The Wärtsilä Supplier Handbook provides a general overview of Wärtsilä’s expectations of its suppliers:
The handbook is applicable both for existing Wärtsilä suppliers as well as for companies desiring to become suppliers. It is intended to provide guidance as to how to build supplier operations that meet our company requirements. It also clarifies requirements regarding Wärtsilä’s environmental and sustainability strategy, as well as ethical business and Code of Conduct.
The handbook does not overrule any signed agreements, project specific documentation, purchase orders, drawings, specifications, and/or instructions applied to specific products in detail.
The Supplier Requirements mentioned in the Supplier Handbook are subject to change. The latest Supplier Requirements which are applicable to all suppliers of Wärtsilä are mentioned on the Supplier Requirements page.
The Safety Handbook offers assistance and guidance for performing work safely, at Wärtsilä project sites, in factories or workshops, or in the offices. This Handbook provides a quick guide and summary of the minimum, basic safety practices to be applied worldwide by Wärtsilä personnel, without overriding any local additional rules and regulations. Local regulation should always apply in addition to these corporate guidelines.
The cyber security brochure shares some of the behaviours which Wärtsilä recognises as best practices. In the brochure you can find guidelines which support a common and shared responsibility in ensuring the cyber security of the ecosystem for both Wärtsilä and our partners.
Ten life-saving rules are put in place to ensure consistent behavior to prevent incidents that could result in a serious injury or a fatality. The life-saving rules apply to all workers and partners involved with Wärtsilä’s operations or visiting our premises.
Wärtsilä prefers e-invoices, please find more information on the Digital Collaboration page. If an e-invoice is not applicable in your country, please follow the instructions mentioned on the purchase order. Wärtsilä does not retrieve purchase invoices from external sources, e.g. customer portals.
Wärtsilä requires its approved suppliers to give advance notice of future changes to banking information. If the change request is not submitted to Wärtsilä on time and to a correct contact, Wärtsilä cannot pay the invoices until the bank details are confirmed by supplier.
When new suppliers are onboarded, Wärtsilä intends to start collecting bank account information already during the general sourcing process and finalize it at the latest when signing the procurement contract, to make it possible to start transactions soonest after contracting. Wärtsilä will contact supplier with separate instructions for the detail’s collections.
The required information is stated in the Purchase Order that Wärtsilä has issued to you. Please help us ensure smooth invoice processing by providing all needed content information in your invoice. Use the checklist below before sending your invoice to Wärtsilä.
NOTE! Purchase invoices must comply with Wärtsilä purchase invoice requirements. Failure to do so will result in delayed payments.
