Importers should first verify that the lock’s zinc‑alloy housing complies with the destination country’s fire‑rating and electromagnetic compatibility regulations. Request the supplier’s CE or equivalent test reports, as well as any firmware version documentation, to ensure the product meets local safety standards. Any deviation from the advertised specifications must be confirmed in writing before shipment.
When arranging logistics, clarify whether the transaction will be under FOB or CIF terms and identify the preferred Hong Kong port for loading. Typical lead times for production and packing are 20‑35 days after order confirmation, but exact timelines should be agreed with the supplier. Payment can be made by L/C or T/T; align the payment schedule with your financing cycle and request a pro‑forma invoice detailing all costs.
Prior to dispatch, organise a third‑party inspection focusing on mechanical dimensions, battery installation and functional testing of all access methods. Insist on a copy of the inspection report and the supplier’s Certificate of Analysis for the electronic components. Proper documentation will facilitate customs clearance and protect the buyer against non‑conformities once the locks arrive at the destination.
