Recently, the Information Office of the People's Government of Guangxi Zhuang Autonomous Region held a press conference on tax-related crimes. At the meeting, the prominent problem of "oil evasion and tax evasion" on tankers was mentioned. Up to now, the whole region has inspected a total of 2328 gas stations and seized 482 cheating mainboards. It is also introduced that the next step will be to explore an intelligent supervision mode and pilot the use of "ID card two-dimensional codes" in the field of gas dispensers, so that gas dispensers can realize the full-cycle collection of information such as product manufacturing, verification, repair, supervision, complaint reporting, etc.

In fact, as early as 1985, tankers were included in the compulsory verification of measuring instruments; and in accordance with the provisions of the "the People's Republic of China Metrology Law", compulsory verification must be carried out by a legal metrological verification agency, and the verification period should not exceed half a year, and the tanker should be affixed. "Forced inspection mark".

With the further strengthening of supervision, in order to prevent the occurrence of cheating such as replacing the main board, the legal metering agency will install disposable lead seals with different codes at important positions such as the main board, encoder and adjustment device of the flow measurement converter of the fuel dispenser to prevent random replacement and adjustment.

the problem has arisen. Since tankers have tests, marks, lead seals and anti-cheating, how can illegal gas stations harm consumers?

1.Interception and tampering of refueling data

ways of cheating:setting parameters in the background of the tanker, screening and intercepting the refueling data, or tampering with the mainboard chip of the tanker, installing cheating software, and changing the metering accuracy of the tanker.

cases:On April 1, 2025, when the Xinxiang City Market Supervision and Administration Bureau jointly conducted an on-site inspection of a gas station, it was found that its No. 92 gasoline refueling gun was abnormal. The version model "PP140725" displayed on the tanker screen is suspected of cheating, and there is a data line leading to the manager's office on the tanker communication controller in the business hall. The law enforcement officers immediately seized and submitted the two main boards of the tanker for inspection, and the authority identified the tampering. The gas station involved was found to be an illegal income of 351025.4 yuan and was fined 1400 yuan.

2. Refitting fuel dispenser hardware

ways of cheating:to change the metering performance of the tanker by replacing the key hardware components of the tanker, such as the metering chip or the motherboard, so that the displayed refueling amount exceeds the actual refueling amount.

cases:In October 2024, the Qingyang Municipal Market Supervision Bureau conducted a daily inspection of the Zhengzhou gas station and found that there was a circuit board containing a microprocessor between the fuel dispenser's meter and control main board and the indicating device. After investigation, from April 23 to October 21, 2024, the party used 5 fuel dispensers that were modified without approval and destroyed the accuracy of measuring instruments, and the illegal income was 786800 yuan. In January 2025, the Qingyang Municipal Market Supervision Bureau imposed an administrative penalty of confiscating 5 fuel dispensers and 10 illegally installed circuit boards, with a total fine of 788700 yuan.

3. Installation of additional pulse generator

ways of cheating:to install an additional pulse generator on the tanker, which works at the same time as the original pulse generator, and increase the count of the tanker through the additional pulse signal.

cases:January 2024, when the Market Supervision Bureau of Yuzhou City, Henan Province inspected a gas station in its jurisdiction, it found that two tax-controlled fuel dispensers and communication controllers in use at the station were suspected of metering cheating. After investigation, the station's unauthorized modification of the disassembly and assembly of the fuel dispenser and the use of the fuel dispenser without approval violated the relevant provisions of the "Gas Station Measurement Supervision and Management Measures. In the end, he was sentenced to confiscation of the mainboard and communication controller of the tanker and an administrative penalty of 348000 yuan.

gas stations"

in today's rapid technological update, the original tax control device can not meet the requirements of modern tax management. In addition, there are many "acquired problems" in the case of congenital defects in the tax control device of the tanker ".

, some gas station enterprises have imperfect financial systems, low tax awareness, weak tax legal awareness, untrue financial accounting, irregular use of invoices, and even use personal accounts to collect business funds, falsely report sales income, and modify tax declaration data at will. There is a phenomenon of non-declaration and less declaration. The installation and use of refueling equipment and tax control devices lack unified coordination and control by departments. The reliability of self-declared data of gas stations is poor, and it is difficult to obtain real sales data. The problem of selling oil out of the machine exists, and on-site inspection and other supervision methods are difficult to work. The metering supervision and tax management of gas stations have become a difficult problem in the fine management.

The Exploratory Advance of Supervision Mode of Domestic Refined Oil Industry

, in order to strengthen the supervision of the refined oil industry and crack down on the existing illegal and illegal business practices of lack of weight and tax evasion, the intelligent lead seal of the tanker came into being. The intelligent lead seal adopts real-time monitoring, wireless networking, active early warning and other technologies, and has the full business process functions of lead seal inspection task arrangement, distribution, execution, recording, traceability and so on, reflecting a high degree of accuracy and strict protection. It can monitor the key parts of the tanker in real time. Once it detects that someone is trying to illegally disassemble or tamper with the internal structure and parameters of the tanker, it will immediately issue an alarm and transmit relevant information to the supervision system.

from the perspective of regulatory practice, this system is reshaping the operating logic of the refined oil market. On the supervision side, the real-time alarm mechanism allows the lead seal breaking behavior to be captured in real time, and with the traceability function of the supervision platform, the passive situation of "after-the-fact investigation" has been completely changed. For gas stations, the closed-loop management formed by intelligent lead seals not only eliminates the internal cheating space, but also reduces the compliance cost through digital records.fee payers can effectively avoid consumption disputes of "lack of weight and lack of weight" through transparent measurement supervision; more far-reaching is that the operational data deposited by the system provides an accurate basis for tax collection and management and market analysis, and promotes the industry from "passive supervision" to "active".compliance "transformation.
