How to Audit and Verify Turkish Manufacturers: A 7-Point On-Site Inspection Checklist

Essential 7-step checklist for verifying Turkish suppliers before sending payments. AQL quality control, commercial registry verification, and machine capacity audits.

Why You Should Never Wire Funds to an Unvetted Overseas Factory

Every month, foreign companies experience costly procurement errors: dealing with middleman brokers posing as authentic manufacturers, receiving defective production batches, or suffering weeks of unexpected delivery delays.

At Antares Bridge, our bilingual trade inspectors are physically on the factory floor across Turkey within 24 hours. Here is our rigorous 7-Point Factory Verification Protocol:


#

Step 1: Official Chamber of Commerce & Tax Verification

We verify the company’s legal existence in the Turkish Trade Registry Gazette (Ticaret Sicil Gazetesi), checking corporate capital, official directors, tax compliance (Vergi Levhası), and verifying that the registered address matches the actual manufacturing facility.

#

Step 2: Machine Park & Production Line Inspection

We inspect the factory floor to ensure the supplier actually owns and operates the machinery required for your order, rather than subcontracting to unvetted third parties.

#

Step 3: Raw Material Traceability & Storage Conditions

Quality begins with raw materials. We inspect raw fabric rolls, stainless steel stock, or plastic pellets, ensuring proper humidity control and certification batch numbers (e.g. OEKO-TEX, ISO 9001).

#

Step 4: In-Line Process Controls (DUPRO)

When 30% to 50% of the production batch is assembled, our inspectors perform random sampling to catch stitching errors, dimensional deviations, or color shifts before bulk finishing.

#

Step 5: Pre-Shipment Inspection (PSI) to ANSI/ASQ Z1.4

Before final payment is released, we perform statistical AQL Level II sampling. Defect limits (Critical: 0, Major: 2.5, Minor: 4.0) are strictly enforced.

#

Step 6: Packaging, Barcode & Drop Testing

We inspect master cartons for burst strength, verify that Amazon FNSKU or EAN-13 barcodes scan with 100% readability, and conduct 5-point drop tests.

#

Step 7: Container / Truck Loading Supervision

Our team supervises the physical loading into the TIR trailer, verifying seal numbers, securing cargo against transit movement, and confirming count tallies.
