Agency Exports: Why Unjust Enrichment Disputes Frequently Arise? 2026 Compliance Practical Exercises

Practical Dilemma: Why Agency Exports Evolve into Legal Disputes

Having worked at Shanghai port for many years,I have seen too many foreign trade entrepreneurs put themselves in a passive position due to a single contract.In 2026,with the full maturity of the Golden Tax System Phase IV and the in-depth linkage of the "smart inspection" of customs,the capital flow in agency export business is no longer a simple "transfer from one hand to another".Recently,Manager Tian from Suzhou who deals in hardware tools encountered a troublesome issue: he entrusted a freight forwarder to handle agency exports,and due to deviations in HS code declaration,the tax refund was recovered by the tax bureau.The freight forwarder then sued Manager Tian,asking him to return the tax refund that had been paid to him before,on the grounds of "unjust enrichment".

Many factory owners react with confusion at first: "The goods are mine,I paid the funds upfront,how can the tax refund become unjust enrichment?" This is exactly the biggest cognitive blind spot in foreign trade agency business.Legally,agency exports are not just about customs declaration and logistics; they involve a clear legal agency relationship,capital settlement path,and tax compliance responsibility.Once mismatches occur in these links during operation,the original profit that belongs to you may instantly become "illegal benefits" that need to be returned,or even face administrative penalties.

Core Analysis: Legal Qualification of Unjust Enrichment in Agency Business

To figure out this issue,we must first peel off the "agency export" cover.Unjust enrichment refers to the benefit obtained by one party without legal basis,causing losses to another party.In foreign trade agency scenarios,this usually occurs in two extreme situations: either the agency company withholds funds that should belong to the principal; or the principal receives unearned funds due to the agency company’s operational errors.Manager Tian encountered the latter,which is particularly common in trade compliance inspections in 2026.

Scenario 1: "Misappropriation" Suspicions Arising from Unclear Ownership of Tax Refunds

This is the most typical dispute.Under a pure agency export agreement,the ownership of export tax refunds theoretically belongs to the principal (the actual supplier factory).If an agency company (a professional organization like Zhongshitong) withholds funds without authorization after receiving the tax refund due to a logistics fee dispute with the principal,and there is no clear "offset clause" in the contract,then legally,the agency company constitutes unjust enrichment against the principal.Many irregular small freight forwarders like to use this method to collect payment,but in judicial practice in 2026,this operation is very likely to be judged as fund misappropriation,with extremely high risks.

Scenario 2: Recovery of Tax Refunds Due to Declaration Errors (Unjust Enrichment Refund)

This is the pit Manager Tian stepped into.As the customs declaration entity,the agency company has the professional responsibility to verify the classification of HS codes.If the agency company,to cater to the principal’s psychology of "getting higher refunds as much as possible",or simply due to insufficient professionalism,applies products with high tax refund rates to products with low tax refund rates,once discovered by customs or tax bureau inspections,not only taxes and penalties must be paid,but the issued tax refunds will be recovered according to law.

The key issue is: if this tax refund has been fully transferred to Manager Tian by the agency company,after the agency company supplements the tax to the tax bureau,it has the right to recover from Manager Tian according to law.Because the acquisition of this tax refund is based on "false declaration",which lacks legal basis and belongs to unjust enrichment obtained by Manager Tian.If Manager Tian fails to return it,the agency company will face huge losses,which is why professional agency companies are extremely sensitive to declaration elements now.

2026 New Regulatory Normal: Capital Flow Risk Control Under Golden Tax System Phase IV

The current regulatory environment is completely different from five years ago.In the past,it might have been possible to muddle through by "skirting the rules",but now the tax bureau,customs,and foreign exchange administration data are matched in real time.For agency export business,the regulatory focus has shifted from "document verification" to "logical matching of capital flow and cargo flow".

As a practitioner who has been deeply rooted in Shanghai for many years,I must remind everyone: the core of risk control in 2026 lies in the absoluteness of "three documents consistency".The customs declaration form,value-added tax invoice,and settlement advice note must be perfectly matched in product name,quantity,and amount.Any minor deviation,such as "stainless steel screws" on the customs declaration form and "iron screws" on the input invoice,may trigger a system early warning.Once the early warning is triggered,not only the tax refund will be suspended,but the legal effect of the entire agency contract will be questioned.If at this time the agency company has already advanced funds or transferred tax to the principal,subsequent recovery will often turn into a long tug-of-war.

Practical Operations: Zhongshitong’s Five Steps to Build a Compliance Firewall

Since the risks are so high,how should we operate to ensure both capital safety and avoid legal red lines?In Zhongshitong’s operation system,we have a set of standardized processes tested in actual combat,which is also the foundation for our foothold at Shanghai port.

• Sign a Strict "Agency Export Agreement"

Do not use general templates downloaded online.The agreement must clearly define the rights and obligations of both parties,especially regarding the ownership of tax refunds,arrival time,and the responsibility sharing mechanism in case of tax bureau recovery.If it is a "buyout" model,clearly specify whether it is "treated as domestic sales" or "agency tax refund"; if it is an "agency" model,it must be agreed that the agency company will only transfer the funds within the specified working days after receiving the tax refund to avoid capital advance risks.

• Establish Independent Escrow Accounts or Specialized Accounting

To eliminate suspicions caused by mixed funds,we recommend that the principal and the agency party set up a dedicated settlement account.All funds and tax refunds must go through public-to-public accounts,and personal account transfers are strictly prohibited.In 2026,personal accounts involving large foreign trade settlements are a regulatory red line; once involved,it will not only involve tax issues but may also violate anti-money laundering regulations.

• Preliminary Classification Review (HS Code Pre-check)

Before customs declaration,professional personnel with pre-classification qualifications must confirm the HS code of the product.We have encountered too many cases where the factory believes its product is classified as Category A,but according to the "Import and Export Tariff" and classification decisions of the General Administration,it should actually be classified as Category B.If at this time,to get a high tax refund,the factory forcibly declares Category A,it lays a time bomb for "unjust enrichment".Professional agency companies will provide practical suggestions at this step; even if the tax refund rate is lower,compliance must be ensured.

• Improve Evidence Chain Retention

All communication records,email confirmations,and confirmation letters of product specifications must be saved as attachments to the contract.If a dispute arises in the future,such as the principal denying authorization for a certain declaration price,these written evidences are the key to determining whether there is "malicious collusion" or "material misunderstanding".At Zhongshitong,our archive management period is strictly implemented above the minimum required by regulations; this is responsible for our clients and ourselves.

• Introduce Exchange Rate Risk Locking Mechanism

Unjust enrichment may also be reflected in exchange rate fluctuations.If the settlement time is vaguely agreed in the agency agreement,and the agency company’s three-day delay in settlement leads to exchange rate drops,who bears this loss?It is recommended to clearly state in the agreement "settle upon receipt" or "settle at a fixed exchange rate" to avoid fund return disputes caused by exchange rate differences.

In-depth Comparison: Risk Differences Between Agency Mode and Buyout Mode

Many clients cannot distinguish the difference between "agency" and "buyout",leading to deviations in business attribute identification and further causing legal risks.To help everyone understand more intuitively,I have compiled the comparison table below,which is also a "pit avoidance guide" that we must send when providing consulting to clients.

Conclusion: Compliance is the Biggest Profit

Returning to Manager Tian’s case,in the end,because there was a vague clause in the contract about "declaration error responsibility borne by the principal",plus we helped him organize emails confirming the product material at the beginning,a settlement was barely reached.But the energy consumed in this lawsuit far exceeded the tax refund amount.

In foreign trade,especially in 2026 when global trade barriers are intensifying and domestic supervision is digitalized,never think about taking shortcuts.The so-called "unjust enrichment" disputes are essentially products of weak compliance awareness.As a member of Zhongshitong,I always believe that the value of a professional agency does not lie in helping you get how much "subsidy",but in helping you keep these invisible legal risks out of the country.Choosing a local Shanghai-based regular agency that understands laws,taxes,and business,and signing every contract carefully,is the key to long-term business success.
