Review the published reference grade.
Use these values to frame your enquiry. The specification and analysis for the offered material must be confirmed with the team.
| Parameter | Published reference |
|---|---|
| CaO / MgO content | CaO 50–56%; MgO 28–33%. |
| SiO₂ / Fe₂O₃ | SiO₂ ≤2.4%; Fe₂O₃ ≤1.5%. |
| Loss on ignition | LOI ≤7%. |
| Particle size | 10–60 mm or 20–60 mm, with a published 90% size fraction. Agree the exact grading and fines limits. |

Tell us where the material will be used.
For steelmaking, identify the furnace or refining stage and the CaO/MgO balance your process team requires. For refractory enquiries, state whether the process requires a different calcination or density profile.
See application enquiry checklistsPlan for the receiving site.
Hong Ha lists 1,250 kg laminated bags, with or without an inner liner, and a referenced load of 25 MT per 20-foot container. The published starting order is one container. Confirm liner, bag strength, unloading method and route payload before shipment.
Include your destination port or receiving location, requested FOB / CFR / CIF term with its named port, and target shipment window. Shipment availability and commercial terms are agreed in the quotation.
Compare the same basis.
Confirm the distinction between calcined dolomite, dead-burned material and unburnt dolomite. A chemical range alone does not establish suitability for a refractory product or another end use.
Analysis
Request the relevant COA, the measured parameters, test methods and sample or batch identification.
Sample or trial
Share the sample quantity, evaluation method and approval criteria. Availability and terms need confirmation.
Handling documents
Ask for the current SDS and discuss the packing, storage and unloading requirements with your site team.
