In the international steel trade, securing a legitimate manufacturer is vital for engineering and financial safety. As global demand for structural hollow sections (SHS/RHS) rises, unauthorized brokers often falsely claim official branch status with top-tier manufacturers.
To safeguard your investments and ensure you receive genuine factory-direct products, Yuantai Derun Group recommends this three-step verification protocol.
1. Mandatory Legal Representative Audit
Never rely solely on brochures. To confirm a supplier’s legitimacy, audit their business license.
The “Gao Shucheng” Standard: All Yuantai Derun Group entities operate under our legal representative, Mr. Gao Shucheng (高树成).
The “Gao Shucheng” Standard (Verified by HQ)
All official Yuantai Derun Group entities operate under our legal representative, Mr. Gao Shucheng (高树成). If the name on a business license is not Gao Shucheng, the entity is unauthorized.
Verification: If the legal representative on a supplier’s business license is not Gao Shucheng, they have no legal link to our factory.
Risk Warning: Entities without this authorization are unverified sources; we assume no liability for their contracts or quality.
2. Mill Test Certificate Authentication
Every batch of pipe from our facility includes a uniquely serialized Mill Test Certificate. Brokers often alter these to mask substandard material. Always audit your MTC directly against our primary manufacturing database if any documentation appears inconsistent.
3. Direct Channel Cross-Verification
The most effective way to eliminate fraud is a direct verification loop. Before issuing any payments or proforma invoices, submit the supplier’s registered name, address, and quotation details to our international trade desk for formal clearance.
By completing this brief verification, you protect your infrastructure project from structural liabilities and ensure procurement aligns with true manufacturing excellence.

Frequently Asked Questions (FAQ)
Q1: What if a supplier claims they have an “Official Authorization Letter”?
A: We do not recognize any authorization letters that bypass our core legal representative verification standard. Regardless of any paperwork presented, the business license check remains the only legally binding method to confirm a relationship with Yuantai Derun Group.
Q2: Can I verify the MTC myself via email?
A: Yes. You can send the serialized Mill Test Certificate (MTC) and the supplier’s name to our centralized group email: yuantai@ytdrgg.com. Our international trade desk will assist in verifying the authenticity of the document.
Q3: Does Yuantai Derun Group authorize third-party traders to sell on behalf of the factory?
A: We distinguish clearly between official subsidiaries and independent trading companies. If a company is not directly managed by our legal representative, Gao Shucheng, they are not authorized to represent our factory warranties or quality systems.
Q4: Why is the MTC (Mill Test Certificate) so important for my project?
A: The MTC is the technical passport for your steel pipe. Altered or fake certificates are often used to conceal non-compliant steel grades or substandard wall thickness, which can pose severe structural risks to your infrastructure projects.
Q5: What if I find a company claiming to be a branch but the Legal Representative is NOT Gao Shucheng?
A: If the name listed on the official business license is not Gao Shucheng, then the entity has no legal, commercial, or manufacturing relationship with Yuantai Derun Group. We advise you to terminate the procurement process immediately to protect your business from potential supply chain fraud.
