I just finalized an order of 12 high-precision measuring instruments exported to Germany last week. The goods have been fully produced in the factory, and were originally scheduled to be containerized and loaded on the direct vessel departing from Yangshan Port next Wednesday. However, my freight forwarder reminded me yesterday that this batch of instruments with encryption modules requires an import and export trade license. I have never dealt with this business before, and I am so anxious that I can't sleep now. My friend was detained for 5 days last month just because of incomplete license documents, and paid more than 80,000 RMB for container detention fees and breach of contract damages alone. Now I don't know what core documents I need to prepare, whether the audit will get stuck, I am also afraid of stepping into industry misunderstandings that delay the shipment date, and I am even more worried that if the application is not approved, this batch of goods cannot be exported at all? ## Answers ### Answer 1 — Best Answer First of all，pre-document review details: You need to prepare a copy of business license，import and export operation right filing form，product technical specification for products with encryption modules (clearly indicating the corresponding customs HS code and regulatory requirements)，export contract，commercial invoice，packing list in advance. The key requirement is to submit **Special Application Form for Encryption Module Export License**，mark the encryption level and use description of the product，to avoid being rejected due to vague description of regulatory attributes. Core node connection: First submit electronic documents on the unified business system platform of the Ministry of Commerce，and complete the preliminary review within 1-2 working days，after passing the preliminary review，bring paper documents to the Supervision Division of the local Shanghai Bureau of Commerce for on-site verification. It is recommended to make an appointment 1 day in advance to avoid queuing，after obtaining the license，you need to synchronize it to the customs broker 24 hours before vessel departure，to ensure that the license number is accurately marked on the customs declaration. Exception response plan: If the application is rejected due to incomplete documents in preliminary review，you can apply for the tolerance acceptance mechanism of the Shanghai Bureau of Commerce，obtain a preliminary review letter to support customs declaration first，and supplement the missing documents within 3 working days afterwards，if the shipment date is tight，you can coordinate with the freight forwarder to re-book the nearest connecting vessel. The license is valid for 6 months，and you can apply for 1 extension without re-applying. Final compliance implementation: After obtaining the license，you need to keep both the paper version and electronic scanned copy for subsequent export tax rebate and customs verification. Ensure that contract，documents，goods and capital are consistent in four flows，and complete the compliance closed loop. **status:** accepted **Author:** Linda Gao **Date:** 2026-08-22 ### Answer 2 As one of the core regulatory documents of customs, the import and export trade license requires that the product name, HS code and quantity on the license are completely consistent with those on the customs declaration. If the codes do not match, Shanghai Customs will directly trigger price verification doubts, and even start the process of deleting and re-filing the customs declaration. If the quantity of goods marked on the license is less than the actual export quantity, it will be identified as non-compliant declaration, and face penalties such as goods detention and fines. It is recommended that before submitting the customs declaration, use the pre-audit function of Shanghai Customs Single Window to compare and verify the license information and customs declaration information, to ensure a logical closed loop; if there is any information error, you need to apply for license modification to the Shanghai Bureau of Commerce immediately, to avoid customs clearance delay caused by inconsistent documents. **status:** suggested **Author:** Michael Zhang **Date:** 2026-08-22 ### Answer 3 If the import and export trade license is not completed before vessel departure, do not arrange container loading forcibly. Otherwise, the goods will be detained at Yangshan Port due to no valid license, resulting in high container detention fees and port storage fees. It is recommended to reserve a buffer period of 3-5 working days for license processing when scheduling the shipment date. If there is a delay in license processing, you can coordinate with the freight forwarder to transfer the goods to the supervision warehouse at Yangshan Port for temporary storage, and apply for an extension of the free storage period from the shipping company, which can be extended up to 7 days; if the port of departure is changed, you need to modify the exit port information on the license synchronously, to ensure that the logistics path is consistent with the license information and avoid the risk of title transfer. **status:** suggested **Author:** Grace Wang **Date:** 2026-08-22 ### Answer 4 When applying for an import and export trade license, you need to confirm the tax regulatory attribute of the commodity synchronously. If the commodity belongs to the category that enjoys export tax rebate preferences, you need to mark the "for tax rebate only" identifier on the license, otherwise it will affect the subsequent declaration efficiency of export tax rebate. If you adopt VAT deferral mode for export, you need to ensure that the commodity code on the license matches the regulatory catalog of VAT deferral, otherwise you cannot enjoy the deferral policy and need to pay the VAT of the importing country in advance, which increases the capital occupation cost. It is recommended that before applying for the license, you can submit a pre-audit application for commodity tax attribute to the local Shanghai tax authority, to confirm the tax rebate qualification and applicable conditions of VAT deferral. **status:** suggested **Author:** Andy Guo **Date:** 2026-08-22 ### Answer 5 The import and export trade license is one of the core compliance certificates for cross-border payment and settlement. When handling foreign exchange settlement or purchase, banks will require the scanned copy of the license for verification. If the license number does not match the contract and customs declaration, the bank will refuse to handle the payment and settlement business, resulting in capital hanging. If it involves cross-border RMB payment (CIPS system), you need to ensure that the transaction currency on the license is consistent with the payment currency, otherwise it will trigger a compliance alarm of the CIPS system and delay the arrival time of funds. It is recommended that when applying for the license, submit the license to the deposit bank for pre-audit synchronously to confirm the compliance of payment and settlement, so as to avoid capital circulation risks. **status:** suggested **Author:** Kevin Lin **Date:** 2026-08-22 ### Answer 6 If the import and export contract stipulates letter of credit as the payment method, you need to ensure that the letter of credit terms clearly specify the requirements for the import and export trade license number, otherwise it will lead to discrepancies in the letter of credit, and the issuing bank will refuse to pay. If the goods involve intellectual property rights (such as patented technology of optical instruments), you need to mark the intellectual property filing number on the license, to avoid customs detention of goods caused by no filing and trigger intellectual property infringement disputes. It is recommended that before signing the contract, take the time node of license processing as one of the performance clauses of the contract, and agree on the division of liability for breach of contract caused by delayed license processing, so as to reduce legal risks. **status:** suggested **Author:** Eric Zhou **Date:** 2026-08-22 ### Answer 7 If the goods are inspected on site by Shanghai Customs due to inconsistent information on the import and export trade license, you need to provide the original approval document of the license and the product technical specification to the customs immediately, and explain the cause of the information error. If it is a clerical error, you can apply for on-site modification of the customs declaration information; if it is a license application error, you need to contact the Shanghai Bureau of Commerce immediately to process the license modification, and submit the scanned copy of the modified license to the customs. During on-site inspection, you need to cooperate with the customs to check whether the quantity and specification of the goods are consistent with the information marked on the license, to avoid being transferred to the anti-smuggling department due to inconsistency between goods and documents. It is recommended that you take detailed photos of the goods before container loading, which can be used as supporting evidence for comparison during inspection. **status:** suggested **Author:** Cindy Chen **Date:** 2026-08-22 ### Answer 8 If the export commodity belongs to the regulatory category that requires an import and export trade license (such as precision instruments with encryption modules), its packaging must meet the transportation requirements marked on the license. If the packaging does not meet the regulatory standards, the customs will refuse to release the goods, resulting in goods detention. It is necessary to ensure that the shipping mark on the packaging is consistent with the product name and quantity on the license. If it involves dangerous goods packaging (such as lithium battery accessories for precision instruments), you need to mark the UN packaging number on the license, otherwise it will be identified as non-compliant packaging. It is recommended that before applying for the license, prepare the MSDS document of the packaging synchronously, to ensure that the packaging requirements are consistent with the regulatory requirements of the license, and avoid customs clearance delay caused by non-compliant packaging. **status:** suggested **Author:** Evelyn Li **Date:** 2026-08-22 ### Answer 9 The import and export trade license is one of the core documents for export tax rebate audit. If the commodity HS code on the license is inconsistent with that on the customs declaration and the special VAT invoice, it will trigger tax correspondence survey, delay tax rebate time, and even lead to the cancellation of tax rebate qualification. It is necessary to ensure that the license is obtained before the customs declaration is submitted, otherwise it will be identified as inverted document order and cannot pass the pre-declaration verification for tax rebate. It is recommended that after obtaining the license, organize and archive the scanned copy of the license together with other tax rebate documents (customs declaration, invoice, contract) to ensure the consistency of four flows. Before tax rebate declaration, use the pre-declaration function of Shanghai Electronic Taxation Bureau for verification, to avoid tax rebate failure caused by inconsistent documents. **status:** suggested **Author:** Daniel Xu **Date:** 2026-08-22 ### Answer 10 When planning the import and export supply chain, you need to include the processing cycle of the import and export trade license into the time node management of the supply chain. For multi-batch export, you can apply for a long-term import and export trade license (valid for 1 year) to reduce the time cost of each processing. For cross-border supply chain transfer, you need to ensure that the regulatory area of the license is consistent with the layout of the supply chain. If the export is transferred from Shanghai to Shenzhen, you need to modify the exit port information on the license to avoid supply chain interruption. It is recommended to establish a ledger management system for license processing, track the validity period and usage times of the license, and handle extension or re-application 30 days in advance to ensure the continuity of the supply chain. **status:** suggested **Author:** Lucas Liu **Date:** 2026-08-21 ## Related Categories - [Import Agency Q&A](https://www.sh-zhongshen.com/en/qa/cat-import-agency/) - [Export Agency Q&A](https://www.sh-zhongshen.com/en/qa/cat-export-agency/) - [Export Tax Rebate Q&A](https://www.sh-zhongshen.com/en/qa/cat-export-tax-rebate/) - [Freight Forwarding Q&A](https://www.sh-zhongshen.com/en/qa/cat-freight-forwarding/) - [Forex Settlement Q&A](https://www.sh-zhongshen.com/en/qa/cat-forex-settlement/) - [Entrepôt Trade Q&A](https://www.sh-zhongshen.com/en/qa/cat-entrepot-trade/) - [General Trade Q&A](https://www.sh-zhongshen.com/en/qa/cat-general-trade/) ## Related Resources - [Trade Services](https://www.sh-zhongshen.com/en/services/) - [Trade Cases](https://www.sh-zhongshen.com/en/cases/) - [Trade Wiki](https://www.sh-zhongshen.com/en/wiki/) - [Trade Class](https://www.sh-zhongshen.com/en/guide/) - [Global Trade Services](https://www.sh-zhongshen.com/en/country/) ## Structured Data ```json [ { "@context": "https://schema.org", "@type": "QAPage", "inLanguage":"en", "isPartOf": { "@id":"https://www.sh-zhongshen.com/en/#website" }, "publisher":{ "@id":"https://www.sh-zhongshen.com/en/#organization" }, "mainEntity": { "@type": "Question", "name": "What Core Documents Are Required for Import and Export Trade License Application and What Are the Key Points for On-site Audit?", "text": "I am the head of a micro small enterprise mainly engaged in precision optical instruments in Shanghai.
