Every day your container sits uncollected at an Indian port after its free period ends, you are paying. Demurrage and detention charges are among the most avoidable yet most common financial drains for importers in India — and in 2026, with port congestion, new BIS and EPR compliance requirements, and volatile vessel schedules driven by Red Sea disruptions, the risk is higher than ever.
This guide breaks down exactly what causes demurrage and detention at ports like JNPT (Nhava Sheva), Mundra, Chennai, Kolkata, and Delhi Air Cargo — and how to prevent them entirely.
What Is Demurrage? What Is Detention?
These two terms are often confused but they refer to distinct charges:
- Demurrage — charges for keeping the container inside the port or terminal beyond the free days. Charged by the port or terminal operator.
- Detention — charges for keeping the container outside the port (such as at your warehouse) beyond the free days. Charged by the shipping line.
- Ground Rent — storage charges at the port for cargo not picked up after customs clearance. Charged by the port or CFS.
The free period is typically 3–7 days at most Indian ports. Once it closes, charges begin — and they escalate rapidly with every passing day.
At JNPT, demurrage can run from ₹5,000 to ₹35,000 or more per container per day. Mundra and Chennai charge similar rates. A 20-day delay on a single 40-foot container can easily cost over ₹2 lakh in demurrage alone — before factoring in shipping line detention and CFS ground rent.
Why Are Demurrage Costs Rising in 2026?
Red Sea Disruptions and Vessel Rollovers
Extended detours around the Red Sea via the Cape of Good Hope have created cascading delays. Shipping lines are issuing ad-hoc cancellations at Mundra and JNPT with less than 48 hours' notice — cargo gets rolled to the next vessel and sits at port for 10–14 extra days, triggering storage charges that importers never planned for.
BIS and EPR Certification Holds
The single biggest cause of customs holds in 2026 is BIS and EPR certification mismatches. If your product falls under a mandatory BIS category and the certificate is missing or shows any discrepancy, customs places an automatic hold. Your container sits accruing demurrage while the paperwork is resolved.
Late Bill of Entry Filing
Filing the Bill of Entry after vessel arrival — instead of in advance — compresses your clearance window dangerously. Every hour of delay after arrival increases your demurrage exposure.
Valuation Disputes
If customs raises a valuation query, clearance is paused until it is resolved. Even with the new three-query limit in 2026, disputes still take time.
Payment Delays
Delay in paying assessed customs duty after the Final Out-of-Charge is issued means goods stay in port even after clearance — continuing to accumulate charges.
A 20-day delay on a single 40-foot container can easily cost over ₹2 lakh in demurrage alone — and it is almost entirely preventable.
10 Proven Ways to Avoid Demurrage and Detention
1. File the Bill of Entry Before Vessel Arrival
Under Indian Customs rules, you can file a Bill of Entry up to 30 days before the expected arrival of the vessel. Advance filing gives customs time to assess — so by the time the ship docks, your clearance may already be ready.
2. Ensure All Certificates Are Ready Before Shipment
Before goods leave the origin country, confirm you have the correct BIS Certificate, EPR Registration, FSSAI Licence, CDSCO approval, or any other product-specific permit. A single missing certificate creates an automatic hold.
3. Verify Your HS Code Before Filing
An incorrect HS Code triggers re-assessment, additional queries, and physical examination. Get your classification verified by a licensed CHA before filing.
4. Check IEC and GST Linkage
Your Importer Exporter Code must be active and correctly linked with your PAN and GSTIN on ICEGATE. Mismatches cause filing rejections that delay your entire clearance timeline.
5. Monitor Vessel ETA Daily
Vessel schedules are volatile in 2026. Track the ETA through your shipping line or freight forwarder and be ready to accelerate document submission if the vessel arrives early.
6. Pre-arrange Duty Payment
Have your customs duty funds ready before the OOC is issued. The moment duty is assessed, pay immediately. ICEGATE 2.0's UPI and card payment option makes this instant.
7. Pre-arrange Transport from Port
Book your truck or container transport before clearance is confirmed. The moment OOC is issued, goods should be able to move without waiting for a transporter.
8. Negotiate Free Days with Your Shipping Line
For regular importers with consistent volumes, shipping lines often grant extended free periods of 7, 10, or even 14 days. Your CHA or freight forwarder can negotiate this at the time of booking.
9. Choose a CFS with Lower Dwell Charges
If cargo must move to a Container Freight Station, compare ground rent rates. A knowledgeable CHA can guide you toward cost-effective options.
10. Involve a Licensed CHA from Day One
The single most effective way to avoid demurrage is to engage a licensed Customs House Agent the moment your shipment is booked — not after the vessel arrives. A proactive CHA monitors ETAs, pre-files documents, coordinates with the port, and ensures your goods move out within the free period.

What to Do If Demurrage Has Already Started
If your shipment is already in the demurrage period, move immediately:
- Contact a licensed CHA right away and share all shipment documents — BL or AWB, invoice, packing list, and any customs correspondence.
- Identify the root cause — documentation hold, customs query, or missing certificate.
- Resolve the root cause first — filing an extension request without fixing the underlying problem buys very little time.
- Apply for the port gate pass the moment OOC is issued.
- Request a waiver from the shipping line — in cases of force majeure such as vessel delays or port congestion, lines sometimes grant partial waivers with supporting documentation.
Port-wise Free Period Overview
- JNPT / Nhava Sheva — 3 to 5 free days, demurrage ₹6,000–₹35,000/day per container
- Mundra (Gujarat) — 4 to 5 free days, demurrage ₹5,000–₹28,000/day per container
- Chennai Port — 3 to 5 free days, demurrage ₹5,500–₹30,000/day per container
- Kolkata / Haldia — 3 to 4 free days, demurrage ₹4,500–₹22,000/day per container
- Delhi Air Cargo (IGI) — 2 to 3 free days, charged per kg per day slab
- Hyderabad Air Cargo — 2 to 3 free days, charged per kg per day slab
Rates vary by terminal operator, container type, and shipping line. Always confirm current rates with your CHA before each import cycle.
Common Questions
Can demurrage charges be waived? In some cases, yes — particularly when delays were caused by force majeure events such as vessel delays, port strikes, or system downtime. Waivers require documentation and are not guaranteed.
Who is responsible for demurrage — the importer or the CHA? The importer is legally liable for demurrage. If the delay was caused by a filing error on the CHA's part, you may have grounds for a claim against them. This is why the choice of CHA matters.
How early should I contact a CHA before my shipment arrives? Ideally, the moment your purchase order is confirmed and the shipment is booked. Advance Bill of Entry filing is possible up to 30 days before vessel arrival — early engagement maximises your clearance window.
The Bottom Line
Demurrage and detention are not just inconvenient — they are a significant, recurring cost that directly erodes your import profitability. In 2026, with vessel disruptions, stricter certification requirements, and rising port charges, the margin for error is thinner than ever. Virtually all demurrage is preventable with the right preparation, the right documentation, and the right customs partner.
