A useful inspection checklist begins with an approved product specification. Without agreed requirements for shape, color, artwork, finish and packing, an inspector can count defects but cannot determine whether the shipment matches the buyer’s order.
The checklist below helps importers, wholesalers and brand owners prepare for sample approval, production control and pre-shipment inspection of melamine tableware.
For the standards behind these checks – the AQL accept and reject numbers, how defects are classified and the physical tests worth running – see our melamine QC standards guide.
Before Production
Confirm the documents and samples that will define the order:
- Approved physical sample
- Product drawing or dimensions
- Material requirement
- Color reference
- Final decal artwork
- Logo and bottom-mark position
- Surface finish
- Set composition
- Packaging specification
- Labels and carton marks
- Inspection standard and AQL where required
The buyer and factory should use the same version of each file. Changes made after approval need to be recorded before production continues.
Incoming Material Checks
Incoming control verifies that materials and supporting information meet the production requirement before use. Depending on the factory system and product, checks may include:
- Supplier and material identification
- Batch or lot information
- Color or material consistency
- Packaging condition
- Supplier inspection documents
- Storage and traceability records
Product-specific food-contact reports should be reviewed separately against the material, decoration and destination market.
Molding Inspection
During molding, operators and inspectors check the product against the approved shape and process requirements. Typical points include:
- Complete forming of the product
- Overall shape and flatness
- Surface condition
- Rim and edge formation
- Visible cracks, chips or material defects
- Product dimensions and weight where specified
- Stability on a flat surface
The exact tolerance must come from the approved specification. General descriptions such as “standard size” are not measurable inspection criteria.
Decal and Decoration Checks
Printed decoration is a frequent source of visible variation. The inspection standard should identify what is acceptable for placement, color and appearance.
Check:
- Correct artwork version
- Pattern orientation and position
- Color against the approved sample
- Logo placement
- Registration between design elements
- Wrinkles, bubbles or incomplete transfer
- Stains, marks or contamination
- Surface coverage and finish
For a coordinated set, compare pieces together. A plate and bowl may be individually acceptable but look inconsistent when displayed as one collection.
Grinding and Edge Finishing
Edges should be checked for safe, consistent finishing and for visual defects created during grinding or polishing.
Inspection may cover:
- Sharp or rough areas
- Chips and cracks
- Uneven edge profile
- Grinding marks
- Residue or dust
- Consistency between pieces
Handles, raised details and specialty shapes may require additional checkpoints.
Finished-Product Inspection
The final product is compared with the approved sample and written specification. A practical checklist includes:
- Product identity and item number
- Shape, dimensions and color
- Decal and logo
- Glossy or matte finish
- Cleanliness and odor
- Surface scratches or marks
- Stability and fit
- Quantity and set composition
- Overall workmanship
Functional checks should be defined for the actual product. Do not add test methods or acceptance limits unless they are relevant and agreed.
Packaging Inspection
Packaging errors can make otherwise acceptable products unsuitable for retail or import. Verify:
- Correct product and quantity per box
- Dividers and protective components
- Product orientation and fit
- Box artwork and version
- Barcode and labels
- Country-of-origin and buyer-supplied text
- Carton quantity
- Carton marks and item number
- Carton closure and condition
- Pallet requirements where applicable
Compare barcode data and printed text with the buyer-approved file, not only with a previous shipment.
AQL and Defect Classification
When AQL sampling is used, the buyer and supplier should agree on the inspection level, AQL values and defect categories before production.
Defects are commonly classified as critical, major or minor, but the definitions must reflect the product and buyer requirements. A cosmetic mark may be minor in one program and major in a premium retail collection.
The inspection company should receive the approved sample, specification, packing file and defect criteria before visiting the factory.
Pre-Shipment Inspection
A pre-shipment inspection is normally carried out when production and packing are sufficiently complete. The inspector may verify:
- Available quantity and production status
- Randomly selected units and cartons
- Workmanship and measurements
- Artwork, labels and packing
- Carton quantity and marks
- Agreed on-site tests
- Photos and findings by defect category
The buyer should define how failed findings will be reviewed and whether rework or reinspection is required.
Test Reports and Factory Audits
Product inspection, food-contact testing, quality-system certification and social-compliance audits serve different purposes. A good pre-shipment result does not replace a product test report, and an audit does not guarantee that every shipment meets its specification.
Review these elements together as part of supplier qualification. See our melamine dinnerware quality control and compliance page and public certificates for more information.
Frequently Asked Questions
Who should prepare the inspection checklist?
The buyer should define commercial and market requirements, while the factory confirms measurable production criteria. A third-party inspector can help translate the agreed standard into an inspection protocol.
Is a golden sample enough?
No. A physical sample is important, but dimensions, artwork versions, packing and tolerances should also be documented.
When should AQL be agreed?
Before production. The supplier and inspection company need the acceptance criteria in advance.
Can an importer arrange an independent inspection?
Yes. The booking process, inspection scope, timing and cost responsibility should be agreed with the factory as part of the order.
