According to the relevant regulations, the Korean Customs prohibits the entry of the batch of LED lights and requires the goods to be returned or destroyed. The production enterprises can only do the return processing, resulting in a large economic loss. Recently, two batches of LED lamps exported to South Korea from Ningbo Daxie Development Zone Weiheng Lighting Appliance Co., Ltd. were returned, with a value of 11,640 and 20,100, respectively, amounting to 32,592 and 43,559 US dollars respectively. The Otsuka Inspection and Quarantine Bureau found that the two batches of goods were returned because the quality of the products did not meet the standard requirements, that is, failed to pass the electromagnetic compatibility (EMC) quality standards. According to the relevant regulations, the Korean Customs prohibits the entry of the batch of LED lights and requires the goods to be returned or destroyed. The production enterprises can only do the return processing, resulting in a large economic loss. EMC is the ability of a device or system to operate in its electromagnetic environment and to produce unacceptable electromagnetic interference to any device in its environment. EMC includes two requirements: on the one hand, the electromagnetic interference generated by the equipment in the normal operation process cannot exceed a certain limit; on the other hand, the appliance has a certain degree of electromagnetic interference existing in the environment. Immunity, ie electromagnetic sensitivity. The EMC test consists of an electromagnetic emission (EMI) test item and an electromagnetic anti-infection (EMS) test item. The EMC test standards for LED lamps are mainly CISPR 15 (EN 55015), EN 61547, EN61000-3-2, EN61000-3-3, IEC62560, IEC 62031, etc. The detected items are roughly disturbance voltage, radiation battery disturbance, insertion loss, electrostatic discharge, RF electromagnetic field, power frequency magnetic field, electrical fast transient pulse group, injection current, surge, voltage dip and short-term interruption, harmonic current, The voltage fluctuations flash and so on. At present, the requirements of the EMC regulations for LED lamps vary from country to country, and there are differences. Among them, the EU is mainly based on EN55015 and EN61000-3-2/3, and EMS is mainly EN61547. In the United States, FCC Part 18 is required. The limit is different from EN55015 and EN55022, but it can comply with FCC Part 18 in accordance with EN55022. Korean technical standards are equivalent to CISPR15, IEC61000, etc. In response to the reasons for the return and the problems found in the investigation, the Daxie Bureau urged the enterprise to carry out rectification and remediation in a timely manner. The LED lamps available in the two batches of returns are intended to be used by domestic buyers to reduce the economic losses caused by the return. The other models are not suitable for domestic use. LED lamps used by customers are dismantled and destroyed. In 2016, the scale of LED-related industries based on lighting in Ningbo has reached 40 billion yuan, a year-on-year increase of 30%, and formed a relatively complete industrial chain. Ningbo has become the most important production and export base for semiconductor lighting products in the country. At the same time, however, due to various factors such as the impact of foreign technical trade measures and quality defects, the export lamps have been reported to the foreign market for return shipments and recalls. Not only will the company suffer economic losses, it may also increase the proportion of spot checks on imported products by importing countries and reduce the international reputation of Chinese products. The risk of returning the exported lamps cannot be ignored. The LED lamp is a non-statutory inspection product and lacks the inspection and inspection of the inspection and quarantine department. The retrospective investigation of export repatriation is an important starting point for inspection and quarantine to play a functional role, improve the quality of enterprise products, and better serve the healthy development of foreign trade economy. The Otsuka Bureau strengthens the retrospective investigation of export product return shipments through measures such as return shipment information collection, cause investigation, risk research and judgment, and actively exerts the advantages of policies, technologies, talents and information to find the shortcomings in the production and export links. Help enterprises to solve technical problems and enhance the awareness of product quality and trade risk. The Daxie Bureau also combines the investigation of return shipments to provide information services to enterprises and guide enterprises to actively carry out certification work for export products in the process of production and export in the future. Always pay attention to the international certification of export products, and do the corresponding product certification for different countries and regions. For example, KC certification is required for exporting Korean LED products, FCC certification is required for export to the United States, and differences should be made if CB certification is obtained. Test the certification and transformation work, improve the product quality level through product certification to meet the product quality requirements of the importing country. The second is to always control the quality control of production quality management. As the main body of quality responsibility, export enterprises should strengthen the daily control of product quality and do a good job in product testing. We can rely on third-party testing agencies to do quality testing and testing of export products. According to the export country's product standards, the export products are tested in a targeted manner, and problems are found to be solved in time to ensure that the exported products meet the standards and requirements of the importing country. The third is to take the initiative to study and study the quality standards of lamps in the international market. Enterprises should strengthen and inspect the quarantine, industry associations and other departments to communicate, establish a joint response mechanism, share relevant technical trade measures and trade policies of LED lighting products. It is necessary to improve the collection, knowledge and mastery of the latest foreign laws, quality standards, trade rules, etc., and keep track of the latest developments in relevant policies and regulations for export products, so as to get involved in advance and respond actively, and continuously improve product technology and quality production in line with the market. The required products effectively avoid export repatriation and expand the popularity and market share of products in foreign markets. Text: Ma Sijie Zhang Yiqun Hu Ming "China National Times"
