Do newly purchased gas cylinders need to undergo special inspection before they can be used?

Special equipment must be inspected before it is put into use; even for new equipment, it is not necessary to send it for inspection unless it has already been inspected by a specialized inspection agency at the time of purchase and a corresponding inspection report is available.

I understand that it’s not necessary: according to the \"Regulations on the Safety Supervision of Gas Cylinders\" (revised in 2015), inspections are the responsibility of the manufacturer, while users are not required to carry out such inspections, but registration is necessary. Article 12: Before cylinders and their accessories are put into formal operation, type tests shall be conducted in accordance with the requirements of safety technical specifications and relevant standards. When the design documents or the main manufacturing process are changed, or when production resumes after a shutdown of more than 6 months, a type test of the gas cylinders shall be conducted. Article 13: When developing new types of gas cylinders and their accessories, type testing and technical evaluation shall be conducted. Article 14 Gas cylinders shall undergo supervised inspection on a case-by-case basis before they can be released from the factory (cylinders released from the factory shall comply with the contract or other relevant regulations). At the time of shipment, the manufacturer shall indicate on a prominent position on the cylinder the manufacturer’s manufacturing license number and corporate code, as well as the cylinder’s serial number, using a stamp (or some other permanent method). The manufacturer shall also provide each customer with a certificate of conformity in the form of a plaque or some other means that can be attached to the cylinder, and issue a batch inspection quality certificate for each batch of cylinders. The contents of the product qualification certificate and the batch inspection quality certificate shall comply with the provisions of the relevant safety technical specifications and product standards. The above requirements stipulate that gas cylinders must undergo safety inspections before leaving the factory ； Before putting it into use, the following is also required: Chapter 4 Cylinder Filling, Article 23 – Cylinder filling units shall submit a written application for a filling license to the special equipment safety supervision agency of the provincial quality supervision department. Upon review, those found to meet the requirements will be issued a \"Cylinder Filling License\" by the provincial quality supervision department. Those who do not hold a Gas Cylinders Filling License shall not engage in gas cylinder filling work. Article 24: The validity period of the Gas Cylinder Filling License is 4 years. Before the expiration of this period, the gas cylinder filling unit shall apply to the original approving authority for a renewal of the Gas Cylinder Filling License. Those who fail to submit an application as required or are not approved for a renewal of their Cylinder Filling License shall not continue to engage in cylinder filling work after the expiration of its validity period. Article 25 Gas cylinder filling units shall meet the following conditions: (1) Possess a business license ； (II) There are technical personnel and special equipment operators capable of meeting the requirements for gas cylinder filling and safety management; there are complete filling facilities, tools, testing methods, as well as suitable premises for filling, all appropriate to the type of gas being filled, along with safety facilities that meet the required standards ； (III) Possess a certain gas storage capacity and a sufficient number of gas cylinders owned outright ； (IV) Comply with the relevant safety technical specifications for cylinder filling stations and **standard requirements, and establish a sound quality assurance system and safety management system for cylinder filling.

I don’t quite agree with your view; even products that pass factory inspections can have defects, and testing new safety valves before use is also done to prevent accidents. Thank you again for your advice. I think it’s better to get it checked, just in case… There’s a lack of legal support; if that doesn’t work, ask for a special inspection~~
