The Innovation and Technology Commission's services in the areas of metrology, documentary standards and accreditation provide the technical foundation for Hong Kong's standards and conformance infrastructure.

The Standards and Calibration Laboratory is the official custodian of Hong Kong's physical measurement standards. It provides a comprehensive calibration service traceable to the International System of Units. It is a signatory to the Mutual Recognition Arrangement for National Metrology Institutes and its service is internationally recognised.

The Product Standards Information Bureau operates a public library and provides sales and a free advice service for documentary standards. The bureau represents Hong Kong SAR in regional and international standardisation bodies and coordinates Hong Kong's input to APEC on standards and conformance matters. It is Hong Kong's Enquiry Point and Notification Authority under the WTO Agreement on Technical Barriers to Trade.

The Hong Kong Accreditation Service grants accreditation status to laboratories, certification bodies and inspection bodies evaluated to be competent through rigorous on-site technical assessments according to international standards and best practices. Through international and regional mutual recognition arrangements in which Hong Kong participates, the results of tests, calibrations, certifications and inspections conducted by accredited organisations are recognised worldwide, thus facilitating various business and trading activities.
