Reliable sourcing and import agency services.
I am the Purchasing Manager of a large domestic municipal engineering company. Recently, I have undertaken a cross-border supporting waterproofing project and need to import a batch of polymer waterproofing membranes and sealants from the EU.
On my first attempt to import waterproofing materials, I was detained by Shanghai Customs due to incomplete documents, and the detention fees alone cost over 20,000 yuan, which also delayed the construction schedule. Now I want to find a professional import agency, but I don’t know how to proceed specifically.
From pre-preparation to customs clearance and subsequent foreign exchange settlement and tax refund, is there a complete process? I am also worried about valuation disputes and compliance risks, as well as how to control overall costs not exceeding the budget. Can you explain the practical details clearly?

First，complete pre-document review: The 2026 Customs Pre-classification System has realized online one-click submission，and the pre-classification conclusion will be issued within 3 working days. It is necessary to confirm the HS code of waterproofing materials in advance，for example，polymer waterproofing membranes are classified under 3907990090，and sealants under 35069190. Meanwhile，prepare a full set of compliance documents: Certificate of Origin (zero tariff can be enjoyed if applicable under the China-EU Free Trade Agreement)，manufacturer's quality inspection report，MSDS，ocean bill of lading，freight and insurance premium vouchers，complete document pre-audit 30 days in advance to avoid detention due to document non-compliance.
Core link connection stage: After overseas pickup，choose direct shipping routes to avoid transshipment ports and reduce cargo damage risks. Apply to the shipping line for a 14-day free detention period plus a 7-day free container demurrage period to reduce port congestion costs. For customs clearance，declare through the National Customs Integration System，related party transactions need to provide contemporaneous documentation to prove that the pricing complies with the arm's length principle to avoid valuation disputes. If it is an AEO Advanced Certification agency，it can enjoy policy benefits such as priority customs clearance and 50% reduction in inspection rates.
Abnormal contingency plans shall be deployed in advance: If inspected by customs，prepare the technical parameters of the goods and manufacturer's certificates in advance to cooperate with the inspection，if it involves hazardous goods sealants，provide UN packaging certification report in advance. If there is a declaration error，you can apply for deletion and re-declaration through the electronic customs before release without additional fees.
Final compliance landing stage: Use CIPS Digital RMB for foreign exchange settlement to lock in exchange rates and avoid fluctuation losses，retain a full set of documents for 6 years for future inspection. Ensure the consistency of goods flow，document flow，capital flow，and contract flow. The import VAT deferral policy has been fully implemented in 2026，and no advance payment is required，which can be directly deducted as input tax later，further optimizing capital occupation.

Choosing direct shipping routes can avoid cargo damage and delay risks at transshipment ports; there are 3 direct shipping routes per week from the EU to Shanghai Port, with a voyage of about 14 days. The agency needs to sign a rate agreement with the shipping line and apply for a 14-day free detention period plus a 7-day free container demurrage period to reduce port congestion costs. In terms of cargo ownership control, it is recommended to use a straight bill of lading to avoid the risk of unbladed delivery of goods.
If transshipment is required, confirm the handling efficiency and customs inspection rate of the transshipment port, and prioritize transshipment ports with inspection rates below 8%. Transportation packaging must comply with international maritime standards; waterproofing membranes must be wrapped with moisture-proof plastic films, packed on wooden pallets, and marked with IPPC to avoid quarantine issues with wooden packaging.

Cross-border settlement with Digital RMB has been fully popularized in 2026; the agency can assist clients in completing foreign exchange settlement through the CIPS system, with arrival time 2-3 days faster than SWIFT and lower handling fees. It is necessary to ensure "who settles foreign exchange receives the goods" to avoid settling foreign exchange to third parties and ensure the consistency of capital flow and goods flow.
Forward foreign exchange settlement and sale can be used to lock in exchange rates and avoid exchange rate fluctuation risks. Meanwhile, foreign exchange settlement vouchers, customs declarations and other documents must be retained for inspection by foreign exchange management authorities to ensure compliance with foreign exchange receipts and payments.

The customs inspection rate is about 10%; if selected, the agency needs to coordinate with the cargo owner in advance to prepare the technical parameters of the goods, manufacturer's quality inspection report and other documents. Confirm that the seal number is consistent with the bill of lading to avoid inspection delays caused by seal damage or inconsistent numbers.
If hazardous goods are involved, provide UN packaging certification report and MSDS in advance to cooperate with the customs to complete the hazardous goods inspection. If problems are found during inspection, communicate with the customs in time and provide supplementary explanation materials to avoid detention of goods.

The import business must ensure the consistency of goods flow, document flow, capital flow and contract flow; the agency shall assist clients in retaining a full set of documents for 6 years for future inspection. If a tax inquiry is received, provide transaction vouchers, foreign exchange settlement vouchers and other materials in time to prove the authenticity of the business.
For imported waterproofing materials for engineering use, the engineering contract shall be retained to prove the actual use of the goods and avoid being identified as domestic sales goods. Tax authorities have realized electronic document inspection in 2026, and relevant data can be directly retrieved through the electronic customs without submitting paper materials.
