Your first leather order: what it costs and what to send

Every guide to launching a footwear brand tells you to find a good supplier. None of them tells you what to put in the email, what number the tannery is waiting for, or what the order ties up in cash.

A guide by TL San Martín, a tannery of origin in Elda (Alicante, Spain) since 1995, LWG Gold certified under the Leather Manufacturer standard.

This is the first order in numbers, from the tannery's side of the table: what you send, what it costs and what gets locked.

What does a tannery need before it can quote?

Six fields. Copy them into the email.

Three words you will meet in the reply and probably have not met before. Crust is leather that has been tanned and dried but not yet dyed to your colour or finished — it is the stock a tannery holds so it can make your colour quickly. A square foot is the industry's billing unit, marked on the back of every hide by a measuring machine. A side is half a hide, split down the spine, and is how upper leather is usually shipped.

How big does the first order actually have to be?

Published minimums are all over the map, and almost all of them come from distributors rather than tanneries:

That last row is not a promotion, it is a structural fact worth understanding: a footwear brand reorders. The tannery's interest is in getting your specification right at 20 m², not in selling you 400 m² of a colour you will abandon after the first production run. What we do insist on is a physical sample before the first order, because temper and hand cannot be judged from a screen.

The number that matters to you is not the minimum anyway. It is how much leather your first run consumes — roughly 0.14–0.16 m² (1.5–1.7 sq ft) of net upper per pair of a men's derby before waste, which at 70 % utilisation means about 0.20–0.23 m² purchased per pair. Two hundred pairs is therefore 40–46 m², not a truckload. Work it through properly in how much leather for shoes and the Spanish cuántas pieles necesito.

Why does colour, not quantity, set your real minimum?

Because leather is dyed in a drum, and a drum has a floor. A stock colour that the tannery already runs has no practical minimum — you are buying from a batch that exists. A bespoke colour does: the drum has to be loaded to a working level, so the real minimum on a custom shade is the size of one dye lot, typically counted in hundreds of square metres, not tens.

The consequence for a first order is blunt: take a stock colour for the launch, develop your bespoke shade for season two. Brands that insist on a signature colour in month one pay for it twice — once in the minimum, and once in the reorder, because a colour developed against 20 m² of sampling will not repeat identically at volume.

Expect the tannery to talk about batch or dye lot. Two hides from different batches of the same article and the same colour code will not match perfectly under shop lighting. If a pair of shoes uses leather from two batches, you will see it. The control for this is in sample to bulk consistency.

What is a lab dip, and which reference wins?

A lab dip is a small trial piece dyed to your target so you can approve the colour before production. The tannery sends it, you approve it in writing, and it becomes the standard.

The rule almost nobody writes down: keep two references, and say which one governs.

1. The approved lab dip — the colour you signed off.
2. The production reference — a swatch cut from the actual delivered batch.

They will diverge slightly. When they do, the factory cutting your uppers needs to know which one it is matching, because otherwise it will guess, and it will guess differently in each production run. Put one sentence in the order confirmation: "The signed lab dip of [date] governs; the production reference is informational." Or the reverse, if you prefer to match the delivered goods. Either is defensible. Having neither is what causes the second-season colour argument.

Sign the swatch card physically, date it, and keep a copy at the factory and a copy with you. A photograph of a swatch is not a reference.

What does the first order tie up in cash?

Take a 200-pair launch at 0.22 m² purchased per pair: 44 m². At €18–28/m² for a decent chrome-tanned calf, that is €790–€1,230 in upper leather, plus lining. Against a shoe that retails at €180, the upper leather is roughly 3–4 % of retail — far less than founders expect, and far less than the tooling.

The real cash risk is not the price per metre, it is ordering the wrong substance or the wrong colour and having it sit. Leather does not expire, but a colour you have moved on from is dead stock. Price per unit is covered in leather price per square foot; who you are actually buying from — a tannery or a middleman — in tannery vs leather distributor.

Post your first-order spec under Materials (article type, substance, colour direction, quantity in m², date) and the tanneries and stockists reading the board can answer directly. Looking for a factory rather than a material? Post under Partners & factories. Post on the open board.
