Sourcing Water Repellent - Sodium Methyl Siliconate from Hangzhou Silway New Material Technology Co.ltd. - China Import Guide
Before placing an order, verify that the supplied ISO certification and REACH compliance are current and obtain the product’s safety data sheet. Confirm the HS Code 2905 classification and ensure the packaging size (200 L drum or IBC tote) matches your handling capacity. Request a sample batch if possible to assess compatibility with your substrates and to validate the supplier’s technical claims.
Discuss logistics early, specifying the preferred Incoterm such as FOB Hangzhou port or CIF Shanghai, and ask the supplier for an estimated lead time based on the chosen packaging volume. Because the supplier’s response rate is recorded as zero, obtain written confirmation of shipping schedules and payment conditions, typically a T/T advance payment or a letter of credit. Clarify any freight forwarder requirements and customs documentation needed for import into your country.
Arrange an independent inspection either pre‑shipment or at the loading port to verify container sealing and product volume. Request test results for water contact angle and shelf‑life stability to ensure the repellent meets your performance standards. Ensure the supplier provides a full set of documents, including the certificate of analysis, packing list, commercial invoice and bill of lading, to facilitate smooth customs clearance and quality assurance.
