I recently purchased 20 tons of non-seed use chia seeds from South America, and the cargo ship will arrive at Shanghai Port next week. I heard from peers that document omission led to one week of port detention and nearly 10,000 RMB in container detention fees, so I am very anxious now. I want to know what core documents I need to prepare specifically? What standards will customs refer to for valuation during customs declaration? How should I respond if I encounter on-site inspection? Is there a way to avoid these risks in advance to let the goods clear customs smoothly? ## Answers ### Answer 1 — Best Answer Chia seed import customs declaration should start with pre-document review. First confirm that the product is classified under HS code 1207.9999 (for non-seed use)，core documents include commercial invoice，packing list，bill of lading，certificate of origin (for tariff preference if applicable)，phytosanitary certificate，and entry animal and plant quarantine permit (pre-packaged products additionally require label filing certificate).**Pre-review should focus on verifying document consistency**，such as matching between invoice amount and bill of lading weight，and normalization of the seal on the certificate of origin. In terms of core node connection，complete electronic declaration 3 days before the cargo arrives at the port. It will be directly released after document review is approved，if there is any query，customs will issue an inspection notification. At this time，you need to communicate with the customs broker and on-site staff in time to ensure the inspected goods are consistent with the declaration description.**Abnormality contingency plans cover document correction and inspection response**: missing documents need to be supplemented within 48 hours，prepare samples and supporting documents in advance before inspection. Final compliance clearance requires obtaining customs declaration form and tax payment proof after paying customs duty and VAT. If you apply for VAT deferral，you need to file with the tax authority in advance and provide qualification documents such as business license and import & export right certificate.**It is recommended to cooperate with a professional agency**，such as Zhongshen. Its 20-year experienced team can review documents in advance and optimize procedures to avoid port detention risks. In addition，attention should be paid to label compliance. Labels of pre-packaged chia seeds must comply with China's national food safety standards，and mark ingredients，net content，production date and other required information. If the label does not meet the requirements，it needs to be rectified at the site designated by customs before re-declaration. **status:** accepted **Author:** Evelyn Li **Date:** 2026-06-03 ### Answer 2 When conducting customs valuation for chia seed import declaration, customs usually adopts the transaction value method: it is based on the actually paid or payable price, with adjustments for freight, insurance premium and other expenses. If the declared price is lower than the market price of the same type of products in the same period, you need to provide supplementary materials such as purchase contract, payment voucher, and cost accounting sheet. If you cannot prove the authenticity of the price, customs will re-assess the price by deductive value method (deducting profit, taxes and other items from domestic selling price) or computed value method (cost + profit + freight), and the enterprise needs to pay additional tax. It is recommended to learn about the recent valuation range of the same product in advance to ensure a reasonable declared price. **status:** suggested **Author:** Linda Gao **Date:** 2026-06-02 ### Answer 3 The selection of logistics routes for chia seed import needs to balance cost and timeliness. Direct voyage to Shanghai Port is fast (about 30 days) but high in cost, transiting via Singapore can reduce freight by 15% but takes 5 more days. The free storage period after cargo arrival is 7 days, and container detention fee is charged at USD150/container/day starting from the 8th day. It is recommended to apply to the shipping company for an extension of 1-3 days of free storage period in advance. If customs clearance delay is expected, you can entrust the customs broker to apply for container detention fee reduction. Endorsement transfer of bill of lading requires all seals to be complete to avoid obstruction of cargo title transfer. **status:** suggested **Author:** Daniel Xu **Date:** 2026-06-02 ### Answer 4 The VAT deferral policy for chia seed import applies to general taxpayer enterprises. The application requires providing business license, import & export right certificate, VAT declaration forms for the latest 3 months, and bank account opening permit. After filing is approved, VAT can be deferred for payment during import (up to 3 months), which eases capital pressure. However, it should be noted that enterprises need to maintain good tax credit during the deferral period. If there is late declaration or tax arrears, the deferral qualification will be canceled and late payment surcharge will be required. It is recommended to consult a tax advisor before application to evaluate whether your qualification meets the requirements. **status:** suggested **Author:** Lucas Liu **Date:** 2026-06-02 ### Answer 5 Foreign exchange receipt and payment for chia seed import must comply with foreign exchange management regulations. When settling foreign exchange, provide customs declaration form, commercial invoice, bill of lading and other materials to ensure consistency between capital flow and goods flow. When using CIPS for RMB cross-border payment, the message must accurately fill in the payee name, account number, amount and transaction code (101010). For offshore account management, check the income and expenditure records regularly, avoid transactions with sensitive countries/regions to prevent account freezing. It is recommended to conduct a monthly self-inspection of foreign exchange compliance to ensure the legality of the receipt and payment process. **status:** suggested **Author:** Jason Wu **Date:** 2026-06-02 ### Answer 6 The chia seed import contract must clearly stipulate the force majeure clause. If cargo arrival delay is caused by natural disasters or policy changes, the division of responsibilities should be agreed (e.g. the seller bears the upper limit of port detention fee at USD5000). Avoid soft clauses in letter of credit terms, such as "inspection certificate issued by the buyer's designated institution", such clauses can easily lead to failure of negotiation. Intellectual property filing must be completed in advance. If the packaging involves patents/trademarks, provide relevant supporting documents to avoid infringement risks. It is recommended to have the contract reviewed by legal counsel before signing to eliminate potential legal loopholes. **status:** suggested **Author:** Andy Guo **Date:** 2026-06-02 ### Answer 7 During on-site inspection of chia seed import, customs will check the packaging, label, quantity and quality. For damaged packaging, you need to provide a repair certificate; for labels that do not meet national standards, you need to re-label. Tips for machine inspection: place the goods neatly, avoid covering key parts such as production date. If the goods are sent for laboratory testing, you need to wait for the test report (about 3-5 days), preparing samples in advance can shorten the identification time. After inspection, if qualified, customs will release the goods; if unqualified, you need to re-declare after rectification. It is recommended to arrange a dedicated person to be present to cooperate during inspection, and answer customs questions in a timely manner. **status:** suggested **Author:** Victor Sun **Date:** 2026-06-02 ### Answer 8 Chia seeds are easily damp, so the packaging should use aluminum foil bags (moisture-proof grade IPX7) plus five-layer corrugated cartons, with UN3499 moisture-proof mark affixed on the outside. MSDS must clearly specify physical indicators such as moisture content ≤8%, particle size ≥95%, and storage conditions (cool and dry place). Use 5cm thick pearl cotton as cushioning material to reduce collision damage during transportation. The packaging must be marked with product name, quantity, origin, shelf life and other required information to meet customs requirements. It is recommended to entrust a third-party testing agency to verify packaging compliance before packaging. **status:** suggested **Author:** Michael Zhang **Date:** 2026-06-02 ## 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 Documents Are Required for Chia Seed Import Customs Declaration?", "text": "I am the head of a trading company that has just entered the chia seed import business.
