Last month, I tried to import a batch of facial masks from South Korea for the first time, and ran into many troubles: I filled in the wrong HS code, the goods were detained by customs for 3 days, and I incurred more than 2000 in port detention fees. The logistics provider I hired claimed it was a direct voyage, but it was transshipped temporarily and arrived one week late, leading to stock-out in my store and a loss of more than 50000 in sales. I heard from a friend that export tax refund can cut costs, but I have no idea how to operate it, and I am afraid of being investigated for filling wrong information. I originally thought that handling import and export by myself could save agency fees, but now I have spent more unnecessary money and wasted a lot of time. I want to ask why I must hire an import and export agency? Can't I handle these processes by myself? ## Answers ### Answer 1 — Best Answer For cross-border e-commerce sellers，the full-link compliance and efficiency of import and export processes directly affect costs and delivery. Take the wrong HS code you encountered as an example，it seems like a minor problem，but it will actually trigger chain reactions such as customs valuation disputes and port detention fees. Professional agencies will conduct pre-document review at the order confirmation stage: for example，for beauty products，they need to check the product ingredient list to match the correct HS code (e.g. facial masks should be classified under 33049900 instead of 33041000)，and at the same time verify the authenticity and validity of the certificate of origin and health certificate，to avoid goods detention caused by incomplete or incorrect documents. The connection of core nodes is the core value of an agency. For example，the linkage between customs declaration and logistics: the agency will synchronize the pre-approved declaration form to the logistics provider in advance，ensuring that the declaration is completed 24 hours before the cargo arrives at the port，reducing the risk of port detention. If abnormalities such as incorrect coding occur，the agency can quickly submit a modification application through the customs "tolerance mechanism"，which is usually resolved within 12 hours，much faster than the 3-5 days it takes for enterprises to handle it on their own. In addition，agencies will establish an abnormal response plan database，for example，for quarantine inspection of beauty products，they will prepare samples and test reports in advance to shorten inspection time. In the compliance implementation link，the agency can help you complete the full-process management of export tax refund. For example，**electronic filing of documents** requires archiving materials such as customs declaration forms，invoices，bills of lading，and logistics documents in accordance with tax requirements，to avoid tax refund failure caused by incomplete filing. At the same time，the agency will monitor the tax refund progress and respond to tax correspondence surveys in a timely manner to ensure that tax refund funds arrive on time. Through full-link refined operations，agencies can help you reduce more than 80% of process errors and cut extra costs such as port detention fees and fines. **status:** accepted **Author:** Kevin Lin **Date:** 2026-08-27 ### Answer 2 The accuracy of HS code is the core of customs declaration compliance. Common mistakes made by enterprises when self-filing include: confusing product functions (e.g. classifying facial masks as skincare products instead of cosmetics), ignoring ingredient proportions (e.g. alcohol-containing beauty products need to be classified under different codes). The correct procedure is: first query the preliminary code through the General Administration of Customs "Commodity Information Service Platform", then combine information such as product ingredient list, production process and use, entrust a professional institution to conduct pre-classification, and obtain the Pre-classification Decision Letter to ensure the authority of the code. If incorrect coding has already caused goods detention, you need to immediately submit a Correction Application, and attach supporting materials such as product test reports and supplier instructions, to strive for quick approval by customs. In addition, you should pay attention to preventing valuation disputes during customs declaration: prepare purchase contracts, commercial invoices, payment receipts, certificates of origin and other materials in advance to prove that the declared price is consistent with market conditions, and avoid excessively high customs valuation. **status:** suggested **Author:** Jason Wu **Date:** 2026-08-27 ### Answer 3 Cost control of cross-border logistics needs to start from two aspects: route optimization and risk avoidance. For the transportation of beauty products on the Japan-South Korea route, prioritize direct shipping companies (e.g. Hanjin Shipping, COSCO Shipping). Direct shipping is usually 2-3 days faster than transshipment, and can reduce the risk of cargo damage during transshipment. Port detention fees are mostly caused by customs declaration delays, so you need to confirm the cargo arrival time with the agency in advance to ensure that the customs declaration form is pre-approved 24 hours before arrival. If port detention fees have already been incurred, you can apply to the shipping company for an extended free storage period. Usually, providing a pre-approval certificate of the customs declaration can extend the period by 1-2 days. In addition, correct endorsement of the bill of lading is crucial: if the FOB trade term is adopted, the bill of lading must be blank endorsed by the shipper, to avoid the inability to pick up goods caused by incorrect endorsement. For high-value beauty products, it is recommended to choose full container load transportation and use a container with intact seal to reduce the risk of theft. **status:** suggested **Author:** Eric Zhou **Date:** 2026-08-27 ### Answer 4 Small and medium-sized foreign trade enterprises can enjoy the **VAT deferral** policy through import and export agencies to ease capital pressure. Take imported beauty products as an example: if you import on your own, you need to pay 13% value-added tax during customs clearance; while applying for VAT deferral through an agency can delay the VAT payment time to the sales link, which is equivalent to obtaining an interest-free loan for 3-6 months. In terms of export tax refund, agencies can help enterprises optimize their tax structure: for example, register the tax refund subject in a park with tax refund preferences to increase the tax refund ratio; at the same time ensure the "consistency of four flows" (contract flow, capital flow, logistics, invoice flow), to avoid the tax authority rejecting the tax refund application due to inconsistent flows. In addition, for small-volume and multi-batch exports of cross-border e-commerce, agencies can assist in handling tax refunds under the "9710" or "9810" model, simplifying the declaration process. **status:** suggested **Author:** Andy Guo **Date:** 2026-08-27 ### Answer 5 Cross-border payment and collection compliance is the key for enterprises to avoid tax and foreign exchange risks. Import and export agencies will guide enterprises to conduct payment and collection through formal channels: for example, using the CIPS RMB Cross-border Payment System, which not only has fast arrival speed (usually 1-2 working days), but also avoids foreign exchange control risks caused by using third-party payment platforms. During settlement, agencies can provide exchange rate optimization services: for example, choose exchange rate locking based on market conditions to lock in losses caused by exchange rate fluctuations. In addition, for small-value collection of cross-border e-commerce, agencies can assist in applying for a "personal foreign exchange settlement account", but it should be noted that the annual limit per person is 50,000 US dollars, and the excess part must be settled through an enterprise account. Complete transaction vouchers such as order screenshots, logistics documents, and invoices must be retained during payment and collection for inspection by the State Administration of Foreign Exchange. **status:** suggested **Author:** Cindy Chen **Date:** 2026-08-27 ### Answer 6 Risk clauses in international trade contracts should be avoided in advance. For example, for logistics delays, the contract should clearly specify "if the delay is caused by the carrier, the shipper shall bear a penalty of 0.5% per day", and specify a reliable shipping company. For intellectual property protection of beauty products, you need to complete Intellectual Property Customs Protection Filing with the General Administration of Customs in advance. After filing, customs will actively monitor infringing goods, to avoid enterprises being detained for selling infringing products. In addition, you should pay attention to soft clauses when paying by letter of credit: for example, a clause such as "the bill of lading must indicate the name of the freight forwarder designated by the buyer" will lead to loss of control of cargo rights, and should be modified to "the bill of lading indicates the freight forwarder designated by the seller". If you encounter force majeure (such as logistics interruption caused by the pandemic), you need to issue a force majeure certificate in a timely manner and negotiate with the buyer for delayed delivery to avoid breach of contract damages. **status:** suggested **Author:** Victor Sun **Date:** 2026-08-27 ### Answer 7 The focus of compliance review for export tax refund is the authenticity and consistency of documents. Enterprises need to ensure that the information on customs declaration forms, special VAT invoices, collection vouchers, and logistics documents are completely consistent: for example, the product name on the customs declaration form must be consistent with that on the invoice, and the collection amount must match the declared amount. The agency will assist the enterprise to establish a **electronic document filing system**, scan and upload all tax refund materials, and store them for at least 5 years for correspondence surveys by tax authorities. If a tax correspondence survey is conducted, materials such as purchase contracts, production records, and logistics vouchers must be provided within 15 days to prove that the business is authentic. In addition, for the "tax exemption without invoice" policy for cross-border e-commerce, three conditions must be met: first, the enterprise is registered in a cross-border e-commerce comprehensive pilot zone; second, the goods are exported through the customs of the comprehensive pilot zone; third, no special VAT invoice is obtained. Agencies can assist enterprises to apply for this policy and simplify the tax refund process. **status:** suggested **Author:** Lucas Liu **Date:** 2026-08-27 ## 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": "Can Import and Export Agency Solve Customs Declaration Code Errors for Cross-Border E-Commerce?", "text": "I run a cross-border e-commerce business, mainly selling Japanese and South Korean beauty products.
