Knitted Bag Sourcing Checklist: Twelve Gates, Fourteen Numbers and the Cost of Skipping Each

The Fourteen Numbers That Decide a Knit Programme

Fourteen numbers decide whether a knit sourcing decision holds, and eight of them have to be in writing before a purchase order goes out: gauge, yarn count, finished GSM, MOQ per colourway, sampling window, bulk window, inspection level and term.

The reason to insist on numbers rather than adjectives is that knitting is a programmed process. A loop length, a needle set-up and a yarn count produce a fabric with a measurable GSM, and that GSM sets the weight of the bag, the hand of the bag and the cost of the bag at the same moment. A vendor who calls a fabric medium weight has given nothing that can be checked against a delivered carton, while one who states 420 g/m² has given a figure that can be weighed at the receiving dock.

• Gauge: E7, E12 or E14. This sets loop size, surface definition and how much structure the panel carries before any lining is added.
• Yarn count: 600D for a structured tote, 300D for a mid-weight body, 150D for a light packable piece, with the fibre stated.
• Finished GSM: a number measured after conditioning, not a description. On a knitted tote the working band is 380 to 520 g/m².
• MOQ per colourway: 100 pcs per style and per colourway, because each shade is its own yarn set-up.
• Sampling window: 7 working days from an approved digital file, with the number of correction rounds stated.
• Bulk window: 30 days from handover of an approved sample, measured to the readiness date rather than to the vessel.
• Inspection level: AQL 2.5 under an ISO 2859-1 sampling plan, with the sample size and the accept and reject counts.
• Term: FOB Xiamen, with CIF and DDP available against a named destination port or address.

The other six sit behind the first eight and are usually discovered late: how many colourways one MOQ buys, the shade tolerance in Delta E, the join method at the handle, the packaging route, the standard named on the lab certificate, and the validity date on the quotation. Those six are where a programme quietly drifts, because none of them appears on a hangtag and all of them appear on an invoice.

Gate by Gate: What Each Check Costs When It Is Skipped

Every gate has a failure cost, and the four most expensive ones are GSM, yarn count, inspection level and ownership of the programme file; a GSM that was never written down moves the unit price by 8 to 12 percent on the first revision, which is more than most buyers save in a season of negotiation.

Two of those rows deserve a second look. Gate 4 is the one buyers misread most often: MOQ of 100 pcs is per style and per colourway, so a programme of three shades at 100 pcs each is a 300-piece order, not a 100-piece order. Gate 8 is the one buyers under-specify: FOB is meaningless without the named port, and the ICC Incoterms 2020 rules exist precisely so that risk transfer, cost division and document obligation are settled by a rule rather than by a conversation.

Time Arithmetic: 7 Working Days, 30 Days, and Where Both Slip

A knit programme runs on two clocks, 7 working days for sampling and 30 days for bulk, and both slip at the same place: the moment between an approved sample and a frozen specification.

1. Day 0 to day 2: the digital file is programmed and the first knit is produced. This is where a structural unknown surfaces.
2. Day 2 to day 4: correction round one. On an E12 tote this is usually a loop-length or a dimension change, not a re-programme.
3. Day 4 to day 7: the approved sample is finished, measured, photographed and released for the buyer to sign.
4. Handover: the specification is frozen. Bulk of 30 days starts here, and not before.
5. Day 1 to day 10 of bulk: yarn is booked and the bed slot is confirmed. Capacity is 7 production lines at about 200,000 pcs per month.
6. Day 10 to day 26 of bulk: knitting, joining, hardware, finishing and packing.
7. Day 26 to day 30 of bulk: inspection at AQL 2.5 under ISO 2859-1, carton packing and handover under the agreed term.

The slip almost never happens inside the two windows. It happens in the gap a buyer creates by approving a sample verbally and sending the written specification a week later, during which the yarn has been booked against the verbal version and the bed slot has been released to another programme. Writing the specification down on the day the sample is approved is the single least expensive move on this entire checklist.

Capacity and Release: Reading 7 Lines Without a Site Visit

Capacity is 7 production lines at about 200,000 pcs per month, and the number a buyer actually needs is not the monthly figure but the bed slot: which week, on which line, under which programme number.

Three questions settle it. First, is the slot booked or pencilled? A booked slot has a week number and a programme reference; a pencilled one has neither and will be released the moment a larger programme appears. Second, what happens to the slot if the sample fails twice? A honest answer is that the slot moves; an evasive answer is that the slot is held indefinitely, which no production floor with 7 lines can promise. Third, is the inspection report issued against the same programme number that appears on the carton label? That single check catches more mismatches than any other on this list.

Release is the other half. A run is released against AQL 2.5 under ISO 2859-1, and the report should carry the sample size, the number of minor and major defects found, and the accept and reject counts for that sample size. A report that says passed with no numbers is not an ISO 2859-1 report. For the defect vocabulary that belongs on that report, see knitted bag quality control.

Compliance Files: Which Certificates Actually Travel With the Goods

Four documents travel with a knit shipment and four do not; the four that travel are the commercial invoice, the packing list, the bill of lading or air waybill, and any certificate the destination market requires by law, while the audit reports stay on file at the production base.

The distinction between a scope certificate and a transaction certificate causes more confusion than any other compliance question on this checklist. A scope certificate says a site and a product group are certified. A transaction certificate says this lot, in this quantity, with this recycled content, moved from this site to this buyer. Buyers asking for the second one get a document that means something; buyers accepting the first get a document that means the site was audited at some point.

Cost Structure: What Sits Inside the Unit Price

The unit price on a knitted bag covers yarn, knitting time, join and finishing operations, hardware and packing; it does not cover development, lab testing, packaging beyond a polybag, or freight, which is why a quote total and a landed total are never the same figure.

Yarn

300D or 600D polyester, or a GRS-certified recycled equivalent at a premium per kilogram

Knitting time

Machine minutes per panel; an E12 tote body runs materially longer than an E7 one

Join and finishing

Handle join method, edge treatment, steaming and shaping

Hardware

Zips, sliders, D-rings, magnetic closures, foot studs

Packing

Polybag, sleeve, mailer, box or pouch, before any print set-up

Outside the unit price

Development, lab testing, onward freight, duties, destination handling

Reference unit price

USD 4.80 for an E12 knitted tote at a mid-volume quantity, FOB Xiamen

The line that catches buyers out is knitting time. Machine minutes are a real cost on a knitting bed in a way that cutting time is not on a cut-and-sew line, because a bed produces one panel at a time and the programme runs whether or not the yarn is expensive. A buyer negotiating yarn price on a structure that runs 14 minutes a panel is negotiating the wrong line. On a structured body the minutes move the number; on a packable 150D piece the yarn does.

IP and Tooling: Who Owns the Programme File

The knitting programme is the tooling on a knit bag, and ownership of it should be settled in writing before the first sample: the buyer owns the design and the artwork, the production partner owns the machine file unless it is assigned, and the two are different assets.

Three clauses settle it. The first assigns the machine file, or states that it does not transfer and that the programme stays with the production base for reuse only on that buyer's orders. The second covers the artwork and any registered design, which are protected under national design law and, for cross-border filing, under the WIPO-administered Hague system for industrial designs. The third covers the physical sample: who may photograph it, when it may be shown, and whether it may appear on a stand. Without the third clause a sample shown at a trade fair is a design released into the market at no cost.

The Twelve Gates in One Table

Twelve gates, in the order a buyer should run them, with the answer that should come back from a credible knit programme: eight technical and commercial, two documentary, one legal and one scheduling.

Reading the Answers: Three Signals That Predict a Bad Programme

Three answers predict a difficult programme more reliably than any certificate: a GSM given as a description, a bed slot given without a week number, and an inspection report given without a sample size.

None of the three is a dishonest answer. They are all answers from a party that has not yet built the habit of measuring, and a party that does not measure cannot hold a tolerance, cannot reproduce a shade, and cannot tell a buyer whether a run of 2,000 pcs matches a sample of three. The pattern to watch for is not hostility to the question but surprise at it. A programme that has run knit bags since 2014 answers all three without looking anything up.

The counter-signal is just as useful. A vendor who answers a GSM question by quoting a conditioning standard, answers a slot question by quoting a week, and answers an inspection question by quoting ISO 2859-1 sample sizes has told a buyer more in three sentences than a brochure does in twelve pages. Those are the programmes worth a sample order at 100 pcs.

Turning the Checklist Into a Brief

A checklist is only useful if it becomes one document, and the conversion is mechanical: every gate becomes a field, every number becomes a value, and every value the buyer does not yet know is marked provisional rather than left blank.

Marking a value provisional is the move that separates a brief that prices from one that stalls. Gauge and handle drop are commonly provisional at brief stage and are settled during the 7 working days of sampling. GSM, yarn count and quantity are not provisional; they stop a quote when missing, because a quote built on an assumed GSM is a quote that moves. Send the document once, name one person who can answer technical questions during the window, and the twelve gates turn into a purchase order rather than a correspondence.

A Checklist Is a Decision, Not a Form

The value of twelve gates is not that they are thorough. It is that they are ordered, and the order means a buyer stops at the first unanswerable question instead of discovering it after a container has shipped. Eight numbers, written down, settle more than any audit.

Send the eight you have, mark the rest provisional, and name one person who can answer during the window. For the full sourcing framework these gates sit inside, see knitted bag sourcing guide. For the defect vocabulary used at the release gate, see knitted bag quality control.
