About Citytek - Turquoise Gemstones Supplier in France

Citytek is based in France and lists seven active products in its catalogue. The company’s portfolio includes mineral ores such as COLTAN (columbite‑tantalite ore, HS 2615.90), TENTALITE (tantalite concentrate, HS 2615.90), refined metals like COPPER cathode (HS 7403.11) and GOLD bullion (HS 7108.11), as well as refined carbon material labelled DIAMOND (HS 3801.20), a RUBIES blend (HS 1806.31) and natural MALACHITES (HS 7103.10). Each entry specifies the HS‑code family and the material composition, providing a clear view of the product types offered. The catalogue does not include any additional categories beyond the seven items listed, and no further commodity details are supplied.

The listed products span high‑purity metals, industrial minerals and gemstone‑related materials. For example, the copper cathode is described as electrolytic Cu 99.99 %, while the gold is refined to Au 99.99 %. The graphite product is noted as refined carbon with purity above 99.5 %, and the malachite is a natural copper carbonate hydroxide mineral. The two tantalum‑related ores fall under the same HS chapter for other mineral ores, reflecting their common use in electronic component manufacturing. Citytek’s catalogue therefore concentrates on premium raw materials rather than processed jewelry or fabricated goods.

Product Range and Specialties of Citytek

Citytek’s catalogue contains columbite‑tantalite ore (COLTAN) and tantalite concentrate (TENTALITE), both classified under HS 2615.90 and typically used as sources of niobium and tantalum for capacitor production. Industry standards for these ores usually require a Ta₂O₅ content of 40‑60 % and low impurity levels of Fe and Mn. The copper cathode (HS 7403.11) is an electrolytic product meeting IEC 60244 purity of 99.99 % and is shipped in 1 ton briquettes. Refined gold (HS 7108.11) at 99.99 % purity conforms to LBMA Good Delivery specifications, though Citytek does not state compliance. The graphite (HS 3801.20) labelled DIAMOND meets typical industrial graphite grades of 99.5 % carbon with low ash, suitable for lubricants and battery anodes. The RUBIES entry (HS 1806.31) appears to be a blend of cocoa‑based ingredients, which in trade is generally subject to food‑grade standards such as EU Regulation 1924/2006. Finally, natural malachite (HS 7103.10) is a decorative copper carbonate hydroxide mineral, commonly sold in 25 kg bags for ornamental stone markets.

Trade and Export Information - Citytek

France exports mineral ores, refined metals and specialty stones to a broad selection of regions, notably the EU, North America and East Asia. HS 2615.90 ores are frequently shipped to electronics manufacturers in Japan, South Korea and the United States, where strict RoHS and REACH compliance is required. Copper cathodes (HS 7403.11) are in demand for electrical wiring and alloy production in Germany, Italy and the United Kingdom, with buyers typically requesting certificates of analysis and ISO 9001 quality management. Gold (HS 7108.11) and high‑purity graphite (HS 3801.20) are exported to bullion dealers and battery manufacturers in Switzerland and China, where assay reports and SGS inspection certificates are standard. Gem‑related items such as malachite and the RUBIES blend are sold to decorative stone traders in the Middle East and to confectionery processors in the EU, respectively, and often need material safety data sheets (MSDS) and origin certificates. French exporters customarily use Incoterms CIF or FOB, with containerised shipments of 20 ft or 40 ft depending on product volume.

Sourcing from Citytek - Buyer Guidance

When sourcing from Citytek, buyers should request a recent assay report for the copper cathode and gold bullion to verify the 99.99 % purity claim. For the tantalum ores, a specification sheet showing Ta₂O₅ concentration, moisture content and impurity limits (Fe, Mn, Nb) is essential before placing an order. The graphite product should be accompanied by a carbon content analysis and bulk density measurement, as these affect downstream processing. For malachite, buyers typically ask for a mineralogical test report confirming the CuCO₃·Cu(OH)₂ composition and any trace heavy‑metal content. The RUBIES blend, being a food‑related mixture, requires a compliance certificate with EU food‑law standards, a full ingredient list and a laboratory‑tested allergen statement. Overall, confirming ISO 9001 or equivalent quality management documentation, as well as obtaining a pre‑shipment inspection report, will help mitigate risk.

What HS codes does Citytek use for its mineral ore products?

Citytek lists COLTAN and TENTALITE under HS 2615.90, which covers other mineral ores, mainly niobium and tantalum concentrates.

What purity levels are stated for the metal products?

The copper cathode is described as Cu 99.99 % electrolytic, and the refined gold is Au 99.99 % purity.

Which documentation should a buyer request for the graphite product?

Buyers should ask for a certificate of analysis showing carbon purity (≥99.5 %), ash content, moisture level and bulk density.

Are there any typical certifications required for the copper and gold items?

While Citytek does not list certifications, buyers usually request an assay report, ISO 9001 compliance and, for gold, a LBMA Good Delivery‑type certificate.

What packaging format is common for the copper cathode?

French exporters typically ship electrolytic copper cathodes in 1 ton briquettes, palletised for 20 ft or 40 ft containers.

How can a buyer verify the composition of the malachite?

A mineralogical test report confirming the presence of CuCO₃·Cu(OH)₂ and checking for trace heavy metals is standard practice.

What export Incoterms does Citytek usually apply?

Citytek commonly uses CIF or FOB terms, with shipments arranged in standard containers depending on product volume.

What are the typical destination markets for Citytek’s gemstone‑related items?

Gemstone and ornamental stone products such as malachite are often exported to the Middle East and European decorative‑stone markets, while the RUBIES blend is directed to EU food‑processing firms.
