Fastener Export: Standards and Certification Guide

As global trade integration accelerates, China's fastener exports continue to expand, reaching the EU, the US, the Eurasian Economic Union, Japan, South Korea, and beyond. As the "rice of industry," fastener quality and compliance determine whether products can successfully enter overseas markets. International standards and export certifications serve as the essential "passport" for fastener exports.

For fastener exporters and foreign trade buyers, understanding international standards for different target regions and mastering common certification requirements are key to mitigating risks and enhancing competitiveness. Many companies face rejection or returns due to unfamiliarity with standard differences or missing certification steps, resulting in financial losses and reputational damage. This guide outlines the most critical international standards and common certifications for fastener exports, helping professionals navigate the export process smoothly.

Part 1: Core International Standards

The fundamental prerequisite for fastener exports is compliance with target market standards. Different regions and applications have significantly different requirements. International standards establish universally recognized technical specifications covering dimensions, materials, strength, and performance.

ISO Standards – Most widely used globally. ISO 898 series covers carbon and alloy steel bolts, screws, studs, and nuts (ISO 898-1/2), specifying strength grades, tensile strength, and hardness. ISO 3506 series covers stainless steel fasteners (ISO 3506-1/2), suitable for high-temperature and corrosive environments in food, medical, and marine industries.

EN Standards (EU) – Required for EU and EFTA countries. EN 14399 covers high-strength structural bolting assemblies for steel structures. EN ISO 898-1/2 align with ISO but add EU-specific compliance requirements. EU standards also include explicit requirements for surface treatment and environmental performance.

US Standards – ASTM covers chemical, mechanical, and testing requirements. ASME specifies dimensional clearance holes and terminology. SAE addresses automotive-grade fasteners with high precision, strength, and fatigue resistance. US markets strictly enforce these standards.

Eurasian and Other Standards – GOST standards (Russia and CIS countries) cover dimensions, materials, and performance. CUTR standards (EAEU) include TR CU 010/2011 (machinery safety) and TR CU 004/2011 (low-voltage equipment safety) for EAEU member states.

Part 2: Key Export Certifications

Beyond international standards, fasteners require target market certifications – official proof of compliance essential for customs clearance and market access.

CE Certification (EU) – Mandatory for fasteners used in construction and machinery. Requires compliance with the Construction Products Regulation (EU No 305/2011). Core requirements include conformity with harmonized standards (EN 14399, EN ISO 898 series), complete technical documentation, a Declaration of Performance (DoP), and CE marking on product or packaging. Compliance routes include self-declaration (low-risk) or notified body involvement (high-risk).

FDA Certification (US) – Required for fasteners used in food, medical, and pharmaceutical applications. Strict requirements for material composition, surface treatment, and hygiene – no harmful substances, mandatory sanitary testing. Automotive fasteners also require IATF 16949 certification.

EAC Certification (EAEU) – Mandatory for Russia, Kazakhstan, Belarus, and other EAEU members. Under TR CU 010/2011 and TR CU 004/2011, special-purpose fasteners (e.g., for oil production equipment) require an EAC Certificate (COC) through accredited third-party review and testing. General construction and household fasteners can use an EAC Declaration (DOC) based on self-declaration with technical documentation. Products must bear the EAC mark.

Other National Certifications – Japan requires JIS certification. South Korea requires KS certification. Australia requires AS certification.

Part 3: Compliance Best Practices

International standards and certifications must be matched correctly. Exports to the EU require both EN standards and CE certification. Food-grade fasteners to the US require both ASTM standards and FDA certification. EAEU exports require CUTR standards and EAC certification.

Complete technical documentation, test reports, and certificates must be retained for potential inspection by target market authorities.

Common Compliance Mistakes – Mistaking ISO standards as equivalent to EN standards without meeting CPR requirements; ignoring special market requirements such as US restrictions on hazardous materials or EU environmental standards for surface treatment.

Avoidance Tips – Identify the target market before exporting and precisely match corresponding standards and certification requirements. Select qualified testing and certification bodies with proven experience. Prepare complete technical documentation in advance. Monitor target market standard and certification updates regularly, adjusting production and compliance processes accordingly.
