Procurement & Technical FAQ

Frequently Asked Questions by Overseas Buyers

Essential guidance on cross-referencing, manufacturing standards, minimum order values, and export delivery processes.

How do you cross-reference original equipment part numbers?

We maintain an indexed database that pairs OEM numbers (Mercedes, Volvo, Scania, MAN, DAF, SAF, BPW) with Tier-1 engineering references (WABCO, Knorr-Bremse, Continental) and internal KNB codes. Prior to quotation, our technical team confirms thread pitch, port geometry, pressure rating, and mounting centers to eliminate interchange mismatches.

What are the lead times for custom or off-catalogue parts?

For catalog items currently in inventory, consolidation takes 3–7 business days. For specialized castings, custom forgings, or manufactured runs from our Bursa industrial partners, typical production lead times range between 3 to 5 weeks depending on metallurgy and tooling requirements.

Can you supply private label packaging and custom branding?

Yes. For distributor-level volumes, we offer custom laser engraving of client part numbers, branded carton packaging, barcode labeling, and protective anti-corrosion wrapping for sea freight. All specifications remain strictly confidential under NDA agreements.

What trade agreements and tax incentives apply when buying from Türkiye?

Due to the EU–Türkiye Customs Union, industrial goods exported to the European Union enter tariff-free with an A.TR Movement Certificate. For non-EU markets (North America, Middle East, Africa), we issue official Chamber-certified Certificates of Origin and support EUR.1 where bilateral free trade agreements exist.

What quality standards and test reports accompany the components?

Production partners operate under ISO 9001 and IATF 16949 certified quality management systems. Pneumatic valves undergo automated 100% leak tests; brake discs are balanced according to ISO 1940; lighting products hold E-Mark (ECE) approvals.

What is the policy regarding Minimum Order Quantities (MOQ)?

We work flexibly with international fleet operators, distributors, and workshops. While container loads offer the highest freight efficiency, mixed pallet orders consolidating valves, discs, hubs, and lighting units are supported without restrictive single-line MOQs.
