Quality Control Checklist for Ceramic Tableware From Bangladesh
A numbered QC checklist for ceramic tableware from Bangladesh: glaze and crazing, lead and cadmium limits, thermal shock, chips and edge strength, decoration durability, labels and packing, with fixes for common failures.
Short answer
Use this ceramic tableware quality control checklist to check shape and size, glaze and crazing, chips and edge strength, lead and cadmium results against your destination market, decoration durability, washing and heat claims, and labels and packing on tableware from Bangladesh before shipment. Agree tolerances, test methods and acceptance numbers in the purchase order.

Key takeaways
Agree the sample, tolerances, test methods and acceptance numbers before inspection, and draw the sample at random across shapes, colours and cartons.
Judge lead and cadmium results against the destination market, not one global figure, and require a report naming the same shapes, colours and glaze.
Check glaze, crazing, rims and feet piece by piece under strong light, because the faults that cause returns hide in cartons.
Hold any lot whose food-contact report does not match the lot, and re-inspect after sorting or rework rather than shipping on a promise.
If you buy plates, bowls, cups and serving pieces from Bangladesh, use this ceramic tableware quality control checklist before the shipment leaves the factory. Tableware fails in ways a general goods check misses: glaze can craze after hot food and cold water, a rim can chip in a carton, and decoration can fade in washing.
Use an agreed sampling plan rather than pieces the supplier selects. ISO 2859-1 specifies sampling schemes indexed by acceptance quality limit (AQL) for inspection by attributes.1 Write every tolerance, test method and acceptance number into the purchase order before production.
Why this checklist matters
Ceramic tableware carries three risks at once: food-contact safety, durability and appearance. A plate with a hairline glaze crack, a mug with a rough rim, or a bowl that does not stack will be returned even if its colour matches. A chip, pinhole or warped base shows only when the piece is lifted and turned.
Each point is checked against the approved sample, specification and lab report, and recorded as pass, fail or not applicable. Food-contact results are judged against the destination-market limits, not a single global figure.
Before you start
Do not begin until the references are complete: an approved sample per shape and colour, the purchase order and specification, the body type, the glaze and decoration specification, the test list per market, and the packing specification. Agree the sampling plan in advance,1 and draw the sample at random across shapes, colours, cartons and batches.
Confirm which market each lot is for first. Under Regulation (EC) No 1935/2004, food-contact materials must be made in line with good manufacturing practice so that, under normal or foreseeable use, they do not transfer constituents to food in quantities that could endanger human health, change the composition of the food, or harm its taste and smell.2 The United Kingdom regulations test uses 4% acetic acid at 22 degrees Celsius, plus or minus 2 degrees, for 24 hours, plus or minus half an hour.3 Ask the laboratory to name the test method on every report, such as ISO 6486-1 for lead and cadmium release.4
The full checklist (numbered, printable)
Shape, size and fit
Measure diameter, height and depth per shape against tolerance, and record actual values.
Check hollowware capacity against the stated volume at the specified fill level.
Set each piece on a flat surface for rocking; check lids sit flat on the rim.
Stack sampled pieces as in use, and confirm rims, feet and handles clear each other.
Check handles for size, position and grip, and that none forces the piece to tilt.
Check spouts for a clean pour, with no drips down the body.
Check that set pieces match in shape and proportion.
Body, glaze and crazing
Turn each piece under strong light and check for crazing, the fine glaze crack network, and body cracks.
Check for pinholes, blisters, glaze crawling, bare patches and rough spots, inside, on rim and foot.
Feel rims, handle joins and foot rings for sharp edges, glaze drips and rough patches.
Check glaze coverage inside hollowware and under handles, where a missed coat is easy to overlook.
Check colour and glaze finish against the approved sample under the same light, across the set.
Where crazing resistance is tested, confirm the method and result in advance. ASTM C554 covers crazing resistance of fired glazed ceramic whitewares by a thermal shock method.5
Check for warping by sighting along rims and bases, and by the flat-surface test in item 3.
Chipping and edge strength
Inspect every rim, spout tip, handle edge and foot ring for chips and flakes, turning each piece fully.
Check foot rings and bases for handling chips, and reject pieces whose foot will scratch a table.
Handle sampled pieces as a buyer would; a cracked sound or weak handle join goes to a closer check.
Check handle joins for cracks, and pull each handle gently by hand.
Record chip location and size against the defect list, because a rim chip differs from a hidden foot chip.
Food-contact safety: lead and cadmium
Confirm the destination market and its lead and cadmium limits, and that the report names the same market, shapes, colours and glaze.
Under the United Kingdom regulations, the limits by category are: articles that cannot be filled, and articles that can be filled with an internal depth of 25 mm or less, 0.8 mg per square decimetre for lead and 0.07 mg per square decimetre for cadmium; all other articles that can be filled, 4.0 mg per litre for lead and 0.3 mg per litre for cadmium; and cooking ware and storage vessels over three litres, 1.5 mg per litre for lead and 0.1 mg per litre for cadmium.3
For the United States, the FDA lead guideline by category is: flatware, averaged over six units, 3.0 micrograms per millilitre; small hollowware other than cups and mugs, any one of six units, 2.0; cups and mugs, any one of six units, 0.5; large hollowware other than pitchers, any one of six units, 1.0; and pitchers, any one of six units, 0.5.6
Confirm the report category definitions match the pieces: under the FDA guideline, flatware has an internal depth of 25 mm or less, hollowware greater than 25 mm, and small hollowware a capacity under 1.1 litres.6
Check that every report names the glaze, decoration and colour tested, because a plain plate result does not cover a decorated piece.
Treat any food-use piece without a matching food-contact report as a failure, not a general food-safe statement.
If a piece is decorative only, check it is marked or shaped so it cannot be mistaken for food ware.
Decoration, print and durability
Check printed, decal and hand-painted decoration for placement and completeness against the approved artwork.
Check that decoration does not sit where lips will touch it unless the specification and report cover that area.
Rub sampled decoration firmly by hand and, where specified, check the named wash test for fading or flaking.
Check metallic bands for even width, unbroken lines, secure adhesion, and rim wear.
Check that pattern, colour and decoration match across a set, and a replacement can be matched from the same artwork.
Function, washing and heat
Wash sampled pieces by the specified method, then check for water marks, decoration loss and glaze dulling.
Where dishwasher, microwave or oven use is claimed, check claim, care label and test evidence all name the same use.
Where a thermal-shock check is agreed, confirm procedure, temperatures and pass rule in writing first, then inspect for crazing and cracking.5
Check care instructions: intended use, heat limits, and recommended washing method, in the destination-market language.
Labels, packing and cartons
Check that care, material, origin, set-content and brand labels are present, legible, correctly positioned, and hide no fault.
Check barcodes and set-content stickers scan and match the order, and each set holds the named pieces and quantities.
Check inner packing: each piece separated so rims, handles and decoration cannot rub.
Check carton strength, count, assortment and shipping marks against the packing list, and weigh and measure sample cartons.
Open sample cartons fully, not just the top layer, because breakage concentrates at carton edges and the bottom of a stack.
Common failures and how to fix them
The most frequent failure is crazing that appears only after use, usually because glaze and body do not fit each other or firing was uneven. Stop, compare the crazed pieces with the approved sample, check the crazing test evidence,5 and only then restart the line. Next is chipping at rims and feet, from handling, stacking or packing without dividers: re-check packing on a full carton first.
Shade differences across a set point to more than one glaze batch or decal run: re-sort complete sets before packing. A report that does not match the lot is not a fault to wave through: hold the lot until a matching report is supplied. Above the agreed acceptance level, options are re-inspection after sorting or rework, documented partial acceptance, or rejection.

How Exportain helps
Exportain is a B2B marketplace connecting buyers with Bangladeshi suppliers of ceramic tableware, so the specifications behind this checklist can be agreed at the enquiry stage. Browse suppliers, read the AQL acceptance quality limit explainer, and use inspection services when you plan the check. Supplier profiles show which document and photo checks have been recorded, not factory inspections. Exportain does not inspect goods and is not a party to the goods contract.
FAQs
When should this checklist be used?
Use it at final inspection, when goods are finished and largely packed. For larger and first orders, also use it during production, while problems can still be corrected.
Who should complete it?
The buyer, a local agent or an independent inspector can complete it, using the approved sample, specification and a randomly drawn sample. Food-contact testing must be done by a laboratory, not by sight.
What are the most common failures?
Crazing, rim and foot chips, shade differences across a set, and food-contact reports that do not match the lot are the failures buyers find most often.
Can a third party do it?
Yes, if you share the approved references, tolerances, acceptance levels and test list first. See the pre-shipment inspection guide.
