नमूना और उत्पादन-बैच संगति

Direct decision rule

An attractive sample is not a production control. Approve a golden sample and a written specification, then inspect against both before shipment.

Use this stage when

• The sample was handmade, sourced from stock or supplied before final certification.
• Components, firmware, packaging or accessories may change between batches.
• The order includes private-label, localization or market-specific variants.

Evidence to collect

• Signed golden sample, model specification and approved change history.
• Critical component, firmware, packaging and accessory requirements.
• Pre-production sample and agreed inspection or acceptance plan.
• Batch, serial, date-code and non-conformance records.

Decision checklist

• Freeze the model, revision, color, plug, firmware and packaging.
• Define which changes require written importer approval.
• Set inspection timing, sample size, defect limits and remedies.
• Retain reference samples from the inspected production batch.

Risks and exceptions

Requirements vary by product, destination market, Incoterm and the legal structure of the transaction. Public information is a screening input, not a substitute for current legal, customs, tax, compliance or laboratory advice for the exact product and market.
