8 checks before you approve a mug sample

The decisions that cost the most are the ones taken late. This issue is the eight-point check we run before a sample is signed, and the four guides that sit behind it.

The short version

01Approval is a record, not a memory. Eight items, written down, are what still work three months later.
02Every cost in this issue comes from a late decision. Colour, tolerance, packing — cheap to settle before the tool, expensive after.
03One date to put in the calendar now. Chinese New Year falls on 6 February 2027, and factory slots close well before it.

This issue is deliberately short. One checklist you can use this week, four new guides on decisions that get expensive when they slip, and two dates worth marking before the calendar fills.

01 New this fortnight four guides · 6 min
Ceramic mug sample approval The Sample Room: Why Approval Needs a Physical Record

What a sealed, dated reference protects you from, and why photographs never settle a quality argument.

Dimensional tolerance on fired ceramic Dimensional Tolerance on a Fired Mug

Which dimensions decide whether lids, stacking and carton counts still work, and how to write them down.

Ceramic mug weight classes Weight Classes: Why 350g and 280g Are Different Products

How weight, and the wall thickness behind it, sets perceived value, chip resistance and freight cost.

Approving ceramic colour from a proof Approving Colour From a Screen

Why a PDF and a fired mug never match, and the three decisions that end the debate before production.

02 Calendar watch three dates that move lead times
6 Feb 2027Chinese New Year Factories begin winding down in late JanuarySlots before the break are the first to close and the last to reopen. If your peak depends on pre-holiday production, the booking decision sits in the quiet month, not the busy one.
23–27 OctCanton Fair, Phase 2 Consumables and ceramics are in Phase 2A useful week to read the category even without a booth: breadth of shapes, surface finishes, and what competitors are showing. Spec negotiation still belongs after the fair, not on the floor.
Maythe Christmas window Sample approval needs to be finished by MayWorking backwards from a September shelf date: August at the distribution centre, June to July ex-works, so April and May are the last comfortable months to settle a design.
03 A question we were asked
Can you start with 1,000 pieces and scale later?

We do not produce below 5,000 pieces per design, and we do not run trial-scale batches. What we will do is hold your specification on file, tell you exactly what your first order needs to contain, and quote it properly when the volume is there.

The reason is not policy for its own sake. A short run occupies a full firing cycle: the same kiln time, the same handling, the same reject rate. Splitting it into a trial batch and a main batch does not reduce that cost. It pays it twice.

04 Supply note

Ceramic is fired in batches, so order timing matters more than order size. Production slots are booked earlier than most buyers expect, and the calendar tightens around Chinese New Year.

One term worth knowing

Vitrification

The point in firing where the body develops enough glass phase that open porosity drops sharply. It is what makes a mug resist staining, survive a dishwasher and hold its colour. Two mugs of identical shape can sit on different sides of that line, which is why water absorption is a specification number and not a marketing word.

05 One checklist before you approve a sample
✓Body and glaze named, not described
✓Rim diameter and ovality written with a tolerance
✓Weight recorded, with the measurement method
✓Decoration position stated: underglaze, in-glaze or on-glaze
✓Colour approved against a fired swatch, not a screen
✓Wash test result recorded on the actual decoration
✓Packing and carton configuration agreed in writing
✓A sealed retained sample held by the factory, with a date
06 From the factory

Our Liling partner lines are running Q4 at capacity. The buyer's column now covers six sections — sourcing, manufacturing, quality, packing, channels and how we work — and the index is updated every time a guide is published.
