The declaration is registered, but the goods have not been released. Customs asks why the payment differs from the invoice, what justified the seller’s discount and how transport costs were calculated. Only hours remain before the release period expires. The supplier is in another time zone, accounting is downloading bank records, logistics is sending forwarder invoices, and the customs representative suggests submitting everything collected so far.
The company rushes to meet the deadline. A hastily assembled archive may give customs more questions: one payment covers several shipments, the price list belongs to another period, the transport invoice has no breakdown by route segment, and correspondence conflicts with the final invoice. There are plenty of documents but no consistent account of the transaction.

A request is not yet an adjustment
A request does not mean customs value has already been adjusted. Calling it a ‘valuation adjustment request’ is legally imprecise. It is neither a requirement to amend the declaration nor a post-release decision. It is a procedural document. The company’s response enters the control file and may later be assessed when customs decides the matter and when that decision is challenged.
Identify the procedure first
The word ‘request’ can cover different procedures. Under Article 325(1) of the EAEU Customs Code, customs requests a document already identified in the goods declaration but not submitted with it. Failure to produce that document leads to refusal of release. Saying that the foreign supplier holds it does not remove the obligation.
Paragraph 4 concerns additional commercial, accounting and other documents, information and written explanations. Grounds may include an incomplete original package, insufficient support or indications of non-compliance with Union or member-state law, including potentially inaccurate information. A demand to ‘provide everything’ is not enough. The identified concern, requested material and fact under review must be connected.
The request’s legal basis determines the deadline, the consequences of non-production and the possibility of release before the review ends. There is no universal ten-day pre-release response period. Depending on the request, when the initial documents were supplied and whether the information affects payments, the response may be due at least four hours, two hours or one working day before the applicable release period expires. An error here can lead to refusal before the substantive price dispute begins.
Failure to answer a request under Article 325(4) before release does not invariably require refusal. Customs refuses release where the documents, information, written explanations or reasons for their absence are not submitted on time and the conditions for release under Article 121 of the EAEU Customs Code are also unmet.
Article 325(9) adds a further requirement: documents and information requested under paragraphs 1 and 4 must be submitted together as one package for each request. Sending a few available files does not give an unrestricted right to supplement the response after the deadline. Include reasons for missing additional documents and evidence of attempts to obtain them in the same package.

When release against security is available
Where additional information affects customs payments, customs also notifies the declarant of the possibility of Article 121 release and supplies a security calculation, except where security is not required. The calculation shows how much cash or bank-guarantee capacity may be tied up until the review ends. That amount may rival storage and vehicle waiting costs or make immediate release financially difficult.
Security may allow release before the review ends, but it neither confirms the declared value nor ends control. The mechanism is not always available. Where customs identifies possible prohibitions, restrictions or trade-defence measures covered by Article 121 and compliance is unconfirmed, security alone is insufficient.
After release under Article 121, the review continues. If the requested materials were supplied before release, customs must finish within thirty calendar days of their submission. Additional materials not supplied within the pre-release deadline may be submitted within sixty calendar days of ДТ registration, except in the case covered by Article 314(2) of the EAEU Customs Code. For materials supplied during that post-release period, the thirty days run from submission; if none are supplied, from expiry of the sixty-day period. A further request is due within ten calendar days of registration and suspends the review-completion period from registration until receipt of the response or expiry of the response deadline. This later-submission procedure does not replace a document required under Article 325(1).
What changes after customs release
A separate review begun after release follows Articles 326 and 340 of the EAEU Customs Code and, for a Russian company, Article 225 of Federal Law No. 289-ФЗ. It generally lasts no more than sixty calendar days unless EAEU or Russian law provides otherwise. A request suspends that period from registration until the documents arrive or the response period expires. A reasoned application may obtain an extension of the response deadline by no more than two months from its original expiry; applying alone changes nothing. The request must state the review’s start date, except for automated checks without an officer’s involvement. Do not combine this regime with the pre-release timetable.
Evidence of the transaction value
Next, examine the declared customs value itself. Customs checks more than the invoice total or its difference from database prices. The review covers the choice and application of the valuation method, the value’s structure and amount, the price actually paid or payable, additions, permitted deductions and the reliability, quantifiability and documentary support of the information.
As far as possible, customs valuation rests on the transaction value of imported goods: Method 1. A price difference from customs data does not automatically exclude it. Once customs identifies specific indications of inaccuracy, a contract and proof of payment alone may not resolve the concern. The response must address the particular fact in doubt.
EEC Board Decision No. 42 does not prescribe a universal document package for every shipment. Its list is illustrative; the request must account for the transaction, goods and fact being checked. The number of attachments proves nothing by itself. The issue is whether they substantiate the relevant component of the calculation and agree with the other records.
Linking a payment to the shipment
A bank statement records money moving but may not identify the shipment paid for. Depending on the arrangement, the link may be established through the contract, order or specification, invoice, bank messages and accounting records. There is no mandatory set. The records must show which obligation was performed and which shipment the payment covers.
One transfer may pay several invoices and declarations without conflicting with Method 1. Problems arise where the allocation exists only in an internal spreadsheet, its total differs from the bank record, the same payment is counted twice or the table changes after the review begins without explanation. The traceability of the whole payment then becomes doubtful.
‘Payment through an agent’ does not adequately describe every third-party arrangement. Where another company pays for the buyer, establish its basis for performing that obligation and the seller’s credit against the relevant invoice. Where the buyer pays someone else on the seller’s instructions, check the recipient’s authority and discharge of the debt to the seller. Where an intermediary only processes the transfer, identify its fee separately from the goods price.
An intermediary agreement’s title does not determine the customs treatment of its fee. Examine the actual functions, whose interests the intermediary serves, who bears the cost and whether the fee is already in the price. Commission or brokerage incurred or payable by the buyer is added where it is not included in the price actually paid or payable. The exception is a buying commission paid to the buyer’s agent for representing the buyer outside the EAEU in purchasing the imported goods. Calling someone the ‘buyer’s agent’ does not establish that exception if the actual arrangement shows otherwise.
Substantiating discounts and pricing
For a discount, customs examines the pricing history. Trace the original price, the reason and date of reduction, the goods and quantities covered and the revised amount in the transaction documents. A volume discount requires the discount scale and evidence that the quantity condition was met. A markdown depends on condition or completeness; a promotion on its rules and duration.
A retrospective bonus does not automatically reduce the customs value of goods already imported. Establish whether it changes the price of specific shipments or is separate remuneration for a period, and whether the attributable amount can be quantified. Without that link, it describes the parties’ commercial relationship rather than revising the price of the goods being valued.
A document created after the review begins is not inadmissible solely because of its date. But a later supplier letter must not be presented as an agreement already in place when the transaction was concluded. Its weight depends on the primary records behind it, why it was produced later and whether it confirms an existing fact or constructs a new account after customs’ request.
A price list may establish an initial offer level, discount structure or commercial level of sales. It does not automatically prove this shipment’s price. A list for another period, market or quantity may weaken the declaration unless the difference from the actual price is explained.
Checking whether prices are comparable
Test customs’ price data for comparability. Higher recorded values for identical or similar goods may justify checking the declaration but cannot replace a valuation. Compare model, characteristics, manufacturer, origin, quality, condition, quantity, commercial level, import period, delivery terms and price components. Totals are not directly comparable if one includes carriage, insurance or commission and the other does not.
A relationship between buyer and seller does not automatically exclude Method 1. Customs must first identify indications that it may have influenced the price. The declarant then explains the pricing mechanism, comparable sales to independent buyers, test values and other transaction facts. A general demand to prove that every intragroup price is ‘market-based’ is not enough without specific grounds; once those grounds are identified, general assurances are not enough either.
Transport disputes often require costs to be separated by route segment and the party bearing them identified. A forwarder’s combined invoice may cover collection from the seller, terminal handling, international carriage, insurance and delivery after arrival. A single total without supporting detail does not establish which amount should be added or deducted.
Supreme Court Thematic Review No. 9/2026 confirms that transport costs have no closed list of acceptable evidence. That does not make every collection of files sufficient. In one contractual arrangement, orders, invoices, bills of lading and contract terms establish the amount. In another, the supplier’s figures are insufficient without tariff sources, underlying data and the calculation method. The court assesses whether the documents establish the actual amount and its connection to the goods being valued.
A licence agreement alone does not determine the customs treatment of royalties. Two conditions must coincide: the payment relates to the imported goods and is directly or indirectly a condition of their sale for export to the EAEU. Examine the licensed rights, goods covered, calculation base, recipient, relationship between seller and rights holder and whether the goods could be purchased without the licence obligation.
Where one licence payment covers imported goods together with other goods, services or rights, only the attributable share may enter customs value. An arbitrary percentage is not sufficiently quantifiable. The allocation must follow verifiable data, rather than create a new uncertainty.
When foreign documents are unavailable
Customs may request the export declaration, manufacturer’s cost breakdown, foreign seller’s accounting records or other materials the Russian buyer does not hold. They may matter to the specific review, but they are not universal prerequisites for Method 1.
‘The supplier will not provide it’ is not a complete explanation. State whether the document exists, whether this transaction uses it, who controls it and what attempts were made to obtain it. Alternative evidence must address the same fact. If a cost breakdown is requested because the price is unusually low, transport records and proof of payment do not explain how that price was set.
Keep the two Article 325 situations separate. Under paragraph 4, objective reasons for a missing additional document, correspondence with its holder and other evidence may affect assessment of the response. Under paragraph 1, an explanation cannot replace a document already identified in the ДТ; failure to provide it leads to refusal of release.
Finding contradictions before submission
Contradictions often emerge only when records are compared. The order price differs from the final invoice. Payment predates the agreed discount. A freight invoice concerns another route. A revised specification appeared after the review began. Each document may seem persuasive alone, while the combined chronology still needs explaining.
Proving submission of the response
Submission evidence is a separate issue. A persuasive response has limited value if the company cannot prove which files customs’ system accepted and when. A draft letter proves preparation, not delivery. The enclosure list records the package; system receipts establish receipt and timing according to their status. Compare the customs representative’s report with those receipts and the attachments actually uploaded.
Customs may accept the information and release the goods. Where review continues after release, it either confirms completion and the availability of return or setoff of security, or decides to amend the ДТ. Before release, it may require amendments where documents, explanations, other control results or expert findings do not substantiate the information’s accuracy and completeness or resolve the grounds for review. Failure to meet the Code’s obligations may lead to refusal. A request is neither an adjustment nor a final decision. It is premature to agree to a valuation adjustment in the response or turn the explanation into an appeal against a decision not yet made. At this stage, the task is primarily to establish the facts.
The same file may later support an administrative or court appeal. The Supreme Court cautions against turning judicial proceedings into a fresh customs review or assembling a new file for the declarant. A material document first produced in court requires an explanation for its earlier absence. The court also checks customs’ conduct: whether specific doubts were disclosed, deficiencies in the first response explained and a real opportunity provided to supplement the evidence.
