How we work with B2B buyers
Plain terms for importers, dealers and contractors buying survey equipment from China.
- One unit is an order
- MOQ is one receiver or one set. Distributors get tiered prices from small quantities.
- Tested before it ships
- Each instrument is powered up and checked before packing. Ask for an outgoing-inspection video of your own unit.
- Your brand, if you want it
- OEM, ODM and OBM: logo, colours, packaging, manuals and software splash screens.
- Answers in hours
- Engineers reply on WhatsApp and email in English, with remote set-up help for the life of the product.
- Ready to export
- Commercial invoice, packing list and certificate of origin. Express, air or sea, quoted EXW, FOB, CIF or DAP.
- One-year warranty
- Parts and labour on instruments and accessories from the shipping date.
Checked on the bench, not just on the datasheet
Before dispatch we power up every receiver and total station, confirm satellite tracking, radio, Bluetooth and Wi-Fi, update firmware and pack the kit against your order.
On request we send a short outgoing-inspection video and the test record of your actual unit – so you know what is in the box before it leaves Shanghai.
How accurate will RTK be on your job?
RTK error grows with distance from the base or CORS station. Move the slider to see what to expect.
