Also known as: Commodity Classification, HS Code, Product Taxonomy
Systems that categorize products and services into standardized hierarchies for trade, procurement, and analytics.
DESCRIPTION
Product classification enables consistent identification of goods and services across catalogs, procurement, and customs. The Harmonized System supports international trade and tariffs; UNSPSC and eCl@ss serve procurement and industry classifications. Proper governance ensures version control, multilingual descriptions, and mappings between taxonomies. Accurate classification drives spend analytics, compliance, and supply chain optimization.
ALTERNATIVE DEFINITIONS
World Customs Organization
The Harmonized System (HS) is the world’s most widely used customs tariff nomenclature.
Stresses global adoption for customs tariff and trade.
UNSPSC
The United Nations Standard Products and Services Code (UNSPSC) is an open, global, multi-sector standard for efficient, accurate classification of products and services.
Emphasizes openness and multi-sector procurement classification.
eCl@ss
eCl@ss is the ISO/IEC-compliant industry standard for classifying and describing products and services.
Highlights ISO/IEC compliance and descriptive attributes for industry use.

TOP QUESTIONS
Why is Product Classification important?
It standardizes catalog data, improves spend analytics, enables compliant trade, and reduces duplicate items across systems and suppliers.
Category: Relevancy
How do HS and UNSPSC differ?
HS is for customs and tariffs in international trade; UNSPSC is for procurement cataloging and spend analytics across industries.
Category: Comparison
What are common mistakes in Product Classification?
Using free-text categories, ignoring updates, and inconsistent mapping across taxonomies cause reporting errors and procurement inefficiencies.
Category: Mistakes
How should we manage multiple product taxonomies?
Maintain a master mapping layer with versioned crosswalks, attribute harmonization, and governance to ensure consistent assignments.
Category: Best practices
How often do classification codes change?
HS updates every five years; UNSPSC and eCl@ss publish periodic releases. Track versions and reclassify when necessary.
Category: Management
What metadata should accompany product codes?
Include code, description, hierarchy, version, effective dates, and attributes (e.g., units, material) where supported.
Category: Modeling
How does Product Classification help compliance?
Correct HS codes underpin duties, sanctions checks, and export controls, reducing customs risk and delays.
Category: Compliance
Where to start with Product Classification?
Identify your primary use case (trade vs procurement), then adopt HS or UNSPSC and establish governance for mapping and updates.
