Service · After delivery
After-sales continuity from China
When Sinospect supplied the order, the buyer brings an agreed warranty or supplier issue to Sinospect, which investigates it against the supply contract and available acceptance record and coordinates the contractual remedy. For a buyer-direct order, Sinospect can accept a separate evidence, supplier-follow-up or spare-parts scope. The buyer retains its supplier contract.

01 · Scope
After-sales starts from the contract and available order record
Issues may emerge during installation, commissioning or use, or when a repeat order or spare part is needed. The first step is to identify the equipment and applicable contract, then assemble the records actually available for the case. The resulting scope may be warranty administration on a Sinospect supply, buyer-direct supplier follow-up, spare-parts sourcing or repeat-order alignment.
It becomes useful when
- Equipment, moulds, packaging, components or finished goods delivered earlier need technical follow-up, replacement parts or supplier clarification.
- A warranty claim needs the technical evidence required for supplier follow-up.
- A specific spare part — bearing, control card, valve, mould insert, sensor, seal, label, carton, accessory or tool component — must be sourced from the original supplier or a verified alternative source in China.
- The client is preparing a repeat order and wants the prior specification, price basis, lead time, packing, marking and quality lessons carried forward.
- The buyer's supplier contact has changed, communication has slowed, or the supplier has become less responsive after shipment.
- The client's own procurement or operations team changes, and the institutional memory of the supplier relationship in China needs to remain accessible.
02 · Controls and evidence
Control points across the after-sales layer
Control point
Issue intake and installed-base record
Sinospect ties the after-sales issue back to the original supplier, purchase scope, specification, inspection record, serial number, shipment file and site evidence. The first step is to turn scattered feedback into a case the supplier can understand and act on.
Control point
Warranty and supplier accountability
When the issue falls under warranty or supplier responsibility, Sinospect prepares the claim, translates the technical and commercial position into supplier-facing language, follows up in Mandarin and tracks the supplier's response until the agreed next step is clear.
Control point
Spare-parts and replacement continuity
Original part references, equivalent sources in China, fit/form/function checks, lead times, minimum order quantities and shipment constraints are tracked for subsequent replacement requests.
Control point
Repeat-order and version control
Prior specifications, drawings, samples, packaging, markings, prices, lead times, corrections and non-conformities are carried into the next order to preserve the agreed product and commercial requirements.
Control point
Supplier relationship and document continuity
Supplier contacts, site visits, correspondence, inspection records, certificates, manuals, corrective actions and order history remain retrievable. The supplier relationship in China remains accessible, whether or not an order is currently active.
Evidence reviewed
Evidence captured across the after-sales layer
- Issue and warranty record
- Failure description, photos, videos, serial numbers, operating conditions and timeline organised into a supplier-facing case file.
- Original PO, specification, inspection record, shipment documents and correspondence linked to the claim where available.
- Supplier position, agreed next step, corrective action, replacement, concession or closure evidence recorded.
- Spare-parts and replacement record
- Original supplier references, part numbers, drawings, samples, dimensions, lead times and minimum order quantities recorded where available.
- Equivalent sources in China checked for fit, form, function and compatibility with the client's equipment or product.
- Packing, marking, document and shipment requirements tracked for small replacement shipments or consolidated spare-parts orders.
- Continuity and repeat-order record
- Prior specification, quotation, drawings, samples, document pack, inspection findings and non-conformities kept available for the next order.
- Changes between the previous and new order documented: version, supplier substitution, price, lead time, packaging, artwork, marking or technical adjustment.
- Supplier contact changes, responsiveness, capacity signals and relationship notes logged for future sourcing and escalation.

04 · Risks controlled
Risks controlled
Risk
A warranty claim stalls because the supplier receives incomplete evidence from site and its response is delayed.
Control response
Sinospect converts site feedback into a documented supplier-facing case, attaches the original record where available, follows up in Mandarin and tracks the agreed next step.
Risk
The wrong spare part is ordered because the original reference, machine configuration or version history is unclear.
Control response
Original order records, part references, drawings, photos and compatibility requirements are checked before the replacement path is confirmed.
Risk
The client has to rebuild the sourcing path from zero every time a bearing, control card, mould insert, label, carton or accessory is needed.
Control response
Sinospect maintains a spare-parts and replacement record tied to the original supplier and verified equivalent sources in China.
Risk
Repeat orders regress on material, brand, packaging, artwork, marking, price basis or lead time.
Control response
Prior specifications, supplier commitments, corrections and version notes are carried forward in writing before the new order is released.
Risk
Supplier responsiveness drops after shipment or after the buyer's contact person changes.
Control response
Sinospect keeps the communication channel with the supplier in China active, tracks contact changes and escalates through its supplier relationships when needed.
Risk
Institutional knowledge disappears when the buyer's procurement or operations team changes.
Control response
The order record kept in China remains organised and retrievable for warranty, spare parts, audit, regulatory, repeat-order and supplier-review questions.

06 · Questions
Frequently asked questions
Can you handle an after-sales issue if the original order was placed without Sinospect?
Sinospect reviews the available contract, specification, equipment identity and site evidence, then proposes a supplier-follow-up scope. The buyer’s contract provides the basis for the warranty claim.
Who handles the warranty claim when Sinospect supplied the order?
You bring it to Sinospect. We investigate against the agreed specification and the acceptance evidence from the order file — inspection reports, the FAT record, shipping documents. We manage the factory and any other parties involved, and coordinate the remedy agreed in your contract. Warranty duration, exclusions and remedies are project-specific and stated in the supply proposal.
And when the order was bought directly from the factory?
Warranty acceptance then depends on the contract, the specification, the evidence, the operating conditions and the supplier's own position. Sinospect documents the claim, attaches the available evidence and follows it up with the supplier in Mandarin, with the claim and supplier response kept in the case file.
What do you need from the buyer to start?
The original purchase documents if available, supplier name, product or equipment reference, serial number or model, photos and videos of the issue, operating conditions, installation context, timeline, and the buyer's preferred outcome — replacement, spare part, repair guidance, clarification, credit, repeat order or supplier review.
Can you source spare parts when the original supplier has stopped stocking them?
Yes. Sinospect first checks the original supplier, the cleanest route. When the part is unavailable, Sinospect looks for equivalent sources in China and verifies fit, form and function before proposing a replacement path. For critical parts, the buyer validates the alternative against its own equipment and site requirements.
Do you keep documentation from prior orders?
For projects Sinospect handled, yes — specifications, supplier alignment notes, inspection records, shipment documents, corrective-action history and correspondence can be retained and retrieved for after-sales, repeat-order or audit purposes. For projects that came to Sinospect after delivery, the record is rebuilt from the buyer's available documents.
07 · Getting started
