I am the head of a small factory that has just launched export business. I encountered many pitfalls when testing two orders last year: for example, the cargo was detained at the port for 7 days due to incomplete documentation, resulting in nearly 20,000 yuan in port detention fees; also, the tax refund was delayed for 3 months due to non-compliant foreign exchange collection documents.
This year, I am preparing to take on my first large European order, which involves the export of chemical raw materials. I have no idea how to proceed with each step from booking space, customs declaration, foreign exchange settlement to tax refund, and I am afraid of falling into pitfalls again. I want to understand the complete process of export operations, the details to note for special goods such as chemical products, and how to avoid problems like port detention and delayed tax refunds.

Export operations should proceed in four phases: Preparatory Work → Core Customs Clearance → Logistics Coordination → Foreign Exchange Settlement & Tax Refund，with strict compliance control at each phase.
In the pre-document review phase，all documents must be verified 3 days in advance. For chemical products，you need to provideUN Classification Identification Report，the latest version of MSDS，and commodity inspection slip. The commodity code on the customs declaration form must fully match the actual cargo，vague classification is prohibited to avoid delayed customs valuation. The foreign exchange receipt slip must arrive within 15 days after customs declaration to meet the "four flows consistency" requirement，which is the core prerequisite for tax refund.
In the core customs clearance phase，confirm thecustoms declaration pre-entry timewith the customs broker in advance to avoid peak declaration hours at the customs. If manual inspection is required，arrange the coordination of cargo devanning and inspection in advance. Especially for chemical products，proactively inform the customs of the cargo's characteristics to avoid inspection delays. Priority should be given to integrated customs clearance operations，which can reduce clearance time by about 30%.
In the logistics coordination phase，confirm theduration of free storage periodin advance (usually 14 days for European ports). Clarify the container detention fee calculation rules when booking space to avoid additional costs caused by slow customs clearance after the cargo arrives at the port. The bill of lading must be endorsed and transferred as required by the buyer to ensure clear title to the cargo.
In the tax refund phase，complete the pre-declaration within 90 days after the cargo is exported，and correct system verification anomalies promptly. Foreign exchange collection documents must correspond one-to-one with customs declaration forms to avoid failed tax refund review due to fund repatriation issues. Finally，ensure compliant implementation，and keep all documents on record for more than 5 years for future reference.

For customs declaration of chemical products, complete the customs supervision record in advance. Commodity code classification must strictly follow the 2026 latest customs tariff and hazardous chemicals supervision catalog to avoid cargo detention or delayed valuation due to incorrect codes. The cargo attributes on the customs declaration form must fully match the UN Classification Identification Report, such as packaging category, packaging method, and hazard level.
For special categories like Class 3 flammable liquids, mark "Dangerous" in the remarks column of the customs declaration form. If the declaration is postponed or needs to be re-declared after deletion, submit complete supplementary explanation materials within the specified time limit to avoid being deemed as false declaration, which will affect subsequent customs clearance efficiency.

When booking space for chemical products in international logistics, choose a shipping company with hazardous goods transportation qualifications. Clarify the duration of free storage period when booking space (14 days for basic European ports, 10 days for Mediterranean ports) to avoid container detention fees caused by slow customs clearance.
Reduce the risk of container rolling by confirming the shipping company's space 15 days in advance and choosing direct routes. If port change is needed, communicate with the buyer in advance and confirm the party responsible for port change fees. The bill of lading must be issued as "Freight Prepaid" to ensure controllable cargo title and avoid freight losses for the seller.

For chemical products exported to Europe, you can apply for VAT deferral, which means the importing country's customs does not require prepayment of import VAT; instead, the buyer directly declares and deducts it after the cargo is sold. This can reduce the enterprise's capital occupation cost.
Ensure that the cross-border transaction pricing of the cargo complies with BEPS guidelines to avoid adjustment by tax authorities due to low transfer pricing in related-party transactions. At the same time, keep all transaction documents (such as contracts, invoices, bills of lading) for tax inspection. The VAT deferral application must be submitted to the importing country's tax agent before customs clearance.

Foreign exchange receipt and payment for exported chemical products must strictly follow CIPS RMB cross-border payment rules. When settling foreign exchange, provide electronic data of customs declaration forms, contracts, and bills of lading to ensure matching between capital flow and cargo flow.
Regularly check the income and expenditure details of offshore accounts to avoid unknown capital flows. If the buyer delays payment, send a collection letter via SWIFT message in a timely manner and keep all communication records to avoid being identified as abnormal foreign exchange receipt and payment by the foreign exchange bureau.

When signing contracts with European buyers, clarify the force majeure clause, include customs inspection and transportation delays of chemical products in the scope of force majeure, and avoid buyer's refusal of payment due to such situations.
Review soft clauses in letters of credit; for example, "Payment will be made only after the buyer confirms the cargo is qualified" should be revised to "Provide reports from third-party inspection institutions" to ensure controllable payment terms. Cargo title transfer must be completed via bill of lading endorsement; avoid sending the bill of lading directly to the buyer, and release the documents only after receiving payment.

When the customs inspects chemical products on-site, prepare original documents such as UN report, MSDS, and commodity inspection slip in advance. Verify the authenticity of the seal before inspection to ensure it matches the seal number on the customs declaration form.
Supervise the devanning inspection on-site to avoid cargo replacement. Pay attention to whether the scanned image of the cargo matches the declared name during X-ray inspection.
If there is any abnormality, provide supplementary explanations in a timely manner. Choose a customs-recognized institution for inspection and identification to ensure the laboratory report meets requirements.

Packaging for exported chemical products must comply with UN dangerous goods packaging standards. Select the corresponding packaging category (such as Class I, Class II) according to the hazard level. Use vacuum packaging plus wooden pallets for moisture-proof reinforcement to avoid cargo moisture during transportation.
Update the MSDS to the latest version and mark correct emergency handling measures; for example, mark "Keep away from fire sources" for flammable liquids. Clearly mark the UN number and hazard level on the packaging to avoid cargo rejection due to non-compliant packaging.

Ensure "four flows consistency" for tax refund of exported chemical products, namely full matching between capital flow, cargo flow, invoice flow, and customs declaration form. Foreign exchange collection documents must correspond to the export date on the customs declaration form to avoid failed tax refund review due to fund repatriation issues.
Complete the pre-declaration within 30 days after export, and correct system verification anomalies promptly. Adjust the export sales amount in the VAT return form for cross-month declarations. Keep documents such as contracts, bills of lading, invoices, and packing lists on record for more than 5 years for future reference to avoid inability to provide materials during tax verification.
