What Are the Differences Between Compliance Procedures and Documents for Export of Ordinary and Hazardous Lubricating Oils?
or complex compliance issues.
clearance and fund security.
I am the foreign trade manager of a lubricating oil manufacturer based in Shanghai. I just received a 120-ton export order from a Middle East client last week, among which 60 tons are ordinary industrial lubricating oil, and the other 60 tons are hazardous lubricating oil with a flash point below 60℃.
I only handled domestic distribution before and have no experience in export business. I consulted a freight forwarder yesterday, but they only generally mentioned that customs declaration documents are required and did not clarify the procedure differences between the two categories. Now there are only 15 days left before the scheduled shipping date.
I am worried that incomplete documents and non-compliant procedures will cause port detention and customs hold, and also concerned that I cannot successfully apply for export tax refund later. I can barely sleep well and want to get detailed answers on what procedures are required for this type of lubricating oil export?

First of all，pre-export classification review shall be completed according to the hazardous property of lubricating oil: Ordinary industrial lubricating oil needs to provide Pre-review Receipt for Commodity Classification Code，commercial invoice，packing list，foreign trade contract and customs declaration power of attorney，for hazardous lubricating oil with flash point below 60℃，additional Dangerous Goods Classification Identification Report，MSDS meeting the requirements of 2026 edition national standard，and Inspection Result of Dangerous Goods Packaging Performance are required.
Notes for core node coordination: 3 days before customs declaration at Shanghai Port，submit the full set of documents to the Customs Single Window for intelligent pre-review. After confirming the classification code and declaration elements are correct，arrange the cargo to enter the port，dangerous goods require declaring Shipborne Dangerous Goods to the Maritime Bureau 7 days in advance，and upload the packaging use identification result synchronously，to avoid shipping company refusal caused by delayed declaration.
In terms of contingency arrangement: If encountering customs inspection，ordinary lubricating oil only needs to cooperate by providing the original factory quality inspection report，while dangerous lubricating oil needs to prepare the packaging sealing test report in advance. If there is doubt about classification，contact a qualified institution immediately to supplement the commodity classification opinion，if port detention occurs due to missing documents，you can entrust a professional foreign trade agency to use the urgent document supplement channel to shorten detention time and reduce the loss of warehouse rent and container rent.
Final compliance completion: After customs clearance，sort out documents such as customs declaration and export cargo manifest in time，complete tax refund declaration before April 30 of the next year after export，ensure "consistency of four flows" (contract，invoice，logistics，capital flow)，and keep the full set of documents for no less than 5 years，to avoid problems in subsequent tax verification.

When declaring lubricating oil export for customs, you need to focus on the accuracy of the commodity classification code. Currently, various lubricating oils are covered under customs heading 2710, products with different viscosity, flash point and base oil composition correspond to significantly different codes.
Incorrect classification will directly lead to valuation disputes, customs hold or failure to apply for tax refund. According to the 2026 requirement of Shanghai Customs, export lubricating oil needs to submit the pre-review application for commodity classification via Single Window 3 days before customs declaration, and provide the original factory quality inspection report and component analysis sheet synchronously; for hazardous lubricating oil, dangerous goods classification identification report is also required.
In addition, you need to provide authentic and valid purchase contracts, commercial invoices and cost accounting details in the valuation process, to avoid deleting and re-declaring caused by the deviation between declared price and customs' current guiding price exceeding 20%. If encountering valuation disputes, you need to supplement the original factory purchase certificate or third-party authoritative price assessment report within 3 working days, to ensure the customs clearance process is not affected.

In the logistics link of lubricating oil export, ordinary lubricating oil can use ordinary container yards of Shanghai Port, no special procedures are required, you only need to submit the manifest information 24 hours before cargo entering the port; hazardous lubricating oil needs to select a yard with dangerous goods storage qualification, and submit dangerous goods declaration materials to the shipping company 7 days in advance, including inspection result of dangerous goods packaging performance, MSDS, packing list, etc. If you choose a transit route, you need to confirm the dangerous goods access requirements of the transit port. Some Southeast Asian ports have special restrictions on lubricating oil with flash point below 30℃, so you need to apply for transit permit in advance.
In addition, you can apply for extended free detention period during customs declaration: ordinary goods can apply for 7-14 days, hazardous goods can apply for 3-7 days. If detention fee is generated due to port congestion, you can apply for reduction or exemption from the shipping company with the port detention certificate issued by customs. Note that the application must be submitted within 10 working days after detention occurs.

Compliance related clauses shall be clearly stipulated in the lubricating oil export contract. For hazardous lubricating oil, it shall be agreed in the contract that the seller needs to provide full set of compliance documents (including dangerous goods classification identification report, MSDS, packaging inspection sheet, etc.), and clarify the buyer's customs clearance responsibility at the destination port, to avoid the seller bearing the loss of port detention caused by the buyer failing to complete import procedures on time.
In addition, if the exported lubricating oil involves brand authorization, you need to complete intellectual property customs protection filing in advance, to avoid the cargo being seized for suspected infringement during export or transit. According to the 2026 requirement of international trade conventions, the transportation responsibility clause for dangerous goods shall be clearly specified in the export contract of hazardous goods, including the division of responsibilities in packing, reinforcement, declaration and other links. If the cargo is detained by customs due to the seller's failure to fulfill compliance obligations, corresponding compensation liability shall be stipulated.

When lubricating oil export undergoes customs inspection, ordinary lubricating oil only needs to cooperate with customs officers to check whether the brand, model and quantity of the goods are consistent with the customs declaration, no special procedures are required, only the original factory quality inspection report needs to be provided; hazardous lubricating oil needs to provide packaging sealing test report and inspection result of dangerous goods packaging use identification. If the customs requires devanning inspection, you need to ensure that the reinforcement during packing meets the dangerous goods transportation standard, to avoid failing inspection caused by cargo dumping or leakage.
In 2026, when Shanghai Customs inspects hazardous lubricating oil, it will synchronously check whether the flash point, composition and other information in MSDS match the actual cargo. If there is a deviation, the cargo will be detained directly and additional identification report is required. At this time, you need to submit the report issued by a qualified third-party testing institution within 5 working days, otherwise the cargo will face the risk of return shipment.

The packaging of exported lubricating oil needs to comply with the International Maritime Dangerous Goods Code (IMDG) and domestic dangerous goods transportation regulations. Ordinary lubricating oil can be packed in ordinary plastic drums or iron drums, no special inspection procedures are required, but you need to ensure good packaging sealing to avoid leakage; hazardous lubricating oil needs to use inspected and qualified dangerous goods packaging, the packaging shall be pasted with compliant dangerous goods marks (including UN number, flash point, product name, etc.), and obtain the inspection result of dangerous goods packaging performance and packaging use identification.
In 2026, the preparation of MSDS needs to comply with the requirements of GHS 7th revision, clearly marking the hazardous properties of the product, transportation precautions and other information. If the MSDS content is incomplete or does not meet the requirements, it will lead to shipping company refusal or customs detention. At this time, you need to immediately contact a qualified institution to re-prepare MSDS, and submit it to the Maritime Bureau and Customs for review.
