Two suppliers quote the "same" canvas tote at USD 1.10 and USD 2.30. Neither is necessarily lying. One is quoting 8 oz fabric with a single-colour print and no interlining; the other is quoting 12 oz with a base panel, a zipper and a two-colour print. Until the specification matches, the prices cannot be compared.

This breakdown shows what actually sits inside a bag price, so you can read a quotation, spot the differences, and negotiate on the right line.

The six cost blocks

Freight, duty and inspection sit outside the FOB price and are discussed below, because they are where budgets usually break.

1. Fabric: the biggest lever

A 38 × 42 cm tote with two handles consumes roughly 0.55–0.65 m² of fabric including cutting waste. At 10 oz (340 g/m²) that is about 200 g of cotton per bag; at 12 oz it rises to about 240 g.

Cotton canvas typically costs USD 2.20–3.20 per kilogram in greige, more once dyed and pre-shrunk. That puts raw fabric at roughly USD 0.45–0.65 per bag at 10 oz — before waste, which runs 5–8% on a simple pattern and 12%+ on a curved or multi-panel design.

Three things change this number quickly:

• Weight. Each step up (about 2 oz) adds 15–25% to fabric cost.
• Colour. Piece-dyed or custom-dyed fabric costs more than natural, and carries a higher minimum because the mill dyes in batches.
• Certification. GOTS organic cotton adds 15–30% to the fabric line, and often another week of lead time.

2. Trims: small items, surprising totals

Handles are the main cost here. Cotton webbing is cheaper than leather; a padded handle, a metal adjuster or a riveted attachment each adds a line. Linings, internal pockets, zippers and branded metal hardware can add USD 0.20–0.80 per bag depending on quality — frequently more than the difference between 10 oz and 12 oz fabric.

This is the block where cheap quotes hide. Ask what the handle is made of, how it is attached, and whether there is any interlining. "Same style" can mean cotton webbing stitched flat, or polyester webbing with an X-box stitch and a plastic slider.

3. Printing: setup plus run

Printing is two costs, not one:

• Setup — screens (one per colour per position), digitising for embroidery, or a transfer plate. Screen charges typically run USD 15–35 each in China. These are one-off per design, but you pay them again for every colour and every new version.
• Run cost — ink, labour and machine time per piece. This falls with volume, but not as fast as buyers expect, because each bag still passes through the press.

At 100 pieces, setup can be 15–25% of the unit price. At 5,000 pieces it is under 1%. This is the main reason small orders look expensive per unit — and the main reason consolidating versions saves more than squeezing the fabric price.

4. Sewing labour: complexity, not size

Labour is driven by the number of operations, not by bag dimensions. A simple open tote is roughly 12–16 operations: cut, fold, hem, attach handles, bartack, trim, inspect. Add a lining, an internal pocket, a zipper and a base panel and you can double that.

Where labour shows up in quality: stitches per inch (8–10 is normal), bar tacks at handle ends, and whether the seam allowances are overlocked or bound. A supplier quoting a lower price is often reducing operations, not wages.

5. Packing: small, but it decides your landed cost

Packing is 3–8% of FOB but it controls shipping volume, which can be a bigger number than the packing itself. Compressing bags into a smaller carton can cut ocean freight by 10–20% on a light, bulky product like canvas.

Typical line items: individual polybag or paper band, hangtag and its attachment, barcode sticker, silica gel, master carton (5-ply for export), and carton markings. Ask for carton dimensions and pieces per carton early — it is the only way to compare freight quotes properly.

6. Overhead and margin

Factory overhead is spread across orders, so bigger orders carry less per piece. Margin depends on how busy the factory is: in a slow season you will see 8%, in peak season 15% for the same product. This is why quotes expire, and why a re-quote three months later is not the same price.

Indicative price bands

The table below is for budget planning only. It assumes a plain cotton canvas tote, 38 × 42 cm, two webbing handles, one-colour one-position screen print, individual polybag, FOB Ningbo/Shanghai, and prices in 2026. Your specification will move these numbers.

If a quote lands far outside these bands, the difference is diagnostic: either the specification is different from what you assumed, or something is being left out of the price.

Setup costs and how they amortise

Setup is fixed, so its effect on unit price is pure division:

• Three-colour print, three screens at USD 25 = USD 75.
• At 100 pieces: USD 0.75 per bag added.
• At 1,000 pieces: USD 0.075 per bag.
• At 5,000 pieces: USD 0.015 per bag.

Same screens, same print, 50× difference in per-unit impact. Reducing colours from three to one saves USD 50 in setup and simplifies approval — often a better trade than arguing over 3% on fabric.

Landed cost: what the FOB price does not include

Buyers routinely budget on FOB and get surprised at the door. Build these in:

• Freight. Canvas is light but bulky; you pay for volume, not weight. Sea LCL for 1,000 bags is usually a few hundred dollars; air freight can exceed the goods value.
• Duty and tax. Depends on HS code, origin and current trade measures — for China-origin goods, additional duties can change the number substantially. Confirm the rate for your destination before you cost the order, then add VAT or sales tax.
• Destination charges. Port handling, customs clearance, documentation, and delivery from port — often USD 300–800 on a small LCL shipment.
• Inspection. A third-party pre-shipment inspection typically costs USD 250–350 per man-day. On a 1,000-piece order that is USD 0.25–0.35 per bag — cheap insurance.
• Payment friction. Bank charges on a T/T transfer, and currency movement between quotation and payment.

How to read a quotation

A quote that cannot answer these ten points is not yet a quote:

1. Unit price and Incoterm (FOB port, CIF, DDP).
2. Fabric: GSM, fibre content, and tolerance.
3. Bag dimensions and handle specification.
4. Print method, number of colours, print area, and whether setup is included.
5. Sample cost and lead time.
6. Production lead time from artwork approval, not from deposit.
7. Packing: polybag, hangtag, carton grade, pieces per carton, carton size.
8. Payment terms.
9. Validity period of the price.
10. What happens if the order quantity changes by 20%.

Seven legitimate ways to reduce cost

• Reduce colours. Each colour is a screen, a pass and an approval risk.
• Standardise sizes. One size across a range saves cutting setup and fabric waste.
• Consolidate quantity. 1,000 of one design beats 500 of two, usually by 15%.
• Use natural or stock fabric colours. Custom dyeing adds cost and a minimum batch.
• Simplify trims. Flat-stitched webbing instead of a padded handle with hardware.
• Optimise packing. Smaller carton, fewer inner bags — reduces freight, not quality.
• Book production in the low season. February to April is quieter than August to November.

What is not a legitimate way: asking for 10 oz and accepting 8 oz, or accepting a lower AQL without knowing it. Those savings appear on the invoice and disappear in the first month of use.

When a price is too low

A quote 30% below the market for a fully specified bag usually means one of five things: lighter fabric, fewer stitching operations, cheaper trims, no inspection, or a specification that will change after the deposit. Ask which. A supplier who can explain where the saving comes from is negotiating; one who cannot is planning to disappoint you.

Frequently asked questions

Why did my price go up on reorder?

Cotton prices, exchange rates, labour and factory loading all move. Ask for the changed cost line rather than a new total, and check whether the specification shifted too.

Is it cheaper to order from a trading company?

Rarely on unit price, sometimes on total cost — if they handle consolidation, inspection and documentation better than you can. Compare landed cost and risk, not FOB.

Can I get a lower price by paying 100% upfront?

You can sometimes get 2–5%, but you lose all leverage on quality and delivery. A 30/70 split with an inspection clause is worth more than the discount.

How much should a sample cost?

USD 30–100 for a custom bag, often credited against the bulk order. A free sample is usually a stock item, not your specification.
