Four things the
raw numbers show

Trade data: UN Comtrade, calendar year 2025 (series 2016–2025). State data: DGCIS / NIRYAT, Q4 FY2025-26 (January–March 2026) and FY 2024-25 (April 2024 – March 2025). Page built 27 July 2026.

Standard trade-economics measures, computed from this site’s data and free to download: where India genuinely competes, where its supply is dangerously concentrated, how narrow its customer base is, and where its trade statistics disagree with its partners’.

01

Where India punches above its weight

Revealed advantage by product group.

How this is built. India supplies of everything the fourteen tracked markets import. This index is India’s share of a single product group divided by that overall share, so 1.0 means average and 3.0 means India is three times more present in that product than in its trade as a whole. It is a Balassa revealed-comparative-advantage index computed on the tracked markets rather than on total world trade — directionally the same, but do not quote it as a global RCA.

02

Where India’s imports are concentrated

The largest single supplier’s share of India’s total import bill for each product group. A tall bar is a supply-chain risk.

Read this as exposure, not as a verdict — concentration is efficient until it isn’t. The denominator is India’s own reported world imports of the chapter, so these shares are exact.

03

How narrow is India’s customer base?

Export destinations, by share of India’s goods exports.

Largest single market
Taken by the top five markets
Herfindahl index (0–10,000)

The Herfindahl-Hirschman index is the sum of squared market shares. Competition authorities treat a market above 2,500 as highly concentrated; applied to export destinations, a low number means a country is not dependent on any one buyer. India’s spread is one of the quieter strengths in its trade position.

04

When the two sides disagree

What each partner says it imported from India, against what India says it exported to that partner — same year, same goods, two sets of books.

Why any gap at all is normal — and why big ones are interesting. Partners report imports CIF (including freight and insurance) while India reports exports FOB, so partner figures should exceed India’s by roughly 5–15% as a matter of arithmetic. Gaps far outside that band mean something else: goods re-routed through a third country and re-labelled with India as origin, differences in when a shipment is recorded, or under-declaration. A negative gap — India reporting more than the partner received — usually points to goods declared to a hub and landed elsewhere. This is a signal to investigate, not proof of anything.

About these measures

All four are computed by scripts/build_research.py from the datasets published above — nothing is estimated or modelled. The revealed-advantage and dependence measures use HS 2-digit chapters across the markets this site tracks; the concentration measure uses India’s own reported exports to every partner; the mirror table uses partner-reported imports from India, fetched directly from UN Comtrade.

Known limits: the tracked markets are large but not the whole world, so shares are of tracked trade rather than global trade; chapter-level grouping hides product detail; and merchandise only — services are not in UN Comtrade. See the full limitations.
