Procurement FAQ

Frequently Asked Technical & Logistics Questions

Essential guidance on part identification, export documents, sample verifications, and international shipping options.

How do I verify part compatibility using OEM or cross-reference numbers?

Provide any known original equipment manufacturer (OEM) part number, casting code, or competitor cross-reference. Our technical desk verifies port sizes, voltage ratings, geometric dimensions, and vehicle chassis models against master catalogs before preparing your order.

Can you source heavy-duty parts not shown on the website?

Yes. Many specialized brake valves, axle components, and transmission parts are sourced on demand. Simply send technical drawings, physical samples, or clear nameplate photos to initiate rapid supplier verification in Bursa's industrial cluster.

What export documentation do you prepare for customs clearing?

All commercial consignments include full Commercial Invoices and Packing Lists. Depending on destination, we organize A.TR movement certificates for EU-bound shipments, EUR.1 certificates, and legalized Certificates of Origin.

Are there strict minimum order quantity (MOQ) requirements?

MOQs depend on whether the item is a standard stocked unit or a custom production run. We regularly assemble mixed-product trial orders and full pallet loads across diverse categories like valves, mirrors, and lighting.

Do you support private labeling, custom packaging, and pallet consolidation?

Yes. Custom box branding, laser part-marking, and private label barcoding are supported for qualifying volumes. All items can be consolidated under one export file to streamline clearance.

What Incoterms and delivery options are available?

We operate primarily on EXW, FOB, and CIF/CIP terms via air freight for urgent fleet maintenance, full truckload (FTL) for continental Europe and the Middle East, or ocean container freight (FCL/LCL) through nearby Gemlik ports.
