Last week, I just imported a batch of high-precision optical testing instruments worth 2 million from Germany. I chose a small customs brokerage company just to save money, but they failed to review the details of the certificate of origin and packing list in advance, which led to a customs hold on the cargo when it arrived at Yangshan Port. It has been detained at the port for 3 days now, with over 20,000 yuan in demurrage and detention fees incurred, and we also received a preliminary customs valuation notice from the customs. I am extremely anxious right now, worried that the long port detention will damage the precision of the instruments due to environmental issues, and also fear that more fees will be incurred later or even lead to full customs detention. I would like to ask if there are any import customs brokerage companies in Shanghai that can solve this emergency situation, have rich experience in import customs clearance, especially capable of handling precision instrument imports and customs valuation disputes, and preferably can help me recover some of the losses already incurred? ## Answers ### Answer 1 — Best Answer First，it is necessary to expose common industry misconceptions: many cargo owners choose small brokerages without formal qualifications or pre-review processes lured by low prices. These brokerages often skip the document pre-review step and submit declarations directly to customs. Although this seems to save costs，it actually hides huge risks. The chain of negative reactions from this operation will quickly escalate: the certificate of origin discrepancy you encountered will directly trigger a customs hold，leading to detention and demurrage fees. If the corrections are not made within 3 days，the cargo may be transferred to a bonded warehouse，where fees will double，and the high-precision instruments may suffer precision loss due to substandard temperature and humidity in the warehouse，even triggering customs valuation disputes and extending the clearance period to more than 10 days. Physical risk isolation measures should focus on **72-hour advance document pre-review** and **on-site emergency response capabilities**: choose a brokerage company with 20 years of industry experience，which will check the consistency and compliance of all documents including certificate of origin，packing list，and commercial invoice in advance，and immediately contact foreign suppliers to correct any problems found，avoiding customs holds after the cargo arrives at the port. Exclusive loss mitigation tip: The brokerage can assist in applying to the port for demurrage fee reduction (for cases of first-time violations and quick corrections)，while contacting on-site customs officials to explain the precision requirements of the cargo and apply for priority processing channels to minimize losses. **status:** accepted **Author:** Lucas Liu **Date:** 2026-10-18 ### Answer 2 Regarding the preliminary customs valuation notice you received, you need to sort out all the genuine transaction documents for the imported instruments immediately, including purchase contracts, bank remittance slips, commercial invoices issued by the original manufacturer, technical service agreements, etc. Ensure that the product names, models, prices, and origin information on all documents are completely consistent to form a logical closed loop. If the customs questions the transaction price, you can provide import customs declarations for the same model of instruments at Shanghai port in the past 6 months as reference price basis, to avoid being directly assessed at the customs reference price. If declaration amendment and re-submission is required, ensure that the origin information marked on the corrected certificate of origin completely matches the actual origin of the cargo, to avoid triggering customs audit warnings again and shorten the clearance period. **status:** suggested **Author:** Cindy Chen **Date:** 2026-10-18 ### Answer 3 For the high-precision optical testing instruments currently detained at the port, first coordinate with the brokerage to apply to the shipping company for an extension of the free detention period. If the shipping company does not approve, you can temporarily transfer the cargo to a bonded warehouse with constant temperature and humidity conditions to avoid precision deviation of the instruments due to temperature and humidity fluctuations in the open port environment. At the same time, strictly control the compliance of the bill of lading endorsement to ensure that the cargo ownership is always in your hands during the clearance period, avoiding cargo ownership transfer due to brokerage operational errors. For future imports, you can choose direct shipping routes to Shanghai Yangshan Port to reduce transit links and the risk of document errors, and make an appointment for customs clearance number 3 days in advance to ensure that the cargo enters the clearance process immediately upon arrival at the port. **status:** suggested **Author:** Daniel Xu **Date:** 2026-10-18 ### Answer 4 The detention and demurrage fees incurred in this import can be included in the relevant costs of the dutiable value of the imported goods, and deducted when declaring import value-added tax, reducing the overall tax cost. At the same time, if your company has the qualification of general VAT taxpayer, you can apply for the import VAT deferral policy, which means you do not need to pay import VAT immediately upon clearance, but pay it uniformly in the next month's VAT declaration, effectively easing the cash flow pressure of the enterprise. In addition, you can verify whether the high-precision optical testing instruments belong to the category of advanced equipment encouraged by the state for import. If eligible, you can apply to the customs for tariff reduction to further reduce import costs. **status:** suggested **Author:** Eric Zhou **Date:** 2026-10-18 ### Answer 5 The 2 million payment for this import must ensure that the payment and receipt path is compliant. If the previous payment was made through an offshore account, you need to supplement the correspondence between the payment voucher and the purchase contract to avoid triggering verification warnings from the State Administration of Foreign Exchange. For future imports, it is recommended to use the CIPS RMB cross-border payment system for payments, which can not only avoid exchange losses caused by USD exchange rate fluctuations, but also simplify the payment and receipt review process and improve compliance. At the same time, all import documents (including customs declarations, certificates of origin, commercial invoices, and payment slips) must be archived for at least 5 years for subsequent verification by the State Administration of Foreign Exchange and customs. **status:** suggested **Author:** Victor Sun **Date:** 2026-10-17 ### Answer 6 Regarding the dispute with the small brokerage this time, you can first sort out the agency service contract previously signed. If the contract does not clearly specify that the brokerage shall bear the losses of detention and demurrage fees caused by document review errors, you can try to negotiate with the brokerage to bear part of the losses. When choosing a brokerage company in the future, you need to clearly stipulate the scope of responsibility for document review, the processing time limit for abnormal situations, and specific standards for loss compensation in the contract, and add a force majeure clause as a fallback to avoid liability disputes caused by unforeseen changes in customs policies. In addition, you can require the brokerage to provide a performance bond to ensure that it has the ability to bear economic losses caused by operational errors. **status:** suggested **Author:** Kevin Lin **Date:** 2026-10-17 ### Answer 7 If the customs launches an on-site inspection of your high-precision optical testing instruments, you need to prepare the technical specifications and original manufacturer's inspection report of the instruments in advance, to avoid inspectors blindly opening the boxes due to lack of understanding of the instrument structure, which may damage the internal precision components of the instruments. At the same time, verify the authenticity of the container seal. If the seal is found to be damaged or has abnormal signs, immediately ask the brokerage to contact the shipping company to verify the container transportation situation, to avoid being identified as a tampered container. In addition, you can apply for customs to use machine inspection instead of manual unpacking inspection, reducing the time the instruments are exposed to non-standard environments and reducing the risk of damage. After passing the machine inspection, the cargo can directly enter the clearance process, greatly shortening the inspection time. **status:** suggested **Author:** Evelyn Li **Date:** 2026-10-17 ## 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": "Which reliable professional import customs brokerage company with 20 years of industry experience is available in Shanghai?", "text": "I am a procurement manager at a small and medium-sized enterprise specializing in precision testing equipment in Shanghai.
