Longkou Sunshine Machinery Equipment Co.,Ltd

Longkou Sunshine Machinery Equipment Co., Ltd. has been in business since 2003, showing a long-standing presence in the market and likely experience in manufacturing and supplying XPS boards. However, none of the key verification points — work email, phone, account email, or business documents — are verified, which raises concerns about legitimacy and trustworthiness for international buyers. In B2B trade, verified contact details and documents are essential to confirm a company's real existence and ability to fulfill orders. Without these, buyers may hesitate to place large orders or share sensitive requirements. Being based in China gives access to a strong manufacturing base, especially for insulation materials like XPS boards, but the lack of verification could offset that advantage. Buyers should request additional proof before engaging with this supplier.
