What Happens After You Contact Us

Most buyers want to know not just whether we will reply, but what the next four weeks look like. The sequence below is the standard path from first message to shipped goods, with the deliverable you receive and the decision you own at each step.

Two things compress this timeline more than anything else. The first is a complete brief at the start: dimensions with tolerances, material callouts, Pantone references and vector artwork routinely remove an entire sampling round. The second is decision speed at each gate — the slowest programmes are almost never limited by production capacity, they stall on buyer-side approvals, which is exactly why one merchandiser chases every open item daily until the specification freezes.

It is also worth knowing what does not happen. We do not quote a low headline price and recover it later through tooling or packaging surcharges, and we do not start bulk cutting before a pre-production sample is approved and sealed. Both practices are common in this category; neither survives a second order.

How to Write an RFQ That Gets a Firm Price

A vague enquiry gets a range; a specific one gets a number you can contract on. The difference is not formality — a bullet list in an email is perfectly fine — it is whether the ten variables below are stated. Buyers who cover eight or more of them typically reach a firm price in one round instead of three.

• Product type and dimensions: length, width, height or diameter, with capacity measured or targeted
• Material and denier: PVC tarpaulin, TPU laminate or coated nylon, and the weight in denier
• Closure system: roll-top, water-resistant zip, airtight zip, or lid and drawcord
• Waterproof target: IPX6, IPX7, IPX8 or a hydrostatic head figure, plus how it will be tested
• Colourways: how many, and Pantone references where they exist
• Branding: method (silk-screen, heat transfer, TPU patch, embroidery) and placement
• Quantity: pieces per style and per colourway — this drives almost everything in the price
• Packaging: bulk polybag, retail box, hang tag, FSC carton
• Destination: port for FOB/CIF, or full address for a DDP landed quote
• Target delivery date: so buffer can be built into the schedule rather than hoped for

If you do not have a tech pack, send what you do have. A physical reference sample with a marked-up photograph and a target quantity is enough for a budgetary quotation within 24 hours, and it lets us tell you early whether a feature is cost-prohibitive — far cheaper to learn before prototyping than after it. Our custom waterproof bag manufacturer guide includes a specification checklist you can fill in and return, and the custom waterproof bags page maps the full development route.

One more variable is worth volunteering even though it is not asked for: what you are comparing against. Whether you are benchmarking an incumbent supplier, a domestic quote or a target retail price tells us where to engineer — and it is often the difference between a quotation you reject and one you can use.

Commercial Terms at a Glance

These are the standard commercial parameters, stated up front because the fastest way to lose a week in a negotiation is to discover a mismatch on payment terms or Incoterms after the technical work is already done.

Tooling is the line item first-time buyers most often miss, so it is worth stating plainly: cutting dies run USD 80–300 per style, printing plates USD 30–80 per colour, and custom hardware or back-panel moulds USD 500–3,000 where proprietary components are specified. It is always quoted separately rather than folded into unit price, because a blended price hides tooling and makes every future reorder impossible to benchmark.

Payment structure deserves a sentence of context. The 30% deposit buys material and line scheduling; the 70% balance is released only against a passed AQL 2.5 inspection report, which means you are not paying in full for goods nobody has inspected. Buyers who have completed three successful orders can move to 20/80 or net-30, and first transactions above USD 50,000 can be secured by L/C at sight through your bank.

Shipping, Freight and Landed Cost

Waterproof bags are bulky relative to their weight, so freight is charged volumetrically and the Incoterm you choose materially changes landed cost. We quote both FOB and DDP on request so the comparison can be made against your own forwarder’s rate rather than guessed at.

Packing efficiency deserves a note because it is the quietest lever on landed cost. Products ship flat-packed and nested where geometry allows, and detachable harnesses, straps and hardware packed separately can lift units per container by 15–20%. On a 10,000-unit order that difference is worth more than most price negotiations, so we run a packing simulation before quoting freight rather than estimating from a carton count.

DDP is available to 100+ countries and covers freight, customs clearance, duties and last-mile delivery. It suits first-time importers and e-commerce operators who want a single landed number; buyers with their own broker and a bonded relationship usually save money on FOB. Both are quoted with freight and duty itemised separately, so procurement can audit the numbers instead of trusting them.

Samples, NDA and Design Protection

Sampling is where a programme becomes real, and it is also where intellectual property first changes hands. Both are handled with the same structure on every enquiry, and neither requires you to ask.

Prototype samples carry a development fee of USD 80–150 per sample depending on complexity, credited in full against the first bulk order of 1,000 pieces or more. Express courier is billed at cost with no handling markup. Pre-production samples from the actual production line are included once a bulk order is confirmed, and that sample becomes the sealed golden sample governing every inspection gate that follows.

NDAs are standard and can be executed before any tech pack or artwork is shared. Beyond the NDA, custom developments carry style-level exclusivity as a default: a silhouette, closure or fabric programme you paid to develop is not offered to another buyer. Custom tooling and proprietary hardware remain your property and are released on request. The carve-outs are honest ones — standard closures, generic patterns and shared component platforms are not exclusive by definition, and we say so up front rather than letting it surface later.

If you have an existing product you want matched, send it. Reverse-engineering a reference sample is routine: materials, construction, hardware and coating are identified, a matched build is quoted, and any engineering improvements worth making are flagged separately. Where a component is proprietary or tooling-heavy, we propose the closest functional equivalent and price both, so the decision is yours with numbers attached.

Quality, Inspection and After-Sales

Quality control runs at three gates — incoming material, in-line, and AQL 2.5 pre-shipment inspection to ISO 2859-1 — with waterproof-specific tests written into the protocol per style rather than improvised at the container door. Welded stations run daily peel-test coupons, and closure cycle, submersion and hydrostatic head tests are recorded against the batch.

The golden sample system is what protects you across reorders. The approved pre-production sample is sealed, photographed and signed, and every bulk inspection measures against it dimensionally, by weight and visually. That removes the most expensive argument in custom manufacturing — whether the bulk matches what was approved — because the reference is physical, dated and acknowledged by both sides before production begins. The full protocol is set out on our quality control page.

You and your nominated inspectors are welcome at any gate. SGS, QIMA and TÜV inspectors are routinely hosted; where travel is impractical we run live video audits plus daily photo reports from the line. The warranty runs twelve months from the date of shipment against manufacturing defects; claims are logged with photographs and quantity, assessed against the golden sample and inspection record, and settled by replacement, credit or remake.

Which Channel Should You Use

Different questions deserve different channels, and picking the right one is usually the difference between an answer today and an answer on Thursday.

Business hours are Monday to Saturday, 09:00–18:00 GMT+8. Messages received outside those hours are answered at the start of the next working day. Buyers in the Americas who send briefs overnight typically find a full quotation waiting at the start of their own morning — a quiet advantage of working across the timezone rather than against it.

Company background, capacity evidence and compliance certificates sit on our about page; the production floor, welding capability and line structure are covered on the manufacturing page. If you would rather read first, start there — and if you are deciding between development routes, the services page maps white label through to full custom programmes.
