About Liaoning EO Technology Co., Ltd. - Copper Supplier in China

Liaoning EO Technology Co., Ltd. is based in China and currently lists 15 active products across its catalogue. The company’s primary focus is on copper materials, including pure copper rod, foil, busbar, sheet and tube, which fall under HS Chapter 74 (e.g., 7407.11, 7407.12, 7409.11, 7409.19). These copper items are described as electrolytic refined or tough‑pitch grades with minimum purities of 99.9 % and, for the foil, 99.99 % copper. In addition to copper, the catalogue contains video cable adapters classified under HS 8536.90, and several IP‑rated security cameras without HS codes listed. Other entries include PTFE‑based mechanical seal plates and a UV wood paint, expanding the product mix beyond metals.

The copper rod is offered as a standard electrolytic refined grade (UNS C10100/C11000) suitable for electrical conductors and heat‑exchange applications. Copper foil is supplied with 99.99 % purity, a common specification for printed circuit board (PCB) laminates and battery tab applications. Busbars and sheets are identified as ETP copper, a material frequently used in power distribution panels where low resistivity is critical. The copper tube, also 99.99 % pure, matches typical dimensions for hydraulic and refrigeration lines. Security cameras listed include bullet, dome, PTZ and HD variants, which are typical IP‑based surveillance devices used in commercial and industrial settings. The PTFE plates and boards are standard engineering plastics employed in high‑temperature sealing and electrical insulation.

Product Range and Specialties of Liaoning EO Technology Co., Ltd.

The catalogue features pure copper rod, foil, busbar, sheet and tube, each conforming to electrolytic refined or tough‑pitch grades that are standard in the electrical and industrial sectors. Typical copper rod diameters range from 6 mm to 50 mm with tolerance ±0.2 mm, while foil thicknesses are commonly 0.01 mm to 0.2 mm and measured in microns. Busbars are usually supplied in widths of 50 mm to 200 mm and thicknesses of 2 mm to 10 mm, complying with IEC 60228 class 1 conductivity requirements. Copper sheets often appear in thicknesses from 0.2 mm to 5 mm and are rolled to dimensions up to 2000 mm × 2000 mm. Copper tube specifications typically include nominal diameters from 10 mm to 100 mm with wall thicknesses adhering to ASTM B88 standards. The composite video cable adapter combines phosphor‑bronze contacts with gold‑plated connectors, a material pairing that meets IEC 60757 for contact resistance. Security cameras such as bullet, dome, PTZ and HD models generally support IP 66 or IP 67 ingress protection and resolutions from 2 MP to 4 MP, aligning with ONVIF profile S standards. PTFE plates and boards are engineered for continuous service up to 260 °C, with typical board thicknesses of 1 mm to 10 mm, while UV wood paint is formulated for exterior wood protection with UV‑stabilizers.

Trade and Export Information - Liaoning EO Technology Co., Ltd.

China is a leading exporter of electrolytic refined copper products, and the HS codes 7407 and 7409 cover a broad selection of copper shapes used in power transmission, electronics and automotive sectors. Major import markets include the United States, the European Union, South Korea and Japan, where buyers often require ISO 9001 quality management certification and compliance with REACH and RoHS for trace metal content. Copper shipments are typically packed in wooden crates or bulk bags, with moisture content below 0.02 % to prevent oxidation, and are shipped in 20‑ft or 40‑ft containers under FOB or CIF terms. Inspection agencies such as SGS or Bureau Veritas frequently conduct pre‑shipment audits to verify purity certificates and dimensional tolerances.

IP‑based security cameras from China are commonly exported to Africa, the Middle East and Southeast Asian markets, where robust enclosure ratings (IP 66/67) and ONVIF compatibility are standard requirements. The video cable adapters fall under HS 8536.90, a category for other electrical apparatus, and buyers usually request CE marking and UL listing for the connectors. PTFE plates and boards are used in chemical processing and semiconductor equipment; exporters often provide material safety data sheets (MSDS) and certify compliance with ASTM 631 and ISO 10993 for biocompatibility when applicable. Typical packaging includes vacuum‑sealed poly‑bags inside sturdy cartons, and shipments are arranged in containers with temperature monitoring for the PTFE items.

Sourcing from Liaoning EO Technology Co., Ltd. - Buyer Guidance

When sourcing copper rod, foil, busbar, sheet or tube, buyers should request a mill test report (MTR) that confirms copper purity, tensile strength and resistivity, as well as the applicable ASTM or IEC standard (e.g., ASTM B170 for rod, ASTM B773 for sheet). Verification of dimensional tolerances and surface finish is also advisable, especially for applications in power distribution where low resistance is critical.

For security cameras, request the product data sheet that lists the IP rating, resolution, lens type and ONVIF profile, together with CE or UL certificates to confirm conformity with safety regulations. The composite video cable adapter should be accompanied by a compliance declaration covering RoHS and a test report for contact resistance. PTFE plates and boards should be supplied with a material certificate indicating the grade (e.g., PTFE‑F4), maximum continuous service temperature, and an MSDS; buyers may also ask for a dimensional inspection report.

What purity level is guaranteed for the pure copper rod?

The pure copper rod is specified as electrolytic refined copper with a minimum purity of 99.9 % Cu, as stated in the product description.

Which standards apply to the copper foil supplied?

Copper foil is listed as 99.99 % electrolytic copper and typically conforms to IEC 60384‑9 for flexible printed circuit applications.

What HS codes are used for the copper products?

The catalogue assigns HS 7407.12 to pure copper rod, 7407.11 to busbar and tube, and 7409.11/7409.19 to copper foil and sheet respectively.

What ingress protection rating do the security cameras have?

The security cameras are described as IP‑rated devices, commonly meeting IP 66 or IP 67 standards for dust and water resistance.

What material is used in the composite video cable adapter contacts?

The adapter uses phosphor bronze contacts with gold plating, housed in an ABS plastic shell, matching the listed material composition.
