Contract models
Sinospect can supply the order, run an agreed scope on a buyer-direct manufacturer contract, or perform one bounded control. The equipment checks are similar; contract, payment authority and remedies differ.
The buyer retains specification, design decisions, deviation approval and final acceptance unless a specific written delegation states otherwise.
Compare the three models
Three relationships
Supply is the standard route. The two secondary models remain available when the buyer needs to keep the manufacturer contract or commission one control independently.
Primary model
Sinospect contracts and invoices as the buyer-facing supplier. It qualifies the manufacturer, controls its own factory release and coordinates the delivery scope stated in the proposal.
The buyer keeps the project specification, approved deviations and final acceptance.
Request a supply proposalSecondary model
The buyer contracts and pays the manufacturer directly. Sinospect is appointed separately to run the named qualification, technical, production, inspection or documentation scope.
Manufacturer warranty and commercial remedies remain under the buyer’s factory contract.
Scope buyer-direct executionSecondary model
The buyer otherwise manages the order and commissions a defined assignment such as supplier qualification, technical review, FAT or pre-shipment inspection.
The appointment defines Sinospect’s deliverables and decision authority.

| Decision point | Sinospect supply | Buyer-direct execution | Specific control |
|---|---|---|---|
| Manufacturer contract | Sinospect contracts the manufacturer and supplies the buyer. | The buyer contracts the manufacturer directly. | The buyer keeps its existing manufacturer contract. |
| Manufacturer payment | Sinospect controls payments under its manufacturer contract. | The buyer retains all manufacturer payment authority. | The buyer retains all manufacturer payment authority. |
| Sinospect role | Buyer-facing supplier and coordinator for the agreed order scope. | Separately appointed execution partner for the agreed programme. | Provider of the one named factory-control assignment. |
| Buyer retained authority | Specification, design, deviations and final acceptance. | The same, plus manufacturer contract and payment decisions. | All order decisions outside the bounded assignment. |
| Release and final acceptance | Sinospect controls its manufacturer release; the buyer keeps final acceptance. | Sinospect reports or recommends within scope; the buyer decides manufacturer release and final acceptance. | The signed contracts define the report’s effect; the buyer keeps the decisions. |
| Warranty and remedies | The buyer brings agreed warranty issues to Sinospect; terms remain proposal-specific. | Manufacturer remedies remain under the buyer’s direct contract. | The warranty on the goods stays with the supply contract. |
| Best fit | A buyer wants one accountable supply contract and the controls behind it. | A buyer must keep the manufacturer contract but needs continuing execution support. | A buyer needs one independent, bounded control on an otherwise managed order. |
What stays with the buyer
The commercial relationship changes. These operating requirements remain explicit in the proposal.
The equipment, factories, dates, disciplines, instruments, deliverables, travel and exclusions are named before work starts.
The buyer keeps design authority, deviation approval and final acceptance.
Where law, certification or procurement rules require an accredited inspection body or notified body, the appropriately authorised party must be appointed.
Project-specific evidence is shared only with the parties authorised for the assignment. Other buyers’ and suppliers’ operational files remain confidential.
