Questions about product quality inspection
How much does product inspection cost?
Warehouse inspection starts at USD 69 for up to 20 standard sample checks, with additional standard checks from USD 0.30 each. The checklist, sample scope and any extras are confirmed before work. Site visits and specialist checks are quoted separately.
Is warehouse inspection the same as a factory visit?
No. Warehouse inspection checks an agreed sample after the goods reach the warehouse. A factory or supplier-site visit needs separate scope, location, availability and pricing confirmation.
Does a sample inspection guarantee every unit is defect-free?
No. Findings apply to the agreed checklist and sample inspected. Inspection does not replace laboratory testing, regulatory certification or checking every unit.
Can inspection be my only service?
Yes. Start with one product check without moving your entire fulfillment operation. You may add labeling, packing, storage or shipping later if needed.
How can I check a supplier batch before paying for overseas shipping?
Agree the product reference, sample count and checklist before inspection. PrepPort warehouse checks can document visible condition, agreed counts, labels, accessories and packaging with photos and findings for your decision. Standard warehouse sampling starts at USD 69 for up to 20 standard sample checks; additional standard checks start at USD 0.30 each. Factory visits, laboratory tests, certification and a full-batch AQL program are separate scopes. A sample result is not a guarantee for every unit or a legal compliance certificate.
What happens when an inspection finds defects or incorrect labels?
Keep the finding tied to the product and batch, record the agreed checks and missing evidence, and decide whether the affected goods need correction, more inspection, supplier return or shipment. Photos alone do not approve a release or prove an unperformed test passed. PrepPort scopes extra work and its cost before carrying it out. Provide your acceptance criteria and identify who can approve the next step. Refunds, compensation, certification conclusions and supplier settlement are not automatically authorized by an inspection finding.
