How We Work · From First Enquiry to Repeat Order

Ten Steps From First Enquiry
to Repeat Order.

A bulk bag order follows a fixed path: understanding the application, confirming the six points that make a quotation possible, agreeing the specification, validating a sample, and then production, inspection, shipment and the first use that decides the repeat order. Every step below states what we need from you, what you get back, and what has to be in writing before the next one starts.

The Path

The Ten Steps, and What Each One Owes You.

Every step states what you provide, what we deliver and what is confirmed in writing. Nothing moves on to the next step on a phone call alone.

01

Understand Your Application

The first reply comes before any price. We want to know what the bag has to do.

You provide
The material you fill, the weight each bag has to carry, the size or capacity you need, any photo, drawing or bag you use today, the quantity you have in mind, and the destination country, city and postcode.
We deliver
A reply within one working hour in working hours — enquiries that arrive outside them are handled first in the next working period — and the shortest list of questions that still lets us quote.
In writing
A customer number and a project number, so the enquiry lives in one record instead of in a chat thread.
02

Confirm Basic Requirements

Six answers are enough for a first judgement. We do not open with a technical questionnaire.

You provide
Confirmation of those six points, plus the company name, the country, your role in the purchase, and whether the bags are for your own use, for resale or for your own customers.
We deliver
A check that the requirement sits inside our capability, and a decision on the route: a budgetary quote, a technical review, or one clarifying question first.
In writing
The verified customer and project record, and the answers as they stand.
03

Develop a Preliminary Solution

A budgetary figure that shows the shape of the cost, with its assumptions on the table.

You provide
The state of the material, how the bag is handled and lifted, and what goes wrong with the bag you use today.
We deliver
A budgetary quote — four working hours for a mature product, twenty-four hours when the factory has to cost a non-standard bag — and a straight answer when a figure cannot be given honestly yet.
In writing
The quote is marked Preliminary or Budgetary, states that it is not the final offer, and lists the size, SWL, structure, quantity, packing and trade-term assumptions it rests on, together with the items still open.
04

Confirm Detailed Specification

Thirteen points, pre-filled wherever we already know the answer.

You provide
The remaining points of the specification: material and its state, load per bag, size or capacity, body construction, top and bottom design, loop type and lifting method, coating, venting, liner, UV, food-contact, UN or other function, colour, printing, labelling and packing, quantity per specification, destination and trade term, and the photos, drawings or samples you hold.
We deliver
A one-page specification sheet with a bag diagram, filled in by your contact, with any special structure marked on your own photo or drawing. Where the original design carries a technical risk we present your requirement and a QINFENG option beside it, each with its own specification number.
In writing
Every unknown point is marked "to be confirmed" rather than guessed, and you select the final option in writing.
05

Sample and Validation

A sample answers a question. We agree on the question before it is made.

You provide
What the sample has to prove — dimension, structure, material, printing, feel, lifting, and whether load or compliance testing is required — and the courier cost on a free stock sample.
We deliver
One or two unprinted stock samples free of charge, or a made-to-order sample against sampling, plate and material cost; five to eight days for a standard sample and seven to ten for a new structure, material or complex process; and a sample number, specification sheet, photographs and courier record.
In writing
You confirm the final specification table through a traceable channel — "sample approved" on its own is not enough — with dimension, structure, material, loops, top, bottom, liner, printing, colour and packing confirmed item by item.
06

Quotation and Order Confirmation

The formal quotation is the document the whole order is measured against.

You provide
The quantity for each specification, the destination and the trade term, and your decision between the options on the table.
We deliver
A formal quotation carrying the specification number and version, quantity per specification, unit and total price, packing, plate, sample, testing and pallet charges, trade term, destination, payment terms, validity, production lead time, a freight transit note, and what is included and what is not.
In writing
The proforma invoice confirmed by both sides, the final specification table, the printing artwork with its colours, fonts and positions, and the sample or test result — or your written agreement that no sample is made.
07

Production and Quality Control

Thirty-five to forty-five days, counted from the day everything is confirmed rather than the day the order arrives.

You provide
A decision on any point still open, and a written change request if the specification moves after scheduling.
We deliver
Incoming material checks on PP supplier, grade and batch, mother colour and UV additive, webbing and liner; first-article confirmation before the run continues; in-process patrol on stitching, stitch pitch, hem, loop overlap, dimension, print version and liner assembly; final inspection with performance sampling; and a shipping release signed by the quality lead.
In writing
The first-article record, the in-process and final inspection records and the shipping release — and, if the specification changes, the new cost and the new lead time in writing before anything else moves.
08

Packing and Shipment

Ten conditions are settled before a container is released for loading.

You provide
Confirmation of packing, labels, manual and pallet requirements, and the balance payment where the order is not on agreed credit terms.
We deliver
Packing to the instruction with cross-checking and physical separation for multi-specification orders; booking, customs declaration and the document set issued from Qingdao; and loading photographs with the actual quantity.
In writing
The packing and loading check sheet, the shipping release, and the packing list, commercial invoice and customs data checked against each other.
09

Delivery Follow-up

Nine updates between Qingdao and your door, each separating the estimate from the fact.

You provide
For a DDU or DDP order, the full delivery address, the postcode, whether the site is commercial or residential, the unloading equipment available, and whether a delivery appointment or a tail-lift truck is needed.
We deliver
A proactive update at booking and loading, dispatch from the plant, loading completion with photographs and the actual quantity, the actual departure and the estimated arrival, the bill of lading draft and the final documents, any transhipment, rollover or changed arrival, a reminder before arrival, clearance and delivery for DDU and DDP, and a confirmation after receipt.
In writing
Every update separates the estimated time from what has actually happened.
10

Repeat Order Management

The first order is a trial. The tenth is a specification you no longer have to explain.

You provide
The actual loading weight, the behaviour in filling, lifting, transport, storage and discharge, and the points you want kept or changed.
We deliver
A fixed specification version held against your account, a re-check of quantity, PP price, freight and lead time before each order, and a question about consumption and stock cycle before your next buying window.
In writing
The trial result confirmed in writing before it becomes your repeat standard, with any modification written into a new specification version.

HOW WE WORK

From your application to an approved production specification.

Many FIBC problems begin before production — with an incomplete specification. Our process is designed to confirm the important details early, so the factory, the buyer and the end user are working from the same requirements.

01

Application Review

Product, density, load and handling conditions.

02

Specification

Bag type, fabric, top, bottom, loops and options.

03

Quotation

Clear commercial offer based on the confirmed design.

04

Sample

Physical confirmation where project testing is required.

05

Production & QC

Manufacturing against approved requirements.

06

Shipment & Repeat

Export delivery and repeat-order specification control.

Sample and Validation

A Sample Answers a Question. We Agree the Question First.

A sample is not a formality. It is the cheapest place to find out whether the bag behaves the way your filling line, your lifting equipment and your storage expect it to.

  • One or two unprinted stock samples are free of charge; you carry the courier cost.
  • A made-to-order sample is charged against sampling, plate and material cost, and whether it is credited against the formal order is agreed per project.
  • Standard sample: 5–8 days. New structure, new material or complex process: 7–10 days, or as the factory confirms.
  • Every sample is registered with a number, a specification sheet, photographs, a courier record and the validation target it was made for.
  • A bag you send us is photographed, measured and kept for the production run, and it is not shown to another customer.

A plain sample does not by itself prove SWL, food-grade or UN status. Those are separate tests with their own scope, sample quantity, report language and cost, agreed before they are ordered.

To Start

Six Answers Start a Real Quotation.

The first round is deliberately short. These six points are enough to judge the product and the risk, and to say whether a budgetary price can be given at all.

  • What the bag will hold. The material and its state.
  • The weight each bag has to carry. The actual load, not the bag size.
  • The size or capacity you need. Or the dimensions of the bag you use today.
  • A photo, a drawing or the bag itself. Anything that shows the structure and the lifting arrangement.
  • The quantity for this first order. And, where you know it, the quantity per size.
  • The destination country, city and postcode. So the trade term and the freight can be priced.

What we will not promise before we know

  • A load rating taken from a blurred photograph.
  • A firm DDP price without the quantity and the destination.
  • A general industry specification treated as your final specification.
  • Food-grade, UN or anti-static approval before the technical review.
  • A rush lead time before the factory has confirmed capacity.

Trial to Repeat

The Trial Order Is Where the Specification Gets Settled.

A first order is a test under your conditions, not only ours. What it teaches is written down, so the second order starts from a fixed version instead of from memory.

01

Receipt

Quantity, packing, labels and transport condition confirmed on arrival, and anything visibly damaged reported before the bags go into store.

02

First use

The actual load, and the filling, lifting, transport, storage and discharge behaviour, recorded against the specification.

03

New version

Anything that has to change is written into a new specification version rather than remembered for next time.

04

Repeat standard

Your fixed version, the consumption and stock cycle, and a re-check of quantity, PP price, freight and lead time before the next order.

An annual framework becomes available once two or three orders are complete, payment is on time, no major complaint is open and the specification is stable — with the forecast, ordering, payment and price-adjustment mechanism agreed in advance.

Process Questions

The Questions a New Buyer Asks First.

The first reply comes within one working hour in working hours. A budgetary quote takes four working hours for a mature product and twenty-four hours when the factory has to cost a non-standard bag. A standard sample takes five to eight days, a new structure or material seven to ten. Production is 35–45 days from the working day after the prepayment and the full confirmation; international transport, customs clearance and final delivery come on top of that.

A sample is the normal route, because it is the cheapest place to catch a problem. If you would rather not make one, the order can still be scheduled once you agree in writing that no sample is made — the final specification table, the printing artwork and the proforma invoice are confirmed either way.

Four things: the final specification table, the sample approval against that table, the proforma invoice together with the printing artwork, and any change made after scheduling. A change that exists only in a chat thread does not count.

Yes, through a written request. We check the current production progress, the factory assesses whether the change is still possible, and the material waste, plate, labour and delay cost is worked out. You receive the new cost and the new lead time in writing; once you accept in writing, the proforma invoice, the specification table, the artwork and the version number are updated and production continues. Work already completed, or impossible to rework, stays with the order.

We collect the order number, the specification, the batch, the quantity affected, photographs or video, the position of the damage, the actual load, the material, and how the bags were lifted, stored and transported. If it is a serious safety issue we advise you to stop using the same batch at once. We then pull the material, production, inspection and packing records and investigate with sales, production and quality together. If the cause is ours, the remedy is replacement, an offset against a following order or an approved compensation; if it is not, you still receive the technical finding and the improvement advice in writing.
