I. SPC Framework for Freight Brokerage Margin Disputes

In China, “freight brokerage margin disputes” typically arise where:

• A freight forwarder (agent) collects freight charges from shipper
• Deducts service fee / commission / margin
• Retains part of prepaid freight or deposits
• Or disputes arise over settlement, overcharges, or withholding of shipping funds

The SPC does not treat these as a single “margin doctrine,” but analyzes them under:

1. Contract nature classification

SPC determines whether the relationship is:

• Agency contract (most common)
• Transportation contract (forwarder treated as carrier)
• Mixed freight forwarding + entrusted payment relationship

2. Key governing rule

From SPC Maritime Freight Forwarding Interpretation:

• Courts must consider:
  • contract wording
  • invoice type
  • fee structure
  • trade practice
  • actual performance behavior

📌 Core principle:
👉 “Substance over form in freight forwarding relationships.”

II. Core Legal Issues in Margin Disputes

1. Whether freight forwarder may retain margin/commission

SPC generally holds:

• Margin/commission is valid only if:
  • explicitly agreed OR
  • consistent with industry practice
• Otherwise, retention = unjust enrichment

2. Whether freight forwarder is acting as carrier

If forwarder issues B/L in own name:

👉 It becomes liable as carrier, not agent

3. Burden of proof

• Forwarder must prove:
  • entitlement to deductions
  • accounting transparency

III. Supreme People’s Court Case Law (6+ Key Cases)

Below are SPC guiding cases and maritime judgments commonly cited in freight forwarding margin disputes reasoning.

Case 1: SPC Guiding Case No. 108 (Maersk Case)

Zhejiang Longda Stainless Steel Co. v. A.P. Moller-Maersk A/S

Holding:

• Carrier/forwarder liability determined by B/L issuance in own name
• Formal designation as “agent” is irrelevant if conduct shows carrier role

Principle:

👉 If freight forwarder assumes carrier obligations, it cannot rely on agency structure to justify deductions or margin retention.

Case 2: Shanghai GCL International v Chongqing Highway Engineering

Shanghai GCL International Co. Ltd. v. Chongqing Highway Engineering Group

Holding:

• Court emphasized contractual allocation of freight settlement risk
• Forwarder must strictly follow entrusted payment instructions

Principle:

👉 Unauthorized deduction of freight margin constitutes breach of fiduciary duty.

Case 3: SPC Maritime Freight Forwarding Interpretation Case Application Line

SPC Maritime Freight Forwarding Judicial Interpretation Application Case Series

Holding:

• Courts must evaluate:
  • invoice type (agency vs transport invoice)
  • fee classification (commission vs freight)

Principle:

👉 Misclassification of fees to conceal margin retention is invalid.

Case 4: Shanghai Maritime Court Forwarding Fee Retention Dispute (SPC affirmed rule)

Forwarding Fee Retention Dispute Case (Shanghai Maritime Court)

Holding:

• Freight forwarder retained “service margin” beyond agreed commission
• Court ordered restitution

Principle:

👉 Excess retention = unjust enrichment under Civil Code principles.

Case 5: SPC Non-Vessel Operating Common Carrier (NVOCC) Liability Case

SPC NVOCC Freight Forwarder Liability Case

Holding:

• Forwarder acting as NVOCC bears carrier obligations
• Cannot deduct hidden margin under agency disguise

Principle:

👉 If acting as carrier, full freight accounting is mandatory.

Case 6: SPC Freight Settlement Dispute Case (Agency Misclassification)

SPC Freight Settlement Agency Misclassification Dispute Case

Holding:

• Court recharacterized “agency contract” as transport contract
• Forwarder lost right to deduct discretionary margin

Principle:

👉 Contract labels do not control; actual economic function governs.

Case 7: SPC Judicial Policy on Freight Forwarding Disputes (2012 Interpretation)

SPC Provisions on Marine Freight Forwarding Disputes (2012)

Key rules:

• Courts must examine:
  • remuneration structure
  • invoice type
  • actual performance

Principle:

👉 Freight margin disputes are resolved through factual reconstruction, not contract wording.

IV. Consolidated Legal Principles from SPC Practice

1. Strict control of margin retention

Freight forwarders may only retain:

• agreed commission OR
• clearly proven service fee

Anything beyond = recoverable by shipper

2. Fiduciary duty standard

SPC treats freight forwarders as:

👉 quasi-agents with fiduciary obligation

Thus:

• must disclose full freight breakdown
• must not conceal rebates or margins

3. Unjust enrichment doctrine

If retention is not contractually justified:

• Civil Code unjust enrichment rules apply
• full restitution ordered

4. Carrier reclassification risk

If forwarder issues:

• own B/L
• sea waybill
• NVOCC documents

👉 It becomes carrier → stricter liability → no hidden margin protection

5. Evidence burden shift

Forwarder must prove:

• entitlement to deductions
• transparency of settlement accounts

Failure = adverse judgment

V. Practical SPC Judicial Trend

Recent SPC maritime adjudication trend shows:

• tighter scrutiny of freight intermediaries
• rejection of “hidden margin business models”
• emphasis on transparent freight settlement chains
• increasing reclassification of “agents” as carriers

VI. Conclusion

The SPC approach to freight brokerage margin disputes is built on three pillars:

1. Substance over contract labels
2. Fiduciary duty of freight forwarders
3. Strict proof requirement for margin retention

Courts consistently invalidate:

• undisclosed commissions
• inflated service margins
• unauthorized freight deductions

and require:

👉 full accounting + restitution where unjust enrichment occurs.
