About Hoang Gia Mineral Group - Agriculture Supplier in Viet Nam

Vietnam-based Hoang Gia Mineral Group lists twelve distinct calcium carbonate powder products. The catalogue includes generic Calcium Carbonate Powder and ten variants identified by KSHG grades ranging from 08 to 75, covering low to high particle size specifications. All items fall under the agriculture category in the supplier’s classification. The product titles reference KSHG grain size grades commonly used in the industry to denote median particle diameter in micrometres. No additional product attributes such as purity or packaging are detailed in the supplied data.

The supplier’s active product count of twelve reflects a focus on calcium carbonate powders of differing particle size distributions. The KSHG designations (08, 10, 12, 15, 17, 20, 25, 30, 45, 60, 75) correspond to typical industry grades used for applications such as paper coating, polymer filler, and agricultural lime. While the catalogue does not specify HS codes, calcium carbonate powders are generally classified under HS chapter 25. The supplier’s trust tier is listed as “harbor,” indicating a moderate level of verification in the platform’s system.

Product Range and Specialties of Hoang Gia Mineral Group

Hoang Gia Mineral Group’s catalogue is limited to calcium carbonate powder products differentiated by KSHG grain size grades. In the broader market, calcium carbonate powders are offered in grades such as industrial grade (purity 95‑98 %), food‑grade (purity ≥ 99 % and meeting FDA/EFSA specifications), and pharmaceutical grade (purity ≥ 99.5 %). Typical particle size specifications are expressed in micrometres, with KSHG 08 representing fine powders (~8 µm) and KSHG 75 representing coarse powders (~75 µm). Buyers often request data on bulk density (0.6‑0.8 g cm⁻³), moisture content (< 0.5 %) and loss on ignition (< 0.2 %).

Standard packaging for bulk calcium carbonate includes 25 kg paper bags, 1‑ton polypropylene bulk bags, and full‑container loads in 20‑ft or 40‑ft containers. For industrial applications the material may also be supplied in bulk silos or truck‑load shipments. The KSHG grade determines suitability: fine grades are preferred for paper and paint fillers, while coarse grades are common in agricultural lime and construction fillers.

Trade and Export Information - Hoang Gia Mineral Group

Vietnam is a growing exporter of calcium carbonate, primarily sourced from limestone deposits in the northern and central regions. Export shipments are typically routed to Southeast Asian markets, China, the European Union and North America, where the material is used in paper manufacturing, plastics, paints and agricultural amendments. The HS code 2520.10 (calcium carbonate, other) is the usual classification for bulk powder, and customs inspections often require a certificate of analysis and a certificate of origin.

Logistics from Vietnam frequently use FOB Ho Chi Minh City or Da Nang ports, with container loads ranging from 20 ft (≈ 20 ton) to 40 ft (≈ 35 ton) depending on packaging. Buyers usually request compliance with ISO 9001 quality management and, for food‑grade applications, REACH registration or FDA/EFSA conformity. Importing countries may require a phytosanitary certificate when the product is intended for agricultural use.

Sourcing from Hoang Gia Mineral Group - Buyer Guidance

When sourcing calcium carbonate powder from Hoang Gia Mineral Group, buyers should request a recent certificate of analysis that details purity, particle size distribution (KSHG grade), moisture and loss on ignition. Samples of the specific KSHG grade can be requested to verify performance in the intended application, such as paper coating or polymer compounding.

In addition, verify that the supplier can provide the necessary regulatory documents, including a declaration of conformity to ISO 9001 and, if required, REACH or FDA compliance certificates. Clarify packaging options, minimum order quantities (often 1 ton for bulk grades) and lead times, which typically range from 30 to 45 days after order confirmation.

What does the KSHG designation indicate for calcium carbonate powder?

KSHG refers to the Krumbein‑Schoenfeld grain size grading system, where the number denotes the approximate median particle diameter in micrometres. For example, KSHG‑08 corresponds to a mean size of about 8 µm, while KSHG‑75 indicates a mean size near 75 µm.

Which certifications should I request for calcium carbonate intended for food applications?

For food‑grade calcium carbonate, buyers typically ask for a certificate of analysis, FDA or EFSA compliance documentation, and a REACH registration statement. An ISO 22000 or ISO 9001 quality‑management certificate is also commonly required.

What are the common packaging options for bulk calcium carbonate powder?

Standard bulk packaging includes 25 kg paper bags, 1‑ton polypropylene bulk bags, and full‑container loads (20‑ft or 40‑ft) sealed in moisture‑resistant liners. Larger orders may be shipped in silo or truck‑load bulk containers.

What is the typical lead time for an order from Vietnam?

Lead times generally range from 30 to 45 days after order confirmation, depending on product grade, packaging selection and shipping schedule. Expedited production may be arranged for an additional fee.

Which HS code is normally used for calcium carbonate powder in customs paperwork?

Customs authorities usually classify calcium carbonate powder under HS code 2520.10, which covers calcium carbonate in powder form not elsewhere specified.

What documentation is needed to import calcium carbonate powder into the European Union?

Importers should provide a certificate of origin, a certificate of analysis, and evidence of REACH compliance. Depending on the end‑use, a safety data sheet (SDS) and, for agricultural applications, a phytosanitary certificate may also be required.
