Reliable sourcing and import agency services.
I am the business director of a foreign trade supply chain company. I just entered the imported waterproof materials agency business this year, and have two orders for waterproof membranes and sealants imported from the EU, with the client requiring delivery by the end of August 2026.
Now I’m facing multiple issues: First, I’m unsure whether the customs code classification for such materials is correct, and worry about price assessment problems. Second, I don’t know whether to choose direct shipping or transshipment for logistics, and am concerned about insufficient free detention periods and high demurrage fees.
Third, I have no idea about foreign exchange settlement and tax refund procedures, and fear violating compliance red lines. I now need a complete agency process guide from order acceptance to delivery, which can also help me avoid risks of customs seizure and cost overruns. Please provide a detailed explanation.

First，sort out the full-link compliant process for imported waterproof materials agency，covering four core stages from pre-preparation to final delivery. The first step is pre-document review: confirm the HS code of the imported waterproof materials first. Codes for products like waterproof membranes and sealants imported from the EU in 2026 may be adjusted slightly in line with EU Customs Union policies. It is recommended to conduct pre-classification via the Customs Single Window in advance，and prepare core documents including MSDS reports，EU Certificates of Origin，and third-party quality inspection reports. Focus on verifying the validity of the EU Generalized System of Preferences (GSP) Certificate of Origin. Eligible goods can enjoy tariff concessions，directly reducing import costs.
The second step is core logistics node coordination: choose direct shipping or transshipment plans based on order timeliness requirements. Prioritize direct shipping carriers for urgent orders to lock in cargo space and avoid container roll-offs due to overbooking，transshipment plans can be selected for bulk orders to cut costs. At the same time，clarify billing nodes for free detention periods and demurrage fees with logistics providers. It is recommended to use the CIF trade term and take full responsibility for logistics to avoid risks of losing control over cargo ownership.
The third step is full-process customs clearance control. In 2026，Shanghai Port has realized integrated online customs clearance. You can submit declaration documents via the Single Window in advance and arrange machine inspection to pre-judge inspection risks. If customs inspection is encountered，cooperate immediately to provide materials such as material test reports and supplier certificates to avoid additional costs caused by customs seizure and detention.
The fourth step is compliant settlement and tax refund. Prioritize the CIPS RMB cross-border payment channel for foreign exchange settlement to avoid exchange rate fluctuation risks，and ensure collection and payment processes meet cross-border compliance requirements. For the export tax refund link，strictly ensure consistency among invoice flow，capital flow，cargo flow and contract flow，and retain all customs declarations，transportation documents，and settlement vouchers. In 2026，the tax letter verification system has realized automatic online inspection. All filing documents need to be sorted out in advance for verification. Finally，establish an emergency plan: for example，apply for customs pre-ruling if there is an HS code dispute，apply for an extension of the free detention period if goods are detained at the port. Track logistics and customs clearance nodes throughout the process to ensure on-time order delivery and avoid various risks.

Regarding HS code classification for imported waterproof materials, focus on the product’s material, application and composition: for example, butyl rubber waterproof membranes used for building waterproofing should be classified under HS code 35069190, while polyurethane sealants fall under 35069110. In 2026, the EU has adjusted export tariffs for some waterproof materials, so verify that the cargo description on the Certificate of Origin matches that on the customs declaration.
If there is a customs price assessment dispute, provide official supplier quotations and import records of similar goods in the same period as evidence, and apply for price consultation. If a declaration error requires deletion and re-declaration, submit the application before goods are released to avoid port detention fees. Meanwhile, for high-value waterproof materials, apply for customs pre-ruling in advance to clarify classification and price assessment standards, reducing customs clearance risks.

The logistics plan for imported waterproof materials should be formulated based on cargo volume and timeliness: full-container load (FCL) goods should prioritize direct routes from Europe to Shanghai, with a voyage of about 28 days, reducing cargo damage and timeliness delays caused by transshipment; less-than-container load (LCL) goods can choose transshipment routes, cutting costs by around 30%, but require 7-10 days of transshipment lead time. Confirm with the shipping company that the free detention period is 14 days, and demurrage fees are about 80 euros per container per day.
If customs inspection is encountered, apply for an extension of the free detention period. The bill of lading should be properly endorsed to ensure compliant cargo ownership transfer, and clearly mark goods names such as "waterproof membranes" and "sealants" to avoid misdelivery at the discharge port.

Tax planning for imported waterproof materials should focus on the VAT deferral policy. In 2026, all EU member states support import VAT deferral, allowing businesses to temporarily avoid paying VAT at the time of import and declare and pay it when goods are sold later, effectively easing capital pressure.
Pay attention to the rationality of related-party transaction pricing to avoid triggering BEPS risks. If importing from EU related companies, provide contemporaneous documentation to prove pricing aligns with fair market value. Meanwhile, if royalties from non-resident enterprises are involved, withhold and pay withholding tax at a 10% rate, and conduct tax planning in advance.

Foreign exchange collection and payment for imported waterproof materials must meet cross-border compliance requirements. Prioritize the CIPS RMB cross-border payment channel to avoid exchange rate fluctuation risks and shorten settlement time to 1-2 working days. Ensure the cargo description in SWIFT messages matches that on the customs declaration to avoid account suspension caused by inconsistencies between foreign exchange transactions and customs declarations.
If using an offshore account for settlement, update account information regularly to meet CRS compliance requirements. Meanwhile, retain all foreign exchange collection and payment vouchers to ensure consistency among invoice, capital, cargo and contract flows, avoiding tax letter verification risks.

The contract for imported waterproof materials should clearly specify letter of credit (L/C) terms to avoid soft clause traps. For example, reserve sufficient customs clearance time for the beneficiary to provide third-party quality inspection reports.
In case of cargo damage or delayed delivery, require the supplier to provide a bank guarantee as compensation. Meanwhile, complete customs intellectual property protection filing.
If imported waterproof materials involve patent or trademark infringement, apply for customs protection in advance to avoid cargo seizure. In addition, the force majeure clause should clearly define exemption scopes for special situations such as epidemics and port congestion, reducing contract risks.

If on-site customs inspection is encountered, arrange a dedicated person to be present and cooperate immediately. First, check that the seal number matches the bill of lading to confirm goods have not been tampered with. Then cooperate with customs officers to conduct container unloading inspection, focusing on verifying that the quantity and material of goods match the declaration.
If abnormal machine inspection results are found, prepare third-party test reports in advance to prove goods meet declared standards. If testing is required, select a customs-recognized testing institution to ensure report timeliness and avoid customs clearance delays. Meanwhile, keep inspection records including photos and videos for future verification.

The packaging of imported waterproof materials must meet international transportation standards. Waterproof membranes should be packed in waterproof woven bags plus pallets, reinforced with stretch film to avoid moisture damage.
Sealants should be packed in sealed iron drums to prevent leakage, with warning signs such as "Moisture Proof" and "Keep Upright" marked on outer packaging. Prepare an MSDS report to clarify the product’s hazardous characteristics and emergency response measures.
In 2026, the EU requires all imported hazardous goods to provide compliant MSDS reports. Meanwhile, for transportation to high-humidity areas, place desiccants inside containers to enhance moisture-proof effects.

Tax refund for imported waterproof materials agency must strictly ensure consistency among invoice flow, capital flow, cargo flow and contract flow, with matching information across customs declarations, contracts, invoices, and foreign exchange settlement documents. In 2026, the export tax refund system supports online pre-declaration.
Complete pre-declaration within 15 days after goods are declared for export, then conduct official declaration after verification. Retain all filing documents including customs declarations, transportation documents, certificates of origin, and quality inspection reports for a 10-year retention period.
If tax letter verification is initiated, provide relevant supporting materials within 15 days, including supplier shipment records and internal sales records, to avoid tax refund delays. Meanwhile, pay attention to cross-month declaration timelines to ensure compliance with specified deadlines.
