1. Introduction

Customs delays and demurrage liability allocation concern the legal responsibility for charges that accumulate when imported or exported goods remain at a port, airport, container freight station (CFS), inland container depot (ICD), or other storage facility longer than permitted.

The central legal question is:

Who must pay demurrage when cargo clearance is delayed by customs authorities, the importer, the carrier, the port operator, or another party?

In India, the answer depends on the applicable statute, the contract of carriage, the bill of lading, the port or terminal tariff, the cause of the delay, and any binding judicial order.

An important distinction is that the party initially liable to pay a storage or detention charge may not ultimately be the party that must bear the economic loss. For example, an importer might have to settle a lawful terminal invoice to obtain its goods, while separately pursuing recovery from a government authority or contractual counterparty responsible for the delay.

The leading Supreme Court authorities include International Airports Authority of India v. Grand Slam International (1995), Union of India v. Sanjeev Woollen Mills (1998), and Shipping Corporation of India Ltd. v. C.L. Jain Woollen Mills (2001). These decisions establish the principal framework for allocating demurrage liability in India.

2. Meaning of the principal legal concepts

Demurrage

Charges for cargo remaining in a port, terminal, or storage facility beyond the permitted free period, as defined by the relevant tariff or contract. The precise meaning varies by context.

Container detention

Charges imposed under applicable carrier terms when a container is retained outside the terminal beyond the allowed period, typically after it has been taken out for delivery and before it is returned.

Storage charges

Charges for occupying warehousing, terminal, or other storage space. Depending on the applicable rules, these may overlap in commercial usage with demurrage but are not necessarily identical.

Detention certificate

A document issued by customs or another competent authority recording that cargo detention occurred for specified reasons or during a specified period. It does not automatically cancel charges imposed by an independent custodian.

These distinctions matter because a claim concerning terminal demurrage may have a different legal basis from a claim for carrier detention or damages for wrongful customs detention.

3. Legal framework in India

A. Customs Act, 1962

The Customs Act governs customs control, import and export clearance, warehousing, confiscation, and the custody of goods within customs areas.

Important provisions include:

Section 45: Regulates custody of imported goods in customs areas by approved custodians and restricts their release or handling except in accordance with customs requirements.

Sections 47 and 51: Address clearance for home consumption and clearance for export, respectively, subject to applicable statutory conditions.

Sections 110 and 111: Concern seizure and confiscation-related powers in the circumstances specified by law.

Section 141: Addresses conveyances and goods in customs areas.

Section 45 does not, by itself, generally empower customs officials to extinguish a custodian's contractual or statutory entitlement to demurrage. The Supreme Court considered this distinction in Grand Slam International.

B. Major Port Authorities Act, 2021 and applicable port rules

For ports governed by the Major Port Authorities Act, 2021, the port authority's statutory powers, applicable regulations, and approved scale of rates must be considered. Other ports may be governed by different statutory arrangements.

The applicable tariff, free-period rules, exemptions, and any valid waiver policy can materially affect the amount recoverable.

C. Contractual law

The following documents may govern liability between the commercial parties:

Bill of lading and carrier terms.

Shipping-line detention and demurrage tariff.

Port, terminal, CFS, or ICD tariff.

Freight forwarding and customs brokerage agreement.

Sale contract and agreed Incoterms.

Indemnity, delay-allocation, and force-majeure clauses.

Incoterms can allocate costs and responsibilities between buyer and seller, but they do not automatically override statutory obligations or bind a third-party port operator that is not a party to the relevant agreement.

D. Constitutional and public-law remedies

Where a government authority causes an unlawful or unreasonable delay, an importer may seek judicial review or appropriate relief. However, a finding that customs detention was unlawful does not automatically invalidate every independent storage or carrier charge.

The precise remedy depends on the facts, the governing tariff, the parties involved, and the terms of any final court order.

4. Leading case laws and judicial principles

Case 1: International Airports Authority of India v. Grand Slam International (1995)

Supreme Court of India · (1995) 3 SCC 151

Facts: Imported goods were detained by customs authorities during disputes over valuation, classification, or alleged import violations. After the disputes were resolved in the importers' favour, detention certificates were issued. The airport authority and the Central Warehousing Corporation nevertheless sought demurrage under their applicable terms.

Legal issue: Could customs authorities compel statutory custodians to waive demurrage merely by issuing detention certificates?

Decision: The Supreme Court held that customs authorities could not, merely through a detention certificate, extinguish the custodian's independent right to recover charges under the applicable legal and contractual framework.

The Court distinguished the customs-clearance function from the port or airport operator's responsibility to provide storage and handling facilities. These functions are governed by different legal arrangements.

Indian Kanoon+1

Legal principle:

A customs detention certificate is not automatically a waiver of demurrage.

A custodian may remain entitled to charge for the period goods occupy its facilities, even if customs caused the delay.

Any exemption or waiver must be supported by the applicable statute, tariff, binding agreement, valid waiver policy, or court order.

Practical significance: An importer cannot safely assume that a successful customs appeal automatically cancels all port or terminal charges.

Case 2: Union of India v. Sanjeev Woollen Mills (1998)

Supreme Court of India · (1998) 9 SCC 647

Facts: Customs authorities detained imported synthetic waste because they suspected that the goods were higher-value prime fibre. The detention resulted in substantial demurrage.

Legal issue: Could the government be required to bear demurrage arising from customs detention?

Decision and principle: The Supreme Court did not interfere with the High Court's direction requiring the government to bear the charges in the particular circumstances. The decision illustrates that relief can be appropriate where the government's own conduct caused the detention and the circumstances justify shifting the financial burden.

The Court subsequently considered this decision alongside Grand Slam International in C.L. Jain Woollen Mills, explaining that the two decisions were not necessarily inconsistent.

2001 Supreme(SC) 652+1

Practical significance: An importer may have grounds to seek government-funded relief, but the result depends on the specific facts, procedural history, and applicable order. The case does not create a universal rule that customs must pay whenever it causes a delay.

Case 3: Shipping Corporation of India Ltd. v. C.L. Jain Woollen Mills (2001)

Supreme Court of India · (2001) 5 SCC 345

Facts: Polyester filament yarn imported from Korea was detained following customs action. The Delhi High Court later quashed the relevant customs orders and directed release without demurrage or detention charges payable by the importer. The carrier, which claimed a contractual lien over the goods, challenged the position.

Issues:

Could the carrier continue claiming charges under its contract?

Could customs be made responsible for charges attributable to unlawful detention?

Could a detention certificate itself remove the carrier's contractual rights?

Decision: The Supreme Court recognised the carrier's contractual entitlement to charges under the bill of lading, but also upheld the significance of the earlier final High Court order in that particular dispute. Because the customs action had been held unlawful and the applicable court directions had become final, the importer was not required to bear the charges in the circumstances of that case.

The Court further held that Section 45(2)(b) of the Customs Act did not give customs authorities a general power to eliminate the carrier's right to charge demurrage. It also considered it appropriate to permit the relevant corporations to consider waiver on an application by customs.

Indian Kanoon+1

Legal principle: There is a distinction between the custodian's right to levy charges and the ultimate allocation of the burden where unlawful government action has caused the delay.

Practical significance: A carefully framed court order can change the ordinary allocation of costs. Importers should therefore ensure that the carrier or custodian is properly joined where relief is sought directly against its charges, and should not assume that an order against customs alone necessarily binds a non-party carrier.

Case 4: Mumbai Port Trust v. Shri Lakshmi Steels (2017)

Supreme Court of India · Civil Appeal Nos. 9831–9834 of 2017 · Decided 27 July 2017

Facts: Imported steel consignments were held following action initiated by the Directorate of Revenue Intelligence (DRI). The importers sought release and challenged demurrage and detention charges after customs action caused prolonged delay.

Legal issue: Did the existence of a customs detention certificate, together with Regulation 6(1) of the Handling of Cargo in Customs Areas Regulations, 2009, automatically prevent the port from charging demurrage?

Decision: The Supreme Court examined the statutory and regulatory framework, including the distinction between the port's entitlement to charges and the question of who should bear those charges when the detention was unlawful. The judgment reinforces the importance of analysing the precise regulatory text and the facts rather than treating every detention certificate as a universal exemption.

Practical significance: Where DRI or customs investigations cause an extended hold, importers should preserve evidence of the hold instructions, requests for provisional assessment or release, and the dates on which customs could reasonably have acted.

Case 5: Trustees of the Port of Madras v. Aminchand Pyarelal (1976)

Supreme Court of India · (1976) 1 SCR 721

Facts: Customs issued a certificate stating that the goods had remained at the port through no fault or negligence of the importer. The port waived part of the demurrage but later sought to recover the balance after discovering that the certificate had been issued erroneously.

Legal principle: The Supreme Court recognised that the statutory port framework could permit recovery of demurrage even where the delay was not attributable to the importer.

The decision is an important foundation for the later rule in Grand Slam International: absence of importer fault does not, by itself, extinguish the port's statutory entitlement to charges.

Case 6: Caperico International Pte. Ltd. v. Commissioner of Customs (Delhi High Court, 2023)

Delhi High Court · W.P.(C) 16915/2022 · Decision dated 4 January 2023 · Reported as 2023:DHC:000077

Facts: A foreign seller sought release of goods after the Indian buyer failed to pay for the goods and did not clear them by paying the required customs duty. The seller also sought relief concerning accumulated charges.

Relevance: This case illustrates a different source of delay: the importer's own failure to complete payment and clearance formalities. It highlights the need to distinguish delay caused by customs from delay caused by the buyer or consignee.

DHCCaseInfo+1

The lesson is that an overseas seller cannot assume that customs or the port must waive accumulated charges simply because the original buyer has defaulted. The availability of relief depends on ownership, customs procedures, contractual rights, and the facts of the particular case.

5. Comparative summary of the authorities

The decisions must be read together. They do not establish that every demurrage charge is automatically payable by the importer, nor that every charge arising during unlawful customs detention must be waived.

6. Allocation of liability according to the cause of delay

The most useful way to apply these judgments is to identify who caused the delay, who is contractually liable for the charge, and whether a legal remedy shifts the ultimate cost.

Scenario A: Customs authorities cause the delay

Examples: unlawful seizure, erroneous classification, prolonged investigation, or failure to act on a release request.

The importer may remain liable under the terminal tariff or carrier contract. It may separately seek relief against the government where the detention was unlawful or where a specific legal provision or final court order supports recovery. A detention certificate alone does not guarantee a waiver.

Scenario B: Importer causes the delay

Examples: late filing of the bill of entry, failure to pay assessed duty, incomplete documentation, or failure to arrange examination.

The importer will generally bear charges imposed under the applicable contract or tariff, subject to any relevant statutory limits, waiver rules, and proof that another party contributed to the delay.

Scenario C: Carrier or terminal causes the delay

Examples: failure to provide a required document, an avoidable operational hold, or delay in processing a release after all conditions are satisfied.

The affected party may challenge charges attributable to the operator's own breach or seek contractual damages, depending on the evidence and governing terms. The mere existence of a delay does not automatically prove liability.

Scenario D: Multiple parties contribute

Examples: customs holds the cargo while the importer also delays providing documents.

The evidence must establish the relevant periods of delay, the contractual obligations of each party, and whether charges can be apportioned or recovered through separate proceedings. Indian law does not impose one universal formula for dividing all demurrage costs.

7. How contractual allocation works

International trade contracts often allocate expenses between the buyer and seller through Incoterms and bespoke clauses.

Important: Incoterms primarily allocate obligations between the sale-contract parties. They do not automatically determine whether a carrier or port operator can charge a particular party under its separate contract.

For biotech materials, pharmaceuticals, biological samples, and temperature-controlled consignments, the contract should also address cold-storage expenses, dry-ice replenishment, temperature excursions, spoilage, destruction, and emergency release procedures.

8. Remedies available to an importer

An importer facing excessive demurrage should consider the following remedies.

Request provisional assessment or conditional release. Where legally available, seek clearance against the required bond, security, or payment rather than allowing charges to accumulate during a dispute.

Apply for waiver or remission. Submit a documented request to the port, terminal, CFS, ICD, or carrier under the applicable tariff and waiver policy. A customs detention certificate may support the application without guaranteeing success.

Challenge an unlawful customs hold. Depending on the circumstances, seek appropriate relief before the competent appellate authority or High Court, including time-bound clearance or release directions.

Seek an order addressing the correct parties. Where the objective is to prevent recovery of charges by a carrier or terminal, consider whether that entity must be joined and whether the court has a legal basis to grant the requested relief.

Pursue recovery from the responsible party. Depending on the contract, applicable public law, and evidence, consider a claim for reimbursement, damages, indemnity, or other available relief.

Preserve the evidence. Maintain customs notices, examination reports, emails, bills of entry, release applications, invoices, tariff schedules, detention certificates, and a date-by-date record of the delay.

9. Evidence needed to establish liability

The strength of a demurrage claim frequently depends on proving exactly when the goods could have been cleared and why they remained uncleared.

A particularly important distinction is between the date customs released the goods and the date the goods were actually removed. Further delay after customs release may be attributable to unpaid charges, missing transport arrangements, incomplete documents, or other independent causes.

10. Calculation of demurrage liability

A basic calculation can be expressed as follows:

\[ \text{Chargeable days} = \max(0,\text{days held}-\text{free days}) \]

\[ \text{Demurrage} = \sum_{d=1}^{n}(\text{applicable daily rate}_d \times \text{chargeable units}_d) \]

This is a simplified illustration. Actual tariffs may use slabs, weekends, part-days, weight, volume, package count, container type, or different rates at different stages.

For example, assume:

Total terminal stay: 20 days.

Free period: 5 days.

Daily charge: ₹4,000.

No escalation, additional handling, or waiver applies.

The illustrative charge is:

\[ (20-5)\times ₹4,000 = ₹60,000 \]

The ₹60,000 is the calculated charge, not a conclusion about who ultimately bears it. That question requires the applicable contract, tariff, cause of delay, and any relevant court order.

11. Application to biotechnology and pharmaceutical imports

For biological products, vaccines, cell cultures, reagents, diagnostic kits, and other sensitive materials, customs delays can create losses that greatly exceed the demurrage invoice.

The liability analysis may involve:

Customs and regulatory approvals: Whether required import permissions, product licences, or supporting certificates were available and correctly filed.

Cold-chain preservation: Which party had responsibility for maintaining the specified temperature during the hold.

Product deterioration: Whether the goods became unusable, and whether the deterioration resulted from a party's breach or an unavoidable regulatory hold.

Mitigation: Whether the parties sought priority examination, appropriate storage, provisional release, or other reasonable measures to minimise loss.

Insurance and indemnity: Whether cargo insurance or contractual provisions cover the relevant storage costs and damage.

Demurrage, cargo deterioration, and consequential business losses are distinct heads of claim. Recovering one does not automatically establish entitlement to the others.

12. Conclusion

Indian case law establishes three central principles.

First, Grand Slam International confirms that a customs detention certificate does not, by itself, cancel an independent custodian's entitlement to demurrage.

Second, Sanjeev Woollen Mills and C.L. Jain Woollen Mills show that, in appropriate circumstances, the government may have to bear charges resulting from its own conduct, particularly where unlawful detention and a binding judicial order support that outcome.

Third, the applicable tariff, contract, statutory framework, and factual cause of delay must be examined before determining final liability.

The correct legal approach is therefore to distinguish the initial obligation to pay the custodian, the party responsible for causing the delay, and the party ultimately required to bear the loss.

Scope note: This explanation focuses on Indian law. The outcome in a particular dispute may differ according to the port, custodian, contractual terms, applicable regulatory provisions, and the precise relief granted by a court. For a live claim, the current legislation, applicable tariff, and complete judgments should be checked before taking legal action.
