Welcome to CSCL Services foreign UL MACHINE CERTIFICATION

---

Both UL (Underwriters Laboratories) and CE (Conformité Européenne) are marks of product conformity, but they have significant differences in their purpose, authority, and application. Understanding these differences is crucial for manufacturers and consumers, particularly for products intended for the North American and European markets.

• Purpose and Origin:
  
  • UL: UL is a global, independent safety science company that provides product testing, inspection, and certification services. Its primary mission is to promote safe working and living environments. A UL mark signifies that a product has been tested by UL and meets specific, rigorous safety standards, primarily for the United States and Canada.
    
  • CE: CE is a marking that indicates a product's compliance with applicable European Union (EU) directives regarding safety, health, and environmental protection. It is essentially a "passport" that allows products to be sold freely within the European Economic Area (EEA). The CE mark is a declaration by the manufacturer, not a third-party certification.
    
• Mandatory vs. Voluntary:
  
  • UL: UL certification is generally voluntary. However, in practice, many local and state building codes in the U.S. and Canada require products to be certified by a Nationally Recognized Testing Laboratory (NRTL), and UL is the most well-known of these. For many products, particularly those used in construction or electrical installations, a UL mark is a de facto requirement to gain market acceptance.
    
  • CE: The CE mark is mandatory for all products that fall under one of the "New Approach" directives and are intended to be sold in the EEA, regardless of where they were manufactured. Without a CE mark, a product cannot be legally placed on the market in Europe.
    
• Certification Process:
  
  • UL: The UL certification process is a third-party system. A manufacturer must submit product samples to UL for testing and evaluation against its published safety standards. If the product passes, UL issues a certification. UL also conducts regular, unannounced factory inspections to ensure the manufacturer's products continue to meet the standards.
    
  • CE: The CE mark is primarily a self-declaration system. The manufacturer is responsible for ensuring their product conforms to all relevant EU directives and harmonized standards. They must create and maintain a "technical file" that documents this conformity and issue a Declaration of Conformity. For some high-risk products, a "Notified Body" (an independent third-party organization authorized by the EU) must be involved in the assessment.
    
• Scope and Recognition:
  
  • UL: The UL mark is specifically recognized and respected in the United States and Canada. While it is a global company, its certification marks are not automatically accepted in the European market. A UL-certified product would still need to meet European standards to be sold in the EEA.
    
  • CE: The CE mark is only valid within the EEA. It has no legal standing in the United States or Canada. A CE-marked product sold in North America must also meet local and national requirements, which often involve certification by a recognized NRTL like UL.
