The Sampling Process in Imports: A Guide to Verifying Products Before a Bulk Order

Obtaining and evaluating samples before placing a bulk order abroad is one of the most critical steps in importing. A well-managed sampling process prevents quality problems, product mismatches and financial losses.

Have Your Import Risks Checked Before Ordering

Let's assess your product's HS code, duty, surveillance, anti-dumping, TAREKS, document, supplier and total cost risks together before you order.

Why Is the Sampling Process Important?

Taking samples before a bulk order minimises these risks:

Quality mismatch: The product not meeting expected standards
Technical differences: Differences in size, material, colour or performance
Regulatory non-compliance: CE, TAREKS or other regulatory requirements not being met
Packaging and labelling problems: Packaging that does not comply with Turkish regulations
Supplier reliability: Verifying the supplier's production capacity and quality consistency

Types of Samples

Existing Sample

A sample of the standard product the supplier already manufactures. It gives an idea of overall quality and the supplier's production capability.

Custom Sample

A custom-made sample requested by the importer by sending technical drawings, specifications or a reference product. It is used for final approval before series production.

Golden Sample

The final sample approved by both parties before series production and kept as a reference. Bulk production is carried out according to this sample.

Pre-Shipment Sample

Random samples taken after bulk production is complete and before shipment. They verify that series production matches the golden sample.

Sample Evaluation Criteria

When a sample arrives, the following criteria should be evaluated systematically:

Technical Specifications

Size and dimensions (within tolerance?)
Material composition and quality
Colour and surface quality
Weight and density
Mechanical/electrical performance

Regulatory Compliance

CE marking and declaration of conformity
Compliance with Turkish technical regulations
Labelling requirements (Turkish label, content information)
Safety standards

Packaging and Labelling

Inner and outer packaging quality
Adequate protection during transport
Accuracy and regulatory compliance of label information
Barcode and traceability information

Functional Tests

Whether the product works as designed
Durability and lifetime tests
Safety tests
Resistance to environmental conditions

Steps of the Sampling Process

1. Sample Request

Send the supplier a clear, written sample request specifying:

Number of samples required
Technical specifications and reference documents
Sample cost and courier responsibility
Expected delivery time

2. Sample Receipt and Inspection

When the sample arrives, carry out a systematic inspection:

Visual check
Measurement and testing
Regulatory compliance check
Comparison with the reference product

3. Feedback and Revision

Report the required corrections to the supplier in writing. If critical corrections are needed, request a revised sample.

4. Sample Approval

When all criteria are met, the sample is approved in writing. The approved sample is kept as the "golden sample" and becomes the series production reference.

5. Production and Pre-Shipment Inspection

After series production starts, random samples are taken before loading to verify conformity with the golden sample. Our sample and product verification service provides professional support at this stage.

Common Mistakes in the Sampling Process

Placing a bulk order without a sample
Not defining evaluation criteria in advance
Giving verbal approval (written approval is essential)
Not keeping a golden sample
Ignoring differences between the sample and series production
Deciding on a single sample (at least 2-3 samples should be taken)
Seeing sample costs as unnecessary

Samples and Supplier Verification

The sampling process is an important part of supplier verification. Sample quality directly reflects the supplier's:

Production capacity
Quality control system
Communication and response time
Technical competence

Problems during sampling can turn into bigger problems in the bulk order.

Customs Procedures for Samples

Customs regulations contain special provisions for import samples. Samples without commercial value may be exempt from customs duty under certain conditions, but there are limits on sample quantity and value.
