Differential Port Tariffs in India: Regulatory Limits and Competition Law Concerns
Primary keyword: Differential port tariffs in India
Secondary keywords: Major Port Authorities Act, 2021; Competition Act, 2002; port tariff regulation; abuse of dominance; terminal users; market access; maritime competition law.
Introduction
Ports are an essential part of India’s trade infrastructure. The charges imposed for cargo handling, storage, terminal access and related services influence the cost of importing and exporting goods. For shipping lines, cargo owners and terminal operators, differences in these charges can affect commercial decisions and determine which services remain economically viable.
Different charges are not necessarily unlawful. Handling different categories of cargo may involve different costs, and operators may offer discounts based on volume, service requirements or contractual commitments. The legal concern arises when a price difference lacks a legitimate basis or forms part of conduct that unfairly disadvantages users or restricts competition.
In India, the issue requires an examination of the applicable port legislation, tariff framework, concession agreements and competition law. The Major Port Authorities Act, 2021, permits certain forms of tariff differentiation, while the Competition Act, 2002, addresses conduct such as unfair or discriminatory pricing and denial of market access by dominant enterprises.
The central question is therefore not whether all terminal users must pay identical charges. It is whether the particular difference in pricing is legally permissible, commercially justified and consistent with the applicable regulatory and competition-law requirements.
1. Understanding Differential Port Tariffs
The expression differential port tariffs can refer to several distinct situations. These include differences in charges between cargo categories, variations in rates offered to individual users, different prices for comparable terminal services, and variations arising from separate concession agreements.
These situations should not be treated as legally interchangeable.
For example, a terminal may charge different rates for handling liquid bulk cargo and containerised cargo because the services require different equipment and infrastructure. This is a difference between service categories. By contrast, where two shipping lines receive substantially similar services but are charged different rates, the question is whether their contractual or commercial circumstances justify the difference.
A third situation arises when a terminal operator imposes conditions that require users to obtain a particular service or use particular infrastructure. Such conduct may increase the total cost of using a competing terminal, even where the published tariff itself appears reasonable.
The distinction matters because tariff differentiation, refusal of access, compulsory bundling and exclusionary conduct may raise different legal questions. A sound assessment must identify the actual conduct before determining which statutory provision applies.
2. The Regulatory Framework Governing Port Tariffs
2.1 The Major Port Authorities Act, 2021
The Major Port Authorities Act, 2021, provides the statutory framework for the governance and operation of major port authorities. Section 27 deals with the fixation and implementation of rates.
Under Section 27(1)(f), a Major Port Authority may frame different scales, fees, rates and conditions for different classes of goods and vessels. The provision recognises that a single tariff structure may not adequately reflect the different operational requirements of port services.
However, this statutory power must be read within its proper scope. Section 27(1)(f) specifically addresses different classes of goods and vessels. It should not be treated as an unrestricted, standalone authorisation for every form of differential pricing between individual terminal users.
Section 27 also operates within the wider statutory framework, including the applicable Central Government rules and directions, the Competition Act, 2002, and other laws in force. Tariffs charged by concessionaires may also be governed by the terms of their respective concession agreements and the applicable tariff regime.
Consequently, the legality of a disputed charge cannot be determined merely by referring to Section 27. It is necessary to identify the relevant port, the nature of the service, the status of the operator and the rules or contractual provisions governing that particular tariff.
The Act also should not be assumed to govern every port and terminal in India in the same manner. Major ports governed by this legislation must be distinguished from non-major ports and other facilities operating under different statutory, regulatory or contractual arrangements.

2.2 The Competition Act, 2002
The Competition Act, 2002, provides a separate framework for assessing whether pricing arrangements or other business practices harm competition.
Section 4 prohibits the abuse of a dominant position. Section 4(2)(a) addresses the imposition of unfair or discriminatory conditions or prices in the purchase or sale of goods or services. Section 4(2)(c) concerns denial of market access, while Section 4(2)(e) addresses the use of dominance in one relevant market to enter into or protect another relevant market.
These provisions may become relevant where a terminal operator has significant control over infrastructure or services for which users have limited alternatives.
Nevertheless, a finding of abuse cannot be based simply on the existence of different prices. The relevant market and the enterprise’s dominant position must first be established, followed by an assessment of whether the conduct falls within the statutory prohibition.
Section 4(2)(a) also contains a qualification concerning conditions or prices adopted to meet competition. The commercial circumstances and statutory requirements must therefore be considered before concluding that a price difference is unlawful.
Section 3 addresses a different category of conduct: agreements that cause or are likely to cause an appreciable adverse effect on competition in India, subject to the applicable statutory provisions. It should not be treated as interchangeable with Section 4, which addresses abuse of dominance.
The distinction is important because a unilateral pricing decision and a restrictive agreement may require different legal analyses.

3. When Can Differential Port Tariffs Be Justified?
A difference in port charges may have a legitimate commercial explanation. However, that explanation should be supported by relevant facts rather than merely asserted by the operator.
First, differences in the cost of providing services may justify variations in pricing. Specialised cargo may require dedicated equipment, additional safety measures, temperature-controlled facilities or more intensive handling. Evidence of these differences may help explain why separate tariffs are appropriate.
Second, volume-based discounts and long-term contractual arrangements may reflect genuine commercial considerations. A terminal operator may offer lower rates to a user that commits to a particular volume of cargo or enters into a longer-term arrangement. Such pricing may improve capacity utilisation and benefit both parties.
Third, contractual and regulatory differences may be relevant. Two terminal operators may be subject to different concession agreements or tariff-setting regimes. Their published rates should not be compared without examining the conditions under which those rates were determined.
Finally, differences in service quality, turnaround time, facilities and operating requirements may also be relevant to the pricing assessment.
These factors do not automatically establish legality. A claimed cost difference should be supported by evidence, and contractual flexibility cannot override an applicable statutory prohibition. The relevant question is whether the explanation is genuine, sufficiently connected to the difference in charges and consistent with the governing legal framework.
4. When Do Tariff Differences Raise Competition Concerns?
4.1 Unfair or Discriminatory Pricing
A competition concern may arise where a dominant enterprise imposes unfair or discriminatory prices or conditions within the meaning of Section 4(2)(a) of the Competition Act.
Consider a terminal operator that provides substantially similar services to two shipping lines but charges one considerably more than the other. The difference might be justified by cargo volume, service requirements or contractual commitments. However, if the users are comparable and the operator cannot establish a credible explanation for the difference, the arrangement may warrant closer scrutiny.
The comparison must be based on the actual services and commercial circumstances involved. Differences in invoice amounts alone do not establish discrimination in the legal sense.
The operator’s market position is equally important. A price difference adopted by an enterprise facing substantial competition may have different implications from one imposed by a dominant operator whose customers have few realistic alternatives.
4.2 Infrastructure Access and Denial of Market Access
A separate concern arises where an operator controls infrastructure that competing service providers need to operate effectively.
Suppose a terminal operator requires users to purchase an additional service or use particular infrastructure even when a competing provider could otherwise supply the relevant service. If this requirement increases the cost of using the competing provider and makes its services commercially unviable, it may raise concerns under Section 4(2)(c), depending on the facts.
However, this is not simply a question of differential tariffs. The legal issue may instead concern restrictions on access, compulsory use of infrastructure or conduct that raises a rival’s costs.
The assessment should consider the availability of alternatives, the operator’s position in the relevant market, the commercial justification for the restriction and its effects on competition.
A restriction that is reasonably necessary for safety or technical reasons should be assessed differently from one imposed primarily to protect the operator’s commercial position without adequate justification.
4.3 Cross-Subsidisation and Preferential Treatment
Cross-subsidisation occurs when revenue from one activity supports the pricing or costs of another activity. It is not inherently unlawful.
The competition-law concern arises where the relevant conduct, in the circumstances of the market, may amount to abuse of dominance or form part of an agreement prohibited by Section 3.
For example, a vertically integrated port operator may provide terminal services as well as related logistics services. Preferential pricing could become problematic if it forms part of a strategy that disadvantages competing service providers or protects the operator’s position in a related market.
However, vertical integration, internal cost allocation or preferential pricing alone does not establish a contravention. The relevant market, the operator’s market position, the nature of the arrangement and its competitive effects must be examined.
5. Case Study: East India Petroleum Pvt. Ltd. v. South Asia LPG Company Pvt. Ltd.
The proceedings in East India Petroleum Pvt. Ltd. v. South Asia LPG Company Pvt. Ltd., CCI Case No. 76 of 2011, provide a useful illustration of how infrastructure-access restrictions and associated charges may raise competition concerns in the port sector.
The dispute concerned LPG terminalling infrastructure at Visakhapatnam Port. South Asia LPG Company Pvt. Ltd. (SALPG) operated facilities that included unloading infrastructure and an underground storage cavern. East India Petroleum Pvt. Ltd. (EIPL), another terminal service provider, challenged restrictions that required users to route LPG through SALPG’s cavern and limited the ability to bypass it.
The dispute was not simply about whether different tariff rates could be charged. It concerned the relationship between mandatory use of infrastructure, additional charges and the ability of a competing service provider to offer terminalling services.
In its order dated 11 July 2018, the Competition Commission of India found that the restrictions imposed by SALPG were without reasonable grounds and contravened Section 4 of the Competition Act. The Commission concluded that mandatory use of the cavern and the associated charges had adversely affected EIPL’s business and denied it meaningful market access. It directed measures to provide effective access to the relevant terminalling infrastructure and imposed a penalty.
The decision was challenged before the National Company Law Appellate Tribunal in Competition Appeal (AT) Nos. 69 and 70 of 2018. In its common judgment dated 18 December 2019, the NCLAT dismissed the appeals and directed compliance with the Commission’s order.
The appellate outcome is significant because it confirms the result of the CCI proceedings in this particular dispute. The NCLAT upheld the finding that the restrictions on bypassing the cavern were unreasonable and amounted to an abuse of dominance under Section 4, including denial of market access.
The case nevertheless must be used carefully. It does not establish a universal rule that different port tariffs are unlawful. Its significance lies in the finding that infrastructure restrictions and associated charges, when imposed without reasonable grounds by a dominant operator in the circumstances established, can restrict competition and make competing services commercially unviable.
The case therefore offers a useful comparison for analysing tariff disputes, but it should not be presented as a direct ruling against every form of differential pricing.

6. The Status of the Migration Tariff Guidelines, 2025
The legal status of tariff-related policy documents must be verified before they are relied upon as operative law.
The Ministry of Ports, Shipping and Waterways published a document titled Draft Migration of Tariff Guidelines, 2025 and invited stakeholder comments in March 2025. The stated proposal concerned the adoption of market-determined tariffs for specified public-private partnership projects that had previously been governed by earlier tariff guidelines.
The official publication identifies the document as a draft. The publication alone does not establish that the proposed guidelines were subsequently finalised or brought into force.
Accordingly, the draft should not be described as binding law unless a final instrument or subsequent official notification can be verified. Nor should its proposed provisions be applied automatically to every terminal or concessionaire.
For a particular tariff dispute, the appropriate approach is to identify the existing tariff guidelines, the relevant concession agreement and any applicable notifications or directions. Only after that examination can the legal framework governing the disputed charge be determined.
This distinction is particularly important in legal writing because a proposed regulatory change and an operative legal requirement do not have the same status.

7. Improving Transparency and Regulatory Oversight
A balanced approach to port tariffs should preserve legitimate commercial flexibility while ensuring that the applicable legal requirements are observed.
First, operators should maintain clear records explaining material differences in charges. Where a tariff difference is based on cargo characteristics, service requirements or volume commitments, the relevant evidence should be available.
Second, published tariff schedules should be read alongside rebates, additional charges, bundled services and contractual conditions. The headline rate alone may not reflect the actual cost borne by a terminal user.
Third, tariff disputes should be assessed under the correct legal framework. Differences between cargo categories, discrimination between comparable users and restrictions on infrastructure access raise distinct questions and should not be treated as identical forms of conduct.
Fourth, regulatory scrutiny should remain evidence-based. An operator should not be presumed to have abused its position merely because it offers different rates. Equally, describing a restriction as commercially necessary should not end the inquiry where the available evidence suggests that it may be exclusionary.
Finally, users should be able to identify the applicable tariff regime and the remedies available under the relevant statute, guidelines and concession agreement. Greater transparency can make disputes easier to evaluate and help distinguish legitimate commercial arrangements from potentially unlawful practices.
Conclusion
Differential port tariffs in India raise questions about the relationship between commercial freedom, sectoral regulation and competition law. Different charges may be justified by differences in services, costs, contractual obligations or operational requirements. Their legality, however, depends on the applicable statutory and contractual framework.
Section 27 of the Major Port Authorities Act, 2021, permits different rates for specified classes of goods and vessels, but it should not be interpreted as an unrestricted authorisation for every form of differential pricing. The Competition Act, 2002, separately addresses unfair or discriminatory conduct and denial of market access where its statutory requirements are met.
The East India Petroleum proceedings demonstrate why the analysis must extend beyond headline tariffs. In that case, the competition concern arose from restrictions on access to terminalling infrastructure and the associated charges, rather than from a general prohibition on price differences.
The appropriate legal approach is therefore neither to prohibit all tariff variation nor to treat commercial discretion as unlimited. Instead, each arrangement should be assessed against the governing legal framework, the evidence supporting the price difference and its effect on competition. This approach can preserve legitimate pricing flexibility while addressing conduct that unlawfully disadvantages users or restricts market access.
Frequently Asked Questions
1. Are differential port tariffs illegal in India?
No. Section 27(1)(f) of the Major Port Authorities Act, 2021, permits different scales, fees, rates and conditions for different classes of goods and vessels, subject to the applicable legal framework. Whether a particular arrangement is lawful depends on the relevant statute, tariff regime, concession agreement and facts.
2. When can different port charges amount to an abuse of dominance?
Different charges may raise concerns under Section 4 of the Competition Act, 2002, where a dominant enterprise imposes unfair or discriminatory prices or conditions or engages in other prohibited conduct. The relevant market, dominance and the elements of the alleged abuse must be established.
3. Does the East India Petroleum case prohibit differential port tariffs?
No. The case concerned restrictions on access to LPG terminalling infrastructure at Visakhapatnam Port and the associated charges. The CCI’s findings, upheld by the NCLAT on 18 December 2019, addressed the specific restrictions and their competitive effects. The decision does not establish that every difference in port charges is unlawful.
4. Are the Migration Tariff Guidelines, 2025, binding law?
The Ministry’s March 2025 publication identifies the document as a draft circulated for stakeholder comments. Its publication alone does not establish that it was finalised or brought into force. The status of any subsequent final instrument should be verified before the guidelines are relied upon as binding requirements.
