Criteria for Providing Service

Under certain circumstances, NIST is authorized to provide measurement services, including calibration services, for organizations or individuals located outside the United States. However, the NIST Calibration Program must review each request for calibration services to determine if services are available to the requestor's organization in the requestor's country. Foreign customers must provide the following information, in writing, to the Calibration Program (see address above):

  1. Identification of the item(s) to be calibrated, including serial and model numbers.
  2. A detailed description of the measurements that are needed, or indicate the service identification number.
  3. A description of any special requirement/circumstance that might affect the decision to provide the service. For example, will adjustments have to be made to the instrument, or will the time period be restricted in which the device is available for calibration?
  4. A complete name and address of the requestor's organization.

Special Instructions

If the request for calibration service is accepted by NIST, the requesting organization will be notified of the cost of service and will be given the contact information for the NIST technical unit that will perform the measurements. The requesting organization must then complete the following steps:

  1. Contact the NIST technical unit that will provide the service to determine the schedule.
  2. Send a purchase order to the Calibration Program. Provide complete addresses, including country, for returning the instrument and for mailing the calibration or test report.
  3. NIST policy requires prepayment for all NIST calibration services requested by non-U.S. organizations. Before proceeding with any service(s) we will need a check, money order or a bank wire transfer. The prepayment must be for the full amount and be drawn on a U.S. bank. The prepayment methods are as follows:

Money Orders & Prepayment Checks

All foreign checks must be drawn on a United States Bank and made payable in US Dollars. All foreign checks must be mailed to the Receivables officer for deposit.

Shipping Charges

Before shipping the instrument or standard to the appropriate NIST technical unit, you must arrange with a customs broker for entry of the instrument into the U.S. with transportation to and from the port of entry to NIST prepaid. Air freight is most satisfactory. Entry bond is required for instruments not manufactured in the U.S. If arrangements are made with a broker in the country of origin, that broker should, in turn, have a U.S. customs broker in or near the port of entry to arrange for the entry of the instrument and its transportation to NIST. Direct arrangements can be made with customs brokers located in the Washington, DC/Baltimore, Maryland, metropolitan area or in the Denver, Colorado, area, as appropriate. These brokers must arrange for transportation to the port of exit after testing/calibration is completed.

The calibration costs quoted do not included shipping, insurance, or the services of a customs broker. You must arrange and pay for these services separately. For your information, NIST currently uses the following customs brokers:

Gaithersburg, Maryland
Laing International
P.O. Box 16144
