A tooling or screen charge pays for the one-off work of producing a physical tool — a mould cavity, a steel-rule cutting die, a pad-print plate, a heated embossing die or a tensioned mesh — together with the programming and trial shots needed before that tool can run. Indicative one-off figures sit at USD 300-2,500 per tool, while the separate sampling fee of USD 50-150 returns to the buyer as a credit when an order follows. Volume starts at a minimum of 500 units per reference, a first article is finished in 6-10 working days, extending to 12-15 on a demanding construction, and a production order then occupies 35-50 days. The boundary is that all sums here are indicative and quoted on FOB Xiamen terms for civilian load-carriage goods — hiking, commuting, worksite tools and first aid — and nothing on this page is legal advice.

What a Tooling Charge Pays For: Three Buckets Behind One Line

A tooling charge is raised once, before any physical work begins, and it buys three separate things that are easy to confuse because they arrive on a single line. The first bucket is preparation: artwork is redrawn for the process that will actually make it, a cutting path or electrode path is programmed, and a first-off trial is booked on a machine. The second is the tool: hardened steel, aluminium, silicone rubber, brass or tensioned mesh, chosen by the route. The third is correction, because a first shot almost never matches the drawing.

Preparation is where most underestimates happen. A mark drawn for print carries hairlines and soft gradients that a silicone mould or a steel rule die simply cannot hold; converting it means redrawing, and redrawing is paid labour. An embroidered mark needs a digitised stitch file rather than a drawing, and that file has to be rebuilt when the size moves appreciably, because stitch direction, underlay and density are all size-dependent.

The tool itself is priced by material, cavity count and expected service life. A single-cavity aluminium die for a small decorative part sits near the lower end of the indicative USD 300-2,500 band. A multi-cavity hardened tool for a load-bearing metal component sits near the top, because machining hours, heat treatment, electrode work and ejection hardware all scale together. Buyers rarely see that split, which is precisely why the next point matters.

Correction is the bucket most often left out of a quotation and then argued about months later. A tool leaves the machine, produces a first shot, and the shot is judged against the drawing for flash, sink, short fill, registration drift and emboss depth. Each correction consumes machine time and setter time, so it belongs on the same line as the tool instead of being absorbed silently and reappearing as a change request.

Two habits keep this predictable. Ask for the figure split three ways before approving it, and approve it against a drawing revision number rather than against a logo file, because a revision change re-opens all three buckets at once.

Spec rule: Request every tooling quotation split into preparation, tool material with cavity count, and first-off correction, since those are the only three places the price can move and a lump figure hides all of them.

Pad Print, Heat Press and Die Casting Compared by Entry Threshold

Three routes turn up in nearly every bag programme and they sit at very different entry points, because the physics behind each one is different. Pad printing moves ink from an etched plate through a silicone pad onto a part, so the tool is a shallow etched plate plus a pad profiled to the part. Heat pressing — embossing, debossing or applying a transfer — uses a heated die machined to the artwork and suits flat or gently curved panels. Die casting forces molten zinc alloy into a machined cavity to make a metal part such as a puller, a badge or a buckle component.

The thresholds differ for one dominant reason: how much metal must be removed and to what tolerance. An etched plate is shallow and quick to produce. A heated die can be cut from aluminium for short runs or from brass or steel for long ones, and that material decision alone sets a large part of the price. A die-cast cavity must survive repeated thermal and mechanical shock, so it is cut from hardened steel with cooling and ejection provisions, which places it at the upper end of the indicative USD 300-2,500 range.

Revision exposure is the row worth reading twice. A route with a low entry price is not automatically the cheap one across a programme, because a plate that must be re-etched every time the artwork moves will cost more over three revisions than a die that simply gets re-cut once.

Load is the second filter. A decorative mark on a flat panel has no structural duty, so route choice can follow price and appearance. A mark on a component that carries strap tension has a duty, and the process that makes the component is decided by the component, not by the logo — which is why a metal puller is cast first and decorated second.

Bottom line: Select the route by part geometry and by whether the part carries load — flat decoration to a heated die, small curved parts to a pad plate, load-bearing metal to a cast cavity — because entry price follows the machining, never the artwork.

Screen and Mesh Charges: Where Colour Count Becomes Money

Screen charges scale with colour count for a blunt reason: every colour in a design needs its own mesh, its own registration step and its own pass over the panel. A single-colour mark needs one screen; a four-colour mark on the same panel needs four, and the tolerance between those passes stops being an assumption and becomes a specification line that has to be written down and checked.

Mesh count is the second lever. Fine detail and halftones need a higher mesh count, and higher-count mesh is both more expensive to buy and shorter in service, because the openings clog sooner and the tension falls faster under cleaning. Where a design can be simplified without losing the brand mark, simplifying it usually saves money on every repeat of the programme rather than once.

Durability of the finished mark is a separate question from making it, and it is where programmes get caught. Rubbing fastness of a printed or transferred mark is assessed by the method published as AATCC 8, and laundering durability is assessed on its own route; a mark that leaves the panel in the first wash is a specification failure, not a printing failure, because the ink system was never qualified against that base cloth.

Put the qualification before the tooling decision. Approving a print system on the actual shell fabric costs a test slot and a short delay; discovering the failure after 500 pieces are cut costs the cloth, the screens and the bulk window.

Takeaway: Budget one mesh per colour per placement, write the registration tolerance into the artwork specification, and qualify the ink against the production cloth before the first screen is exposed rather than after the bulk run is cut.

Why One Logo Carries Three Different Prices on One Bag

The same mark placed on four different parts of one product can produce four different quotations, and the variation is not arbitrary. Placement decides substrate, substrate decides process, and process decides tooling. A woven label carries the mark on a loom with no hard tool at all. The same mark as a silicone badge needs a mould. As a heat transfer it needs a plate and a jig. As an etched metal plate on a front pocket it needs a die-cast cavity and a fixing method.

Curvature is the quietest driver. A pad-print pad has to be profiled to the surface it touches, so a flat panel and a radiused corner on the same shell need different pads even when the artwork is identical. Embossing behaves the same way: a die cut for a flat panel will not press cleanly across a seam roll or a piped edge, and forcing it produces a mark with uneven depth that no amount of pressure adjustment will fix.

Size is the third driver, and it interacts with process rather than adding linearly. An embroidered mark below a modest height loses legibility because stitch width is fixed by thread, so a small logo that reads perfectly at 60 mm can become a blob at a fraction of that. A silicone badge keeps legibility at small sizes because the cavity is machined, which is exactly why small marks migrate to moulded routes as they shrink.

The practical discipline is to decide placement before quoting artwork, not after. A decorative schedule that lists every mark with its part, size, substrate and process lets a tooling quotation be produced in one pass against the drawing revision, and it stops the slow drip of add-on tools that appears when placement is settled on the production line instead.

Verdict: Fix the decoration schedule — part, size, substrate and process for every mark — at drawing revision stage, because placement changes made after tooling starts convert a one-off charge into a repeat charge.

Refundable, Deductible or Forfeit: How the Money Is Settled

Two different sums sit on the same early invoice and are settled in opposite ways, which is the origin of most arguments. The sampling fee is a charge for making one piece outside a production run; it is quoted at USD 50-150 per reference and comes back to the buyer as credit when an order follows. Tooling is not that. It buys a durable asset that stays on the floor after the sample is shipped, so it is normally treated as capital rather than as a deposit.

Three settlement models appear in quotations. The first hands the money back in cash the moment the order clears the agreed floor. The second knocks the amount off the bulk invoice, and that is the commoner route since no separate transfer is needed. The third keeps the money where no order follows or where the order lands under the floor that triggers it.

Tooling is handled differently again. It can be billed outright and owned by the buyer, billed and held by the production side for exclusive use, or amortised into unit price across an agreed quantity. Each model is defensible; what causes trouble is a quotation that says refundable without saying which of the two sums the word applies to, or what quantity triggers it.

Payment sequence matters to the credit model. With T/T 30/70 terms the 30% deposit releases the material purchase and the 70% balance settles before shipment, so the credit has to sit on the balance. Placing it against the deposit instead would leave the material booking short of the sum it was sized to fund.

Write the trigger as a number and a condition, not as an intention: credit applied at 500 pieces or above, against the balance payment, on the first bulk order for that reference, within a stated period from sample approval.

Judgement: Separate the two sums on the purchase document — sampling fee refundable against the balance at 500 pieces, tooling billed as a capital item — and name the trigger quantity explicitly, because one word applied to both is what later becomes a dispute.

Who Owns the Tool, and What Happens When a Programme Moves

Ownership clauses are short, rarely negotiated, and expensive when they are finally read. The default in most programmes is that the production side holds the tool and uses it exclusively for the brand that paid for it. That arrangement is workable, but it needs three supporting sentences: how long the tool is kept after the last order, what notice precedes disposal, and what the brand pays to have it released or duplicated.

Dormancy is the practical risk. A tool left unused for several seasons can be lost, reassigned, or scrapped during a floor reorganisation, and the brand then pays the full one-off figure again inside the USD 300-2,500 band to restart. A clause that requires written notice before disposal, and that lets the brand buy the tool out or pay for storage, converts a surprise into a line item.

Exclusivity is narrower than it sounds. It covers the cavity and the die, not the intellectual property in the mark; a brand that wants protection on the artwork itself needs its own registration in the destination market, which no tooling clause provides.

Selection rule: Accept held-and-exclusive only when the clause also fixes a retention term, a disposal-notice duty and a release price, because ownership without those three leaves the brand paying the full one-off band again after a dormant season.

How Tooling Work Fits the Sampling and Bulk Calendar

Tooling is the one workstream that can delay everything behind it, because nothing physical exists until the tool does. A quotation comes back inside 24-48 hours, but that figure covers pricing, not tool making. Machining, etching, heat treatment and first shots all sit between the approved drawing and the first usable part, and they run whether or not the rest of the programme is ready.

Sequencing it correctly is mostly a matter of ordering. Artwork is locked first, the decoration schedule follows, tooling is released against a drawing revision, and only then does the prototype build start its 6-10 working days — extended to 12-15 where the construction is demanding. Releasing tooling before the artwork is frozen produces a tool that matches a drawing nobody is building to any more.

Bulk follows the same logic at larger scale. Volume needs 35-50 days from a 500-piece floor, and a missing tool stops the line at the point where material has already been cut and booked. Release at the end is by attribute sampling at AQL 2.5 — Critical 0, Major 2.5, Minor 4.0 — under a plan taken from ISO 2859-1 at inspection level II, and goods are sold on FOB Xiamen terms with T/T 30/70 payment. Onward carriage then needs 25-35 days by sea, 5-8 days if flown and 3-5 days on a courier.

One correction saves more time than any expediting: book the tool slot at the same moment the drawing revision is issued, not at the moment the sample is ordered, because the machining queue is the longest fixed interval in the whole calendar.

Gates, Records and the Production Facts Behind the Figures

Our production team runs tooling and decoration work from a floor of 4,950 m² verified by SGS, where 137 staff operate 149 machines set across 7 production lines and monthly output stands at 200,000 units. The founder has been in bag production since 2004 and the company dates from 2014. Pricing is issued within 24-48 hours. A first article is turned round in 6-10 working days, lengthening to 12-15 on an involved construction, and the volume order then occupies 35-50 days at a minimum of 500 units per reference. Clearance runs on an attribute acceptance plan at AQL 2.5 with zero tolerance for critical defects, 2.5 for major and 4.0 for minor, taken from ISO 2859-1 at general level II; sale is on FOB Xiamen terms with T/T 30/70 payment; onward carriage is 25-35 days by sea, 5-8 days if flown and 3-5 days on a courier.

The documentation set for one tool should carry five items: the drawing revision it was made to, the quotation split three ways, the first-off trial record with measurements, the artwork file reference including colour call-outs, and the ownership clause with its retention term. Five files, one folder per tool, and the folder travels with the reference if the programme moves.

Re-qualification is event-driven rather than calendar-driven. Re-run the first-off trial after any change to artwork scale, substrate, cavity count or part supplier, and re-check rubbing fastness to AATCC 8 whenever the ink system or the cloth changes. A tool that has been re-cut is a new tool for evidence purposes, even when the part number has not moved.

Tooling decisions connect directly to the wider build: a custom modular backpack programme aligns tool release with the decoration schedule, a MOLLE attachment grid fixes where hardware tooling is needed, and the whole sequence is booked through the sampling and tooling desk. Questions about a specific quotation belong at the enquiry desk with the drawing attached.

Keeping five records per tool — drawing revision, split quotation, trial measurements, artwork reference and ownership clause — and re-running the trial on every artwork or substrate change keeps the tooling evidence usable for the life of the reference.
