Commodity codes

Commodity codes are standard classification numbers describing what is being bought — the shared vocabulary that lets a buyer label a purchase, a supplier label itself, and a database match the two. Public systems use national and international schemes; private buyers often use their own item masters; the function is identical: codes make markets searchable at scale.

Suppliers interact with codes mostly at registration and mostly get them wrong quietly. The codes on a supplier file decide which opportunity notices arrive and which category searches return the firm; a supplier misclassified under adjacent codes is invisible to exactly the buys it can win, and nothing in the process sends a warning. The fix is unspectacular: register under every code you genuinely sell, revisit after each product-line change, and test by searching the opportunity feed as a buyer would. Free aggregators such as pubsec.pro expose code-filtered feeds across federal and provincial sources, which makes the classification testable rather than theoretical.
