Last month, I imported 2 containers of dried mango from Thailand for the first time. I chose a small agency for the low price, whose initial quotation was 20% lower than the market price. However, after the cargo arrived at the port, they suddenly added a lot of extra charges including port detention fee, expedited inspection service fee, etc. My total expenditure was 30% over budget, and I almost got the cargo detained due to missing document review, which would have delayed the replenishment schedule for 11.11 pre-sale and caused me great losses. Now one container of my frozen dried durian will arrive at Yangshan Port, Shanghai in 3 days, with a cargo value of about 80,000 RMB. I am really afraid of falling into the same trap again. I want to ask clearly: what exactly are the charging details for agency customs clearance? Are there any hidden fees? Can you give me a clear quotation matching my cargo condition, and tell me how to avoid the risk of temporary extra charges? ## Answers ### Answer 1 — Best Answer First of all，it should be clarified that the core of the low-price trap of traditional small agencies is "split charging": they only quote the basic customs declaration fee，and hide the cost of mandatory services such as document review，inspection assistance，emergency response for port detention，etc. This eventually leads to total expenditure overrun of 30%-50%，and even triggers consecutive losses from customs detention and port congestion，which directly affects the replenishment schedule of e-commerce pre-sale. For your frozen dried durian (80,000 RMB cargo value，entering via Yangshan Port)，we adopt a **fully transparent itemized quotation** model，and charges are divided into three parts: basic customs declaration service fee (including system entry and customs declaration)，document compliance review fee (including verification of certificate of origin and health certificate)，and on-site assistance fee (including inspection accompaniment and manifest verification). There are no hidden charges at all. The total quotation is about 0.8%-1.2% of the cargo value，which is 640-960 RMB. Meanwhile，your cargo value meets the access threshold of **VAT Deferral Mode** at Shanghai Port (cargo value below 1,000,000 RMB，belongs to ordinary food category). You do not need to pay import VAT in advance，and can defer payment until the tax declaration period，which directly frees up approximately 10,400 RMB in cash flow (calculated based on 13% VAT rate)，offsetting customs clearance service costs while improving capital turnover. Finally，our cost control tip for you: when signing the agency agreement，you must clearly specify the clause of "all charging details are listed，no temporary extra charges"，and require the agency to complete document pre-review 72 hours in advance，to avoid port detention fees caused by document issues，and completely avoid the low-price trap. **status:** accepted **Author:** Eric Zhou **Date:** 2026-10-18 ### Answer 2 For your frozen dried durian, note that in the customs valuation process, the basic agency customs clearance service fee does not include the cost of handling valuation disputes. If Customs questions your cargo value, you need to provide supporting materials such as purchase contracts, payment certificates, certificate of origin, etc. If the agency does not inform you in advance, extra valuation defense service fees may be incurred. Our service includes pre-valuation review, we check the difference between your cargo value and the Customs reference price in advance to avoid subsequent disputes, and this cost is already included in the basic quotation, no extra payment is required. In addition, if your cargo involves transfer from bonded area to domestic sales, customs clearance fees need to additionally account for the service cost of bonded verification. However, your current shipment is direct import, so this item does not need to be considered. **status:** suggested **Author:** Jason Wu **Date:** 2026-10-18 ### Answer 3 Agency customs clearance fees at Shanghai Yangshan Port need to combine the connection cost of the logistics chain. If your cargo goes directly into the bonded warehouse after arrival, the customs clearance fee includes the service cost of manifest data synchronization; if you pick up the container directly to an urban warehouse, container pickup fee and short-haul fee need to be calculated additionally, but these fees belong to the logistics link, not the customs clearance agency's charges. We will confirm manifest information with your freight forwarder in advance to ensure seamless connection between customs clearance and container pickup, avoiding container detention fees caused by delayed manifest, and this emergency connection service is already included in the on-site assistance fee, no extra payment is required. **status:** suggested **Author:** Daniel Xu **Date:** 2026-10-18 ### Answer 4 For agency customs clearance under VAT deferral mode, there is no special difference in charging, but attention should be paid to tax accounting compliance. Your frozen dried durian has a cargo value of 80,000 RMB, which meets the access requirements for VAT deferral at Shanghai Port (cargo value below 1,000,000 RMB, belongs to ordinary food category). We will assist you in submitting the VAT deferral application during customs clearance, and this service is already included in the document review fee. In addition, under VAT deferral mode, you need to pay import VAT within the tax declaration period, and late payment will incur late fees. We will send you a tax payment reminder 7 days in advance to avoid extra costs. **status:** suggested **Author:** Andy Guo **Date:** 2026-10-18 ### Answer 5 Agency customs clearance fees include the service cost of payment and collection compliance. If you use RMB cross-border payment via CIPS, we will assist you in checking SWIFT message or CIPS message information to ensure that payment and collection information matches the customs declaration information, and this service is already included in the basic customs declaration service fee. In addition, if your cargo qualifies for preferential tariff via certificate of origin, we will assist you in submitting the certificate of origin for electronic review to ensure you get the most-favored-nation tariff rate, and this service is also included in the document review fee, no extra payment required. **status:** suggested **Author:** Michael Zhang **Date:** 2026-10-18 ### Answer 6 Agency customs clearance fees include the cost of drafting compliance agreements. The core of the temporary extra charge problem you encountered before is that charging details and breach clauses were not clearly specified in the agreement. Our agency agreement clearly lists all charging items, amounts, payment schedules, and the clause that "any temporary extra charge must be notified 72 hours in advance, otherwise the client has the right to refuse payment". It also includes the liability division clause for customs detention and port congestion. If customs detention is caused by the agency's mistake, the agency will bear losses including port detention fee, container rental fee, etc. This legal service is already included in the basic quotation. **status:** suggested **Author:** Grace Wang **Date:** 2026-10-18 ### Answer 7 Agency customs clearance fees at Shanghai Yangshan Port include the cost of on-site inspection assistance. Your frozen dried durian belongs to food category, and the Customs inspection rate is about 15%. If devanning inspection is required, we will assist you in coordinating the inspection site and providing cargo description, and this service is already included in the on-site assistance fee. In addition, if non-compliant packaging is found during inspection, we will assist you in submitting the rectification application, and this service is also included in the abnormal handling cost, no extra payment required. We will pre-check the compliance of cargo packaging in advance to avoid inspection rectification costs caused by packaging issues. **status:** suggested **Author:** Victor Sun **Date:** 2026-10-18 ### Answer 8 Your frozen dried durian is cold chain cargo, and agency customs clearance fees do not include the cost of packaging rectification. However, we will assist you in reviewing packaging compliance in advance to ensure it meets the requirements of Customs and cold chain transportation. If your cargo uses disposable frozen packaging, a packaging material certificate is required. We will assist you in submitting this certificate to Customs, and this service is already included in the document review fee. In addition, if packaging damage occurs during transportation, we will assist you in submitting an abnormal declaration, and this service is also included in the on-site assistance fee, no extra payment required. **status:** suggested **Author:** Linda Gao **Date:** 2026-10-18 ### Answer 9 From the perspective of supply chain cost, agency customs clearance fees need to be considered in combination with overall inventory turnover cost. Your current shipment of frozen dried durian is for e-commerce pre-sale, so customs clearance timeliness directly affects inventory turnover. Our service includes an expedited customs clearance option: if you need to complete customs clearance within 24 hours, an extra expedited service fee is required, but this fee can be waived by submitting documents for pre-review 3 days in advance. In addition, we will provide you with a linkage analysis of customs clearance timeliness and inventory turnover to help you optimize replenishment schedule and reduce inventory backlog cost. **status:** suggested **Author:** Kevin Lin **Date:** 2026-10-18 ## 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/) - [Customs Declaration Q&A](https://www.sh-zhongshen.com/en/qa/cat-customs-declaration/) - [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": "How Large Is the Fee Difference for Agency Customs Clearance of Imported General Cargo, Dangerous Goods and Prepackaged Food?", "text": "I am an e-commerce owner of imported snacks based in Shanghai.
