Weighing authorities by country

Who approves weighing equipment, and where to verify it — 36 OIML certificate-issuing authorities across 30 countries, plus how NTEP, Measurement Canada, OIML and the EU MID relate to each other.

Reference material. The tools a scale owner uses every day are on the Resources page; this page is for checking an approval claim from another country. United States first, Canada second, the rest of the world after.

WHAT THIS PAGE IS

Weighing equipment is approved differently in almost every country. This page lists the bodies that issue OIML certificates — the international type-approval scheme — so you can go straight to the right authority and verify a claim yourself. ScaleRegistry is a registry, not a regulator: we record and link, we do not approve equipment and we do not issue certificates.

United States: NTEP

NTEP (United States)A National Type Evaluation Program Certificate of Conformance, issued through NCWM. This is what a US weights & measures inspector looks for on a commercial scale. Verify in the NCWM database.

Canada: Measurement Canada

Measurement CanadaCanada does not work state-by-state. One federal authority approves devices and authorizes the private companies that inspect and certify them. Verify at ised-isde.canada.ca/site/measurement-canada.

International: OIML certificates and the EU MID

OIML-CS (international)An OIML certificate is a type-approval issued under an international recommendation (R76 for nonautomatic weighing instruments, R60 for load cells, and others). Many countries accept or build on it. Verify in the OIML-CS register.

MID (European Union)Instruments placed on the EU market are covered by the Measuring Instruments Directive and assessed by notified bodies. National authorities below are the starting point for the country you are selling into.

These are not interchangeable. A device can hold an NTEP certificate and no OIML certificate, or the reverse. Check what the jurisdiction you operate in actually requires — and confirm it with the authority, not with us.

OIML certificate-issuing authorities

36 authorities across 30 countries. The certificate counts are not each authority’s total output — they count how many of the 1,741 certificates held by the brands listed in this registry were issued by that authority. A country showing none simply means none of the brands we list hold a certificate issued there. Countries with no certificate among our brands are left out of the table (see the full list in the OIML-CS register).

Canada is not in this table, and that is correct. Measurement Canada regulates weighing in Canada but is not an OIML-CS certificate-issuing authority, so it does not appear in OIML’s list. The same is true of several countries that run their own national approval schemes. Absence here means “does not issue OIML certificates” — never “unregulated”. For Canada see Measurement Canada and our Measurement Canada authorized providers by province.
