This is the reference sheet we send buyers who want the numbers before they approve artwork.<\/p>\n\n<h2 class=\"wp-block-heading\">Capacity: Brim, Usable and What You Actually Sell<\/h2>\n\n\nThis is the first place orders go wrong. A mug sold as 11 oz holds 325 ml to the brim, but only 280-290 ml of usable volume once you leave 1.5-2 cm of headspace, which is what a cafe actually pours. The same gap runs through the range: an 8 oz mug is 237 ml brim and about 205 ml usable, a 12 oz is 355 ml and about 305 ml, a 15 oz is 444 ml and about 385 ml, and a 20 oz is 591 ml and about 510 ml. Usable capacity lands at 85-88% of brim in almost every shape, and a thick-walled or heavily tapered body pushes it lower. Weight follows the same curve: an 11 oz mug runs 320-360 g unfilled and a 15 oz runs 420-470 g. Quote both figures on the artwork sheet, because a buyer who measures 280 ml will not accept &#8220;the box says 11 oz&#8221; as an answer.\n\n\n<h2 class=\"wp-block-heading\">The Five Tolerances Worth Writing Into a PO<\/h2>\n\n\nFive numbers do most of the work in a ceramic mug order. Fired rim diameter: plus or minus 2%, which is plus or minus 2.6 mm on an 80 mm rim, and the figure that decides whether a lid or a coaster still fits. Height: plus or minus 1.5 mm, because a 2 mm step is visible when six mugs sit in a row. Capacity: plus or minus 3%, which on an 11 oz mug is roughly 10 ml and is what keeps a printed capacity claim defensible. Wall thickness: 3.5-4.5 mm on the body and 8-12 mm on the handle, since a thinner wall chips at the rim while a thicker one adds freight for no benefit. Handle attachment: a 5 kg static pull test on the finished piece. Glaze safety belongs on the same page as a pass or fail rather than a tolerance: lead and cadmium limits tested on the finished glaze, not on the raw material.\n\n\n<h2 class=\"wp-block-heading\">Cartons, CBM and the Container Sum<\/h2>\n\n\nCarton maths decides whether a container closes. A master carton of 36 individually boxed 11 oz mugs measures about 520 x 380 x 400 mm, which is 0.079 CBM, and weighs roughly 14 kg. A 20GP carries about 28 CBM usable once dunnage and door clearance are allowed for, so it takes roughly 350 cartons, or 12,600 mugs. A 40HQ carries about 68 CBM usable and takes roughly 860 cartons, or 30,960 mugs; at 14 kg each that is about 12 tonnes, inside the payload. Bulk packing without inner boxes moves everything: 48 pieces in a carton of about 0.10 CBM gives roughly 280 cartons on a 20GP, or 13,400 mugs. Work the sum as usable CBM divided by carton cube, then round down 5% for pallets and gaps. Assuming 0.06 CBM instead of 0.079 is a 30% error, and that error arrives as a rolled booking.\n\n\n<h2 class=\"wp-block-heading\">Lead Time by Stage<\/h2>\n\n\nLead time is four stages, and the total is the number that belongs in the contract. Sampling runs 7-12 days for a stock shape and 10-15 days when a new mould is involved, and the clock stops until artwork is approved in writing. Production runs 25-35 days for 10,000 to 30,000 pieces; the same order placed in the pre-holiday window from October can run 40 days. Cartoning and inspection adds 5-7 days before the vessel books, because inspection happens after packing rather than before it. Sea freight from China runs 30-38 days to the US East Coast and 28-35 days to Northern Europe, port to port. Add the four stages and a first order placed today is typically a 70-90 day exercise door to door. The stages that actually slip are artwork approval, a glaze batch that has to be re-run, and vessel space in peak season, not the firing.\n\n\n<h2 class=\"wp-block-heading\">Where the Unit Cost Sits<\/h2>\n\n\nOn a plain-glazed 11 oz mug the factory cost splits in a fairly stable way. Clay and glaze account for 18-25%, forming 12-18%, firing 12-15%, decoration 10-20%, packaging 8-12%, and the remainder covers QC, overhead and margin at 20-25%. Two lines move the unit cost more than anything else, and both sit on the outside of the mug: decoration and packaging. A one-colour screen print sits at the bottom of the decoration band while multiple decals or hand-painting sit at the top, and a moulded pulp divider inside the carton can add more per piece than the print itself. That is a trade worth making deliberately. If the artwork is simple, spending the difference on packaging rather than on a heavier print lowers the breakage claim, and replacing a broken mug costs far more than the heavier carton does.\n\n\n<h2 class=\"wp-block-heading\">Three Ways These Numbers Stop Adding Up<\/h2>\n\n\nThree failures repeat across almost every first order. First, brim capacity quoted as usable capacity: the buyer measures 280 ml in a mug billed as 11 oz and the return rate follows, so write both figures on the spec sheet. Second, carton cube taken from a previous supplier: 0.06 CBM instead of 0.079 is a 30% shortfall and the load plan fails at the port, so ask for the measured carton rather than the nominal one. Third, glaze colour drifting between batches: a second shipment that reads slightly greener beside the first gets returned even though every piece passes inspection on its own, so hold Delta E under 1.5 and approve a retained sample, then test each new batch against that sample instead of against a photograph.\n\n\n<h2 class=\"wp-block-heading\">Put the Numbers in the Purchase Order<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">A mug order is a set of numbers before it is a design. Brim and usable capacity, five tolerances, a measured carton cube, four lead-time stages and a cost split that names decoration and packaging are enough to make a first order predictable, and they give an inspection report something concrete to measure against. <a href=\"https:\/\/kmceramic.company\/fr\/boutique\/\" target=\"_blank\" rel=\"noopener\">D\u00e9couvrez notre gamme de mugs<\/a> and ask for the specification sheet per SKU, because that sheet is the part of the order that survives the email thread.<\/p>","protected":false},"excerpt":{"rendered":"<p>If your purchase order says &#8220;11 oz mug, 36 per carton&#8221; and nothing else, you have already handed control of the outcome to whoever packs it: usable capacity is not brim capacity, a carton cube quoted from memory is how containers get rolled, and a tolerance nobody wrote down cannot be enforced at inspection.
