Waterproof Bag Contract Manufacturing: Clause by Clause

What a Manufacturing Agreement Is Actually For

A manufacturing agreement is not a promise that the bags will be good. Good bags come from the specification and the process. The agreement's job is to decide, before anything goes wrong, who bears which risk. Every disagreement that later becomes expensive is one of a small number of predictable events: a material is unavailable, a price moves, a shipment fails inspection, a tool is wanted by someone else, or the relationship ends.

That framing matters because most agreements in this category are either too thin or too thick. A thin agreement is a purchase order with a signature line, and it resolves nothing, so every dispute becomes a commercial negotiation conducted while the goods sit at origin. A thick agreement copied from another industry addresses risks that do not exist here and leaves the nine that do exist untouched.

The right length for a bag programme is a short master agreement with a specification schedule attached. The master covers the nine risks and stays in force across orders. The schedule carries the product-specific numbers: shell, gauge, hardware, colourway references, dimensions, decoration, acceptance test, packing and carton specification. Amending a schedule is fast; amending a master agreement rarely is.

Scope and Specification: The Schedule That Controls

The specification schedule is the most important document in the relationship and the one most often treated as an attachment. It should name the shell material and its gauge or coating weight, the hydrostatic head the shell must reach, the hardware with its finish and rating, the webbing and trim references, the colourway references, the dimensions with tolerances, the decoration method and placement, and the packing specification.

Tolerances deserve particular attention because they are where disagreement concentrates. A dimension without a tolerance is not a dimension, and a colour without a tolerance is not a colour. On sewn and welded soft goods, dimensional tolerance is typically expressed as a percentage or a millimetre band, and colour as a grey scale grade against an approved swatch. Both need a number, and the number needs to be reachable on the line.

The schedule should also say what happens when a named material is unavailable. The clause we prefer requires written notice before substitution, a qualification of the substitute including a weld trial and an ingress re-test, and the buyer's written acceptance. Without it, a substitution is discovered at inspection, by which point the whole lot has been cut and welded from a material nobody approved. One more item belongs in the schedule rather than in an email: the pre-production sample as a contractual reference. The agreement should state that the approved sample, signed and dated, is the reference for hand feel, shade, weld appearance and finish, and that two copies are retained, one by each party. Written specifications resolve measurable questions well and sensory ones badly, and the retained sample is what settles the sensory half.

Price Adjustment Clauses for Resin and Film

Coated fabric and TPU film are petrochemical derivatives and their input costs move. A fixed price for a twelve month programme is either a price the supplier has padded to cover the risk, or a price the supplier will later ask to renegotiate. Both outcomes are worse than an honest adjustment clause, which is why we propose one rather than waiting to be asked.

A workable clause has four parts. A named index or a defined trigger, usually a movement beyond a stated percentage in the input cost. A threshold, so that ordinary movement is absorbed and only material movement triggers a review. A mechanism, typically a written notice with supporting evidence and a negotiation period. And a cap, so that the adjustment cannot be unlimited in either direction.

What a price clause should not do is reopen the whole quotation. It should adjust the material component and leave labour, overhead and the supplier's margin alone. A clause that permits a general re-quotation on any cost movement is not a price adjustment clause, it is an option to renegotiate, and it will be exercised at the least convenient moment for the buyer.

Tooling Ownership, Maintenance and Return Terms

Tooling is the clause that most often decides whether a successful programme stays with the brand. A cutting die, a weld electrode, a closure jig and a custom hardware mould are all paid for by somebody. The default in the trade is that the supplier holds them, which is defensible when the supplier paid for them and indefensible when the brand did.

The clause should therefore state three things. Who owns each tool, usually the brand where it paid and the supplier where it did. Who maintains it and who pays for refurbishment after a period of disuse, because a die that has sat for two years needs work before it runs again. And what happens on exit, specifically whether the brand may take delivery of its tools or have them transferred to another producer.

There is a second, quieter risk inside this clause: shared tooling. If a brand pays for an electrode that also runs another buyer's product, the brand has paid for capacity it does not control. The clause should state whether tools cut for the programme may be used for any other programme, and exclusivity of use is worth asking for even where exclusivity of product is not. The practical companion to the ownership clause is a tooling register. Every die, electrode, jig and mould cut for the programme is listed with its date, its cost, the party that paid, its location and its last maintenance date. The register takes an hour to produce and it is the document that makes the ownership clause operable on exit, because a brand that cannot list its tools cannot ask for them to be returned, and a supplier asked for an unlisted tool will reasonably say it has none.

Intellectual Property and the Nesting Drawing

In bag manufacturing the protectable asset is rarely the idea and usually the drawing. A concept is not protectable. A dimensioned drawing with a panel nest, a seam map and weld parameters is a technical document, and it is what a brand should own at the end of an OEM development. Brands that pay for development and never receive the drawing have bought an expensive version of a shared product.

The sequence that works is NDA first, drawing second, sample third, tooling clause before any die is cut. That order is not ceremonial. Once a sample exists, the design has been disclosed; once a die is cut, the leverage has shifted. An NDA signed after the sample round protects a disclosure that has already been made, which is the most common timing error we see in private label programmes.

One practical addition costs nothing and resolves most later disputes: revision control. Every exchanged file should carry a revision letter and a date, and every sample should carry the matching revision on its tag. When a question arises about which version was approved, the revision trail answers it in a way that a signed document alone cannot, because it establishes sequence as well as content.

Exclusivity, Territory and Channel Terms

Exclusivity is a commercial term rather than a technical one, and it has to be bought. On a shared shell the product is exclusive only if the agreement says so, and it is usually granted in exchange for a volume commitment, a defined period, or both. On a full OEM build the product is exclusive by construction because nobody else holds the drawing, but the agreement should still say so.

Territory and channel are the two dimensions buyers forget. A supplier can honour product exclusivity and still sell the same shell into a different country or through a different channel, which for a brand building a position in one market may be entirely acceptable and for a brand selling globally is not. Naming the territory and the channel is what makes the term meaningful.

The clause should also state the consequence of breach, because an exclusivity term without a remedy is a statement of intent. The remedies that work in practice are a defined period of exclusive supply as compensation, a refund of development or tooling charges, or a right to terminate without penalty. Any of the three is better than a general damages reference that nobody will litigate.

Quality Clauses That Make AQL 2.5 Enforceable

Naming AQL 2.5 under ISO 2859-1 is necessary and not sufficient, because the standard sets the sampling plan and not the definitions. The clause has to add the defect classification: critical for anything breaching the waterproof claim or creating a safety issue, major for anything affecting saleability, minor for finish variation within tolerance. Without those three definitions, every finding is arguable.

The second addition is the acceptance test, written with its method, its duration and its pass mark. Spray behaviour under AATCC 22, rain behaviour under AATCC 35, immersion under IEC 60529 and shell resistance under ISO 811 are all verifiable, and the purchase order should name which applies and what the pass mark is. This converts the waterproof claim from a marketing statement into an inspection criterion.

The third addition is the consequence of a fail. Rework and re-present, sort at an agreed cost allocation, or reject and remake. Naming the outcome at signing removes the negotiation at the moment when the goods are already made and the calendar is already under pressure, which is exactly when a supplier's and a buyer's interests diverge most sharply.

Defect Liability and the Claim Window After Arrival

Inspection at origin settles visible defects. It cannot settle latent ones, which on a waterproof bag means a weld that holds at the factory and fails after weeks of use, or a coating that degrades in a hot container. The agreement needs a claim window that starts at arrival rather than at shipment, and it needs a defined period, typically measured in weeks or months, during which a latent defect claim can be raised.

The clause should also define what the buyer has to show. The workable standard is photographs, a sample of the defective units, the quantity affected and the lot reference from the carton label. Without the lot reference the claim cannot be traced back to a material lot or a shift, and without traceability the conversation becomes a general complaint rather than a specific one.

Remedy is the last piece. Replacement of the affected quantity on the next order, credit against the balance, or remake at a defined cost allocation are the three that work. What does not work is an open-ended indemnity for consequential loss, which most suppliers will not sign and which, if signed, will be tested at exactly the moment the relationship is least able to bear it. A claim pack that arrives complete is settled in days rather than weeks, so the agreement should list what it contains. Carton lot label photographs, the purchase order reference, the quantity affected by defect type, between three and five representative defective units, and photographs showing the defect in context rather than in close-up alone. A claim supported by that pack is a technical conversation about a lot; one without it is a commercial conversation about trust.

Payment Terms, Title and Risk Transfer

Standard terms on waterproof bag programmes are T/T 30 per cent deposit and 70 per cent before shipment, with shipment FOB Xiamen. The clause should say more than the percentages: it should state that the deposit triggers material booking, that the balance is due before release, and what happens if the balance is late, since storage at origin is a real cost and a real risk.

Title and risk are separate concepts and are worth stating separately. Under FOB terms risk transfers when the goods are loaded on board the vessel the buyer nominates. Title can transfer at a different point, and where the buyer has paid in full before shipment it is reasonable for title to pass at payment rather than at loading. Stating both removes an awkward question if goods are damaged between the two events.

The clause buyers forget is the one about the vessel nomination. Under FOB the buyer nominates the forwarder and the vessel, and if the nomination arrives late the goods wait. A clause requiring the buyer to nominate within a defined number of days of notice of readiness, with storage and any demurrage allocated accordingly, is standard in most trades and often missing here.

Force Majeure and Capacity Allocation Clauses

Force majeure clauses in this trade are usually copied from a template and list events that are irrelevant while omitting the ones that actually occur. The events that disrupt bag programmes are raw material allocation, energy curtailment affecting extrusion or coating, port closure, and vessel space shortage. Naming those four is more useful than naming war and flood.

The allocation question is the one that actually decides outcomes. When capacity is short, who gets the line? A clause that says the supplier will use reasonable endeavours resolves nothing. A clause that states the buyer's ordered quantity is booked against a line and that booked orders rank ahead of unbooked ones is specific, testable, and the thing a buyer actually needs in a peak season.

Duration and exit from the event matter as much as the trigger. A force majeure clause with no time limit allows an indefinite suspension with no remedy for the buyer. The version we propose requires notice, a cure plan, and a right for the buyer to cancel the affected quantity without penalty if the event continues beyond a stated number of days.

Confidentiality and the Subcontractor Question

Confidentiality in this trade protects three things: drawings and technical files, artwork and brand assets, and commercial terms. It does not protect construction, because a construction is generally not protectable and can usually be reproduced by anyone who buys the bag. Buyers who believe an NDA prevents a bag being copied are usually disappointed, and the disappointment is avoidable if the scope is stated honestly at the start.

The subcontractor question is the one that should be in the agreement and usually is not. Printing, plating, moulding and some specialised welding are commonly placed outside the main facility. That is normal and not a problem in itself. What matters is whether the buyer is told, whether the subcontractor is named, and whether the supplier remains fully responsible for the subcontracted work.

The clause we recommend is short: subcontracting permitted for defined processes, with a named list maintained and available on request, and the supplier remains responsible for the finished product as if it had performed the work itself. That gives the buyer visibility and gives the supplier the flexibility the process needs, without pretending that everything happens under one roof.

Termination, Transition and the Return of Assets

Exit terms are the least negotiated and most valuable clauses in the agreement, because they are the only ones that operate when the relationship has already broken down. Two rights matter: the right to terminate for cause with notice and a cure period, and the right to terminate for convenience with a defined notice and settlement of work in progress.

Transition is where value is either preserved or lost. On exit the buyer needs the drawings, the tooling it owns, the material specifications, the approved swatches and the test reports. Without a clause requiring their return, the buyer has to rebuild the product from a physical sample, which is possible but slow, and the programme loses a season.

Work in progress needs a rule as well. At any point in a 35 to 50 day run there is cut material, part-assembled goods and finished stock, and each has been paid for or not depending on where the deposit and balance sit. A clause stating how work in progress is valued and settled on termination prevents the exit argument from being about money rather than about product.

A Clause Checklist to Read Before You Sign

Nine clauses cover the nine risks in a waterproof bag programme. The list below is what we suggest a buyer's counsel check before signature, in the order the risks tend to materialise. Most agreements we see fail on the fourth, fifth, eighth and twelfth items, which correspond to tooling, intellectual property, latent defects and exit.

Our own position on these clauses is straightforward. We hold BSCI social compliance audit coverage and ISO 9001:2015 certification, we produce in a validated production partner facility of 4,950 square metres with 7 lines, 149 machines and 137 people verified by SGS at 200,000 pieces a month, and we sign agreements that state tooling ownership, acceptance criteria and transition terms because a programme that cannot be moved is a programme nobody should start.

Frequently Asked Questions

Q1: What should a waterproof bag manufacturing contract cover?

A: Nine risks: specification drift, material substitution, price volatility, tooling ownership, design ownership, channel conflict, inspection disagreement, latent defects and exit. A short master agreement covering those, with a product-specific specification schedule attached, works better than either a bare purchase order or a template copied from another industry.

Q2: Who owns the tooling on a waterproof bag programme?

A: The party that paid for it, and that should be written down rather than assumed. The clause should also cover maintenance, who pays for refurbishment after a period of disuse, whether tools cut for the programme may be used for any other programme, and whether the brand may take delivery of its tools on exit.

Q3: Is naming AQL 2.5 enough in a quality clause?

A: No. ISO 2859-1 sets the sampling plan but not the definitions, so the clause must add the defect classification, the acceptance test with its method, duration and pass mark, and the consequence of a fail. Without those three additions every inspection finding becomes a negotiation rather than a measurement.

Q4: How should price volatility in film and resin be handled?

A: With a defined adjustment clause rather than a fixed price that will later be renegotiated. A workable clause names a trigger and threshold, limits the adjustment to the material component rather than a general re-quote, sets a negotiation period with evidence, and caps the movement in both directions.

Q5: Does an NDA stop a bag design from being copied?

A: Not usually. Construction is generally not protectable, and what an NDA protects is drawings, artwork, brand assets and commercial terms. The valuable asset is the dimensioned drawing with its panel nest, seam map and weld parameters, so the brand should require delivery of the drawing and hold it under revision control.

Q6: What is a reasonable defect claim window after arrival?

A: A defined period starting at arrival rather than at shipment, since inspection at origin cannot detect latent weld or coating failures. The clause should also state the evidence required, which is photographs, samples, the affected quantity and the carton lot reference, plus the remedy, which is replacement, credit or remake.

Q7: What does FOB Xiamen mean for title and risk?

A: Risk transfers when the goods are loaded on board the vessel the buyer nominates, while title can pass at a different point and commonly passes at full payment. The agreement should state both, and should also require the buyer to nominate the vessel within a defined period, with storage allocated if the nomination is late.

Q8: Should subcontracting be permitted?

A: Yes, for defined processes such as printing, plating and specialised welding, but with three conditions: the buyer is told, the subcontractor list is available on request, and the supplier remains fully responsible for the finished product. Pretending that everything happens under one roof helps nobody and is rarely true.

Q9: What should happen to drawings and tooling on termination?

A: The buyer should get the drawings it owns, the tooling it paid for, the material specifications, the approved swatches and the test reports. Without a transition clause the product has to be rebuilt from a physical sample, which is possible but costs a season, so transition terms are among the most valuable clauses in the agreement.

Q10: How is exclusivity granted on a shared shell?

A: Contractually, and usually in exchange for a volume commitment or a defined period. A shared shell is shared by construction, so exclusivity is a commercial term rather than a technical one. The clause should name the territory and the channel as well as the product, and should state the consequence of breach.

Q11: What is the MOQ written into a manufacturing agreement?

A: 500 pieces per style per colour. The agreement should state it because colourways count separately, so three colourways of one style is three lots. The figure is unchanged by tooling ownership, exclusivity or any other clause, because what the minimum covers is the material lot, the line change and the set-up.

Q12: What production capacity stands behind the agreement?

A: A validated production partner facility of 4,950 square metres with 7 lines, 149 machines and 137 people, verified by SGS, at 200,000 pieces a month, holding BSCI social compliance audit coverage and ISO 9001:2015 certification. Bulk production runs 35 to 50 days from the approved pre-production sample, with sampling at 6 to 10 working days.
