Health, Safety, and Labeling of Products

Hazardous Substance Management

In order to ensure that the company's products meet the standards of the “Restriction of the use of certain Hazardous Substances in Electrical and Electronic Equipment” (RoHS Directive) and achieve the goal of being free of hazardous substances, the "Restriction of Hazardous Substances Directive (RoHS) Management Measures" has been formulated to ensure All of SEEC products and manufacturing processes comply with international environmental protection laws and standards and meet international environmental protection requirements.

In addition, to effectively manage the Company’s self-manufactured product quality and production processes, SEEC implements strict controls at the source of production. In addition to requiring suppliers to sign the “Prohibited and Restricted Substances Compliance Guarantee,” the Company has established an “Incoming Material Inspection Procedure.” For the first delivery from a supplier, a test report issued by a third-party certification body verifying the absence of hazardous substances is required. Depending on quality management needs, suppliers may also be requested to provide updated thirdparty test reports on an irregular basis. Products that pass inspection are labeled as RoHS-compliant on the external packaging and noted as “RoHS Only” in the quality inspection record remarks column,ensuring that all supplied environmentally friendly materials and components comply with SEEC’s regulations on prohibited and restricted hazardous substances.

SEEC's banned and restricted substances are mainly the 10 hazardous substances specified in RoHS 2.0, and their types and concentrations must comply with the upper limits of the RoHS 2.0 regulations recently released by the EU. In 2024, all products produced by SEEC's business groups will comply with RoHS regulations, except for equipment with an operating voltage of less than 1000V AC or 1500V DC,such as heavy electrical products, which are within the scope of the RoHS Directive (2011/65/EU).

Although certain materials used in the Company’s products contain substances listed under IEC 62474 (such as lead, mercury, cadmium, and hexavalent chromium), their concentrations comply with relevant restriction standards. In addition, suppliers have provided self-declarations to ensure compliance with prohibited and restricted substance requirements. In 2024, none of Shihlin Electric’s sold products contained substances that required active disclosure under the IEC 62474 standard, and the revenue generated from such products accounted for 0% of the total revenue.

Product Safety and Labeling

The products have passed relevant tests and verifications such as international, national and customer standards before leaving the factory, and are 100% compliant with safety regulations. The products of the Heavy Electric Business Group exported to North America and the Automobile Equipment Business Group are 100% compliant with UL regulations. The electromagnetic contactors for export of the Breaker & Switchgear Business Group have obtained UL certification. The SDE series, SDP-A, SDC-A, and SDC-E series of servo drives of the Automation Business Group have all obtained UL certification. In addition, "Safety Precautions" are marked on the product manual when shipped to provide consumers with safe usage, installation environment and other product safety information.

The quality of the products of SEEC conforms to customer specifications or national standards CNS or well-known international standards (such as IEC, IEEE...). Taking CNS compliance as an example,through certification practices such as CNS Mark certification, we will continue to ensure customer safety in use. In conjunction with the promotion of the new version of the quality management system,we will continue to maintain and obtain the updated version of the CNS Mark certificate, and control product safety and labeling with the spirit of CNS Mark certification. As of 2024, an excerpt of the company’s CNS Mark certification items is as follows:

The cumulative statistical certificate cases for heavy electrical products, low-voltage switches and industrial control products (sent to impartial testing agencies for testing and passing the test) are as follows:

Customer Consultation Process

Each business group has sales technicians in each branch, who can go to the customer site immediately to identify and eliminate issues. Once the customer issue is identified, it will be transferred to the dedicated department for analysis and processing. After the issue is solved, we will also track customer's subsequent usage status. This business group retains various problem-solving databases, conducts regular reviews and internal education and training on relevant issues, and continues to improve the efficiency of customer problem-solving.

Product Recall and Remediation Mechanism

The products manufactured and produced by SEEC strictly abide by relevant regulations and customer contract specifications, and we produce products that meet international standards, national standards and customer requirements. In 2024, SEEC had no product recalls, nor any legal proceedings or monetary losses due to violations of product safety regulations.

In addition, the company has established "Quality Service and Complaint Handling Procedures". When receiving customer complaints, the company will implement the following in accordance with operating procedures and management regulations:

1. Provide plans for product and service quality enhancement to prevent complaints.

2. When complaints occur, information can be conveyed and dealt with promptly.

3. Confirm customer satisfaction and prevent similar complaints from happening again.

The main contact window for customer complaints is the business unit. If it is a product quality problem, the quality assurance center will mainly conduct analysis, countermeasures and statistics on the returned products and then reply to the customer. If the complaint involves product safety liability, a meeting will be conducted to handle the case.

Customer Satisfaction

Each business unit regularly conducts customer satisfaction surveys every year, focus on four indicators: quality, delivery time, price, and service;and then prepare a "Customer Satisfaction Survey Form" and submit it to the top management of the business group. If the survey results are lower than 3 points (full score is 5 points), a review will be conducted for further enhancement.

Overall, the overall satisfaction of SEEC has maintained a certain level, and the average score has remained above 4 points. In 2024, the average total customer satisfaction score of each business group was 4.5 points. The overall service satisfaction has increased compared with last year, and the scores of other indicators have also reached a satisfactory level. Based on the evaluation of customer satisfaction factors, we will organize, analyze and feedback to understand customers' ideas and make relevant improvements to improve service quality.
