Last month, the small agent I hired missed the application for the Customs Clearance Form for Inward Goods, which led to a 3-day port detention of the whole container of Dutch milk powder. I spent more than 22,000 yuan extra on port detention fees and warehouse rent, and almost missed the restocking node for the 618 pre-sale. I was so anxious that I stayed up for three consecutive nights to monitor the logistics information. Now I want to switch to a professional import agency, but I have not fully understood the potential risks of import agency before. I would like to ask what are the most common pitfalls and high-frequency problems in the full link of import agency from the core perspectives of cost control, compliance risk, cargo right security and process connection? ## Answers ### Answer 1 — Best Answer Common industry misconceptions fall into three categories: First，some small and medium-sized agents omit the pre-link of document pre-review to grab orders，and even promise "all-inclusive customs clearance" to skip compliance procedures，Second，they confuse cargo title documents，replacing original ocean bills of lading with house bills of lading，Third，they hide hidden costs and pass on expenses such as port detention fees and warehouse rent to customers. These misconceptions will trigger a chain of negative reactions: If the document pre-review is omitted，and the application for core documents such as the Customs Clearance Form for Inward Goods and Certificate of Origin is missed，it will directly lead to port detention of goods. For ordinary containers at Shanghai Port in 2026，the daily charge will be about 1200 yuan from the 3rd day of port detention. If no rectification is made after more than 10 days，the goods may be seized by customs，and even the auction process will be initiated，If a house bill of lading is used，the agent can dispose of the goods without permission，and merchants will face the risk of losing both goods and payment，The transfer of hidden costs will make the actual import cost 20%-30% higher than the budget，squeezing the profit margin of small and medium-sized merchants. Physical risk isolation measures include: First，require the agent to submit all documents 7 days in advance for **preliminary pre-review** to ensure that all documents meet the latest requirements of customs，Second，insist on requesting original ocean bills of lading and refuse to accept house bills of lading without cargo title guarantee，Third，require the issuance of **double-title customs declaration form** to ensure that merchants directly hold customs compliance certificates. Exclusive loss stopping tips: It is clearly agreed in the agency contract that if port detention lasts more than 24 hours due to the agent's mistake，all port detention fees and warehouse rent shall be borne by the agent，At the same time，the agent is required to pay a cargo title deposit equivalent to 10% of the cargo value and deposit it into a joint escrow account of both parties. If there is a cargo title dispute，compensation can be deducted directly from the deposit. **status:** accepted **Author:** Lucas Liu **Date:** 2026-10-30 ### Answer 2 Common valuation disputes in the customs clearance process of import agencies are mainly concentrated in three dimensions: First, the agent fails to prepare complete valuation supporting materials in accordance with customs requirements, and only submits the customs declaration form to declare customs clearance, leading to customs questioning the authenticity of the declared price; Second, they confuse dutiable value with e-commerce retail price and procurement cost price, and incorrectly declare the procurement price excluding freight and insurance premium as the dutiable value; Third, they fail to go through the procedures of pre-classification and pre-valuation in advance, and cannot provide effective defense basis when encountering customs valuation adjustment. In response to these problems, it is necessary to collect and sort out a full set of supporting materials such as procurement contracts, bank payment slips, certificates of origin, international freight invoices and other supporting materials 7 days before declaration, to ensure that the declared price is consistent with the actual transaction price; If high-value goods or sensitive categories are involved, you can apply to the customs for pre-valuation in advance to lock the dutiable value range and avoid the risk of port detention caused by temporary valuation. **status:** suggested **Author:** Linda Gao **Date:** 2026-10-30 ### Answer 3 Common omissions in the logistics connection link of import agencies include: First, choosing routes with too many transshipments to reduce logistics costs, leading to a more than 30% increase in the probability of cargo being rolled over and port detention; Second, the duration of free storage period and free detention period are not clearly agreed in the logistics contract. For ordinary containers at Shanghai Port in 2026, the free storage period is generally 7 days. If the agent fails to apply for extension in advance, the daily container detention fee is about 800 yuan per day after exceeding the period; Third, the authenticity of container seals is not verified during cargo title handover, leading to an increased risk of goods being swapped or lost during transportation. To solve these problems, it is necessary to lock in direct routes or routes with no more than 1 transshipment in advance, and require the agent to clarify the duration of free storage period, free detention period and extension application process in the logistics contract. Within 24 hours after the arrival of the goods, verify that the seal number is consistent with that indicated on the bill of lading. If any abnormality of the seal is found, the cargo damage claim process shall be initiated immediately. **status:** suggested **Author:** Victor Sun **Date:** 2026-10-30 ### Answer 4 Common tax problems involved in import agencies mainly include: First, failing to reasonably apply for the VAT deferral policy, leading to merchants paying import value-added tax in advance, occupying cash flow for 30-60 days; Second, the agent fails to accurately distinguish between the dutiable value of tariffs and the tax calculation base of value-added tax, and incorrectly includes tariffs in the VAT deduction scope, leading to abnormal tax declaration; Third, failing to handle the tariff reduction corresponding to the certificate of origin in time, leading to overpayment of 10%-30% of tariffs. In response to these problems, it is necessary to confirm in advance whether the goods meet the tariff reduction conditions of free trade agreements such as RCEP, and require the agent to submit the certificate of origin to apply for tariff reduction before customs declaration; At the same time, under the VAT deferral policy of Shanghai Customs in 2026, eligible general taxpayers can apply for deferred payment of value-added tax without advance payment during customs clearance. It is necessary to provide the agent with general taxpayer qualification certificate and deferral application materials in advance to ensure compliant tax declaration and optimal cost. **status:** suggested **Author:** Jason Wu **Date:** 2026-10-30 ### Answer 5 Common compliance problems in the payment and collection link of import agencies include: First, the agent does not operate in accordance with the "four-flow consistency" principle, that is, the contract flow, capital flow, invoice flow and goods flow do not match, leading to the tax authority initiating letter verification, which affects the payment and collection quota for subsequent import business; Second, they fail to choose compliant cross-border payment channels. Some small agents use offshore accounts for payment and collection of foreign exchange, facing the risk of being listed on the watch list of the State Administration of Foreign Exchange; Third, they fail to handle import foreign exchange payment verification in time, leading to the freezing of merchants' foreign exchange quota. In response to these problems, the agent is required to use the CIPS RMB cross-border payment system for foreign exchange payment to ensure that the capital flow is fully consistent with the contract flow and invoice flow; At the same time, the import foreign exchange payment verification shall be completed within 15 days after the customs clearance of goods to avoid restrictions on foreign exchange quota. If large amount foreign exchange payment is involved, it shall be filed with the State Administration of Foreign Exchange in advance. **status:** suggested **Author:** Evelyn Li **Date:** 2026-10-30 ### Answer 6 Common legal problems involved in import agencies mainly include: First, the agency contract does not clearly stipulate the transfer node of cargo title ownership. Some agents stipulate in the contract that "cargo title will be transferred only after the payment for goods is received", leading to merchants being unable to pick up the goods even if they have paid the full payment; Second, the letter of credit issued by the agent on behalf of the merchant has soft clauses, such as requiring the provision of "inspection certificate not signed by the buyer", leading to merchants being unable to meet the payment conditions and the payment for goods being frozen; Third, the fallback clause for force majeure is not stipulated in the contract, such as who shall bear the port detention fee caused by port strike. In response to these problems, it shall be clearly stated in the agency contract that "after the goods arrive at the port and the customs declaration is completed, the cargo title shall be transferred to the merchant immediately". At the same time, the agent is required to submit all clauses for review before issuing the letter of credit to delete all soft clauses; In addition, a force majeure fallback clause shall be added, stipulating that the extra costs caused by unforeseen factors such as port strikes and customs policy adjustments shall be shared by both parties at a ratio of 5:5. **status:** suggested **Author:** Cindy Chen **Date:** 2026-10-30 ### Answer 7 Common omissions in the on-site inspection link of import agencies include: First, the agent fails to sort out the full set of materials required for inspection before the arrival of the goods, such as MSDS, certificate of origin, import license, etc., leading to failure to provide them in time during customs inspection and delaying the inspection duration; Second, they fail to operate in accordance with customs requirements when dealing with unpacking inspection, such as moving goods without permission, leading to customs suspecting that the goods are in violation of regulations and initiating a second inspection; Third, they fail to interpret the content of the inspection notice in time, such as failing to notice the inspection items required by customs, leading to the detention of goods. In response to these problems, the agent is required to sort out the full set of inspection materials 3 days before the arrival of the goods and store them in the data cabinet designated by the port; During the unpacking inspection, customs staff shall lead the operation, and the agent is only responsible for cooperation; After receiving the inspection notice, the interpretation shall be completed within 24 hours. If inspection items are involved, a third-party testing institution shall be contacted in advance to ensure that the inspection process meets customs requirements. **status:** suggested **Author:** Andy Guo **Date:** 2026-10-30 ## 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": "What are the high-frequency risk issues in full-link import agency operation that require advance planning and avoidance?", "text": "I am the owner of a small and medium-sized e-commerce company in Shanghai focusing on imported maternal and infant products.
