Short answer: A greenhouse pre-shipment inspection should verify identity, quantity, dimensions, material and coating specifications, equipment models, workmanship, function tests, packing and document traceability against the approved contract and bill of materials. The inspection plan must be agreed before production because not every requirement can be checked after packing.
State who inspects, when notice is given, which documents are used, what sampling method applies and how nonconformities are handled. Clarify whether inspection is performed by the buyer, a third party or the supplier's quality team. Any certificate or laboratory test should be listed explicitly; buyers should not assume it is automatically provided.
| Stage | Possible checks |
|---|---|
| Incoming materials | Identity, specification, dimensions and required records before fabrication. |
| In-process fabrication | Cutting, holes, weld appearance, jigs, sample dimensions and coating preparation. |
| Finished structure | Member labels, connection fit, dimensions, surface condition and sample assembly where agreed. |
| Equipment | Nameplate, model, voltage, accessories, rotation or functional checks when practical. |
| Packing | Quantity, protection, package marks, moisture control and container loading sequence. |
The inspector should have the signed quotation or contract scope, approved drawings, bill of materials, equipment data sheets, packing requirements and agreed inspection criteria. Record revision numbers. Comparing goods with an outdated offer can create false shortages or miss an approved change.
Verify representative member dimensions, hole positions, connection plates, bracing parts, gutters, vent components and other fabricated items. Review material or coating records only where contractually required and available. Visual appearance alone cannot confirm every material property, so the inspection method should match the requirement.
Check covering type, identification, dimensions and quantity against the approved scope. Confirm film-lock parts, profiles, seals, fasteners, repair materials and installation accessories. Fragile panels or glass require packing protection and clear handling marks. Replacement and spare quantities should be listed separately.
Compare fans, pumps, motors, gearboxes, controllers, sensors, dosing equipment and water-treatment components with approved data sheets. Record model, electrical rating and quantity. Where practical, witness rotation, opening, closing, leak or control checks. Some systems can only be fully commissioned after installation, water, power and field wiring are available.
Each issue should have a unique number, description, photo, drawing or specification reference, responsible party, proposed action and close-out evidence. Classify whether the item must be corrected before packing, can be accepted by written concession or needs replacement. Do not rely on verbal promises after the container is sealed.

No. The decision depends on project risk, value, buyer resources, contract terms and the inspection capability of each party.
No. Factory checks can verify components and selected functions, while full integrated testing usually requires site installation and commissioning.
The sampling plan should be agreed from item criticality, quantity, manufacturing process and contract requirements rather than assumed universally.
Record it formally, agree corrective action and verify close-out before shipment or written acceptance.
