I am a factory producing daily chemical raw materials. This year, I have just expanded into overseas orders in Southeast Asia and Europe. Half of the goods to be shipped this time are general non-dangerous plant extract liquids, and there are two containers of low-danger chemical additive liquids.
Previously, I engaged two small agents. The last shipment was rejected by the shipping company because the packaging did not meet standards, resulting in a loss of slot fees. Last week, another batch was detained at the port for a week because the MSDS composition labeling was unclear, generating tens of thousands in demurrage charges.
Now I am unclear about the specific processes required for different categories of liquid exports, what documents to prepare, and how to operate to avoid these pitfalls while controlling overall costs. I would like to consult on specific operational methods.

First，complete the preliminary classification review based on the hazardous properties of the goods. General non-dangerous liquids require a non-dangerous appraisal report issued by a commodity inspection agency. Low-danger/dangerous liquid goods require a UN Dangerous Goods Classification Appraisal Report and an MSDS. During the review，verify that the composition labeling is completely consistent with the actual goods to avoid detention and inspection due to inconsistent composition declarations.
The core nodes are packaging verification，space booking，customs declaration，and shipment loading. The packaging stage must match the cargo attributes. Non-dangerous liquids must meet waterproof and leak-proof requirements for sea/air freight packaging. Dangerous liquid goods must use UN-marked packaging of the corresponding level. Apply to the shipping company for dangerous goods space 7 working days in advance to avoid rejection due to lack of space.
Regarding contingency plans，reserve a 3-day buffer for customs clearance in advance. If customs sampling occurs，cooperate immediately to provide supplementary appraisal materials. If the shipping company rejects the loading，coordinate with ports nationwide to quickly transfer the port and reship to reduce demurrage losses.
At the final implementation stage，ensure consistency across goods，certificates，documents，and invoices. Synchronize with the import requirements of the destination country in advance，and arrange shipment only after confirming all compliance items meet the requirements. Track cargo status throughout the process to ensure smooth shipment and customs clearance，avoiding unnecessary extra losses.

Match corresponding packaging parameters based on the liquid's danger level and mode of transport. General non-dangerous liquids can choose conventional IBC tons or galvanized drums; stacking tests and leakage tests must be performed in advance to confirm no leakage will occur during transport. Low-danger dangerous liquids require packaging corresponding to the UN code; the packaging surface must clearly print the UN number and danger attribute markings.
Wooden packaging requires fumigation or heat treatment and a fumigation certificate. All packaging must be sent to a designated agency in advance for performance testing; only after passing the test can it be used for loading, thereby avoiding the risk of shipping company rejection at the source.

Organize originals and electronic copies of all declaration documents in advance and place them in a conspicuous position inside the container door for easy access during customs inspection. Before machine scanning, adjust the stacking method of the goods to avoid multi-layer liquid packaging blocking the scanning view, which triggers manual unstuffing inspections.
If inspection and appraisal are required, prepare the composition test report issued by the original factory in advance, cooperate with customs staff to complete sampling, and shorten the cycle for issuing the assay report to avoid long detention periods generating high extra costs.

During the declaration stage, classify truthfully according to the actual attributes of the goods. Liquids with different attributes cannot be declared together; general non-dangerous liquids and dangerous liquids must be declared separately.
If there are doubts about price review, prepare materials such as purchase contracts, payment vouchers, and original factory invoices in advance to prove the authenticity of the transaction price and cooperate with customs to complete the price review verification. If a customs system warning is encountered, supplement corresponding supporting materials immediately to avoid deleting and re-declaring, which would delay the shipping schedule.

For liquid exports, prioritize shipping companies with qualifications for handling special cargo and lock in space in advance. For dangerous liquid shipments, space generally needs to be booked 10 days in advance to avoid overbooking and container rolling. If transshipment is required, prioritize ports at the transshipment hub that have dangerous goods handling qualifications to avoid cargo detention at the transshipment port.
Apply for corresponding free storage time and free detention time from the shipping company in advance to reduce potential extra costs. Track container dynamics throughout the process and notify the consignee in advance to prepare for customs clearance before arrival.

Foreign exchange collection and payment for liquid exports must be declared declared truthfully according to the actual transaction amount. In 2026, CIPS RMB cross-border payment will cover more European, American, and Southeast Asian routes; RMB settlement can be chosen to avoid exchange rate fluctuation risks.
If a third-party agent is used for collection and payment, a compliant agency agreement must be signed to ensure the capital flow matches the cargo flow, avoiding violations of foreign exchange control requirements. When settling exchange, choose off-peak settlement to optimize the exchange rate for purchase and settlement, reducing exchange losses.

For liquid export tax rebates, ensure consistency across the four flows: cargo flow, capital flow, invoice flow, and contract flow. Organize export customs declarations, purchase and sales contracts, input invoices, and collection vouchers in advance to complete document filing.
If a tax letter inquiry is encountered, prepare corresponding transaction proof materials in advance and cooperate to complete the inquiry verification. Tax rebate declarations for general liquids and dangerous liquids must be filed separately to avoid declaration errors affecting tax rebate receipt. Perform a pre-declaration verification before shipment to eliminate common declaration errors.
