Your products are unique — your inspections should be too. Tetra builds custom checklists, AQL criteria, and inspection SOPs tailored to your exact brand standards, then enforces them consistently across every factory and country in your supply chain.
We don't hand you a generic checklist and call it done. Our process ensures your exact quality standards are documented, tested, and enforced at every factory — with the same rigor, every time.
We work with you to document your product specifications, quality standards, and acceptable tolerance levels. If you already have internal QC documentation, we adapt it. If you don't, we help you build it from scratch.
Our QC team translates your criteria into structured inspection checklists — covering dimensions, materials, functionality, workmanship, labeling, packaging, and any compliance standards specific to your products.
Every inspector assigned to your account is briefed on your specific standards, defect criteria, and quality expectations. They know exactly what to look for — because your checklist tells them, not a generic industry template.
The same custom checklist is applied consistently whether your products are manufactured in Shenzhen, Dhaka, or Istanbul. Every factory is held to the same standard, with the same criteria, in the same report format.
Every element of the inspection checklist is tailored to your products and standards. Here are the most common customization areas.
Define what counts as a critical, major, or minor defect for your specific product. A scratch that is minor on industrial hardware might be critical on a luxury cosmetics case — your checklist reflects your standards.
Custom checks for your brand's packaging requirements — logo placement, color matching, insert orientation, seal integrity, barcode readability, and retail-ready presentation.
If you sell through Amazon, Walmart, Target, or other retailers, we build their specific compliance requirements into your checklist — labeling, packaging specs, routing guidelines, and prep standards.
Choose the right Acceptable Quality Level for each defect type based on your product category and risk tolerance. We recommend AQL levels and explain the tradeoffs between tighter and looser sampling.
Custom functional tests specific to your product — Bluetooth pairing, motor operation, water resistance, weight capacity, electrical output, or any measurable performance specification.
Specified tolerance ranges for critical dimensions — length, width, depth, weight, thread pitch, hole diameter, or any measurement that affects fit, function, or appearance.
Many brands — especially startups and first-time importers — come to us without any formal quality control documentation. No inspection checklists, no AQL standards, no defect classification criteria.
That's normal, and it's exactly what we help with. Our QC team works with you to define what "good" looks like for your products, then translates that into a structured checklist your inspectors can enforce consistently.
The result is a documented quality standard that grows with your brand — ready for new products, new suppliers, and new markets.
| Aspect | Custom SOP Inspection | Generic Template Inspection |
|---|---|---|
| Checklist | Built around your product specifications and brand standards | Industry-standard template applied to all products |
| Defect Criteria | Your definition of critical, major, and minor defects | Default defect classification that may not match your standards |
| AQL Levels | Selected based on your product risk and quality tolerance | Standard AQL levels applied uniformly |
| Inspector Briefing | Briefed on your specific products, standards, and expectations | General knowledge of the product category |
| Cross-Factory Consistency | Same checklist enforced at every factory in every country | May vary by inspector interpretation |
| Relevance | Every check point is relevant to your products | May include irrelevant checks and miss product-specific risks |
Yes. If you already have internal QC documentation — quality manuals, inspection procedures, defect catalogs, or specification sheets — we adapt them into our inspection checklist format. Your standards become the inspection criteria. We can also incorporate retailer-specific requirements (Amazon, Walmart, Target) or industry standards (ISO, ASTM, EN) alongside your custom specifications.
That is completely normal — especially for startups and first-time importers. Our QC team helps you build product-specific inspection criteria from scratch. We start with your product specifications, samples, and quality expectations, then develop a structured checklist covering dimensions, materials, workmanship, functionality, labeling, and packaging. Many of our clients started with zero QC documentation and now have comprehensive inspection programs.
Very consistent. Your custom checklist is the single source of truth for every inspection — regardless of the inspector, factory, or country. Every inspector is briefed on your specific standards before the inspection. The checklist defines exactly what to check, how to measure it, and what constitutes a pass or fail. This eliminates the subjectivity that comes with generic "use your judgment" inspection approaches.
We recommend reviewing your checklist whenever you introduce a new product variant, change suppliers, modify specifications, or identify new defect patterns. For ongoing quality programs, quarterly reviews ensure your checklists stay current with any changes in your products, suppliers, or compliance requirements. Updates are included in your program — no additional charges.
Absolutely. Most brands have multiple checklists — one per product category or even per SKU. A garment checklist will have different criteria than an electronics checklist. Similarly, a new supplier might have additional verification points that an established supplier does not need. We manage all of your checklists centrally and assign the correct one to each inspection automatically.
Custom SOP inspections use the same flat-rate pricing as all Tetra inspections — starting from $240 per man-day. There is no surcharge for custom checklists, no setup fee, and no additional cost for checklist development. Building your custom inspection criteria is part of our standard onboarding process.
