Repeat-order clarity
Use documented commercial grades, approved part references and defined acceptance criteria. Batch quantities and consolidated shipments are quoted against actual supplier availability and packing.
Quality requirements
Specify material traceability, dimensional inspection and applicable pressure or leakage testing. Filters require an efficiency basis; chemicals require a grade-specific TDS, SDS and COA. Documentation is confirmed per order.
Packing & delivery
Protect threads, sealing faces and filter media. Confirm packed dimensions, gross weight and container limits. FOB and destination delivery are quoted by shipment; DDP availability requires the destination ZIP and an agreed import arrangement.
