Company and factory identity
- Is the supplier the actual manufacturer, a trading company, or an authorized sales office?
- Can they show a business license, factory address, and product scope that matches the machine?
- Do workshop photos or videos show the actual machine type you are buying?
- Do they manufacture, assemble, or only resell the equipment?
Machine configuration
- What controller, servo, spindle, rails, screws, turret, tool changer, chiller, or laser source is included?
- Are the quoted component brands and models written into the quotation or contract?
- Which accessories are included and which are optional?
- What power, air, gas, coolant, foundation, or installation requirements exist?
Performance and acceptance
- What tolerance or accuracy is claimed, and how will it be tested?
- Can the supplier run a sample part or demonstration relevant to your use case?
- Will they provide inspection videos, photos, reports, or third-party inspection access before balance payment?
- What happens if the machine fails the agreed acceptance test?
Warranty and service
- How long is the warranty and what is excluded?
- Who pays for replacement parts, shipping, remote support, or on-site service?

Export and payment

- Are deposit, balance payment, and inspection milestones clearly tied to deliverables?
Documents and proof to request
- Full quotation with component brands, model numbers, options, accessories, warranty terms, and exclusions.
- Factory license, export company name, bank account identity, and invoice identity so the contracting party is clear.
- Machine photos or videos that show the quoted model, control cabinet, controller screen, spindle or laser source, and nameplate.
- Sample acceptance report, packing photos, previous export packaging examples, and manual/documentation samples.
Red flags that deserve follow-up
- The supplier sells many unrelated machines but cannot explain which workshop builds your model.
- The quote uses vague component language, such as famous brand, imported parts, or high precision, without written specifics.
- The salesperson pushes deposit quickly but avoids acceptance tests, spare parts, installation, or after-sales questions.
- The company name on the quote, website, business license, and bank details does not match or is not explained.
