What certifications are required for products to be exported to the U.S.?

Today's U.S., buyers generally require products to obtain UL certification, not that they are superstitious about the prestige of UL. In fact, they have no choice but to do so, only the UL mark of the product can successfully buy product insurance, only the UL mark of the product can be accepted by most retailers, only the UL mark of the product in the quality of the accident may be able to escape product liability ....... All these led to the application of UL by the merchants, and the actions of the merchants for more than a hundred years led to more monopoly of UL! --------------------------------------------- UL is the abbreviation of Underwriter Laboratories Inc. UL Safety Testing Institute is the most authoritative in the U.S., and is also the world's largest private organization engaged in safety testing and certification. It is an independent, non-profit, for the public **** safety test professional organizations. It uses scientific testing methods to study and determine a variety of materials, devices, products, equipment, buildings, etc. on life, property and the degree of harm; to determine, write, issue the corresponding standards and help reduce and prevent the loss of life and property caused by the information, while carrying out factual research business. In short, it is mainly engaged in product safety certification and business safety certificate business, and its ultimate goal is to contribute to the market to get the goods with a considerable safety level and to ensure the safety of human health and property. Product safety certification as an effective means of eliminating technical barriers to international trade, UL to promote the development of international trade also plays a positive role. UL standard is a continuous improvement of the document. UL standard revision request is made by industry, users, UL engineers or other interested parties. Industry revision process: When it is necessary to modify certain elements of a UL Standard, the requirements for the product will change accordingly, and for this reason, UL has established a formal industry revision process. The effective date of each changed section of a UL Standard is announced at the time of publication. The effective date, the relevant products belonging to the UL tracking and inspection services must be in accordance with the new requirements of the changes, so that from the date of the standard change to the effective date of the publication of a sufficient period of time to allow factories to change their products and resubmitted to UL testing. Once the change request has been formally adopted, the industry amendment process is implemented. This procedure includes sending formal notification to the applicant, the start date of the change, and having a UL engineer help the applicant check the parts of the product that need to be changed in the same way that he or she would qualify the product, as well as revising the UL factory tracking inspection documentation before the effective date. After the effective date of the new standard, UL inspection representatives will visit the manufacturer, according to the revised requirements to review the corresponding changes in the part. UL product certification of the three main services: 1. Listing applies mainly to the whole product, is a formal product certification, and published in the UL product catalog certified products. 2. 2. Recognition Mainly used for components. Sometimes it is not even necessary to test the product to obtain recognition. Note that UL does not always recognize UL Recognized Components (e.g., certain UL Recognized Switches, Fuse) when certifying the entire product. 3. Classification UL is the oldest certification company in the world, and perhaps the richest in the world, and is a privately held company founded in 1894. The UL standard, and most of their own standards and the American National Standards ANSI is not the same, and the International Electrotechnical Commission IEC standards, simply unrelated. Very similar to UL's current position in the U.S. is the well-known computer software giant "Microsoft". It is also a private company, but in fact manipulate the world's computer operating system industry standards, excessive monopoly to the development of the industry's negative impact can not be ignored. UL is in sharp contrast to the vibrant European certification bodies, they join together to develop a unified safety standards (EN standards), mutual recognition, mutual supervision, under the banner of the IEC, and even with the formation of a unified front around the world, including China, the vast majority of the world's countries, except for North America have to rely on the European manipulation of the IEC system. Most people's eyes inside the UL represents the U.S. national product safety standards, in fact, the U.S. national standards body is the American National Standards Institute ANSI (American National Standards Institute), rather than UL. It is worth mentioning that the United States has up to dozens of electrical standards organizations, although not as prominent as the UL, in many industries play an important role. play an important role in many industries. UL's success depends on America's free system and its unique federalism. The United States does not officially have an authoritarian standards body (such as China's Electrotechnical Commission). This has led to an opportunity for certification bodies to outperform national standards bodies, and as a result UL has made a name for itself. U.S. federal authorities do not have any mandatory certification requirements for electrical products, and recognizes most of the certification bodies, including UL, ETL, NRTL and so on. However, some state governments are mandatory product certification, and may not recognize all the federal government has recognized the certification body, which led to many certification bodies can not form a monopoly with the UL company Fairplay. Today's U.S., buyers are generally required to obtain UL certification of the product, not that they are superstitious about the prestige of UL. In fact, they have no choice but to buy product insurance, only the UL mark of the product can be successfully, only the UL mark of the product can be accepted by most retailers, only the UL mark of the product in the event of quality accidents may be able to escape product liability ....... All of this has led to the application of UL, and the actions of the merchants for more than 100 years have led to a greater monopoly of UL! UL standard is UL's own development, different products have different standards, so UL's standards are so many that even UL engineers themselves can not count. UL standards published by UL alone, "Standard Catalog" has a thick book. And UL standards are changed very frequently. Compared with the IEC classification standards, UL in this regard is simply an elementary school student. Application for the UL Mark Any individual, factory, or company can apply for the UL Mark. Any individual, factory, or company can apply for a UL Mark. Simply contact UL, mail or fax the product information to UL, and receive an official application form from UL. Look carefully at the application form and valuation sheet printed by UL engineers, sign your name and mail it back to UL to indicate the formal application. Send dollars and samples, UL engineers will start testing and keep in touch with you. But it is very difficult to send dollars from China to the United States. So at least 90% of the UL certificates applied for in China are applied for informally or illegally by sending money to pay bills. For general product applications, please contact Camas Laboratories, which specializes in the Chinese market. Although UL has two offices in Shanghai and Guangzhou***, they do not accept product certification applications.
