The global trade landscape is shaped by the flow of goods classified under the Harmonized System (HSN) codes, which categorize products for customs and statistical purposes. Understanding trends in trade by HSN code categories provides insights into economic priorities, industrial strengths, and shifts driven by global events (e.g., trade wars, pandemics, technological advancements). This analysis examines export and import trends for selected HSN code chapters globally, using data from the World Integrated Trade Solution (WITS) database. The objectives are to:
Identify high-growth and declining HSN code categories.
Analyze trade dynamics over time (2015–2023).
Highlight factors influencing trade trends (e.g., tariffs, global events).
Data and Methodology
1 Data Source
Platform: WITS, providing access to UN COMTRADE for trade flows and UNCTAD TRAINS for tariff data.
Scope: Global (“World” profile) trade data for exports and imports.
Time Period: 2015–2023 (latest available data up to 2023).
HSN Code Selection:
Selected HS 2-digit chapters for analysis based on trade significance:
Chapter 27: Mineral fuels, oils (key energy sector).
Chapter 84: Machinery, mechanical appliances (industrial and tech goods).
Chapter 61: Apparel, knitted or crocheted (consumer goods).
Used WITS’ “Trade Stats” module to extract export/import values by HS 2-digit codes.
Downloaded data in CSV format for 2015–2023.
Descriptive Statistics:
Calculated mean, median, standard deviation, and growth rates for trade values.
Computed trade shares (% of total world trade) per HSN chapter.
Time-Series Analysis:
Calculated year-on-year (YoY) growth rates:
Applied moving averages to smooth trends and detect long-term patterns.
Used ANOVA to test significant differences in trade growth across HSN chapters.
Contextual Analysis:
Linked trends to global events (e.g., US-China trade war, COVID-19, energy crises).
Referenced tariff data from UNCTAD TRAINS to explore trade barriers.
Tools:
Excel for initial data exploration and validation.
3 Assumptions and Limitations
Assumptions:
Trade values in current US$ reflect market dynamics (inflation not adjusted due to focus on relative trends).
WITS data is comprehensive for global aggregates.
Limitations:
Missing data for some HS 6-digit codes in certain years (addressed by aggregation to HS 2-digit).
Trade volumes less consistently reported than values.
External factors (e.g., geopolitical events, exchange rates) not fully modeled.

Discussion
1 Key Findings
High-Growth Categories:
Pharmaceuticals (Chapter 30): Strong growth (CAGR: 7.1%) driven by health crises and vaccine trade.
Mineral Fuels (Chapter 27): High but volatile growth (CAGR: 6.6%), tied to energy market dynamics.
Steady Performers:
Machinery (Chapter 84) and Electronics (Chapter 85): Consistent growth (CAGR: 4.5–5.0%), reflecting technological and industrial demand.
Lagging Category:
Apparel (Chapter 61): Stagnant growth (CAGR: 1.9%), constrained by high tariffs and shifting consumer preferences.
Global Events:
COVID-19 (2020) reduced trade across all categories, with Chapter 61 hit hardest.
The Russia-Ukraine conflict (2022) boosted Chapter 27 trade values.
US-China trade tensions (2018–2020) moderately impacted Chapters 84 and 85 due to tariffs.
2 Implications
Policy: Low tariffs on pharmaceuticals and electronics support trade; high apparel tariffs may warrant review.
Industry: Investment in technology (Chapters 84, 85) and health (Chapter 30) aligns with trade growth.
Research: Further analysis of HS 6-digit codes could reveal sub-category trends (e.g., semiconductors within Chapter 85).
3 Contextual Factors
Tariffs: Lower tariffs on Chapters 30, 84, and 85 (1.8–2.5%) vs. Chapter 61 (8.7%) correlate with higher trade growth.
Global Value Chains: Chapters 84 and 85 are integral to GVCs, explaining resilience.
External Shocks: Energy and health crises disproportionately affected Chapters 27 and 30.
Conclusion
The analysis of global trade trends by HSN code categories from 2015 to 2023 reveals a dynamic landscape shaped by technological, health, and energy priorities. Pharmaceuticals (Chapter 30) and mineral fuels (Chapter 27) emerged as high-growth but volatile categories, while machinery (Chapter 84) and electronics (Chapter 85) showed steady growth, underscoring their role in global industrialization. Apparel (Chapter 61) lagged, constrained by tariffs and market saturation. These trends reflect the interplay of global events, trade policies, and sectoral demands. Policymakers should prioritize tariff reductions and trade facilitation for lagging sectors, while industries should align with high-growth categories like technology and health.
