Trade & Delivery
Commercial Terms, Made Explicit
Payment, lead time, warranty, shipping and after-sales at a glance — the terms international buyers need before a purchase decision. Everything below is our standard practice; the exact numbers for your order are always confirmed in writing on your Proforma Invoice.
Quotation & Pricing
- All quotations are issued in USD on a Proforma Invoice (PI) and remain valid for 30 days unless stated otherwise.
- You choose the price basis: EXW Changsha, FOB (Shanghai or Shenzhen), or CIF — we state it clearly on every PI.
- The quotation identifies the instrument, accessories, available verification documents and export packing included in your order.
- Price, scope and response timing are confirmed for the individual inquiry rather than assumed from this page.
Payment Terms
- Typical schedule: 30% deposit with the signed PI, 70% balance before shipment (copy of packing list & shipping documents provided).
- Accepted methods: T/T bank transfer (standard), irrevocable L/C at sight (for larger orders), or negotiable terms for repeat/partner buyers.
- Payment terms can be adjusted per order size, country and credit history — discuss with your sales engineer.
Lead Time
- Production lead time depends on model, configuration and order volume; request the current schedule.
- In-stock status and any expedited option must be confirmed in writing before payment.
- The confirmed lead time is always stated on your PI and shipping schedule.
Shipping & Export Documents
- Sea or air freight, arranged by us or your forwarder — FOB/CIF terms include our coordination of the exporting leg.
- Export packing and inspection requirements are stated for the defined shipment and destination.
- Destination-country voltage handled at the factory: 110 V / 220 V, 50/60 Hz — tell us your plug standard.
- Documents supplied: Commercial Invoice, Packing List, Certificate of Origin, Bill of Lading/Airway Bill, and (on request) Certificate of Origin form, health/fumigation certificates.
Warranty
- Warranty duration, start date, covered parts and exclusions are stated in the quotation and contract.
- Any extended warranty option must be confirmed for the ordered model.
- Consumables (crucibles, oxygen bombs, reagents, seals) and damage from misuse are excluded — your sales engineer will list covered items in the PI.
Installation & Training
- Remote commissioning and operator training scope are confirmed for the ordered configuration.
- On-site installation & operator training is available as an option (travel cost plus per-day fee) — quote upon request.
- English operation manual, quick-start guide and video tutorials ship with every instrument.
Spare Parts & After-Sales
- Request the model-specific spare-parts list, availability period and response process before ordering.
- Remote diagnosis, replacement and shipping responsibilities are defined in the agreed support scope.
- Annual calibration & preventive-maintenance service plans available for commercial labs that need audit-grade traceability.
OEM / ODM & Customization
- Custom sample counts, voltage/plug standards, chamber configurations, color/branding and report formats are available for distributors and OEM partners.
- Tell us your target market standards (ISO/ASTM/GB or local equivalents) — methods are verified with certified reference materials before shipment.
Which terms apply to my order?
This page describes our standard commercial framework. The binding conditions for your specific order — exact price, delivery time, warranty scope and payment schedule — are always stated in your formal quotation (Proforma Invoice) and prevail over this page. Send your model, sample type, target standard, destination and evidence requirements so we can confirm the scope in writing.
