Pure mineral stone from Nghe An
Over 20 years of mining and processing — we build every relationship one on-time container at a time.
Owning every step of the chain.
Long Anh directly mines and processes pristine white limestone from 5 owned quarries in Quy Hop, Nghe An — whiteness above 98%, CaCO₃ above 98.5%.
Five plants on 12 ha run 6 dry-grinding lines and 2 stearic-acid coating lines built to European spec — total capacity above 350,000 tons/year.
Every ton of stone powder is a promise — quality, schedule, and a long-term partnership.
20 years — one continuous vein
Founded
Founded in Quy Hop, Nghe An with our first white limestone quarry — the base of today’s closed mining-to-processing chain.
First plant
Installed our first dry-grinding line at 80,000 tons/year — moving Long Anh from raw extraction into deep processing.
Coating line
Commissioned a European-spec stearic-acid coating line — opening the door to PVC, PE and PP compound markets.
ISO 9001
Certified ISO 9001:2015 for quality management; the first containers shipped to Korea and Japan.
Expansion
Opened the 1.6 × 2.4 m Slab workshop; system-wide capacity reached 350,000 t/year across 12 export countries.
Three things we never compromise on
Pure raw material
Stone comes only from our 5 owned quarries in Quy Hop — whiteness above 98%, CaCO₃ above 98.5%. Quality is controlled from extraction, never from spot-market feedstock.
Precision technology
European-spec grinding and stearic-acid coating lines hold D50 particle size within 4–20 µm. Every batch passes four QC criteria before leaving the plant.
On-time delivery
FOB via Cua Lo and Hai Phong ports, every batch with full COA and MSDS. Packaging flexes by market — a confirmed schedule is a kept schedule.
The plants. By the numbers.
Five plants on 12 ha in Quy Hop run 6 dry-grinding and 2 stearic-coating lines — a steady 350,000 tons/year with order-by-order flexibility for B2B customers.
