At 18:40, the day before payment is due, the manager of a Chinese factory sends new bank details via WeChat:
“Please pay to our Hong Kong agent. Same invoice.”
The contract and invoice identify a Shenzhen company as the seller. The CNY 100,000 is now to be received by a Hong Kong company that has never appeared in the documents before. Another message follows almost immediately: “You can write services.”
A different recipient does not, by itself, mean that the arrangement is automatically impermissible. But one message from a manager is not enough to determine the legal effect of the transfer. Before payment, it is necessary to establish the capacity in which the Hong Kong company is acting, who is authorised to change the seller’s payment instructions, which obligation the transfer is intended to discharge, and exactly what event will cause the buyer’s debt to be treated as paid.
Transfers that look identical on a bank screen may reflect very different legal arrangements. The seller may remain unchanged and merely instruct the buyer to pay the price due to it to a third party. The buyer may appoint its own payment intermediary, which first receives the money from the buyer and then remits it to the seller. The Hong Kong company may become a party to a new sale. Finally, the original seller may assign its monetary claim against the buyer to another person.
These arrangements cannot be collapsed into the single word agent. They have different documentary foundations, different moments of performance, and different consequences if the intermediary retains a fee, a correspondent bank deducts charges, or the money never reaches the factory at all.
The company names, invoice number and amounts used in this example are illustrative.
If the factory remains the seller and itself designates the Hong Kong company as the recipient, the main issue is not whether that company exists, but whether the seller recognises crediting the money to the designated account as performance of the buyer’s payment obligation. That result should follow from the contract, an addendum, or a valid payment instruction from the seller issued in a form permitted by the contract and the applicable law.
The wording should connect the specific contract, invoice, amount, currency, recipient and moment of performance. In a disputed situation, it is not enough to state that the company is “authorised to receive payment”. The parties should separately identify the banking event that discharges the debt. If they intend the seller to bear the risk of any onward remittance to the factory after the Hong Kong company has received the money, that allocation should be stated expressly.
For example:
“The Buyer’s payment obligation under Invoice No. 47 shall be deemed fully discharged when CNY 100,000 is credited in full to the designated account of Golden Bridge Trading Limited specified in the Seller’s signed payment instruction. Upon the Buyer’s request, the Seller or Golden Bridge Trading Limited shall provide the receiving bank’s account statement or other bank confirmation showing such credit; alternatively, the Seller may confirm in writing that the designated recipient has received CNY 100,000 and that the full amount has been applied to Invoice No. 47. From that moment, any failure by Golden Bridge Trading Limited to remit all or any part of those funds to the Seller, and any fee retained by it under its arrangements with the Seller, shall be for the Seller’s account and shall not create any outstanding balance payable by the Buyer. In this example, all bank and correspondent-bank charges incurred before the full CNY 100,000 is credited to the designated account are borne by the Buyer, so that the designated account receives CNY 100,000 in full.”
This wording is not a universal rule of law. It is an example of contractual risk allocation. In the example above, bank charges are borne by the buyer; if the parties agree otherwise, that term should be expressly changed rather than left for interpretation after payment. The expression credited in full to the designated account is used here as the event agreed by the parties after which the risk of any further movement of funds from the recipient to the factory passes to the seller. Because the recipient’s account statement will usually not be available to the buyer, the wording also requires the seller or its designated recipient to confirm that the full amount has been credited, or allows the seller to acknowledge in writing that the designated recipient has received the full amount and that it has been fully applied to the specific invoice.
If Russian law governs the obligation, the contractual arrangement should be considered alongside Article 408 of the Russian Civil Code on discharge by due performance, Article 316 of the Russian Civil Code, and paragraph 26 of Resolution No. 54 of the Plenum of the Supreme Court of the Russian Federation dated 22 November 2016. For a non-cash monetary obligation, the Plenum generally links the moment of performance to the crediting of funds to the correspondent account of the bank servicing the creditor; where the debtor and creditor are serviced by the same bank, to the crediting of funds to the creditor’s account. If, however, the seller designates an independent third party as the recipient of payment, the consequences of crediting funds to that person must separately follow from the parties’ agreement and the applicable law. A contractual term providing for full credit to a specified third-party account is therefore an agreed mechanism for the particular transaction, not a direct restatement of paragraph 26.
The intermediary’s own fee must also be distinguished from bank charges arising along the payment route. If Golden Bridge receives the full CNY 100,000 and then retains CNY 2,000 under its arrangements with the seller, that is one situation. If the buyer sends CNY 100,000 but only CNY 99,700 is credited to the designated account because a correspondent bank deducts a charge, that is another. Before payment, the parties should expressly determine whether the full invoice amount must be credited without deduction of bank charges and which party bears those charges. Banking designations such as OUR, SHA or BEN may describe the technical allocation of charges for a particular transfer, but they do not replace a contractual answer to the question of how much must be received in discharge of the obligation. Where Russian law applies, Article 309.2 of the Russian Civil Code on the costs of performance is also relevant; it should not, however, be applied mechanically to every international supply contract.
Where Russian law applies, a debtor may require evidence that performance is being accepted by the creditor itself or by a person authorised by the creditor, unless otherwise follows from the parties’ agreement, usage or the nature of the obligation. This follows from Article 312 of the Russian Civil Code. A letter from the seller naming a new recipient therefore matters principally as evidence that the money is being accepted by a person designated by the creditor. The fact that the recipient exists in a corporate register does not establish that point.
It is also necessary to verify not only the recipient but the person who, on behalf of the seller, changes the payment instructions. Under Russian conflict-of-laws rules, issues of representation are governed by Article 1217.1 of the Russian Civil Code, while the legal capacity of a foreign legal entity, the competence of its governing bodies and other matters relating to its status are governed by the entity’s personal law under Article 1202 of the Russian Civil Code. A corporate email address or the title “sales manager” does not, by itself, establish authority to change the payment recipient. Depending on the circumstances, constitutional documents, a corporate resolution, a power of attorney or other evidence of authority under the law of the relevant jurisdiction may be required.
The position is different where the payment intermediary is chosen by the buyer. In that case, transferring money to the intermediary will not ordinarily mean that the seller has received performance. The buyer instructs a third party to perform its monetary obligation, and the legal effect vis-à-vis the seller arises when performance is made in favour of the seller, unless the parties have expressly agreed otherwise.
Where Russian law applies, Article 313 of the Russian Civil Code permits performance by a third party in the circumstances provided by law and, in particular, where the debtor has entrusted performance to that person. Paragraph 22 of Resolution No. 54 of the Plenum of the Supreme Court of the Russian Federation dated 22 November 2016 further explains that, where the debtor has entrusted performance to a third party, the debtor remains liable to the creditor for that third party’s failure or defective performance unless the law provides otherwise. The seller therefore does not need to turn the buyer’s intermediary into the seller’s own agent merely because payment does not come directly from the buyer’s bank account; however, as a general rule, the risk of defective performance by an intermediary selected by the buyer remains with the buyer. Evidence of performance requires not only documents showing the transfer to the intermediary, but also documents showing the onward payment to the seller and identifying the obligation to which the seller applied the amount received.
This distinction is particularly important where a fee is involved. If the buyer transfers CNY 100,000 to its own payment intermediary, the intermediary retains CNY 2,000 as its fee, and the seller receives CNY 98,000, the first transfer alone does not establish that an invoice for CNY 100,000 has been discharged. The contract with the seller, the buyer’s mandate to the intermediary, the fee terms and the actual settlement all have to be examined.
The third model requires even greater care. The appearance of a Hong Kong company on a new invoice does not, by itself, mean that there has been a “transfer of contract”. Several structures are possible: a tripartite amendment to the original contract, termination of the original transaction and conclusion of a new one, an independent resale of the goods to the Hong Kong company followed by a sale to the Russian buyer, an assignment of the claim only, or a transfer of all rights and obligations under the contract.
If all rights and obligations of a party are in fact transferred under the applicable law, Article 392.3 of the Russian Civil Code applies where Russian law governs, together with the rules on assignment of claims and transfer of debt. But that provision is not a universal explanation for every appearance of a new seller.
Once the legal structure has been identified, the sale itself must be examined: who is obliged to deliver the goods, who is responsible for their quality and short delivery, who bears the commercial risk, with whom the price was agreed, and who appears in the transport, export and other commercial documents. A new payment recipient and a new seller are not the same thing.
The fourth model is an assignment of the monetary claim. In that case, the Hong Kong company becomes not a payment intermediary but a new creditor to the extent of the assigned claim. Under Russian conflict-of-laws rules, the relationship between the new creditor and the debtor, the conditions under which the claim may be asserted against the debtor, and due performance are determined with regard to Article 1216 of the Russian Civil Code. Where Russian law applies to the relevant issues, Article 385 of the Russian Civil Code allows the debtor to withhold performance to the new creditor until evidence of the transfer of the claim is produced, except where notice of the transfer has been received from the original creditor.
A message saying “our agent” therefore cannot simultaneously serve as evidence of representation, transfer of contract and assignment of a claim. The legal structure must be identified first; the documents should then be assembled for that structure.
For a Russia–China supply contract, the form of any amendment to the parties’ arrangements must also be checked separately. Russia and China are parties to the 1980 United Nations Convention on Contracts for the International Sale of Goods. The Convention has applied territorially to Hong Kong since 1 December 2022. Russia also maintains its declaration under Articles 12 and 96 of the Convention. A WeChat message should therefore not automatically be treated as a sufficient form of amendment to a payment term merely because it came from a manager. It is necessary to examine the applicability of the Convention, the law chosen by the parties, the contract’s own provisions on notices and changes of bank details, and the authority of the sender.
Article 57 of the CISG, concerning the place of payment, is also relevant. Unless the parties agree otherwise, the Convention provides rules on where the buyer must pay the price. Merely specifying a new bank account does not always mean that the parties have changed the place of performance. Article 57 does not, however, determine whether the creditor has been replaced: assignment of claims, representation and transfer of contract are governed separately by the applicable domestic and conflict-of-laws rules. The extension of the CISG to Hong Kong has independent significance where the Hong Kong company is itself a party to the international sale contract. If it merely receives money on behalf of the Shenzhen seller, that fact alone does not bring questions of representation or assignment within the Convention. A payment instruction should therefore answer not only “which account should be paid?” but also “what legal effect follows once the money is credited to that account?”
If the contract expressly provides that a change of bank details takes effect only after a signed notice is received at a specified email address, a messenger message should not replace that procedure. If the contract allows another method of agreement, that method should be assessed on its own terms. There is no universal rule that “WeChat has no legal force”, but there is equally no universal rule that “a manager’s message is sufficient”.
When checking a Hong Kong recipient, the Companies Registry is useful. Following full implementation of the Unique Business Identifier on 27 December 2023, the Business Registration Number — the first eight digits of the Business Registration Certificate number — is used as the identification number of registered companies instead of the former Company Registration Number. The register can confirm the company’s existence and registration particulars. It does not establish that a particular bank account belongs to that company, that a particular employee is authorised to change payment terms, or that receipt of money by that company discharges the debt owed to the factory.
Independent verification of changed bank details should therefore be made through a previously known communication channel with the seller. If the new details appeared only in a new message, they should not be treated as verified merely because the reply to a follow-up question came through the same conversation. Otherwise, the source of the change is effectively authenticating itself.
Customs value is a separate issue. Here it is particularly dangerous to confuse the actual movement of funds with the price of the goods.
Paragraph 3 of Article 39 of the EAEU Customs Code defines the price actually paid or payable as the total amount of all payments made or to be made by the buyer for the imported goods directly to the seller or to another person for the benefit of the seller. Therefore, if the seller instructs the buyer to transfer CNY 100,000 to a designated recipient and that payment fully discharges the invoice price, a subsequent retention of CNY 2,000 within the relationship between the seller and its recipient does not, by itself, mean that the price of the goods for customs valuation purposes has become CNY 98,000.
If the buyer separately pays for the services of its own intermediary, the analysis should proceed in sequence. First, it is necessary to determine whether the relevant amount forms part of the price actually paid or payable under Article 39 of the EAEU Customs Code. This requires examining whether the intermediary agreement forms part of the set of agreements under which the goods were sold for export to the customs territory of the Union, and whether the buyer could have purchased the goods independently of the intermediary’s services. This approach is reflected, in particular, in the Rules for applying the transaction value method approved by Decision No. 283 of the Board of the Eurasian Economic Commission dated 20 December 2012, and in Letter No. 27-01-21/106988 of the Russian Ministry of Finance dated 1 November 2024 concerning payment-agent remuneration. The Ministry of Finance letter is not a regulatory legal act, but it shows the Ministry’s position on the classification of such expenses.
If the amount does not form part of the price actually paid or payable, the next step is to determine whether it is an additional charge under Article 40 of the EAEU Customs Code.
Subparagraph (a) of subparagraph 1 of paragraph 1 of Article 40 of the EAEU Customs Code provides for adding commissions and brokerage fees to the price to the extent that such costs are incurred or payable by the buyer and are not already included in the price of the goods. At the same time, the provision excludes buying commissions paid by the buyer to its agent for representing the buyer’s interests outside the customs territory of the Union in connection with the purchase of the imported goods.
Before that exclusion can be applied, however, it is necessary to establish whether the particular service is of the type of intermediary activity covered by Article 40 at all. A technical payment agent does not automatically become a buying agent merely because the word agent appears in the agreement.
Decision No. 112 of the Board of the Eurasian Economic Commission dated 15 July 2014 operates within that analysis: it requires the substance of the relationship and the intermediary’s actual functions to be examined rather than relying only on the title of the agreement or the label attached to the payment. Terms such as agent fee, payment fee and buying commission do not, by themselves, determine the customs outcome.
That boundary is illustrated by case No. A41-42056/2025. The Commercial Court of the Moscow Region, the appellate court and subsequently the Commercial Court of the Moscow District, in Resolution No. F05-1289/2026 dated 11 March 2026, proceeded on the basis that the payment agent engaged by the buyer performed the technical function of transferring funds. Its involvement was not a mandatory condition of the sale, and the agent did not participate in finding the seller, negotiating the purchase terms or carrying out other activities connected with the purchase and sale of the goods. On the facts established by the courts, the remuneration of that payment agent was not included in the customs value.
In a comparable factual model, the courts also treated the payment intermediary’s services as technical in case No. A56-37429/2025. Resolution No. F07-14247/2025 of the Commercial Court of the North-Western District dated 5 February 2026 left the conclusions of the lower courts unchanged. The dispute arose from administrative liability proceedings, and the factual structure involved an agreement on the transfer of debt, which the courts treated as an optional settlement mechanism rather than a mandatory condition of the sale. The conclusions of that case therefore cannot be transferred automatically to every agency arrangement.
The significance of both cases lies in their limits. They do not establish a general rule that every payment-agent fee is excluded from customs value. In each case, it is necessary to determine who selected the intermediary, what functions it performed, whether its involvement formed part of the conditions of sale, and what precisely the remuneration was paid for.
Banking control does not replace this legal analysis. Article 23 of Federal Law No. 173-FZ allows currency-control authorities and agents to request documents and information connected with foreign-exchange transactions. For transactions falling within Bank of Russia Instruction No. 181-I dated 16 August 2017, it is necessary to determine who the payer is, who the recipient is, whether the contract is registered for currency-control purposes, and which particular third-party settlement model is being used.
The amendments introduced by Bank of Russia Directive No. 7333-U dated 31 March 2026 do not create a single general rule for every foreign payment intermediary, but they expressly address settlements involving third parties. Section I(1) was added to the contract currency-control statement to record information on a third party by whom, or in whose favour, a payment or other performance under the contract has been made. Column 3a of Section II is completed for settlements under a contract involving third parties, including a situation where a party to the contract makes a payment in favour of a third party. This is directly relevant to a model in which a Russian buyer transfers money to a Hong Kong company designated by the seller.
The amended paragraph 10.5 of Instruction No. 181-I concerns a separate situation: settlements by a third-party resident through an account with a non-resident bank or another financial-market organisation. Directive No. 7333-U must therefore be applied to the particular settlement structure. The rules of paragraph 10.5 cannot automatically be extended to a foreign recipient, but the new rules requiring third parties to be reflected in the currency-control statement cannot be ignored either.
The bank should be given an accurate description of the actual transaction. If the transfer is payment for goods under a particular contract and invoice, using consulting services as the payment purpose merely because a foreign manager suggested it creates a contradiction between the economic substance of the payment and the supporting documents. That wording does not turn payment for goods into payment for services and may complicate currency and banking control.
In addition to currency control, the bank performs its obligations under Federal Law No. 115-FZ and applies its own internal-control procedures. A new foreign recipient does not automatically require the transaction to be rejected, but the bank may request documents and explanations in the circumstances provided by law and its internal rules.
Even a complete contractual and banking file does not guarantee that a particular transfer can be made in the chosen currency and through the chosen route. On the date of the transaction, it is also necessary to check the special economic measures then in force, the status of the parties and banks, any restrictions affecting the correspondent-banking route, and the actual ability to settle with the particular non-resident. These circumstances change over time and should not be replaced by a general conclusion that the agency arrangement is permissible.
If sufficient evidence of the new recipient’s authority has not been obtained by the payment date, it is not enough simply to say, “we have suspended payment”. The seller’s notice does not, by itself, extend the payment deadline. It is necessary to determine whether the contract or the applicable law permits payment to be withheld until the proper recipient is confirmed, or whether the payment deadline should instead be separately amended by agreement.
Where Russian law applies, Article 312 of the Russian Civil Code protects a debtor that requires evidence that performance is being accepted by the proper person. Paragraph 18 of Resolution No. 54 of the Plenum of the Supreme Court of the Russian Federation dated 22 November 2016 explains the consequences of a debtor refusing to perform until such evidence is produced. But this rule should not be turned into a right to demand an unlimited set of documents once the relevant authority has already been properly established.
If the money has already been transferred, documents should not be backdated. The original correspondence, invoice versions, payment orders, bank messages and intermediary documents should be preserved in the form in which they existed at the time of payment.
Article 183 of the Russian Civil Code concerns a transaction entered into by an unauthorised person and its subsequent approval by the represented person. It does not turn every later letter from the seller into an “approval”. Depending on the facts, a later document may acknowledge acceptance of performance, amend the contract, record that no balance remains due, or approve specific actions of a representative. Its legal character should correspond to what actually occurred.
Accordingly, where payment has already been made, the appropriate document should bear the current date and expressly describe the transaction that has taken place. It should not create the appearance that a payment instruction existed before the transfer if it did not.
In the original scenario, the buyer needs a short but legally precise response from the supplier. If the recipient has been designated by the seller, the message may read:
“Please confirm that Golden Bridge Trading Limited is authorised by the Seller to receive CNY 100,000 in payment of Invoice No. 47. Please confirm that the Buyer’s payment obligation under Invoice No. 47 will be fully discharged when CNY 100,000 is credited in full to the designated account specified in the Seller’s signed payment instruction, with no balance remaining payable by the Buyer after such credit. Any fee retained by Golden Bridge Trading Limited under its arrangements with the Seller shall be borne by the Seller. Please confirm which party bears all bank and correspondent bank charges before the full CNY 100,000 is credited to the designated account, and send the signed payment instruction through the notice channel specified in the contract.”
If the payment intermediary was chosen by the buyer, the question to the seller is different: will the seller recognise a payment received from that third party as performance of the particular invoice? The buyer should then obtain from its own intermediary evidence of the actual onward payment to the seller.
If the seller says that the claim has been assigned, confirmation of agency authority does not solve the problem at all. The new creditor, the scope of the assigned claim and the consequences of the notice must be established.
If the Hong Kong company is participating as a new seller, the legal basis for changing the contractual structure must first be determined; changing the bank details alone is not enough.
The word agent answers none of these questions. Before payment, four matters should be settled: who is legally receiving the money, which obligation the payment discharges, when that obligation is treated as performed, and which party bears the intermediary’s fee and bank charges. Once those answers are documented, the risk that payment to a third party will not be recognised as discharging the particular invoice is materially reduced. Contractual documents do not, however, eliminate the separate banking, compliance and operational risks that must be checked independently. If the legal structure itself remains undefined, even a transfer successfully processed by the bank may leave the buyer facing the same invoice and a fresh demand for payment.
