One Kilogram Over at EAEU Customs — How a Weighing Error Becomes an Administrative Offense in Russia
One extra kilogram above the stated figure is an amount that a high-quality scale frequently shows within its own margin of error. In a warehouse, this is an insignificant detail. At customs, however, such a discrepancy can become the basis for an administrative offense report under Part 2 of Article 16.2 of the Code of Administrative Offenses of the Russian Federation (CAO RF), leading to a fine ranging from one-half to double the amount of the unpaid duties — and occasionally to the confiscation of goods.
The logic behind turning a physical variance into a legal fact is not immediately obvious, but it becomes clear once you examine the mechanism from the inside. Understanding it matters, if only because in March 2024 the Constitutional Court drew a line that customs authorities had regularly been crossing.
How the System Operated Before 2024
Article 84 of the Customs Code of the Eurasian Economic Union (hereinafter — EAEU Customs Code) obligates the declarant to provide accurate information. The legislator does not allow for a concept of «almost accurate»: information is either precise or it is not. This binary logic creates grounds for administrative prosecution over discrepancies that, by all physical standards, fall within the acceptable margin of error.
When dealing with goods subject to specific duty rates (calculated in euros per kilogram or liter), the net weight directly enters the calculation of payments. At a rate of 0.5 euros per kilogram, one undeclared kilogram means an underpayment of 0.5 euros. The administrative offense under Part 2 of Article 16.2 of the CAO RF is established by the mere fact of any underpayment, regardless of how small. Russian administrative law does not recognize the concept of «triviality» (maloznachitelnost) with respect to customs payments at the stage of qualifying the offense.
For goods subject to ad valorem rates (where the duty is a percentage of the value), weight is equally in play. Customs authorities calculate the customs value index: the ratio of the declared price to the net weight. If the weight increases while the value remains unchanged, the index falls — and this triggers a flag for possible understatement of the contract price. A single kilogram of weight used to serve as a marker of price credibility.
This approach produced cases that today look absurd. LLC «Gazpromneft — Lubricants» was fined 164.97 rubles because a supplier used non-standard pallets that turned out to be heavier than usual. The weight of one product in the shipment increased; another decreased by the same amount. The total customs duties did not change by a single ruble. Nevertheless, courts of three instances found the company guilty: formally inaccurate information for one of the products had been declared, and that was deemed sufficient.
The second applicant, LLC «VIREM RUS,» faced the same logic under similar circumstances. These two cases became the basis for a complaint to the Constitutional Court.
What Changed with Ruling No. 9-P of the Constitutional Court of the Russian Federation, March 5, 2024
On March 5, 2024, the Constitutional Court issued a ruling that changed the rules of weight disputes.
The Court held that Part 2 of Article 16.2 of the CAO RF constitutes a substantive offense: liability arises only when inaccurate information actually led — or could have led — to a real reduction in customs payments. If a weight discrepancy for one product is offset by an adjustment for another product within the same customs declaration, and the total duties for the entire shipment did not decrease, no administrative offense has occurred. Prosecution under such conditions was found unconstitutional.
Previously, customs authorities assessed each product in a declaration separately. Under the new approach, the assessment covers the entire shipment as a whole.
| Parameter | Before Ruling No. 9-P | After Ruling No. 9-P |
|---|---|---|
| Unit of Assessment | Individual item in the customs declaration | The entire shipment under the declaration |
| Grounds for a Fine | Any discrepancy in the stated data | A discrepancy that caused a real reduction of payments |
| Fine with Zero Underpayment | Imposed (e.g., the Gazpromneft case) | Impermissible — no offense exists |
| Legal Basis for Defense | None | Constitutional Court Ruling No. 9-P |
Weight discrepancies themselves have not gone away. If a discrepancy results in an actual underpayment, an administrative case remains a real prospect and the sanctions apply in full.
Where the «Extra» Kilogram Comes From
Most of the time, a discrepancy stems from one of four situations — and none of them involve fraudulent intent.
Confusion between net and gross weight. The EAEU Customs Code introduces the concept of «net weight for customs purposes»: primary packaging that cannot be separated from goods before consumption (a blister pack of tablets, a tin can, a perfume bottle) is included in the net weight. Following everyday logic, a declarant often subtracts the packaging weight and ends up with a discrepancy. In a shipment of 10,000 bottles, a difference of 10 grams of plastic per unit produces a 100-kilogram discrepancy.
Physical properties of the goods. Hygroscopic cargo (grain, cotton, certain chemicals) absorbs moisture in transit. Goods shipped from a dry climate arrive at a humid port weighing more than when they left. Without an expert report and documented standards for natural weight change, proving that the «extra» kilogram is simply water from the air is virtually impossible.
The selective weighing method. Customs rarely weighs an entire shipment. An inspector takes 10 boxes out of a thousand, calculates the average weight, and multiplies by the total count. If the sample included a box with denser cardboard or extra tape, the extrapolation produces a fictitious overweight across the entire shipment. In reality, there may be no discrepancy at all.
Cross-checking with foreign customs declarations. Customs authorities may request the exporter’s declaration through interagency exchange mechanisms. If a Chinese exporter declared 20,500 kg and a Russian importer declared 20,499 kg, the 1-kg difference is treated as a misstatement. Arguments that the exporter made an error or rounded the figure run into the presumption of accuracy attached to official foreign documents. This is the exact mechanism applied by Baltic Customs in case No. A56-63017/2021: export declarations obtained from the General Administration of Customs of the People’s Republic of China showed different price data, and customs used them to adjust the customs value — a move upheld by courts of three instances.
What to Do
Calculate the total payment amount immediately upon receiving an administrative offense notice. The first question for any defense: did the weight discrepancy actually cause an underpayment of duties across the entire shipment? If not, prepare a written legal position citing Constitutional Court Ruling No. 9-P of March 5, 2024, and file a motion to dismiss. The calculation must be in writing, using the figures from the declaration.
Request the weighing methodology documentation. The customs inspection report must state whether full or selective weighing was used, the type of scales, and how many packages were weighed. If selective weighing was used, assess whether the sample was representative. Request the technical passport and calibration certificate for the scales: the calibration must be valid on the exact date of the inspection.
Assemble the documentary weight chain. The weight recorded by the carrier in the bill of lading or CMR consignment note is an independent source that courts treat with high confidence. Add weight certificates from marine surveyors at loading and packaging specifications from the tare manufacturer. If the declaration was based on data from a foreign counterparty, immediately request an official letter from them explaining the discrepancy: courts do not accept verbal explanations of a foreign partner’s errors without written confirmation.
Commission an expert report for hygroscopic goods. An independent opinion on the physical properties of the cargo and its transit conditions is the only way to substantiate a weight change during transport. The Chamber of Commerce and Industry issues such reports; courts accept them as evidence. Without an expert opinion, the argument that «the goods absorbed moisture» will be dismissed as unsubstantiated.
Build weight controls into your contracts. Add a tolerance clause to supplier contracts (±0.5% or a specific kilogram figure). Require photographs of the scales at the time of dispatch. Include an obligation to list the tare weight as a separate line item in the packing list.
If a discrepancy is identified before the customs declaration is filed, there is a straightforward path: Article 84 of the EAEU Customs Code grants the declarant the right to inspect and measure goods before declaring them. Weigh the goods independently at the temporary storage warehouse, record the result, and declare the actual weight. No offense arises.
Ruling No. 9-P has put an end to the most inequitable practice: customs authorities may no longer fine importers for technical discrepancies that did not reduce budget revenues. Where an underpayment does exist, the system operates with its usual severity. The difference between an administrative case and a clean clearance today often comes down to a single line in a calculation — exactly how many rubles of duties failed to reach the budget because of a disputed kilogram.
