Son Ha Int'l Investment & Development

Son Ha Int'l Investment & Development is based in Viet Nam and currently lists 26 active products. The catalogue covers mineral and chemical commodities such as limestone, calcium carbonate, kaolin, marble slabs, dolomite, barite and related ores. Products are classified under HS chapters 25 (mineral ores) and 28 (chemical products), with specific codes 2836.50 for calcium carbonate powders and 2507.00 for ceramic grade kaolin. The supplier’s portfolio includes both raw stone forms (e.g., white marble slab stone, chipping stone) and processed powders (e.g., precipitated calcium carbonate, limestone granules). Export listings indicate applications in construction, plastics, feed, paper, glass making and oil drilling. The trust tier is recorded as "harbor", indicating a mid‑level verification status in the sourcing platform.

The product list comprises white marble slab stone for paving, various limestone granular grades for poultry and fish feed, limestone powder for water treatment, and limestone powder 80 mesh for feed. Calcium carbonate offerings include ground calcium carbonate for plastic, high‑purity precipitated calcium carbonate (>98.5 %) for HDPE pipe and paper, and a toile‑cleaner grade at 98.5 % purity, all under HS code 2836.50. Kaolin products are presented as ceramic grade kaolin and glaze/body ceramic kaolin, each meeting typical silica (SiO₂ > 48 %) and alumina (Al₂O₃ > 37 %) thresholds and classified under HS code 2507.00. Additional minerals such as dolomite lump for floating glass (HS 2518.20) and barite powder for oil‑field drilling mud are also listed. In the broader industry, limestone for feed is commonly sized 2‑4 mm with calcium carbonate purity above 95 %, while marble slabs for terrazzo are supplied in 2‑3 m panels with surface flatness tolerance of 0.5 mm. Calcium carbonate powders for plastics typically target particle sizes of 5‑30 µm and bulk densities around 1.5 t/m³, and kaolin used in ceramics is graded by plasticity index and fired whiteness (ICUMSA 10‑20).
