About Nanjing Bloom Stone - Stones & Slates Supplier in China

Nanjing Bloom Stone is registered in China and currently lists five active products across three categories: Stones & Slates, Glass Beads, and Granite & Marble Products. The catalogue includes washed black‑grey river rock pebbles, polished black pebble stones, high‑polished black pebble stones, fire‑glass pebble beads used as vase fillers, and a glass marble ball marketed as a toy. Each item falls within the natural‑stone or decorative‑glass HS code families commonly used for export, such as HS 2515 for natural stone and HS 7018 for glass beads. The supplier’s product count and category spread indicate a focus on decorative landscaping and interior‑design applications.

Product Range and Specialties of Nanjing Bloom Stone

The stone items - river rock, polished pebble, and high‑polished pebble - are typical of the processed‑stone market where sizes range from 5 mm to 30 mm and surface finishes are classified by polish grade (e.g., 2‑star to 5‑star). Buyers often specify ICUMSA‑like clarity for color uniformity, even though the industry does not use a formal numeric grade for decorative stone. The fire‑glass beads belong to the glass‑decorative segment; standard diameters are 3 mm, 5 mm or 8 mm, with a typical break‑strength of 1.5 MPa and a color consistency measured by spectrophotometer. The glass marble ball is a toy‑grade glass sphere, usually produced to ASTM C1048 specifications for impact resistance and a surface smoothness of less than 0.2 mm Ra. These specifications align with the broader market expectations for Chinese exporters of decorative stone and glass products.

Trade and Export Information - Nanjing Bloom Stone

China remains one of the largest exporters of natural stone and decorative glass, supplying the EU, North America, the Middle East and Southeast Asian markets. HS chapter 25 (natural stone) and chapter 70 (glass) dominate customs filings, with most shipments using 20‑ft or 40‑ft containers packed in woven polypropylene bags or bulk cardboard boxes. Importers typically request CE marking, REACH compliance and ISO 9001 quality‑management certification for these categories, although the supplier’s own certifications are not listed. Freight terms frequently involve FOB Shanghai or Ningbo, with buyers arranging CIF to their destination ports. Seasonal demand peaks in the spring construction cycle for landscaping stone and in the holiday season for decorative glass items.

Sourcing from Nanjing Bloom Stone - Buyer Guidance

When sourcing from Nanjing Bloom Stone, request detailed product datasheets that list size distribution (e.g., 5‑15 mm, 15‑30 mm), weight per unit, and surface‑finish grade. Obtain a recent third‑party test report for color consistency, break‑strength (for glass beads) and surface hardness (for polished stone). Ask for material‑safety data sheets and confirm compliance with REACH and any ISO standards the buyer’s market requires. Verify packaging dimensions and load‑bearing capacity of bags or boxes to ensure safe container loading, and request a sample batch before confirming large orders.
