repairability, and recyclability, enabling resources to remain within a closed-loop supply chain and maximizing their value throughout the product lifecycle. By incorporating life cycle assessment (LCA) principles and advancing green economic development, organizations can contribute to more sustainable patterns of consumption and production.

Eco-labels help consumers identify products and services that demonstrate environmental performance beyond regulatory requirements. As such, eco-labeling is recognized as one of the effective approaches to supporting circular economy practices and promoting sustainable consumption.

Product Eco Labels Performance

Investigate the carbon emissions of products from raw material acquisition, manufacturing, use and disposal in a life cycle manner, and converted into the sum of carbon dioxide equivalents.

Since 2017, USI has continued to review the carbon footprint data of a major product every year and verified it through a third-party or self-inventory to disclose the performance of greenhouse gas reduction, and further identify the key factors of carbon emissions through the report results to achieve the reduction purpose.
