General Questions

Q. Some of these processes are different from the ones I previously used. Why have they changed?

As part of the Dow Corning Corporation integration onto The Dow Chemical Company's SAP/Enterprise Resource Planning (ERP) system, the combined organizations have transitioned many of Dow Corning processes onto Dow's.

Q. I work with multiple Dow Corning regions. Have the processes also changed for them?
A. Phase 1 & 2: Yes, process changes are in effect for in Europe, Asia Pacific, Latin America, and North America.

Purchase Orders / Invoicing

Q. What has happened with my open Dow Corning purchase order(s)?
A. Phase 1 & 2:
All open purchase order lines with remaining goods receipt quantities were recreated in Dow's ERP system and given a new purchase order number. A mapping file is available under the Purchase Order Cross-Reference resource page. You can use the search functionality on the page to find the new purchase order number. Alternatively, you can download an excel file of the full purchase order cross reference.

Q. I have done business with Dow Corning in the past. Where do I send my invoices now?
A. Phase 1 & 2:
Our preference is for invoices to be emailed. For the location to email your invoice, please see the Company Code Cross-Reference. If the invoice must be mailed, please refer to the company code cross reference to find the invoice mailing address.

Q. I searched through purchase order cross reference and do not see my Dow Corning purchase order?
A. Phase 1 & 2: 
All open purchase order lines with remaining goods receipt quantities were recreated in Dow's ERP system and given a new purchase order number. If you purchase order was fully received it was not migrated to the new system. In this case, you will invoice based on the original Dow Corning purchase order.

Q. I used to receive aggregated POs for a given location, but that no longer seems to be the case, is that accurate?
A. Phase 1 & 2:
 You are correct. Dow does not aggregate Purchase Orders, so you will receive POs from requesters as they are submitted and released.

Q. During the integration / interim period, how do I know the correct Legal Entity name for my invoice?
A. Phase 1 & 2:
Please refer to the Company Code Cross-Reference page. Information is continually being updated, please return to this site for updates.

Q. If I need to send in a Service Entry Sheet Template (SES Template) which represents my invoice, where do I find a copy of that template to send?
A. Phase 1 & 2:
 The SES Template is available here (xlsm)

Q. How do I know the correct Legal Entity to invoice?
A. Phase 1:
For purchase orders issued to you prior to November 1, 2017, please see the supplier communication from November 8, 2017 under prior communications for more information. For purchase orders issued to you on or after November 1, 2017, you should follow the information on the purchase orders.

For purchase orders issued to you on or after February 1, 2018, you should follow the information on the purchase orders.

Q. I sent my invoice to Dow Corning, do I need to resubmit my invoice to Dow?
A. Phase 1:
No, provided you received the purchase order from Dow Corning prior to November 1, 2017, and the invoice is received for payment prior to November 30, 2017. If you received the purchase order after November 1, 2017 or your invoice is received for payment after November 30, 2017, you will need to submit your invoice in alignment with the company code cross reference.
Phase 2: No, provided you received the purchase order from Dow Corning prior to February 1, 2018, and the invoice is received for payment prior to February 28, 2018. If you received the purchase order after February 1, 2018 or your invoice is received for payment after February 28, 2018, you will need to submit your invoice in alignment with the company code cross reference. Please note this grace period is NOT applicable for India, Singapore, Taiwan, Philippines or Brazil.
PLEASE NOTE: for invoices to Dow legal entities in India, Singapore, Taiwan, Philippines or Brazil – ALL invoices dated February 1 or later MUST be to the new Dow legal entities.

Q. Why did my invoice get returned?
A. Phase 1 & 2:
 There are various reasons that we return invoices to a vendor. Examples include: Invoice is addressed to the incorrect Legal Entity, Invoice is missing correct tax, Invoice is missing a valid purchase order or reference, Purchase order is paid in full. The return to vendor letter will detail the reason why the invoice is being returned.

Q. Why am I receiving purchase orders from Dow Europe GmbH?
A. Phase 1 & 2:
Dow operates in EMEA with a central procurement company. Dow's central procurement company in EMEA is Dow Europe GmbH. This company has VAT registrations in 15 different EU countries. The VAT numbers can be found on the Company Code Cross-Reference page. Many products and services, especially raw materials and packaging, will be purchased by Dow's central procurement company from November 2017 onwards for many Europe sites. According to the EU VAT Directive, Dow Europe GmbH's VAT number should be specified on your sales invoices. In this regard, we would appreciate if you would take the following VAT rules into consideration:

  • For any service that you provide to Dow Europe GmbH, please use the Swiss VAT number of Dow Europe GmbH.
     
  • For any product that you sell and transport to an EU country, we would appreciate if you use the SHIP TO country VAT number of Dow Europe GmbH on the invoice.
     
  • In case, you sell a product to an EU country where Dow Europe GmbH does not have VAT number or when the products remain within an EU country, please use Dow Europe GmbH's VAT number of the SHIP FROM country.
     
  • In case, you are shipping a product to an EU country where Dow Europe GmbH does not have an EU VAT number, nor does it have a VAT number in the SHIP FROM country, please use the Dutch VAT number of Dow Europe GmbH.
