Standard production lead time is 25-35 days after deposit and confirmation of all details. Customized orders may need 35-45 days. Sea freight transit time depends on your port; we arrange FOB, CIF or door-to-door delivery as required.

Every unit is calibrated and passes function and accuracy checks against reference standards before packing. Housings use durable ABS or stainless steel, sensors and load cells are life-cycle tested, and batteries are certified. Our factory runs ISO 9001 quality management and our products carry CE certification.

Each unit is packed in a retail box or export carton with foam protection; cartons are palletized on request. We optimize carton dimensions for container loading and provide full shipping documents including packing list, invoice, certificate of origin and fumigation certificate.

Please tell us the models or specifications you need (for example a diamond tester pen, a 0.01 g precision balance or a portable gas analyzer), order quantity, destination port, and any customization such as logo, color or packaging. With these details we normally send a detailed quotation within 24 hours.
