Purchasing Organisation & Conditions

Wilo Purchasing Organisation

Per year 3,000 t stainless steel, 4,000 t copper wire, 12,000 t sheet steel, 13,000 t cast parts and 50 million plastic parts of 5 g to 500 g and motors with a performance of between 20 W and 3 MW.
The local purchasing organisation operates from its production sites in Germany, France, Korea, China and India. Our material group teams are responsible for the cross-group coordination of suppliers, QCD activities (quality, cost, delivery) and internal information exchange about the most important material groups.


Our supplier's general business terms are effective only when and insofar as we have explicitly confirmed them in writing. Provisions agreed by individual contract take precedence over our conditions of purchase if these have been confirmed by us explicitly in writing at the latest by the conclusion of the agreement.


Wilo's Standard Payment Terms - Starting December 1, 2012

Please be advised that the payment terms under Wilo’s standard purchase order terms and conditions have changed to x days end of month (ULTIMO/xD) terms.
Suppliers will be notified by Wilo when the new terms will take effect (the "Effective Date").

Wilo standard payment terms are :

  • 90 days End of Month (ULTIMO /90D)

  • 60 days End of Month (ULTIMO/60D) for European Union Suppliers.

  • 45 days End of Month for DACH and France suppliers.

These new payment terms will initially apply to all purchases made by Wilo governed by Wilo's standard purchase order terms and conditions.


How was the payment term x days End of Month (ULTIMO/xD) selected?

Wilo conducted extensive research, including local directives and benchmarks, and has selected these new payment terms.

Why is Wilo modifying its standard payment terms now?

Wilo's supplier payment terms are significantly below what is considered standard when compared to our industry peers.

May I request that the change in payment terms take place at a later date?

Suppliers will be notified by Wilo when the new terms will take effect. Please contact your usual contact in Wilo purchasing department to discuss changes to your payment terms.

How does this impact open purchase orders, new purchase orders issued, and invoices received on or before the Effective Date?

Invoices against all new purchase orders raised after the Effective Date will be paid as per the new payment terms.

What actions do I need to take?

Please ensure that your Accounts Receivable Department is aware of the new Wilo payment terms.

I have questions about the impact of the new standard payment terms on my business. Who may I talk to?

For questions regarding the new payment terms, please contact your usual contact in Wilo purchasing department.

For general questions not addressed in the FAQs, or if you still have concerns with this change, please do not hesitate to contact your usual contact in Wilo purchasing department before the Effective Date. Be prepared to reference your supplier notification, supplier number, and other relevant payment/supplier information.

Supplier - Compliance


The REACH Regulation (1907/2004/EC) stand for “Registration, evaluation, authorisation and restriction of chemicals” entered into force on 1 June 2007 and aims to improve the protection of human health and the environment through the better and earlier identification of the intrinsic properties of chemical substances.

European Chemicals Agency (ECHA) publishes twice a year an update of the Candidate List of substances of very high concern (SVHC) for Authorisation on its Website. Suppliers of articles, which contain substances of the SVHC Candidate List in a concentration above 0.1% w/w, have to provide information to their customers.

ECHA regularly assesses the substances from the Candidate List to decide, which ones should be included in Annex XIV of REACH regulation (Authorisation list). Substances of the Authorisation list cannot be produced, used or placed on the market after a specified sunset date, unless the use has been authorised or is exempted from authorisation.

Additional to that any hazardous substance can be included in Annex XVII of REACH (Substances restricted under REACH). Annex XVII contains substances for which certain use is limited or forbidden in the European Union.

The RoHS Directive (2011/65/EU) stands for “Restriction of Hazardous Substances in Electrical and Electronic Equipment”, entered into force on 21 July 2011, and aims to improve the protection of the environment through an improved recycling management.

Delegated Directives regularly amend the Annexes of the RoHS Directive, such as modification of the list of restricted substances (Annex II) or dealing with exemptions renewal (Annex III and IV).

Conflict Minerals

The term "conflict minerals" is defined as columbite-tantalite, also known as coltan (from which tantalum is derived); cassiterite (tin); gold; wolframite (tungsten); or their derivatives; or any other mineral or its derivatives determined by the Secretary of State to be financing conflict in the Democratic Republic of the Congo or an adjoining country.
These are also referenced as 3TG (Tin, Tantalum, Tungsten and Gold).


The Data Universal Numbering System, abbreviated as DUNS or D-U-N-S, is a proprietary system developed and regulated by Dun & Bradstreet (D&B) that assigns a unique numeric identifier, referred to as a "DUNS number" to a single business entity. It was introduced in 1963 to support D&B's credit reporting practice. It is a common standard worldwide. DUNS users include the European Commission, the United Nations, and the United States government. More than 50 global, industry, and trade associations recognize, recommend, or require DUNS. The DUNS database contains over 220 million entries for businesses throughout the world.
