Business Overview

Avg Response Time

≤ 1h

Shandong Shuangyuan Sealing Technology Co., Ltd. stands out by providing specific test reports for both double-sided butyl tape and aluminum foil butyl tape — a strong signal of product reliability and performance validation, which is critical for buyers in regulated industries like automotive or construction. REACH certification confirms compliance with EU chemical safety standards, making this supplier a trusted option for European markets. With 117 employees, the company operates at a mid-sized scale, balancing capacity with operational focus. The inclusion of both FOB, CIF, and CFR terms gives buyers flexibility in managing shipping responsibilities. Transaction terms of LC and T/T offer secure payment options, with LC being preferred by buyers needing strong financial guarantees. However, the lack of verified work email and document verification raises a red flag — buyers should request additional proof to confirm legitimacy before placing large orders. Being based in China, the origin country, provides access to cost-effective manufacturing, but buyers must validate the authenticity of the test reports and certifications to ensure product consistency.
