Frequently Asked Questions
Answers to common inquiries regarding European customs regimes (0% duty A.TR), lead times, structural Eurocode 9 compliance, and MOQ.
SolarAlu (by SerProfil) is a specialized solar mounting manufacturer operating out of Istanbul and the Dilovasi / Gebze industrial hub in Turkey. We operate modern extrusion lines with an annual capacity of 12,000 metric tons, dedicated to European, Middle Eastern, and North African export markets.
No. SolarAlu operates exclusively as a B2B manufacturer supplying solar EPC contractors, solar distributors, commercial installers, and utility project developers. Products are supplied in master bundles, full pallets, truckloads (FTL), or full containers (FCL).
All structural products carry CE marking under EN 1090-1 / EN 1090-3 (Execution Class EXC2), Eurocode 9 (EN 1999-1-1) design calculations, Qualanod certified anodizing, ISO 9001:2015, and EN 10204 3.1 mill test certificates.
Under the European Union – Turkey Customs Union agreement, industrial goods manufactured in Turkey are admitted into all 27 EU member states with 0% customs duty when accompanied by an A.TR Movement Certificate.
Chinese aluminum extrusions face EU anti-dumping tariffs between 21.2% and 32.1% plus long maritime transit times (45–60 days). In contrast, Turkish profiles enter duty-free (0%) via A.TR, reach European job sites in 4–6 business days by road trailer or Ro-Ro, and carry significantly lower carbon footprints under the EU Carbon Border Adjustment Mechanism (CBAM).
Full Truck Load (FTL) and Full Container Load (FCL) orders processed under the official Turkish export customs regime are invoiced at 0% VAT (VAT exempt). For smaller trial batches or samples, flexible EXW factory pickup with standard invoicing is available.
