Invoicing Instructions

US Ecology's Terms and Conditions and contracts contain most of the invoicing instructions and information your company needs.

In addition, here are a few requirements that merit extra emphasis to US Ecology suppliers:

  • Send one invoice.
  • Handwritten changes, or carbon copies of invoices are not acceptable.
  • Duplicate invoices are not acceptable.
  • If at any time, duplicate invoice billings are identified, the duplicate invoice will be returned to you and an administrative fee will be charged to the first invoice.
  • Clearly show the Purchase Order number (and release number, if a blanket agreement) on the invoice.
  • Invoices received without a valid purchase order number (and release number, if applicable) will be returned to the supplier unpaid.
  • Provide your company or division name and indicate your unique invoice number and invoice date. The invoice number must NOT recycle within a minimum of 36 months.
  • Indicate the unit quantity shipped, unit cost, extended cost. The invoice cost must not exceed 2 decimal places to the right.
  • Indicate applicable taxes as a separate line item.
  • Indicate freight charges as a separate line item. Freight shall be "prepaid and collect" unless otherwise designated on the purchase order.
  • Clearly indicate the remit-to address.
  • Invoices must be sent directly to our Accounts Payable department at:
