NAICS 541380: Testing Laboratories and Services

What this code covers

Performing physical, chemical, and other analytical testing services.

If this code describes the activity that generates most of your revenue, it is a candidate for your primary NAICS code; if it covers adjacent work you genuinely perform, list it as a secondary code. In US federal contracting, the NAICS code on a solicitation also fixes the SBA size standard that decides whether your firm counts as a small business for that competition.

Using this code in Canada

NAICS is jointly maintained by the United States, Canada, and Mexico, so 541380 means the same thing on both sides of the border. Canadian federal tenders on CanadaBuys, however, are primarily categorized with UNSPSC codes (and legacy GSINs), so Canadian suppliers should identify their UNSPSC categories as well — see the GSIN code lookup and the GSIN explainer.
