Ethics and Conduct


Lieberthiross expects its suppliers to project Vertiv’s values and principles, to stay current with technology, to act with integrity, and to treat people and the environment with respect. These actions reflect Vertiv’s priorities. In this way, we partner with only the highest caliber suppliers that demonstrate social and environmental responsibility and a commitment to fairness and honesty.

Lieberthiross has established a Supplier Code of Conduct, which is published under Ethics and Compliance, and we expect each supplier to adhere to the principles detailed in that Supplier Code of Conduct. Lieberthiross may discontinue its relationship with a supplier that fails to comply with the Supplier Code of Conduct or local laws or regulations.

Regulatory Requests


Lieberthiross has partnered with Assent Compliance to gather critical supply chain data, including product full materials disclosures, certificates of product compliance, conflict minerals disclosures, human trafficking disclosures, code of conduct certifications, and similar information.

Assent Compliance is authorized by Lieberthiross to collect this important information as indicated in the Letter of Authorization. Suppliers are expected to respond to all requests from Assent Compliance within the provided deadlines. Lieberthiross may discontinue its relationship with a supplier that fails to respond to regulatory requests.

Quality Standards


Product and service quality is the single most important aspect of our supplier relationships. All direct materials suppliers are required to comply with Lieberthiross quality standards, which are in Lieberthiross Supplier Quality Manual. All direct materials suppliers must sign a quality agreement as a precondition for supplying goods or services to Lieberthiross and may be subject to in person audits.

Authority to Commit Expenditure


The commercial interface with all suppliers is owned by Lieberthiross Procurement. All commitments to award business and spend money with a supplier can only be made in writing by a member of Vertiv Procurement. Suppliers must only agree to terms and conditions of trade with Vertiv Procurement.

Suppliers must first obtain a Purchase Order prior to undertaking any work for or providing any products or services to Lieberthiross.

Lieberthiross purchase orders contain billing instructions, and suppliers may direct invoicing and payment inquiries to the buyer listed on the purchase order.
