What Certifications Should a Chinese Aluminum Window Manufacturer Have for Export?<\/h2>\n\n

When sourcing aluminum windows from a Chinese manufacturer for export<\/strong>, certifications are your assurance of quality, safety, and compliance. The specific certifications required depend on your target market, but there are universal standards every credible factory should meet.<\/p>\n\n

Runheng, as a Hong Kong-headquartered manufacturer with 31 years of export experience, holds certifications aligned with international building standards. Below is a guide to the certifications you should look for in a Chinese aluminum window factory.<\/p>\n\n

Universal Certifications<\/h2>\n\n

ISO 9001: Quality Management<\/h3>\n

The baseline certification for any serious manufacturer. ISO 9001 certification indicates the factory has documented quality management procedures covering design, production, inspection, and delivery.<\/p>\n\n

Material Certifications<\/h3>\n

Aluminum profiles should meet GB\/T 5237<\/strong> (Chinese national standard for aluminum building profiles) and preferably BS EN 755<\/strong> or ASTM B221<\/strong> standards. Runheng uses only Grade 6063-T5 and 6063-T6 aluminum alloy from certified mills.<\/p>\n\n

Market-Specific Certifications<\/h2>\n\n

CE Marking (European Market)<\/h3>\n

For export to the EU, windows require CE marking under EN 14351-1<\/strong>. This covers: air permeability (EN 1026\/12207), water tightness (EN 1027\/12208), wind load resistance (EN 12211\/12210), thermal transmittance (EN 10077\/673), and acoustic performance (EN 20140\/717-1). The CE marking must be supported by a Declaration of Performance (DoP) from an EU-recognized notified body.<\/p>\n\n

British Standards (UK Market)<\/h3>\n

The UK continues to use BS 6375<\/strong> series for window performance (Part 1: air permeability and water tightness, Part 2: wind load resistance, Part 3: acoustic performance) alongside PAS 24<\/strong> for enhanced security where required.<\/p>\n\n

ASTM Standards (North American Market)<\/h3>\n

For the US and Canada, windows should comply with AAMA\/WDMA\/CSA 101\/I.S.2\/A440<\/strong> and be tested for AAMA 2603\/2604\/2605<\/strong> for finish durability. Hurricane-prone regions additionally require TAS 201\/202\/203<\/strong> (Florida) or ASTM E1886\/E1996<\/strong> (impact resistance).<\/p>\n\n

Middle East and Southeast Asia<\/h3>\n

Many projects in these regions reference British Standards or ASTM, with local adaptations. The UAE, for example, follows Dubai Municipality regulations closely aligned with BS standards.<\/p>\n\n
