About CNK International Corporation - Medical Sterilizers Supplier in South Korea (Republic Of Korea)

CNK International Corporation is based in Incheon, South Korea (Republic Of Korea) and currently lists 17 active products across metal ingots, chemicals, agricultural and consumer goods. The catalogue spans primary metal ingots such as zinc (HS 7901.11), aluminum (HS 7601.11), lead (HS 7801.10) and copper cathode (HS 7403.11), as well as copper wire scrap (HS 7404.00) and hydrogen peroxide (HS 2847.00). Additional items include cosmetics, corn, mineral water, sanitary pads (HS 9619.00), palm oil, baby diapers, various teas, disposable kitchen towels and fruit puree. The supplier is classified in the “organic” tier and carries a “harbor” trust tier within the platform. The product mix reflects typical export categories from South Korea, ranging from high‑purity metal commodities to consumer health and food items.

The metal ingots are described with minimum purity levels: SHG zinc at 99.995 % purity, primary aluminum Grade A7 at 99.7 % Al, refined lead between 99.97 % and 99.99 % purity, and electrolytic copper cathode meeting LME Grade A at 99.99 % Cu. Copper wire scrap is specified as Millberry grade with 99.9 % Cu content. The chemical offering includes hydrogen peroxide concentrations of 35 % to 70 % and a baby diaper composition that combines fluff pulp, superabsorbent polymer, non‑woven PP/PE fabric and elastic waistbands. Agricultural products such as yellow corn and palm oil are listed without HS codes, while food‑grade items include fruit puree and health teas. Consumer hygiene items cover sanitary pads and disposable kitchen towels, each typical of fast‑moving consumer goods exports.

Product Range and Specialties of CNK International Corporation

The metal portfolio comprises zinc ingots (HS 7901.11) meeting Special High Grade specifications of at least 99.995 % Zn, aluminum ingots (HS 7601.11) conforming to Grade A7 standards of 99.7 % Al, lead ingots (HS 7801.10) within the 99.97‑99.99 % purity range, and copper cathodes (HS 7403.11) that satisfy LME Grade A requirements of 99.99 % Cu. These grades are aligned with ASTM B507 for zinc, ASTM B221 for aluminum, and ISO 9001 quality management practices commonly required for bulk metal exports, and they are typically packed in 25 kg or 30 kg ingot molds for container loading.

Chemical and consumer product lines follow industry norms: hydrogen peroxide (HS 2847.00) is offered at 35 %‑70 % concentrations and is usually shipped in 200 L HDPE drums with UN 1993 classification; cosmetics and health teas are subject to ISO 22716 manufacturing standards and may require HACCP or GMP documentation for food‑grade items. Baby diapers, sanitary pads and disposable kitchen towels are produced with non‑woven PP/PE fabrics and SAP components, and exporters normally provide ISO 9001 certificates, product safety test reports and compliance statements for REACH or CPSC where applicable.

Trade and Export Information - CNK International Corporation

South Korea’s metal export sector primarily serves buyers in China, Japan, the United States and the European Union, with zinc, aluminum, lead and copper ingots commonly cleared under HS chapters 79, 76, 78 and 74 respectively. Importers typically request assay certificates, mill test reports and a Certificate of Origin, and shipments are frequently arranged on FOB Incheon Port or CIF to the destination port using 20‑ft or 40‑ft containers.

For chemical products such as hydrogen peroxide, exporters must provide a Material Safety Data Sheet (MSDS), a UN number declaration and compliance with the Globally Harmonized System (GHS). Food‑related items like corn, palm oil, fruit puree and health teas are subject to sanitary certificates, pesticide residue testing and, where required, Halal or Kosher certifications. Standard logistics include ocean freight, with Incoterms FOB or CIF, and documentation typically comprises a commercial invoice, packing list, certificate of origin and any required phytosanitary certificates.

Sourcing from CNK International Corporation - Buyer Guidance

Buyers should request independent assay reports or mill test certificates that verify the stated purity levels for each metal ingot, as well as a full material safety data sheet for hydrogen peroxide before confirming a purchase. For consumer and food products, request compliance test reports for pesticide residues, microbiological limits, absorbency (for diapers) and any relevant ISO or REACH certifications to ensure regulatory conformity in the target market.

When evaluating packaging, confirm that metal ingots will be delivered in standard 25 kg or 30 kg molds secured in wooden crates suitable for container loading, and that chemical drums meet UN 1993 specifications. Verify that all shipments will be accompanied by the required export documents - commercial invoice, packing list, certificate of origin and, where applicable, sanitary or phytosanitary certificates - to avoid customs delays.

What metal purity documentation does CNK provide for its zinc and aluminum ingots?

Buyers should request an independent assay report or mill test certificate that confirms the minimum 99.995 % Zn purity for the SHG zinc ingot and the 99.7 % Al content for the Grade A7 aluminum ingot, both of which are standard in the metal trade.

Which HS codes apply to the copper products listed by CNK?

The copper cathode is listed under HS 7403.11, while copper wire scrap falls under HS 7404.00; both codes are used internationally for electrolytic copper products and are required on customs documentation.

How are the hydrogen peroxide concentrations packaged for export?

CNK offers hydrogen peroxide at 35 %, 50 %, 60 % and 70 % concentrations, typically packed in 200 L HDPE drums complying with UN 1993 classification, and a Material Safety Data Sheet should accompany each shipment.

What certifications are commonly required for the baby diaper product?

Importers usually request ISO 9001 quality management certification, a test report for absorbency and flammability, and compliance with EU REACH or US CPSC regulations; buyers should ask CNK to provide these documents before order confirmation.

Are there standard packaging sizes for the metal ingots?

Zinc, aluminum, lead and copper ingots are generally shipped in 25 kg or 30 kg standard ingot molds, packed in wooden crates or bulk containers suitable for 20‑ft or 40‑ft ocean containers, enabling efficient loading and handling.

What documentation is needed for the food‑grade items such as corn and fruit puree?

Buyers should obtain a Certificate of Origin, a sanitary certificate, and a laboratory analysis report confirming pesticide residue limits and microbiological standards, which are typical requirements for agricultural exports from South Korea.

Which markets commonly import the listed metal and chemical products from South Korea?

Major import destinations include China, Japan, the United States and European Union members; these regions frequently source high‑purity metal ingots and industrial chemicals under CIF or FOB terms, supported by standard customs paperwork.

How should a buyer verify the quality of the copper wire scrap?

Request a Millberry grade test report that specifies the 99.9 % Cu content, along with a visual inspection report for surface contaminants; these documents are standard for assessing scrap metal quality before shipment.
