SummaryHainan Xinghe Yongyao Import and Export Co., Ltd. is a China-based trading company established in 2024 with four employees, offering Graphitized Petroleum Coke. Its registered scope covers metal-related sales, processing, transportation, and storage, but the provided information does not confirm in-house production. The supplier has an SGS audit record valid from March 17, 2025 to March 16, 2026, although the stated evaluation result is not interpretable as a pass or certification.

Supplier typeThe supplier is explicitly identified as a Trading Company and a Limited Company, with four employees and no larger-company affiliation. Its offered product is Graphitized Petroleum Coke, indicating a small independent trading organization rather than a confirmed manufacturer.

After-Sales capabilityThe supplier has procedures for corrective and preventive actions and customer complaints, but no written records are maintained. It also has no overseas agents or branches, no overseas showroom, and no reported overseas service countries, limiting documented and international service capability.

R&D capabilityInnovation capability appears limited: the supplier has one R&D engineer, launched no new products in the last year, and reports no private-mold R&D, no professional technical-supplier capability, and no 3D software design service. These explicit limitations indicate no demonstrated innovation advantage.

Customization capabilityThe supplier explicitly provides customization from samples. However, it does not provide private-mold development or 3D software design services, so customization is evidenced only at a sample-based level.
