The UNSPSC® or United Nations Standard Products and Services Code® is a global system for classifying different types of goods and services, similar to a tariff code. This code is a not customer-specific number. Customers, such as CIS (a Basics Group in Canada), may request this information to include in their specs, but not all customers have requested this before.
If an item has a UNSPSC code, it is stored in the FAQ & Spare Part subtab of the item record in NetSuite.
An example of a UNSPSC code is below:
Item #: 11880 (EZ Mount Frame)
UNSPSC Code: 60121406
Some websites, such as iteminfo.com, will include the code.
This website will allow you to search for the Code Number or by the Code Name/Title.
