6. Remission of Duties and Taxes on Exported Products (RoDTEP) Scheme
The Government of India has recently reinstated RoDTEP scheme benefits for exports made by Advance Authorization (AA) holders, Export-Oriented Units (EOUs), and Special Economic Zone (SEZ) units.
About RoDTEP Scheme:
-
Introduced via an amendment to the Foreign Trade Policy (2015–20), RoDTEP came into effect on January 1, 2021.
-
Its objective is to reimburse embedded taxes and duties on exported products that are not credited or refunded through any other scheme.
-
It aims to improve export competitiveness by offsetting such taxes, including those at central, state, and local levels.
-
RoDTEP is WTO-compliant and operates on a fully digital platform to ensure transparency and efficiency.
-
It replaced the Merchandise Export Incentive Scheme (MEIS) following a WTO challenge from the US.
-
The scheme is administered by the Department of Revenue under the Ministry of Finance.
Tax Reimbursement Mechanism:
-
The scheme covers unrefunded taxes and levies incurred during manufacturing and distribution.
-
It includes both direct costs and accumulated indirect taxes at prior stages.
Eligibility Criteria:
-
Applicable to all goods exporters regardless of turnover, provided the goods are manufactured in India.
-
Both merchant and manufacturer exporters are eligible if the goods are exported directly.
-
Priority is given to labor-intensive sectors previously supported under MEIS.
-
EOUs, SEZ units, and exports via e-commerce platforms are eligible.
-
Re-exported goods are excluded.
Refund Process:
-
Reimbursement is provided as a percentage of the Free on Board (FOB) value.

Exporters receive transferable electronic scrips (e-scrips), maintained in the electronic credit ledger by CBIC.

These e-scrips can be used to pay basic customs duty or transferred to others.
7. Bow Echo
Recent severe storms in Delhi displayed a distinct bow-shaped pattern on radar, known as a bow echo.
What is a Bow Echo?
-
A bow echo appears as a curved squall line on radar, extending 20 to 100 km and lasting 3–6 hours.
-
The term was coined by meteorologist Ted Fujita in the 1970s.
Formation Process:
-
Rain-cooled air descends and spreads out, forming a gust front with warm-moist surface air.
-
This front lifts warm air, generating new thunderstorms, which in turn produce more rain-cooled air, sustaining the gust front.
-
Continuous thunderstorm formation and inflow at the rear cause the line to bend like a bow.
-
The cycle persists until storm formation ceases.
-
Similar phenomena were observed in Delhi and Noida in 2022, with winds reaching 100 km/h.
