Pure mineral stone
from the heart of Nghe An
Long Anh manufactures coated and uncoated CaCO₃ powder, slab stone, cut-to-size tile and decorative stone — serving plastics, paint, paper, construction, and global export markets.
Five core product lines
Tuned to each end use — from ultra-fine plastics filler to large decorative slab.
Uncoated CaCO₃ powder
Dry-ground GCC with high whiteness in multiple particle sizes — for paint, putty, adhesives, animal-feed additives and masterbatch.
Stearic-acid coated CaCO₃
Stearic-acid coating improves dispersion and reduces moisture pickup — ideal for PVC, PE, PP compounds and premium masterbatch.
Slab stone
Polished natural-vein slab — for premium countertops, interior wall cladding and showroom installations.
From quarry to container.
Originating from the white limestone region of Quy Hop, Nghe An, Long Anh owns high-grade quarries with whiteness exceeding 98% and CaCO₃ content above 98.5%.
Production capacity
A five-plant complex on 12 ha in Quy Hop, Nghe An, running 6 dry-grinding lines and 2 stearic-acid coating lines built to European spec. Total capacity exceeds 350,000 tons/year, produced steadily against each partner’s delivery schedule.
Raw material
Long Anh directly operates 5 quarries of pristine white limestone in Quy Hop — one of Vietnam’s finest raw-material regions. Whiteness above 98% and CaCO₃ above 98.5%, with quality controlled from extraction and stone sorting onward.
Infrastructure
Raw stone is staged by grade zone; finished goods are palletized and lot-coded by product. Loaders and trucks run throughout the day, on convenient routes to Cua Lo and Hai Phong ports — keeping every export schedule in our control.
Quality control
In-house QC tests every batch on four criteria: whiteness, CaCO₃ content, moisture and D50 particle size (4–20 µm). Every batch ships with COA and MSDS under ISO 9001:2015 — with independent SGS verification on request.
Packaging
PP bags of 25 kg and 50 kg, jumbo bags of 250/500/1000 kg, or bulk containers to order — private-label printing available. Container cargo is moisture-protected and sealed before leaving the plant.
Built to international standards.
Each batch is QC-controlled to ISO 9001 and ships with COA and MSDS — meeting the toughest requirements from Korea, Japan, India and the Middle East.
