Importing GGBFS from China is straightforward when the specification, documents and shipping basis are fixed before quotation.
Miningsun supplies export-ready ground granulated blast furnace slag from China for international buyers who need stable quality, clear documentation and responsive quotation support. This guide explains what procurement teams usually ask before placing a trial order or full-container order.
Start with the specification, not only the price
International buyers should define the grade and application before asking for the lowest price. For GGBFS, the relevant specification usually includes S75, S95 and S105, the required standard (ASTM C989, EN 15167 and GB/T 18046) and the target application: ready-mix concrete, precast concrete, mass concrete, marine concrete and low-carbon cement blending.
A clear specification helps the supplier confirm available stock, test reports and suitable packaging before preparing the commercial offer.
Confirm MOQ, packaging and loading plan
MOQ depends on bulk density, packaging and the economics of container loading. Trial samples are useful for lab approval, but full-container shipments usually provide the best landed cost.
- Available packaging: 1 MT or 1.25 MT jumbo bags, bulk vessel or containerized bulk
- Common loading ports: Tianjin, Qingdao, Shanghai or Lianyungang
- Shipping terms: FOB, CFR or CIF
- Documents: TDS, COA, mill test certificate and SGS/BV inspection when requested
Check supplier reliability before payment
Ask for recent COA samples, packaging photos, loading photos and references from similar export markets. A good exporter should explain realistic lead time, testing limitations and whether the goods can be inspected by SGS, BV or another third party before shipment.
For repeat orders, lock a repeatable specification and keep batch documents for each shipment. This makes quality comparison easier when shipments arrive months apart.

GGBFS import checklist for cement and concrete buyers
Ground granulated blast furnace slag is usually purchased for cement blending, ready-mix concrete, precast products and durability improvement. Before comparing suppliers, confirm the target grade, fineness, activity index, moisture and packing method. GGBFS is sensitive to handling and storage, so the buying discussion should cover both laboratory values and the practical loading plan.
Specification points to confirm before quotation
| Item | What to ask the supplier | Why it matters |
|---|---|---|
| Grade and fineness | S95, S105 or buyer-specific activity target, plus Blaine/fineness data | Grade and fineness influence strength development and cement replacement rate. |
| Chemical values | CaO, SiO2, MgO, SO3, chloride and loss on ignition where required | These values help buyers compare compatibility with local cement standards. |
| Moisture and packing | Moisture limit, jumbo bags, bulk option and container loading weight | Moisture and packing affect storage quality, unloading speed and landed cost. |
| Documents | COA, TDS, MSDS, packing photos and shipment documents | Complete documents help importers pass internal approval and customs review. |
MOQ, payment and shipment notes
A common commercial path is to confirm documents first, then arrange a sample or trial shipment, then move to repeat container orders after mix-design approval. For CIF offers, provide destination port, packing requirement, expected order quantity and whether the shipment is urgent. If the product will be used in ready-mix or precast concrete, also share the target replacement percentage and any required test age such as 7-day or 28-day strength.
