Fireproof magnesium oxide board
Sourcing Fireproof Magnesium Oxide Board from Chengdu Onekin Import & Export Co., Ltd. - China Import Guide
Verify the fire rating documentation with the supplier, as Grade A claims require third-party test certificates under ASTM E119 or EN 13501-1. Request batch-specific test reports for moisture absorption and bending strength. Ensure the product is labeled with production date and batch number for traceability. Avoid accepting boards with visible cracks or delamination, as these indicate poor curing.
Logistics are typically shipped from major Chinese ports under FOB or CIF terms. Lead time is 20 to 30 days from order confirmation, depending on production load. Packaging is palletized with edge protectors and plastic wrapping. Confirm whether the supplier handles export documentation and if insurance is included under CIF terms. Payment is commonly 30% deposit with 70% against BL copy.
Conduct a pre-shipment inspection for dimensional accuracy, surface finish, and edge integrity. Use a digital caliper to measure thickness at multiple points across the sheet. Check for efflorescence or salt bloom on the surface, which indicates unreacted MgCl2. Retain a sample for comparison upon arrival. Request a certificate of conformity and fire test report before final payment.
