Summary
In an era of increasing trade remedy scrutiny, EPC project success depends on supply chain resilience. As a lead drafter of the GB/T 6728-2025 standard, Yuantai Derun Group provides global infrastructure projects with "Audit-Ready" compliance documentation. We help EPC contractors build transparent evidentiary chains—from raw material traceability to international certification—to mitigate anti-dumping risks. Secure your structural steel sourcing and ensure seamless project delivery today.
As one of the core participating drafters of the newly GB/T 6728-2025: AD & Customs Compliance Checklist updated GB/T 6728-2025 standard, Yuantai Derun Group has firsthand, authoritative knowledge of the technical revisions introduced in China's latest specifications for cold-formed structural hollow sections. This guide explains how these recent technical revisions affect international procurement and dictates exactly which evidentiary document chains global EPC contractors must secure from their suppliers to successfully withstand aggressive anti-dumping investigations and trade regulatory customs audits.
In strict alignment with the official "Guidelines for Chinese Enterprises Responding to Foreign Anti-Dumping Investigations" issued by the Bureau of Trade Remedy Investigation of the Ministry of Commerce of China (MOFCOM), the core of any international trade defense rests on proving market-oriented raw material sourcing, transparent allocation of production costs, and adherence to top-tier technical and quality manufacturing frameworks.
The 5 Essential GB/T 6728-2025 Document Chains Required for Trade & Anti-Dumping Audits
1. Manufacturing Standards Compliance & Meticulous QC SOP Records
During foreign anti-dumping proceedings, investigating authorities routinely flag competitive export pricing to allege sub-standard manufacturing, undocumented cost-cutting, or non-compliant production processes.
The Evidentiary Power of a Standard Drafter: As of March 1, 2026, Yuantai Derun has fully updated all operational production lines to execute the rigorous parameters of GB/T 6728-2025. During the drafting and revision process of this national standard, we did not just advance the structural criteria; we seamlessly translated these statutory requirements into our daily shop-floor Quality Control Standard Operating Procedures. Possessing verified records from a "Standard Setter" provides unparalleled legal-technical defensibility before international trade tribunals.
Hardcore QC Protocols Preventing Measurement Flaws: To meet the tightened geometric tolerances of the 2025 update, our official QC logs mandate that calipers must be placed away from cut and sawed edges during physical wall thickness inspections. This specific procedure eliminates measurement interference from cutting burrs or edge deformation. Proving such meticulous, standard-aligned QC practices to customs auditors provides clear transparency, directly invalidating allegations of malicious price dumping through inferior manufacturing.
2. Raw Material Market-Oriented Sourcing & Heat Number Traceability
A primary mandate of any international customs audit is verifying that the upstream substrate chain is transparent, legal, and purchased entirely under competitive, market-driven conditions.
EN 10204 3.1 MTC Alignment: Every single dispatch batch of our GB/T 6728-2025 structural hollow sections is accompanied by a compliant EN 10204 3.1 Material Test Certificate.
Unbroken Heat Number Trailing: All MTCs must perfectly cross-reference and trace back to the original top-tier steel mill Heat Numbers, procurement contracts, commercial invoices, and bank payment swifts. This unbroken chain provides trade tribunals with ironclad proof that the core substrate material was acquired in an open market, free from non-market value distortions or hidden subsidies.
3. Allocation of Factors of Production & Financial Accounting Cost Verification
According to official MOFCOM investigation frameworks, international trade audits rely heavily on comprehensive cost transparency during official "On-the-spot Verifications."
Factors of Production Matrix: Manufacturers must readily submit itemized logs accounting for all raw material inputs, auxiliary elements, manufacturing labor wages, and exact factory utility consumption bills (water, electricity, and natural gas invoices) utilized to produce the specific structural steel. This serves as objective proof to justify the normal value of the cargo.
IFRS-Compliant Corporate Accounting: Provision of annual financial reports fully synchronized with International Financial Reporting Standards and audited by recognized independent institutions, ensuring corporate financial ledger clarity.
4. International Certifications & Cross-Border Standard Equivalence
To fulfill international customs requirements, an exporter must prove its status as an established global manufacturer with heavy fixed-asset investments and cross-border technical capability, effectively eliminating risks associated with tariff-circumvention shell companies.
Multi-Standard Compliance & Production: Our manufacturing lines are fully equipped to produce cold-formed structural steel under multiple international frameworks. Whether your project specifies the new GB/T 6728-2025, European EN 10219, or American ASTM A500, our engineering desk ensures that all chemical compositions, mechanical properties, and dimensional tolerances strictly meet the designated project benchmarks.

Global Quality Passports: We maintain active compliance certifications for ISO 9001/14001/45001 management frameworks alongside the European CE Marking for cold-formed structural steel. These official credentials—including our recognized Classification Society Certificates from ABS,KR,BV,DNV—carry substantial legal evidentiary value before global trade authorities. For a specific list of our maritime and industrial certifications, please contact YUANTAI DERUN directly.
5. Watertight Shipping & Commercial "Three-Way Match" Records
Auditors routinely cross-examine commercial and shipping documentation to exclude discrepancies, which customs offices automatically flag as transshipment or price distortion red flags.
Flawless data alignment across Commercial Invoices and Packing Lists with absolute professional accuracy.
Original Bills of Lading (B/L) paired with freight billing, legally binding Sales Contracts, and corresponding bank Swift transfer receipts to cleanly close the financial loop of the transaction.
