从China供应商批发进口3/4" To 12" Camlock Coupling / Quick Connector — FOB条款
Sourcing 3/4" to 12" Camlock Coupling / Quick Connector from Happy Technology & Development Co., Ltd. - China Import Guide
Before placing an order, verify that Happy Technology & Development Co., Ltd. can supply the exact size, material, and thread combination required, as the catalogue focuses on 1/2 inch to 6 inch with 3/4 inch to 12 inch offered more broadly. Request a current material test certificate sample for stainless steel 316 to confirm it meets your project's corrosion resistance requirements. Ask for dimensional inspection data against A-A-59326 or DIN2828, particularly if you need guaranteed interchangeability with existing inventory. Confirm gasket elastomer options and whether they meet FDA, EC 1935/2005, or specific chemical compatibility standards for your application.
Logistics and lead time must be confirmed directly with the supplier, as no standard delivery period is stated. Tianjin is a major northern Chinese port with established container and bulk freight routes, so FOB Tianjin or CIF terms to your destination are typical negotiating points. Clarify Incoterms, whether the quoted price includes export packing in plywood crates or cartons, and who arranges marine insurance. Payment terms often range from 30 percent deposit with balance against BL for established buyers to 100 percent advance for new relationships, though the supplier's specific policy must be confirmed. Given the zero response rate recorded, initiate contact well ahead of your procurement timeline and establish a backup communication channel such as WeChat or direct telephone.
Quality assurance on arrival should include dimensional spot checks against A-A-59326 gauge requirements, thread fit testing with certified gauges, and visual inspection for casting defects such as porosity, cold shuts, or incomplete filling. For stainless steel orders, verify grade with a portable XRF analyser or request independent third-party inspection. Pressure test a sample to 1.5 times working pressure if the application is critical. Retain one coupling from each batch for future reference and potential metallurgical analysis. Documentation to collect includes packing list, commercial invoice, certificate of origin, and any material or test certificates agreed during negotiation.
