Last published date: 2021-10-24


As part of the GCC Customs Union, Oman is working toward unifying its standards and conformity assessment systems with those of the GCC through the Gulf Standards Organization (GSO). Oman generally enforces GSO standards. Most Omani standards are either GSO standards or those derived from another international standards organization. Oman is party to the Technical Barriers to Trade Agreement and is a member of the World Trade Organization (WTO). Furthermore, the U.S.-Oman FTA contains a chapter addressing standards as barriers to trade and facilitates bilateral engagement on standards issues.

American businesspeople at times note that Oman employs European standards in tender specifications.


The Directorate General of Specifications and Metrology (DGSM) at the MOCIIP is responsible for standardization, metrology, testing, quality control and quality assurance, conformity assessment and certification, and accreditation activities. Oman is harmonizing its technical regulations and standards at the GCC level and develops technical regulations and standards at the national level only if there is a pressing need, according to authorities.

DGSM’s point of contact and address is the following:

National Institute of Standards and Technology (NIST) Notify U.S. Service

WTO members are required under the Agreement on Technical Barriers to Trade (TBT Agreement) to notify to the WTO proposed technical regulations and conformity assessment procedures that could affect trade. “Notify U.S.” ( is a free, web-based e-mail registration service that captures and makes available for review and comment key information on draft regulations and conformity assessment procedures. Users receive customized e-mail alerts when new notifications are added by selected country or countries and industry sector(s) of interest and can also request full texts of regulations. This service and its associated web site are managed and operated by the USA WTO TBT Inquiry Point housed in the U.S. Department of Commerce’s National Institute of Standards and Technology.

Testing, inspection and certification

DGAW inspects imports of foodstuffs of animal origin to ensure that they are free from contaminants. The U.S. Department of Agriculture (USDA) and other U.S.-based agricultural stakeholders have raised concerns over Oman’s requirement for radiation-free certificates. USDA is engaging with Oman’s government to drop this requirement. Authorities require a manufacturer declaration to assure conformity to Omani/GCC standards. The DGSM should receive a letter with authenticated results of laboratory testing in cases of nonconformity to current standards or the need for consideration of other internationally recognized standards.

Authorities allow non-food products automatic entry to Oman on the basis of a Manufacturer’s Declaration of Conformity Assessment Certificate, with a test report verified by the DGSM Authorities temporarily release and test samples of imported products that are not covered by certificates.

The DGSM requires any laboratory testing certificates relating to conformity to Omani or international standards.

Publication of technical regulations

The DGSM supplies upon request a CD-ROM containing a listing of all standards and specifications adopted by the GSO, along with related information.
