What to Specify in a Handbag OEM Brief to Avoid Costly Revisions

What does an OEM handbag brief have to specify to avoid costly revisions? Five things make it quotable — silhouette with dimensions, quantity per colourway, material direction, branding position and a target retail price — and then eight detail blocks make it makeable: measurements at plus or minus 3 mm, material named by article and Pantone TCX reference, hardware given as an alloy with plating in microns, stitch density, branding measured from a datum edge, packaging, the inspection standard and the commercial terms. Every revision in this trade traces back to a line in the brief that was an adjective instead of a number, and the cost of an adjective is one full sampling round of 6-10 working days. A brief that fits on one page with those eight blocks produces a first sample that needs one numbered revision rather than three.

The brief in figures

Which Five Items Decide Whether a Brief Is Quotable?

A brief is quotable when it answers five questions, and every one of them has a number attached. A brief that answers four leaves the fifth to assumption, and an assumption inside a quotation shows up as either a wide range or a price that moves later. Neither is useful.

1. Silhouette and dimensions. Which shape, and what size in millimetres.
2. Quantity per colourway. A number per style and per shade, against a 500 pcs floor.
3. Material direction. Enough to price: article type, substance and finish.
4. Branding method and position. How the mark is applied and where, measured.
5. Target retail price or landed cost ceiling. The number the specification is engineered to.

The fifth is the one most often omitted, and it is the one that changes the quotation most. Without a ceiling, a specification is built to the best interpretation of the drawing, which is usually the most expensive one. With a ceiling, the same brief is engineered to a price — a different lining, a stock closure, a turned edge instead of a painted one — and the first sample lands in the band the brand can actually sell at.

What Does a Dimension Mean on a Tech Pack?

A dimension is a measurement with a datum and a tolerance. Those three words are the whole definition, and most briefs supply only the first. Body width of 32 cm is a measurement; body width of 320 mm measured across the base seam, plus or minus 3 mm, is a dimension.

• Body width and height in millimetres, measured from a stated seam or edge.
• Gusset depth at the base and at the top, because they are rarely the same on a tapered body.
• Strap drop measured from the top edge to the apex of the strap, not from the attachment point.
• Handle or strap width in millimetres, which sets both load and comfort.
• Tolerance of plus or minus 3 mm on every external measurement.

The strap drop definition is worth dwelling on because it is the single most common source of a first-sample revision. Measuring from the attachment point rather than from the top edge can differ by 20-40 mm on a shoulder bag, which is the difference between a bag that sits under the arm and one that swings at the hip. State the datum and the revision disappears.

How Is Material Specified Well Enough to Quote?

Leather is not a specification and neither is vegan leather. A material line good enough to price names four things: the article type, the substance, the temper or finish, and the colour reference. Anything less and the quotation is built on an assumption about the most expensive item on the bag.

Colour deserves one more line. A Pantone TCX reference is the starting point, not the finish: the acceptance standard is Delta E 2.0 or better against an approved physical swatch under a defined light source. Screens render colour differently, and a shade approved from a photograph is the cheapest way to get 500 units in the wrong colour.

What Does Hardware Need Beyond a Finish Name?

Gold hardware is a colour, not a specification, and the gap between the two is where most hardware revisions originate. Four fields make a hardware line quotable and testable, and all four belong in the brief rather than in a later email.

• Alloy and process. Zinc alloy die-cast, or a stock part from an existing catalogue.
• Plating thickness in microns. Typically 0.3-0.5 micron for decorative plating on zinc alloy.
• Corrosion benchmark. 24 hours to first corrosion under ASTM B117 is the usual requirement.
• Functional strength. A magnetic closure at 2-4 kg pull for a bag of this size; too strong and it tears out of a 1.2 mm panel.

One more field prevents a calendar problem rather than a quality one: whether the part is stock or custom. A stock closure carries no tooling; a custom cast part adds USD 900-2,600 and 15-25 days. Stating which is required in the brief means the tooling can be released with the deposit rather than after sample approval, which is the difference between a mould that runs in parallel and one that eats the bulk window.

How Are Stitching and Construction Specified?

Construction is where a brief that looks complete turns out to be silent, and silence defaults to whatever the line does normally. Four lines remove the ambiguity, and all four are what an inspector counts first at AQL 2.5.

1. Thread. Tex 40 bonded polyester, or the equivalent for the material being sewn.
2. Stitch density. 7-9 stitches per inch, which is the range that holds on leather without perforating it.
3. Seam allowance. 10 mm, stated rather than assumed, because it sets both strength and panel geometry.
4. Edge treatment. Painted, turned or raw — a decision that changes labour by 6-9 minutes per bag.

Two further lines belong here for any bag that carries weight: the reinforcement at the strap attachment and the base construction. A hidden webbing extension of 60-90 mm down the body panel, stitched in a box and cross pattern, is the standard answer to the most common field failure in the category. A base board of 1.2-1.6 mm between the outer base and the lining is the standard answer to a bag that will not stand.

How Are Branding and Packaging Measured?

Branding is specified by method, size and position, with position measured in millimetres from a datum edge. Packaging is specified as a list, and both belong in the brief rather than in a follow-up, because both have lead times that run alongside sampling.

Packaging then needs five items: a dust bag at USD 0.35-0.90, a hangtag at 55 x 90 mm, barcode symbology — EAN-13 for retail or the destination marketplace format — carton grade, typically five-ply corrugated, and a gross weight limit, commonly 18 kg. Where goods go to a marketplace fulfilment centre, its prep rules override the defaults and should be attached to the brief rather than discovered on dispatch day.

What Does the Brief Say About Quality?

One line does most of the work: pre-shipment inspection at AQL 2.5 under ISO 2859-1, with the written report issued to the buyer. That single sentence converts quality from an opinion into a threshold with an accept and a reject number attached, and it is the most valuable line in the commercial section.

• Inspection standard. AQL 2.5 under ISO 2859-1; third-party inspection by SGS available on request.
• Chemical compliance. REACH Annex XVII for the European market; Proposition 65 for California; CPSIA where a bag is marketed to children.
• Audit references. BSCI (amfori) or Sedex / SMETA for the facility, where a retail buyer requires them.
• Material traceability. Leather Working Group tannery chain, or GRS documentation for recycled fibre claims.
• Tolerance statement. Plus or minus 3 mm on external dimensions, and Delta E 2.0 or better on colour.

Ask for these documents at brief stage rather than at inspection. A test report that arrives after the cartons are packed cannot change anything, and a compliance request made late is one of the few things that can delay a shipment that was otherwise ready.

What Should Not Be in the Brief

Completeness is not the same as length, and four things actively make a brief worse. Each of them adds words without adding a decision, and each of them slows the technical review that has to read it.

• Adjectives where numbers belong. Comfortable, premium, soft and elegant cannot be quoted. Each one generates a question, and each question costs a day of the review rather than an hour.
• A mood board in place of a drawing. Inspiration is useful context and useless instruction; attach it separately, below the dimensioned drawing, never instead of it.
• Internal construction detail on the first pass. Pocket count and lining weight belong; the full reinforcement schedule and interlining map can follow at revision one without affecting the sampling window.
• An unrealistic launch date. A date that ignores the 35-50 day production 35-50 days of transit produces a slot nobody can book, and it is better replaced by a required dispatch window with the honest constraint noted.

One more exclusion is worth naming because it costs money rather than time: do not specify custom hardware on a first brief unless the brand is prepared for USD 900-2,600 and 15-25 days. A stock closure with a branded plate achieves most of the recognition and leaves the budget free for the material, which is the line the customer actually judges.

What Goes in the Commercial Section?

The commercial section is short and it is the part that decides whether the quotation can be planned against. Seven lines, each with a number.

1. Quantity per style and per colourway, against a floor of 500 pcs each.
2. Target retail price or landed cost ceiling per SKU.
3. Trade term. FOB Xiamen, with CIF and DDP available on request.
4. Payment term. T/T, with the deposit and balance split stated.
5. Required dispatch window, as a week or a month rather than a launch date.
6. Destination market, which sets the compliance set.
7. Packaging prep rules if goods go to a fulfilment centre.

With those seven and the eight detail blocks above, a brief fits on one page and produces a quotation that can be planned against, a sample in 6-10 working days and — most of the time — a single numbered revision round. Programmes coordinated through our validated partner factory Quanzhou Yingming Bags run on that basis across 7 production lines with export experience since 2014, bulk at 35-50 days and inspection at AQL 2.5. The nine-stage workflow shows what happens to the brief next, the MOQ expectations explain the quantity floor, and the quality control checks detail what the inspection counts. The OEM services page sets the full frame.

The Revision Number Is the Cheapest Control in the Brief

Most costly revisions are not design changes, they are version errors. The sample on the table is unit R2, the drawing in the sample room is R1, and the comment list was written against the R1 photographs. Three documents, three versions, one avoidable round. The control is a single habit: every drawing, sample and comment list carries the same revision code, and no review opens until all three match.

• Number every round. R1, R2, R3, stamped on the drawing and recorded on the physical unit.
• Write comments as numbered items tied to a dimension. An item reading strap drop 260 mm, currently 232 is a revision; a note reading strap feels short is a conversation.
• Seal the approved unit and photograph it front, side and interior before it leaves the bench.
• Keep a retain sample per revision, so a later dispute is settled against a physical object rather than an email.

An Acceptance Table Turns the Brief Into a Test

A specification without acceptance numbers is a description. One table gives every measurable line a nominal, a tolerance and a method, and that table is what the pre-shipment inspection works from. It is also what ends arguments: a unit at 234 mm against a nominal of 230 mm plus or minus 3 mm passes, and there is nothing left to negotiate at the inspection table.

How Many Samples to Ask For, and What Each One Proves

A first programme usually needs three units and one photograph, and naming them at brief stage avoids the round in which everybody discovers they were expecting something different. Each unit answers a different question, and confusing them is expensive: a salesman sample is not a construction reference, and a pre-production unit is not a photography unit.

1. First sample. Confirms the pattern and the proportion in three dimensions; built in the confirmed material, 6-10 working days.
2. Revised sample. Answers the numbered revision list; 3-6 days for a standard construction, longer for a framed or stacked build.
3. Pre-production unit. Built on the bulk line with bulk materials and bulk settings. This is the unit inspection compares against.
4. Shipment sample. One unit pulled from the finished lot and held with the inspection report.

The Attachments That Make a Brief Complete

The brief itself should stay on one page, and everything that does not fit belongs in an attachment named on that page. Five attachments cover a first programme, and each one removes a class of follow-up question. Naming them on the brief also fixes the version, because an attachment carries a date and a revision code while a description inside an email does not.

• A bill of materials listing every component by article, substance and colour reference, with the stock code where known.
• Vector artwork for the mark, with the branding panel dimensions marked on the dimensioned drawing.
• A packing specification: dust bag, hangtag, polybag thickness, carton grade, count per carton and gross weight limit.
• The compliance set for the destination market. The programme document set lists what a retail buyer asks for and in what order.
