Last week, 120 boxes of dried mangoes and puffed shrimp chips I ordered from Thailand and Malaysia arrived at Shanghai Port. The small freight forwarder I hired before suddenly told me there are format issues with my certificate of origin and health certificate, which may lead to customs detention. The cargo has been detained at the port for 3 days now, and the daily container detention charges and storage fees are rising. I am so anxious that I can barely eat, fearing that the cargo will be detained and I will have to pay high fines. Besides, this batch of goods is the main product for my National Day promotion, and if it arrives half a month late, all will be wasted. I would like to ask how I can carry out emergency remedies now? What procedures do I need to follow for formal imported snacks customs declaration in the future, and what common pitfalls can I avoid in advance? ## Answers ### Answer 1 — Best Answer First of all，for the current emergency of port detention，you need to launch the exception response plan immediately: submit a **document correction application** to the customs immediately，and entrust a qualified agency to re-review the format of the certificate of origin and health certificate -- you need to ensure that the product name and HS code on the certificates are completely consistent with those on the customs declaration form，and the health certificate must indicate the in-China registration number of the manufacturing enterprise. If the customs accepts the correction，you can apply for partial exemption of port detention fees，if not，you need to replace with compliant documents immediately and apply for deleting the original declaration and re-submitting the declaration，to avoid customs detention triggered by port detention exceeding 7 days. For subsequent formal imported snacks customs declaration，you need to follow the full-chain process: in the pre-declaration link，review all documents 7-10 days in advance，including certificate of origin，health certificate，packing list，invoice and contract，and focus on verifying the **accuracy of HS code classification** -- the HS code of snacks shall be accurately divided according to ingredients and processing technology，and wrong classification may trigger price review disputes. For core node connection，complete the pre-entry of the customs declaration form within 12 hours after the cargo arrives at the port，and submit electronic documents to the customs simultaneously to avoid missing the declaration window. Final compliance implementation shall ensure that the information on the customs declaration form，documents and cargo is completely consistent. After completing tax payment and inspection (if triggered)，pick up the cargo with the customs release notice. At the same time，all documents shall be retained for at least 3 years for subsequent customs inspection. **status:** accepted **Author:** Daniel Xu **Date:** 2026-10-25 ### Answer 2 HS code classification for imported snacks customs declaration is the core foundation of compliance. A common misunderstanding is to classify snacks generally only as "snacks", which shall be accurately divided according to the raw material proportion, processing technology and packaging form of the product. If there is a classification error, the customs will trigger a price review dispute. In minor cases, you will be required to pay the difference in tax, and in serious cases, the cargo will be directly detained and an inspection will be launched. In view of the current port detention situation, you can urgently apply for a pre-classification ruling from the customs, and complete document correction and customs declaration form modification quickly with the official ruling result to shorten the dispute resolution time. In addition, if you encounter a price review dispute later, you need to provide supporting documents such as procurement contracts, bank payment slips, and international market transaction price certificates of the same batch of products simultaneously, to avoid the customs levying tax based on the minimum price limit. **status:** suggested **Author:** Victor Sun **Date:** 2026-10-25 ### Answer 3 In view of the current 3-day port detention situation, you need to apply to the shipping company for extension of free storage period and free container usage period immediately. You can use the document correction acceptance notice issued by the customs as the application basis, and generally you can get an additional 3-5 days of free period to reduce container detention charges and storage costs. For subsequent logistics routes for imported snacks, direct routes shall be preferred. Transit routes are prone to problems such as cargo damage and document delay, and the storage fees at transit ports are higher. In addition, you need to clearly mark the note "priority release for food cargo" on the bill of lading. The shipping company will arrange port berthing and container pickup first, to avoid additional delays caused by container rolling. **status:** suggested **Author:** Evelyn Li **Date:** 2026-10-25 ### Answer 4 For imported snacks customs declaration, you can reduce capital occupation cost through the VAT deferral policy. You do not need to pay import VAT when the cargo is released, but deduct it in the subsequent VAT declaration period, which is equivalent to obtaining an interest-free loan for 3-6 months. It should be noted that three conditions must be met to apply for VAT deferral: first, the enterprise has the qualification of general taxpayer, second, the goods are used for taxable items, and third, the VAT deferral filing has been completed at the customs. In view of the current port detention situation, if you have not paid the tax yet, you can apply for VAT deferral simultaneously to reduce one-time capital expenditure. In addition, if the goods meet the rules of origin, you can enjoy the most-favored-nation tariff rate with a formal certificate of origin to reduce tariff costs. **status:** suggested **Author:** Cindy Chen **Date:** 2026-10-25 ### Answer 5 The receipt and payment of foreign exchange for imported snacks shall strictly comply with cross-border payment compliance requirements. You need to ensure that the cargo value on the customs declaration form is completely consistent with the payment amount, to avoid overpayment or underpayment, otherwise it will trigger an early warning from the State Administration of Foreign Exchange. In view of the current situation, if you have not completed the foreign exchange payment, you need to make the payment after the customs declaration form is finally confirmed; if you have already made the payment, you need to retain supporting documents such as payment slips and customs declaration forms for subsequent verification by the State Administration of Foreign Exchange. In addition, you can complete the payment through the CIPS RMB cross-border payment system, which not only has a more stable exchange rate, but also shortens the account arrival time, to avoid exchange losses caused by exchange rate fluctuations. **status:** suggested **Author:** Jason Wu **Date:** 2026-10-25 ### Answer 6 For the document problem caused by the current freight forwarder, you can check the service contract signed with the freight forwarder. If the contract clearly stipulates the document review obligation, you can claim compensation for losses such as port detention fees and storage fees from the freight forwarder. For subsequent imported snacks, you need to clearly stipulate in the procurement contract that the supplier shall provide certificates such as certificate of origin and health certificate that meet the requirements of Chinese customs. If losses such as customs detention and port detention are caused by unqualified documents, the supplier shall bear full responsibility. In addition, you need to complete the intellectual property customs protection filing in advance to avoid customs detention caused by infringement of imported snacks. **status:** suggested **Author:** Kevin Lin **Date:** 2026-10-25 ### Answer 7 If imported snacks trigger customs inspection, you need to prepare documents such as product composition test report and production process description in advance, and cooperate with the customs to complete the container unloading inspection. For products that are easy to get damp such as dried fruits and puffed snacks, you need to explain the packaging protection measures of the goods to the customs to avoid the sampling and inspection process triggered by suspicion of cargo deterioration. If the customs requires sampling and inspection, you need to cooperate in providing samples. The sampling and inspection cycle is generally 7-10 days, and you can apply for priority sampling and inspection to shorten the inspection time. In addition, you need to ensure that the actual packaging of the goods is completely consistent with the packaging description on the customs declaration form, to avoid customs detention caused by inconsistent packaging. **status:** suggested **Author:** Eric Zhou **Date:** 2026-10-25 ### Answer 8 The packaging of imported snacks shall comply with China's food safety standards and customs transportation requirements. For products that are easy to get damp and fragile such as dried fruits and puffed snacks, packaging materials with good moisture-proof and cushioning properties shall be used, and Chinese labels shall be marked on the packaging, including product name, ingredients, manufacturing enterprise information, shelf life and other contents. In view of the current port detention situation, if the cargo has damaged packaging, you need to apply to the customs for packaging rectification immediately, and entrust a qualified institution to complete the packaging replacement at the port, to avoid customs detention caused by unqualified packaging. In addition, you need to submit packaging samples to the customs for review in advance to ensure that the packaging meets compliance requirements. **status:** suggested **Author:** Grace Wang **Date:** 2026-10-25 ### Answer 9 The customs declaration process for imported snacks shall be linked with supply chain inventory planning. You need to complete document review and pre-declaration 15-20 days in advance to ensure fast release of the cargo after arrival at the port, to avoid sales disruption caused by insufficient inventory. In view of the current National Day promotion situation, you can adjust the subsequent procurement plan, give priority to suppliers who have completed compliance filing, and shorten the document preparation time. In addition, you can adopt the method of batch declaration, divide the goods into multiple batches for declaration, to avoid total sales loss caused by customs detention of the whole batch of goods, and reduce the compliance risk of a single declaration. **status:** suggested **Author:** Lucas Liu **Date:** 2026-10-25 ## 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 pre-declaration compliance audits are required before customs declaration for specialty snacks imported from all countries?", "text": "I am the owner of an imported snack shop that has been open for half a year.
