• It has 13 data fields that were not part of the 29-question Census 2011 schedule.
• Question 10 reads: Scheduled Caste (SC)/Scheduled Tribe (ST)/Caste.
• Caste will be entered in an open column as declared by the respondent.
• This is the first Census in Independent India to enumerate caste beyond SCs and STs.
• The 2011 SECC returned more than 46 lakh caste names; the 1931 Census had recorded 4,147 castes.

Mains Perspective

GS-II: Governance, Social Justice and Welfare Policies

Revision Note: Caste data can improve targeted policymaking, but an open-column method may create classification errors. Reliable enumeration requires standardisation, transparency, privacy safeguards and a clear plan for using the data.

2. MMDR Amendment Bill 2026 Raises Federalism Concerns

Why in News?

Kerala’s ruling front and Opposition, along with leaders in mineral-rich Odisha, opposed the Mines and Minerals (Development and Regulation) Amendment Bill, 2026. They argued that restrictions on State taxes and cesses over mineral rights and mineral-bearing land would weaken fiscal autonomy.

UPSC/PCS Importance

3. U.S. Report Links India to Chinese Tariff Transshipment

Why in News?

A White House report titled The Great Transshipment Scam alleged that Chinese goods were being routed through more than 40 countries to evade U.S. tariffs. It identified India among the top-risk hubs and specifically referred to the Pune-Gujarat-Chennai production belt.

UPSC/PCS Importance

Highly important for India-U.S. relations, global trade, rules of origin, tariff arbitrage, trade protectionism, supply-chain restructuring and India’s manufacturing credibility.

Prelims Facts

• Transshipment involves routing goods through an intermediate country before they reach the final market.
• Tariff arbitrage exploits differences in tariff rates across countries.
• Limited assembly, finishing, repackaging, relabelling or documentation changes may falsely create a different origin.
• The U.S. report identified more than 40 countries with elevated illegal-transshipment risk.
• Its Tier 1 includes India, Canada, the EU, Israel, Japan, Mexico, South Korea and Taiwan.
• The report estimated that $67 billion in U.S.-bound Chinese goods passed through Mexico, India and Vietnam in 2025.

• Rules of Origin determine the economic nationality of a product for trade-policy purposes.

Mains Perspective

GS-II: India-U.S. Relations
GS-III: International Trade and Economy

Revision Note: India must distinguish genuine value-added manufacturing from mere relabelling by strengthening customs enforcement, origin verification and supply-chain traceability without disrupting legitimate trade.

4. Supreme Court Questions BCI Action Against NALSAR Graduates

Mains Perspective

GS-II: Fundamental Rights, Judiciary, Education and Regulatory Bodies

6. Strait of Hormuz Crisis Makes Oil Prices a U.S. Priority

Why in News?

U.S. Vice-President J.D. Vance said keeping oil and gas prices low had become the immediate priority in the Iran conflict, ahead of preventing Iran from acquiring a nuclear weapon. Iran’s near-closure of the Strait of Hormuz has given Tehran major bargaining leverage.

These claims had not been confirmed in the report by the government.

UPSC/PCS Importance

Important for India-China relations, Line of Actual Control management, border infrastructure, patrol access, traditional grazing rights and civil-military coordination in remote frontier areas.

• Trade Diversion
• Substantial Transformation
• Value Addition
