Frequently Asked Questions for New Inquirers
Clear, upfront answers on commercial conditions, global shipping lead times, technical inspections, and contract terms.
What exact information is required for an accurate quotation?
To issue a firm, itemized BOM pricing report within 2 hours, we need: 1) Required steam or heat output (e.g. 10 Ton/hr or MW), 2) Design operating pressure (e.g. 1.25 MPa / 180 PSI), 3) Fuel type and calorific value (e.g. Light diesel, heavy bunker oil, or natural gas), and 4) Port of destination. If you have existing boiler room blueprints or replacement sketches, uploading them allows our team to check flue clearance and piping connections immediately.
How long does international sea freight and production lead time take?
Standard WNS horizontal oil-fired boilers (1 to 20 Ton/h) have a standard production cycle of 25 to 35 business days. For shipping: Southeast Asian ports typically take 7-12 days; Middle East ports take 18-25 days; Latin America and European main ports take 28-38 days. Expedited skid-mounted boilers are kept in semi-assembled stock for urgent plant replacement requirements.
Can Dabonn accommodate SGS or Bureau Veritas third-party inspections?
Yes, absolutely. Dabonn regularly coordinates with SGS, Bureau Veritas (BV), TÜV, and Lloyd's Register. Third-party inspectors have full access to our facility to verify raw material mill certificates, witness radiographic weld tests (RT), verify hydraulic pressure testing at 1.5x design pressure, and seal container doors prior to departure.
What payment and contractual terms are supported for international orders?
We accommodate standard international industrial trade financing: 100% Irrevocable Documentary Letter of Credit (L/C at sight) issued by prime international banks, or Telegraphic Transfer (T/T) structured as 30% advance deposit with 70% balance payable against Bill of Lading (B/L) copy and third-party inspection sign-off.
