Talk to a Trade ExpertI am in the building materials trading business. Recently, a European client wants to order 10 tons of insulating glass sealant and needs an export agency but has no prior knowledge of the process. Previously, I tried a freight forwarder who stated that the sealant's MSDS did not meet the requirements, almost leading to detention.
Now the client is pressing hard for delivery, fearing delays to the order. I want to know how to conduct compliant export agency procedures, what documents are required, which logistics options to choose, whether tax refund is available, and what pitfalls must be avoided.

When handling the export agency of insulating glass sealant，first clarify its core attributes: In 2026 customs classification，solvent-based products fall into Class 3 flammable liquids，which must be operated in strict compliance with dangerous goods regulations—this is the premise of all subsequent procedures.
Three key points must be grasped in pre-submission document review: First，the 16th edition GHS MSDS，which must be issued by a CNAS-accredited institution，clearly specifying the flash point (usually ≤60℃) and UN number (UN1133)，Second，the dangerous goods packaging identification report，confirming that the packaging meets UN standards (e.g。a 200L steel drum must provide drop/leakage test reports)，Third，the commodity code—solvent-based products fall under 3207300000，and non-solvent-based products fall under 3214100000. Incorrect classification will directly lead to order rejection.
Key node coordination must be strictly monitored: For logistics，book dangerous goods cabin space 7 days in advance，prioritizing direct voyages (e.g。Shanghai→Rotterdam takes 25 days) to avoid refusal by transshipment ports，For customs declaration，declare via the Single Window and simultaneously upload the DG declaration form—if machine inspection shows abnormalities，provide component test reports as required，For tax refund，ensure consistency of four key documents (contract，invoice，logistics document，and receipt of payment certificate). In 2026，some regions allow VAT deferral to reduce capital occupation.
Abnormality response plans must be implemented in advance: For port detention，apply for extending the free detention period to 10 days (the standard for dangerous goods is 7 days)，During inspection，verify packaging labels (flammable liquid label，UN number) to avoid detention due to missing labels，For missing documents，complete qualification documents within 3 working days—delays will incur late declaration fees (0.05% of the total amount per day).
Final compliance implementation must confirm: Take photos of packaging labels before loading containers，note "dangerous goods" on the bill of lading，declare tax refund within 15 days after receipt of payment，and have the agency track all nodes throughout to ensure no omissions.

For customs declaration of insulating glass sealant export, pay attention to commodity code classification—silicone-based solvent-based products fall under 3207300000, and non-solvent-based products fall under 3214100000. Incorrect classification may trigger price verification disputes. In 2026, customs implements "declare before inspection" for dangerous goods—upload MSDS, packaging identification report, and DG declaration form via the Single Window.
If price verification fails, provide the contract and third-party price certificates (e.g., industry association quotations) to avoid taxation based on the minimum price. Submit a secondary declaration within 72 hours; delays will incur late declaration fees, so it is recommended to pre-review documents 3 days in advance.

Insulating glass sealant is a Class 3 dangerous goods—submit DG booking 7 days in advance for cabin reservation, specifying UN1133, flash point, and Class II packaging. Prioritize direct voyages for logistics (Shanghai→Rotterdam takes 25 days); confirm that transshipment ports accept Class 3 dangerous goods (e.g., Singapore Port allows it).
For dangerous goods, the free time for containers is 7 days (10 days for ordinary goods), and late return of containers incurs a daily fee of USD 150 per TEU. Issue a straight bill of lading and note "dangerous goods"—otherwise, the destination port will refuse discharge.

In 2026, the export tax refund rate for insulating glass sealant is 13%—must ensure consistency of four key documents (contract, invoice, logistics document, and receipt of payment certificate). For CIF terms, deduct freight and insurance premiums for tax calculation; for FOB terms, use the FOB value as the basis.
Shanghai and Shenzhen implement VAT deferral—VAT is exempt on export and paid by the importing country. Declare tax refund within 15 days after receipt of payment; explain cross-month delays. Ensure reasonable pricing for related-party transactions to avoid suspension of tax refund due to profit transfer.

Receipt of payment must be conducted via CIPS/SWIFT—unjustified offshore receipt is prohibited in 2026. The difference between the receipt of payment and the customs declaration amount must be ≤5%; if exceeded, provide an explanation.
Choose forward hedging for exchange rate fluctuation avoidance. Prepayments must be registered as "advance receipt of payment" with SAFE and cancelled within 180 days after export. Confirm that the client country has no sanctions (e.g., EU sanctions on some Middle Eastern countries).

The agency contract must clearly specify: The agency is responsible for customs declaration, logistics, and tax refund; the client is responsible for qualified documents and goods. Add a force majeure clause (e.g., port strikes, policy changes) for exemption.
Avoid soft clauses in letters of credit (e.g., payment after client confirmation of quality)—it is recommended to attach a pre-quality acceptance report. Cargo ownership transfers after bill of lading endorsement to avoid transferring ownership before payment. Register intellectual property rights (if any patents exist) to prevent detention due to infringement.

Packaging must comply with UN standards—200L steel drums or 18L plastic pails for Class 3 dangerous goods, providing CNAS-accredited packaging performance test reports. Ensure clear labels: Flammable liquid label (GB190), UN1133, Class II packaging, and manufacturer name.
Add foam cushioning before loading containers; place 10 packages of desiccant in a 20-foot container to prevent moisture damage. For bulk cargo, use dangerous goods pallets and do not mix with ordinary goods.
