NIGP codes are being used as the Category Codes for Contract, Purchase Order, and Sourcing Event line items.
Bidders and Suppliers can self-identify the products/services that they provide. This categorization allows them to automatically receive notifications when public Sourcing Events are created that match the products/services that they provide. This should eventually allow City users to specifically identify Bidders/Suppliers that provide products/services that the City wishes to purchase.
It is useful to understand that these NIGP codes are organized along different levels of complexity, with 3-digit codes representing the broadest categorization levels, 5-digit codes capturing a more detailed level of detail, and with 7-digit codes providing an even more detailed level of product/service categories. Details on these different levels are as follows:
3-Digit Class Code
The 3-digit class code has a brief general description. This level contains 219 commodity/product classes (from 001 to 899) and 55 service classes (from 900-999). The 3-digit code is primarily used to generate periodic expenditure history by department for fiscal planning, budget execution, and accounting.
5-Digit Class-Item Code
The 5-digit class-item code is an expanded version of the 3-digit class code. Our system generally uses 5-digit codes, including 6969 commodity/product classes (from 001 to 89999) and 2427 service categories (from 90000 to 99999).
This 5-digit class-item code incorporates the higher-level, 3-digit class codes, which simply have “00” added to them to fit into a 5-digit class-item code structure. For example, the high-level, 3-digit class code for abrasives is “005”. The 5-digit class-item code for this high-level abrasives category is “00500”.
Subcategories for these high-level codes start with the same first 3 digits, but then have non-zero numbers for the last 2 digits. Using the example of Abrasives from above, the subcategories of abrasives that are part of this higher-level category include “00505” for “Abrasive Equipment and Tools”, “00570” for “Pumice Stone”, and “00584” for “Steel Wool, Aluminum Wool, Copper Wool, and Lead Wool”.
7-Digit Class-Item-Group Code
The 7-Digit Code provides an additional level of purchase description. It contains over 29,000 descriptions. It can be used to develop a specification file and is used with the 11-Digit Code to create a comprehensive purchase description.
