Suppliers Declaration of Conformity

FCC Part 15

Supplier's Declaration of Conformity

The Supplier’s Declaration of Conformity (SDoC) is a procedure that requires the party responsible for compliance to ensure that the equipment complies with the appropriate technical standards. The responsible party, who MUST be located in the United States, is not required to file an equipment authorization application with the FCC. The responsible party or any other party that markets the equipment must provide test reports and other information to demonstrate compliance with the rules upon request by the FCC. Use of the FCC logo on SDoC authorized products is voluntary. The responsible party must compile and retain all pertinent records to show compliance with the FCC rules. The test report showing compliance must be signed by the responsible party. Products authorized using the SDoC procedure must include a compliance information statement in the product user manual, or as a separate sheet with the device. If the manual is only provided digitally, the statement must be included in the digital form of the manual. 1

The information and materials listed at the bottom of this page are required by VPI Laboratories to complete FCC Part 15 Supplier's Declaration of Conformity.  To begin the process, please contact us to request information regarding the FCC testing and procedures.  VPI Laboratories will then issue a written quote for the FCC testing, based on the information received from the initial contact and after reviewing any necessary technical data.  Work will begin when the equipment, required information, purchase order, and the required deposit are received.  The project is generally completed within two to three weeks.  

If the equipment fails to meet the test requirements, VPI Laboratories will notify the client by phone or e-mail to outline the failures. Depending on the service requested by the client, VPI will work to determine and/or correct the possible sources of the failures. If the failures continue, the client may take the following actions:

  • Schedule time to have an engineer familiar with the design and operation of the equipment come to VPI and assist in finding the proper modifications to the unit.
  • Send a list of possible modifications for VPI personnel to make on the unit.
  • Send a unit with modifications already installed.

NOTE: To avoid the delay that failures can create, it is suggested that the client originally send additional samples or a list of modifications for VPI to make as described in the first and second actions above.

If the problems cannot be resolved in a reasonable length of time, the client will be invoiced for the work completed to date on a prorated basis. VPI will continue to assist the client in any way. A new quote will be issued for the remaining work once the corrections have been made.

After the satisfactory completion of the tests, VPI Laboratories will organize the test data and filing materials into a complete Supplier's Declaration of Conformity report. The report will be delivered electronically to the client to be retained in their records.

The client is responsible for meeting labeling and manual requirements. The client must retain a copy of the report and make it available to the FCC upon request.
