What core compliance points should be focused on? ## Question I am the procurement supervisor of a machinery manufacturing enterprise in Shanghai. Last month, I finalized an order for a batch of high-strength industrial bolts with a German supplier, which is the first time we import such precision fasteners. I heard from peers before that imported fasteners are easily seized by customs due to incomplete documents and incorrect classification, and we have to pay port detention fees and document modification fees, which is a headache just thinking about it. Now I am eager to find a Shanghai agency to help with the operation, but I am afraid that the process is too cumbersome, and unprofessional agents will cause more trouble instead, resulting in the goods not arriving at the factory in time and delaying the start of the production line. I would like to ask if it is really troublesome to find a Shanghai agent to import bolts? Are there any special points to pay attention to to avoid these pitfalls? ## Answers ### Answer 1 — Best Answer First，the details of pre-document review. It is necessary to focus on checking whether the **certificate of origin** fully matches the brand，model and material of the bolts，to ensure accurate HS code classification. Incorrect classification will directly trigger customs valuation disputes or customs seizure. At the same time，the quality inspection report of bolts should be prepared in advance，especially for high-strength industrial bolts，which need to comply with GB/T 1228 standard，to avoid being required to submit for inspection due to non-compliance with standards. In terms of core node connection，the agent needs to complete the pre-review of documents 3 working days before the goods arrive at the port，and simultaneously connect with the customs broker to enter the manifest，to ensure that the declaration is completed within 12 hours after the goods arrive at the port. In case of customs control inspection，it is necessary to coordinate with on-site inspection experts at the first time，provide the material certificate and purpose description of the bolts，and shorten the inspection duration. The exception contingency plan should cover three core scenarios: inconsistent documents，valuation disputes，and unqualified inspection: when documents are inconsistent，the **document modification green channel** can be activated，and correction can be completed within 24 hours，in case of valuation disputes，supporting materials such as procurement contracts and foreign exchange payment vouchers shall be provided，if the inspection is unqualified，the return or rectification plan shall be activated to avoid long-term port detention. After the final compliance implementation，the agent needs to provide a full set of documents such as customs declaration form and tax receipt simultaneously，to ensure full compliance of the enterprise's subsequent financial entry and tax deduction. **status:** accepted **Author:** Lucas Liu **Date:** 2026-08-12 ### Answer 2 The core of customs declaration for imported bolts is the accurate classification of HS code. A common misunderstanding is to classify high-strength bolts as ordinary fasteners, but in fact, the code needs to be subdivided according to tensile strength and material. Incorrect classification will not only lead to incorrect application of tax rates, but also trigger customs valuation review, and even initiate retrospective adjustment, resulting in additional late fees. In addition, the customs will focus on verifying the authenticity of the procurement contract when valuing imported bolts, and it is necessary to ensure that the deviation between the contract price and the market fair price does not exceed 10%. If the deviation is too large, supporting materials such as supplier quotations and transaction records of the same batch of products need to be provided. For enterprises importing for the first time, it is recommended to submit documents to the agent for pre-classification review 3 working days in advance, to avoid port detention fees and document modification fees caused by document modification after arrival at the port. **status:** suggested **Author:** Eric Zhou **Date:** 2026-08-12 ### Answer 3 For the logistics link of imported bolts, focus should be placed on cargo right control and transportation timeliness. If LCL transportation is selected, it is necessary to ensure that the packaging of bolts meets the moisture-proof requirements, to avoid rusting of bolts due to high humidity in the container. At the same time, it is necessary to confirm the free storage period of Shanghai port in advance, which is generally 7 days. If the free storage period is exceeded, a container detention fee of about 100 yuan per container will be incurred every day. In case of space shortage or container rollover, the agent needs to coordinate the port transfer or ship change plan at the first time, to ensure that the goods arrive at the port within 15 days. In addition, the bill of lading endorsement must be operated in strict accordance with the requirements of the letter of credit. If the endorsement is inconsistent, it will lead to inability to pick up the goods, and the endorsement procedures need to be reprocessed, causing a delay of at least 3 days. **status:** suggested **Author:** Daniel Xu **Date:** 2026-08-12 ### Answer 4 Imported bolts can reduce capital occupation cost through the **VAT deferment** policy. Enterprises do not need to pay import value-added tax during customs clearance, but deduct it when declaring in the next month, which is equivalent to obtaining an interest-free capital period of about 2 months. However, two conditions need to be met: first, the enterprise is a general taxpayer, and second, the bolts are used for production and operation activities. In addition, if imported bolts come from countries that have signed free trade agreements with China, such as Germany, Japan, etc., you can enjoy tariff reduction and exemption benefits with the certificate of origin, and the tariff rate can be reduced from 8% to 0%. It should be noted that the certificate of origin must be submitted within 12 months after the export of the goods, and you will not be able to enjoy the preferential tax rate if it is overdue, resulting in additional tariff costs. **status:** suggested **Author:** Victor Sun **Date:** 2026-08-12 ### Answer 5 The collection and payment of foreign exchange for imported bolts must strictly comply with the compliance requirements for cross-border payment. If SWIFT remittance is adopted, the message must clearly indicate "payment for imported industrial bolts" to avoid being intercepted by the bank due to vague purpose. If CIPS RMB cross-border payment is adopted, you can enjoy lower handling fees and faster arrival speed, which generally takes 1-2 working days to arrive. In addition, enterprises need to keep documents such as foreign exchange collection and payment vouchers, procurement contracts, customs declaration forms for at least 5 years for the verification of the State Administration of Foreign Exchange. If the deviation between the foreign exchange payment amount and the amount on the customs declaration form exceeds 5%, a situation explanation needs to be submitted to the State Administration of Foreign Exchange, otherwise the subsequent foreign exchange collection and payment quota will be affected. **status:** suggested **Author:** Cindy Chen **Date:** 2026-08-12 ### Answer 6 When entrusting a Shanghai agent to import bolts, it is necessary to clearly stipulate the cargo right transfer node in the agency contract. It is recommended to set the cargo right transfer as "goods are released by customs and delivered to the designated warehouse", to avoid cargo right disputes caused by the bankruptcy of the agency company or other reasons. At the same time, force majeure clauses need to be added to clarify the party responsible for port detention fees and delay losses caused by force majeure such as epidemics and port strikes, which are generally borne by both parties 50% each. In addition, if the imported bolts involve intellectual property rights, it is necessary to file the intellectual property rights with the customs in advance, to avoid the goods being seized due to infringement, and the resulting storage fees and destruction fees shall be borne by the enterprise. **status:** suggested **Author:** Evelyn Li **Date:** 2026-08-12 ### Answer 7 If imported bolts are subject to customs control inspection, it is necessary to focus on cooperating with the customs to check whether the specifications, models and materials of the bolts are consistent with the customs declaration form. Especially for high-strength bolts, a tensile strength test report is required. In case of customs sampling inspection, the inspection cycle is generally 7-10 days, and storage fees need to be paid during the period. It is recommended to prepare a copy of the test report in advance to shorten the inspection time. In addition, it is necessary to pay attention to whether the packaging seal of the bolts is intact. If the seal is damaged, it is necessary to explain the situation to the customs at the first time, to avoid being identified as cargo damage or smuggling suspicion. If the inspection is unqualified, you can choose to return or rectify, and the rectification needs to be completed within 15 days, otherwise the goods will be destroyed. **status:** suggested **Author:** Jason Wu **Date:** 2026-08-12 ### Answer 8 From the perspective of supply chain, the procurement of imported bolts should be linked with the production plan of the enterprise. It is recommended to lock the shipping space 30 days in advance, to avoid cargo delay due to tight shipping space. At the same time, import risks can be reduced by establishing safety stock, which is generally set as the usage of 30 days. In addition, if you import bolts for a long time, you can sign an annual framework agreement with the agency company to enjoy more favorable agency rates and priority customs clearance services. You can also adopt the CIF trade term to entrust the transportation, insurance and other links to the agency company, reduce the operation links of the enterprise, and improve the supply chain efficiency. **status:** suggested **Author:** Grace Wang **Date:** 2026-08-12 ## Related Categories - [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/) - [Customs Declaration Q&A](https://www.sh-zhongshen.com/en/qa/cat-customs-declaration/) - [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": "Is the process of agent import of bolts in Shanghai complicated?
