Mapping Item Categories
After mapping NetSuite vendors, map item categories between NetSuite and trading partners. The SuiteProcurement SuiteApp leverages the United Nations Standard Products and Services Code (UNSPSC) code set to map the individual sku level item category (UNSPSC code) for each item in the vendor catalog to NetSuite categories (non-inventory Items).
The following image illustrates item category mapping between NetSuite and trading partners.

United Nations Standard Products and Services Code (UNSPSC)
The United Nations Standard Products and Services Code (UNSPSC) is a hierarchical convention that is used to classify products and services. It is an eight-digit numeric code that identifies products and services. For more information, see UNSPSC FAQs.
Benefits of Coding Products and Services
Embedding UNSPSC classification standards into your product management systems — purchase orders, invoices, electronic documents, product catalogs, and websites — benefits all parties throughout the extended supply chain.
Procurement can track how much is spent buying what. This information is available to analyze the specifics in the buying process at the level of detail that most suits the business needs in a timely and precise manner.
It can significantly reduce the time it takes to search products by commodity code through brokers, online exchanges, business partners, or others, across the globe. It allows organizations to spot buying patterns across departments or business units to leverage better conditions from suppliers and realize overall savings.
Finding a Code
You can find UNSPSC codes at UNSPSC. You can retrieve the complete code list from participating vendors. For example, Amazon’s UNSPSC code list can be downloaded from UNSPSC codes for Amazon Business.
By default, the SuiteApp includes default SuiteProcurement category for SuiteProcurement purchases.
All subsidiaries in your account have access to this item list. To access the list, go to the Trading Partner Category column on the Item Category Mapping subtab on the SuiteProcurement Preferences page.
