The way your inspection provider charges affects more than your invoice — it shapes how you plan QC budgets, how many inspections you actually run, and how quickly you can scale your sourcing. Here is how the two main pricing models compare.
A single, all-inclusive price per man-day (or per inspection). The rate covers the inspector, travel to the factory, a detailed photo report, and all standard quality checks. No hidden fees, no post-inspection surcharges. Flat-rate firms like Tetra Inspection use this model to give importers complete cost predictability.
The traditional model used by large TIC corporations (testing, inspection, and certification firms) and some digital platforms. A base daily rate covers the inspector's time, but additional charges may apply for travel, rush scheduling, extra samples, specialized testing, or enhanced reporting.
Neither model is universally better — each has strengths depending on your inspection needs, volume, and compliance requirements.
Know your exact inspection cost before you book. One price per man-day covers everything — no surprises on the invoice.
Inspector travel to the factory is included in the flat rate, even for factories outside major manufacturing hubs.
Photo-heavy reports with 100+ images, defect classification, and pass/fail recommendations are standard — not an add-on.
Book one inspection or one hundred. Pay-as-you-go with no annual contracts, minimum order volumes, or setup fees.
Custom contract terms, dedicated account teams, and scope adjustments mid-project for complex, multi-phase programs.
Large TIC firms bundle lab testing, certification, and inspections under a single contract — useful for compliance-heavy industries.
Firms operating in 100+ countries bring deep knowledge of local regulations, import requirements, and certification standards.
Combine inspections, audits, lab testing, and certification under one vendor agreement for simplified procurement.
The quoted rate is only part of the picture. Here is what real-world inspection costs look like under each model.
| Scenario | Flat-Rate | Per-Day | Notes |
|---|---|---|---|
| Single Pre-Shipment Inspection | $268–$348 all-inclusive | $289–$400+ base rate, plus potential travel and reporting fees | For a standard one-day inspection at a factory in Guangdong, China. |
| 10 Inspections per Month (Multi-Supplier) | $2,680–$3,480 total (volume discount often available) | $3,200–$5,000+ depending on locations and add-ons | Spread across 6 suppliers in China and Vietnam. Flat-rate pricing scales linearly with no hidden multipliers. |
| Factory Audit + Lab Certification Bundle | $268–$600 for the audit (lab testing quoted separately by lab partner) | $1,500–$3,000+ bundled project rate | When you need both a factory audit and accredited lab certification, a TIC firm's bundled pricing can be more convenient. |

Spread across 6 suppliers in China and Vietnam. Flat-rate pricing scales linearly with no hidden multipliers.
When you need both a factory audit and accredited lab certification, a TIC firm's bundled pricing can be more convenient.
The advertised inspection rate rarely tells the full story. Many providers list a competitive base rate but add charges that increase the final cost by 20–40%. Before committing to a provider, ask about these common add-ons:
With flat-rate pricing, most of these are included in the base rate. Always ask for a total-cost breakdown before comparing providers.
The right pricing model depends on your inspection volume, compliance needs, and how many countries you source from.
High-frequency inspections with FBA-specific checklists. Predictable per-inspection costs help maintain margins on tight product economics.
No minimum commitment, pay-as-you-go pricing, and consultative support. Start with one inspection and scale as your sourcing grows.
Custom SOPs per product line, supplier analytics, and volume discounts. The flat-rate model keeps QC costs predictable as you scale.
Complex programs needing accredited lab testing, regulatory certification, and global compliance audits benefit from a TIC firm — often alongside a flat-rate partner for operational QC.
Both flat-rate specialists and regional agencies serve China well. Choose based on report quality, scheduling speed, and whether you need analytics and trend tracking.
Flat-rate inspection pricing means you pay a single, all-inclusive price per man-day (or per inspection) regardless of factory location, product type, or order size. The price covers the inspector, travel, reporting, and all standard checks. There are no hidden fees or post-inspection surcharges. Flat-rate firms like Tetra Inspection use this model to give importers complete cost predictability.
Per-day (or project-based) pricing is the traditional model used by large TIC corporations and some regional agencies. The base rate covers the inspector's time, but additional charges may apply for travel, rush scheduling, extra samples, specialized testing, or detailed reporting. The final invoice can exceed the quoted rate depending on scope changes during the inspection.
It depends on your situation. For straightforward product inspections with predictable scope, flat-rate pricing is almost always cheaper because there are no add-on charges. For complex projects requiring specialized equipment, accredited lab testing, or multi-day audits, per-day pricing from a TIC firm may offer more flexibility. The key question is not which rate looks lower on paper, but what your total cost will be after all fees are included.
Yes. Many brands start with per-day providers and switch to flat-rate specialists as their inspection volume grows and they want more cost predictability. The transition is straightforward — you provide your product specs and quality requirements, and the flat-rate firm builds custom checklists for your program. There are typically no contracts or minimum commitments with flat-rate providers like Tetra Inspection.
