Verify the counterparty and the machine separately
A real company and an attractive machine listing answer different questions. Request the seller's legal company details and compare them with the contracting entity and invoice. Separately ask for a current view of the machine, its nameplate and its location. At TIANSEN CNC, the legal company is Dongguan Tiansen Machinery Co., Ltd.; use the contact details on this website to discuss a listing.
Turn promises into a written scope
Keep the advertisement, quotation and agreed accessory list. Specify the exact unit, known condition, currency, payment milestones, delivery scope and acceptance arrangements. If a spindle option, rotary table or bar feeder is essential, require it to be identified in the quotation. Do not rely on a broad model-family brochure to establish the equipment fitted to a used machine.
Treat changed payment instructions as a separate check
Before paying, verify beneficiary details through a previously established contact channel. If bank details change unexpectedly, pause and verify them independently with the contracting party. Avoid sending money solely on the strength of an urgent message. Agree any inspection, escrow or other payment arrangement directly; none is implied by the presence of a website or WhatsApp button.
Compare total purchase scope
Request an itemized explanation of packing, dismantling, loading, inland transport, insurance and international freight where these are relevant. Ask your own forwarder and customs broker to review the proposal. A lower machine price may represent a different configuration or exclude services in another quote. No checklist removes every transaction risk, but clear evidence makes differences visible before commitment.
Use an evidence-based shortlist
For each candidate keep three lists: confirmed facts, missing information and acceptance requirements. Reject comparisons built on invented manufacture years or assumptions about options. The DMU 50 eVo and AWEA LP-3021 inquiry listings, for example, require further machine details before a substantive equipment comparison. Ask for those details first, then decide whether inspection and a formal quotation are worthwhile.
