Our global sourcing policies prohibit the use of child or prison labor in the production of material we sell. All vendors and suppliers are expected to comply with all applicable laws and regulations in the conduct of their business with Lowe's, and their products must meet regulatory and industry standards. Lowe's Code of Business Conduct and Ethics prohibits conflicts of interest in our dealings with vendors and holds vendors to conduct expectations similar to those of Lowe's employees.
With nearly 800 factories producing products for Lowe's, LGS ensures compliance with these standards with the help of operations in the United States, China, Hong Kong, Taiwan, Mexico and India. LGS uses internal and third-party Quality Assurance teams to help validate that our vendor partners operate safe and ethical factory environments that produce reliable and high-quality products.
In 2010, LGS performed more than 800 factory certifications and nearly 600 random social compliance audits. In addition, more than 17,000 product tests were conducted at independent third-party testing facilities, with many of our products pulled from production lines for testing during random production audits. LGS also inspects orders at facilities before approving them for shipping. In 2010, LGS conducted more than 12,000 pre-shipment inspections.
Driven to provide high-quality products produced by socially responsible vendors, we will continue to review our sourcing policies to ensure we continue to have the best practices in place.
