How China's 2026 Maritime Code and Arbitration Law Change Enforcement of Contracts of Carriage and Supply Contracts

Two landmark reforms now govern how contracts of carriage in China are drafted, disputed and enforced. The revised Arbitration Law, effective 1 March 2026, reshapes seat analysis, clause validity requirements and the procedural framework for commercial arbitration across every sector. Barely two months later, on 1 May 2026, the revised Maritime Code and accompanying supply-chain regulations introduced unwaivable minimum standards for sea carriage touching Chinese ports, fundamentally altering the risk calculus for carriers, shippers and commodity traders. Together, these changes mean that any party with cargo loading at or discharging in a Chinese port, or with supply-chain contracts performed partly in China, must reassess choice-of-law clauses, arbitration seats, interim-relief options and enforcement strategies immediately.

Quick Reference: Key Dates and Headline Changes for Contracts of Carriage in China

Before examining the detail, practitioners need a clear timeline. The table below maps each reform to its effective date and the most significant practical consequence for China contract disputes.

The combined effect is that parties can no longer rely on a foreign governing-law clause alone to insulate their contractual arrangements from Chinese mandatory rules. Industry observers expect this dual reform to accelerate the shift towards China-seated arbitration for high-value maritime and supply-chain disputes.

How the Maritime Code 2026 Changes Contracts of Carriage and Supply Contracts

Scope: What “Touching a Chinese Port” Means

The revised Maritime Code applies its mandatory provisions to any contract of carriage by sea where the port of loading or the port of discharge is located in China. This is not limited to Chinese-flagged vessels or Chinese counterparties. A bill of lading issued in London for cargo loaded at Tianjin, or a charter-party for grain discharged at Qingdao, will both fall within scope.

The trigger is strictly geographic: if cargo physically crosses a Chinese port terminal, the code’s minimum standards attach. Industry analysis confirms that this represents a significant expansion from the pre-2026 position, where parties could more readily contract out of Chinese liability rules by choosing a foreign governing law. Practical examples of shipments now caught include:

• Export shipments. Containerised goods loaded at Shanghai, Shenzhen or Ningbo destined for any foreign port.
• Import shipments. Bulk commodities (iron ore, LNG, crude oil) discharged at Dalian, Tangshan or Guangzhou.
• Transhipment with a Chinese leg. Cargo transhipped at a Chinese hub port where the bill of lading names the Chinese port as a loading or discharge point.

Unwaivable Minimum Standards for Carriers

The most consequential change for china maritime contracts is the introduction of minimum liability standards that parties cannot contract out of. P&I insurer commentary confirms that the revised code establishes mandatory floors for carrier liability on loss, damage and delay, and that any contractual clause purporting to reduce liability below these floors is void as a matter of Chinese law. This applies regardless of the governing law chosen in the bill of lading or charter-party.

The key mandatory provisions include:

• Minimum liability limits. Carriers must accept liability up to prescribed per-package and per-kilogramme thresholds. Clauses that cap liability below these levels are unenforceable in Chinese courts.
• Prohibited exclusions. Certain traditional carrier defences (including broadly drafted force-majeure carve-outs and blanket nautical-fault exclusions) are restricted or modified.
• Mandatory insurance. Carriers operating on routes touching Chinese ports must maintain liability insurance that meets minimum coverage requirements.

The likely practical effect will be that bills of lading incorporating Hague-Visby or Hamburg Rules terms will need to be reviewed to confirm that their liability architecture does not fall below the new Chinese floors. Where it does, the Chinese mandatory standard displaces the contractual term.

Multimodal and Supply-Chain Implications

The revised code extends its reach beyond pure sea carriage. Where a multimodal transport contract includes a sea leg that touches a Chinese port, the maritime-code minimums apply to the sea segment. This has cascading effects for supply chain contracts in China: logistics providers, freight forwarders and 3PL operators who issue through bills of lading or multimodal transport documents must ensure that their contractual terms, and their insurance, comply with the new minimums for the Chinese sea leg.

For industrial supply contracts, particularly those linked to Belt and Road projects, oil and gas infrastructure, or large-scale commodity procurement, flow-down clauses that allocate carriage risk to sub-contractors must be revised. A flow-down clause that passes liability through to a carrier at a level below the Chinese minimum will create a gap: the head-contract holder remains exposed to a claim that the carrier can lawfully refuse to indemnify.

Practical Drafting Changes Sellers and Shippers Must Make

In light of the maritime code 2026 China reforms, four immediate drafting actions are necessary:

1. Audit existing bill-of-lading terms to confirm they meet or exceed the new Chinese liability floors.
2. Add a “Chinese mandatory law” savings clause that expressly provides for the application of Chinese mandatory rules where the contract touches a Chinese port, without disturbing the chosen governing law for other purposes.
3. Review force-majeure and exclusion clauses to ensure they do not conflict with the restricted carrier defences under the revised code.
4. Update insurance requirements in charter-parties and volume contracts to reference the new mandatory minimums.

Arbitration Law 2026: What Changed for Seat, Institution and Arbitrability

Key Legislative Changes

The revised Arbitration Law, effective 1 March 2026, addresses several long-standing concerns raised by foreign parties engaged in disputes connected to China. Academic and institutional analysis identifies the following headline changes:

• Clause validity. The law clarifies the requirements for a valid arbitration clause, including the need to specify an arbitration institution or provide a clear method for determining one. Ad hoc arbitration remains limited, though the revised law opens a narrow pathway for ad hoc proceedings in specific pilot zones.
• Institutional preference. The revisions reinforce the role of recognised arbitration institutions (CIETAC, SHIAC, BAC, and regional maritime commissions) and introduce clearer rules on how courts should interpret ambiguous institutional designations.
• Interim measures. Chinese courts now have an expanded statutory basis for granting interim preservation measures in support of both domestic and foreign-seated arbitrations, provided the applicant demonstrates a connection to China (assets, performance, or parties within the jurisdiction).
• Arbitrator appointment. New provisions allow greater flexibility in appointing non-Chinese nationals as arbitrators in disputes administered by Chinese institutions, though institutional panel requirements still apply.

Arbitration Seat China: When China Is Treated as the Seat

The seat question is critical for contracts of carriage enforcement. Under the revised law, where the arbitration agreement designates a Chinese city as the place of arbitration and names a Chinese institution, China will be treated as the seat. The practical consequence is that Chinese procedural law governs the arbitration, Chinese courts exercise supervisory jurisdiction, and any challenge to the award is heard by a Chinese court.

Industry observers expect that the expanded interim-measures framework will make a China seat more attractive for parties who need rapid preservation of ship-related assets or cargo within Chinese territory. Conversely, parties who prefer a neutral seat should be aware that choosing a foreign seat does not eliminate the need for Chinese court assistance where enforcement targets are located in China.

Drafting Recommendations for Arbitration Clauses

To ensure enforceability, arbitration clauses in contracts touching Chinese ports should:

• Name the institution explicitly, avoid vague references such as “arbitration in China” without specifying CIETAC, SHIAC or another recognised body.
• Specify the seat and the venue, distinguish between the juridical seat (which determines supervisory court jurisdiction) and the physical hearing venue.
• Include a China interim-relief carve-out, expressly permit either party to apply to Chinese courts for interim measures without waiving the arbitration agreement.

Decision Tree: Choosing Governing Law and Seat for Contracts Touching Chinese Ports

The interplay between mandatory maritime rules and choice of law in China requires a structured decision process. The following framework helps in-house counsel determine the optimal combination of governing law and arbitration seat.

Sample Clause Alternatives

• Variant A, Chinese law, Chinese seat. “This Contract shall be governed by the laws of the People’s Republic of China. Any dispute shall be submitted to CIETAC for arbitration in [Tianjin/Shanghai], in accordance with its rules in effect at the time of filing.” Best for: contracts with predominant Chinese performance and Chinese-located enforcement targets.
• Variant B, Foreign law, neutral seat, China enforcement clause. “This Contract shall be governed by English law. Disputes shall be referred to arbitration under SIAC Rules, seated in Singapore. Notwithstanding the foregoing, either party may apply to any competent court in the PRC for interim measures of protection, including ship arrest and property preservation, without waiving this arbitration agreement.” Best for: international commodity trades where parties prefer a neutral forum but need Chinese enforcement capability.
• Variant C, Foreign law, China seat hybrid. “This Contract shall be governed by English law. Disputes shall be referred to CIETAC for arbitration in Shanghai. The tribunal shall apply English law as the substantive governing law.” Best for: parties who want Chinese supervisory-court support and efficient local enforcement while maintaining a familiar substantive law.

Enforcement Playbook: Arrest, Interim Relief and Enforcing Foreign Awards and Judgments in China

Pre-Action Preservation Steps in China

Contracts of carriage enforcement often depends on speed. The revised Maritime Code preserves and expands China’s ship-arrest mechanism, allowing a claimant to apply for the arrest of a vessel in a Chinese port before or during arbitral or court proceedings. The practical steps for claims handlers are:

1. Identify the target vessel and port. Confirm the vessel’s schedule, flag state and registered owner. Verify the port of call in China where arrest will be applied for.
2. Prepare the application. File with the maritime court with jurisdiction over the port. Include the underlying claim, evidence of the maritime lien or contractual claim, and the proposed security amount.
3. Post security for wrongful arrest. Chinese maritime courts require the applicant to provide counter-security (typically a bank guarantee or P&I club letter) to cover the respondent’s losses if the arrest is later found to be wrongful.
4. Serve the order. Once granted, the court issues the arrest order, which is served on the harbour master and the vessel’s master.
5. Commence substantive proceedings. The applicant must commence arbitration or litigation within the deadline set by the court (typically 30 days) or the arrest lapses.

Enforcing Foreign Arbitral Awards in China

To enforce a foreign arbitral award in China, the applicant relies on the New York Convention (to which China is a party, subject to the reciprocity and commercial reservations). The process requires filing with the intermediate people’s court at the place of the respondent’s domicile or where the respondent’s assets are located. Key requirements include:

• A valid arbitration clause. The clause must satisfy the validity requirements of both the law of the seat and Chinese law. Guidance from the EU SME Centre confirms that ambiguous or defective clauses remain the single most common ground for refusal.
• Authenticated award and agreement. The original award and arbitration agreement (or certified copies), with Chinese translations notarised and authenticated.
• No grounds for refusal. The respondent bears the burden of proving grounds for refusal (e.g., lack of due process, excess of jurisdiction, public policy). Chinese courts apply the “reporting system” for refusal: a lower court that intends to refuse enforcement must report to the Supreme People’s Court for approval.

Early indications suggest that the revised Arbitration Law’s clarified clause-validity rules will reduce, but not eliminate, disputes over whether an arbitration agreement is enforceable in China.

Enforcing Foreign Judgments

Enforcement of foreign court judgments in China remains more difficult than enforcement of arbitral awards. China does not have a comprehensive treaty network for reciprocal judgment enforcement. In practice, parties with enforcement targets in China should consider arbitration as the primary dispute-resolution mechanism, given the New York Convention framework. Where a foreign judgment is the only option, strategic alternatives include re-litigation of the claim in a Chinese court using the foreign judgment as evidence, or negotiated set-off arrangements.

Practical Timeline and Cost Expectations

Based on regional enforcement practice in ports such as Tianjin and Tangshan, the following timelines are typical:

• Ship arrest. Application to order: 48–72 hours (urgent applications can be processed within 24 hours).
• Property preservation (non-vessel assets). Application to order: 5–15 working days.
• New York Convention enforcement. Filing to decision: 6–18 months, depending on complexity and whether the respondent raises objections.
• Costs. Court filing fees are modest by international standards. The principal expense is local counsel fees and the counter-security requirement for arrest, which can range from 10% to 30% of the claim value depending on the court.

Common Contract Drafting Changes and Model Clauses

The following model clauses address the most frequent gaps identified in contracts of carriage and supply chain contracts in China after the 2026 reforms. Each clause includes a usage note and risk warning.

• Chinese Mandatory Law Savings Clause. “To the extent that mandatory provisions of the laws of the People’s Republic of China apply to this contract by reason of loading or discharge at a Chinese port, such provisions shall prevail over any inconsistent term of this contract.” Use when: the contract is governed by a foreign law but touches a Chinese port. Risk note: without this clause, the contract may be partially unenforceable in China without the parties’ awareness.
• Expedited Interim Relief Clause. “Nothing in this arbitration agreement shall prevent either party from applying to any court of competent jurisdiction, including the maritime courts of the PRC, for interim or conservatory measures.” Use when: enforcement targets or vessels are likely to be in China. Risk note: omitting this clause may delay preservation applications.
• Carrier Liability Floor Acknowledgement. “The parties acknowledge that the carrier’s liability under this contract shall not be less than the minimum prescribed by the Maritime Code of the PRC as in force at the date of shipment.” Use when: updating bills of lading or charter-party riders for post-1 May 2026 shipments.
• Supply-Chain Flow-Down Clause. “The Contractor shall ensure that all sub-contracts for carriage by sea include terms no less favourable to the cargo interest than those required by the mandatory provisions of the PRC Maritime Code.” Use when: head contracts for large infrastructure or commodity supply chains.
• Arbitration Institution Specification. “Any dispute arising out of or in connection with this contract shall be referred to and finally resolved by arbitration administered by [CIETAC / SHIAC / BAC], in accordance with its arbitration rules.” Use when: any contract where Chinese courts may be asked to enforce the award. Risk note: failing to name a specific institution remains the leading ground for clause invalidity in China.
• Local Counsel Appointment Clause. “Each party shall appoint local counsel admitted to practise in the PRC within [14] days of the commencement of any proceedings or enforcement action in China.” Use when: multi-jurisdictional contracts where enforcement in China is foreseeable.

Lessons from Practice: Anonymised Case Examples

The following anonymised examples illustrate how the interplay between contract drafting and Chinese enforcement rules has played out in recent maritime and industrial disputes.

Example 1, Oil pipeline equipment supply. A European equipment supplier contracted with a Chinese EPC contractor for supply and delivery of pipeline components to a northern Chinese port. The contract was governed by Swiss law, with ICC arbitration seated in Zurich. When a payment dispute arose, the supplier obtained an ICC award but discovered that the contractor’s only attachable assets were in Tianjin. Enforcement took over 14 months because the arbitration clause did not name a specific institution recognised under Chinese law guidelines, and the respondent argued the clause was defective. The lesson: even with a foreign seat, the clause must be drafted to withstand Chinese validity scrutiny at the enforcement stage.

Example 2, Marine seismic survey charter. A charter-party for a seismic survey vessel operating out of a Chinese port included a broadly drafted force-majeure exclusion that would now conflict with the revised Maritime Code’s restricted carrier defences. When weather-related delays occurred, the charterer invoked the clause to withhold hire. Under the post-1 May 2026 regime, this type of exclusion is likely to be unenforceable in Chinese proceedings. The lesson: review legacy charter-party terms against the new mandatory standards before the next fixture.

Example 3, Commodity trading enforcement. A Singapore-based commodity trader arrested a vessel at a Chinese port to secure a cargo-damage claim. The arrest was executed within 36 hours, but the trader had not posted adequate counter-security, and the court released the vessel after the shipowner challenged the security level. The trader had to re-apply, losing critical time. The lesson: pre-arrange P&I club letters of undertaking to the appropriate value before filing arrest applications.

Checklist: What In-House Counsel Must Do in the Next 90 Days

The following actions should be completed within 90 days of the 1 May 2026 effective date of the revised Maritime Code:

1. Contract audit. Identify all active contracts of carriage, charter-parties and supply-chain agreements where loading or discharge occurs at a Chinese port.
2. Clause review. Check each contract’s governing-law, arbitration, force-majeure and liability clauses against the new mandatory minimums.
3. Arbitration clause validity. Confirm that every arbitration clause names a specific institution, specifies a seat and includes an interim-relief carve-out.
4. Insurance check. Verify that P&I and cargo insurance policies meet the new mandatory coverage floors.
5. Flow-down compliance. Ensure sub-contracts and logistics agreements include compliant flow-down provisions.
6. Escalation matrix. Establish a dispute-escalation protocol that identifies local counsel in key Chinese port cities and pre-approves counter-security arrangements for ship arrest.
7. Training. Brief commercial and claims teams on the new rules, with emphasis on the distinction between waivable and unwaivable terms.
8. Enforcement playbook. Prepare or update the company’s enforcement playbook for China, covering arrest procedures, New York Convention applications and asset-tracing protocols.
