Hardcover Threadsewn Notebook OEM: A5 Casebound Specs & MOQ

💡 A Real Inquiry: Hardcover Threadsewn Notebooks

A European distributor sent us this spec last week:

This is a classic premium notebook request — and a useful one to decode, because every line in that spec sheet affects price, lead time, and quality. If you are sourcing hardcover threadsewn notebooks (also called casebound notebooks or sewn-bound notebooks) from China, here is exactly what those specifications mean, what they cost at different quantities, and what MOQ you should plan around.

📖 What "Threadsewn" Means and Why It Matters

Threadsewn (or sewn) binding means the pages are physically stitched together with thread before the cover is attached. It is the difference between a notebook that lies flat and lasts for years, and one that sheds pages after a few months.

Three binding types dominate the notebook market:

Binding	Durability	Lay-flat	Typical Use	Relative Cost
Perfect bound (glued)	Low–medium	No	Notepads, journals	Lowest
Threadsewn / sewn	High	Yes	Premium notebooks, Bibles	Medium
Casebound + threadsewn	Highest	Yes	Corporate gifts, executive journals	Highest

The inquiry above is a casebound + threadsewn construction: a rigid grey-board cover wrapped in laminated art paper, with a sewn text block. This is the configuration corporate gift buyers request when they want a notebook that feels expensive in the hand.

📐 Breaking Down the Spec Sheet

Each line of the specification is a decision that moves the price:

Spec	What It Means	Cost Impact
157gsm matt art + matt lamination	Coated paper wrapped over the board; lamination protects and gives soft-touch feel	Higher than uncoated, standard for premium
1.5mm grey board	Rigid cover thickness; 1.5–2.0mm is the premium range	Board cost scales with thickness
80gsm woodfree	Standard writing paper; no show-through at 80gsm with 4C printing	Baseline
160pp (80 sheets)	Substantial page count; needs sewn binding to hold well	Paper is the biggest material cost
4C x 0C cover / 4C x 4C text	Full-colour cover, full-colour inside pages	4C text doubles print cost vs 1C
Round corners (two sides)	Die-cut rounded corners on the binding-side corners	Adds die-cutting step, small cost

If you are comparing factory quotes, always compare the same specification. A quote for 100gsm text paper and one for 80gsm can differ by 10–15% before any negotiation.

💰 MOQ Reality: 200 Units vs 1,000 Units

Here is the honest answer on quantity. A factory can produce 200 hardcover threadsewn notebooks — most print shops in Guangzhou and Shenzhen will accept the order. But at 200 units, the unit price is noticeably higher, because the fixed costs (plates, dies, board cutting, setup) are spread over a small run.

Typical unit price guidance for this exact specification (FOB Guangzhou, 2026):

Quantity	Unit Price (FOB Guangzhou)	Best For
200	5.5–7.5 USD	Samples, small launches, client gifts
500	4.0–5.5 USD	Test markets, events
1,000	3.2–4.5 USD	First commercial order
3,000+	2.7–3.8 USD	Distribution, retail programs

FOB Guangzhou. Shipping to destination port is additional. Prices vary with exact paper brand, foil stamping, ribbon, and packaging.

🏭 The Manufacturing Process, Step by Step

Understanding the process helps you ask the right questions and set realistic timelines. A casebound threadsewn notebook goes through five stages:

1. Printing (2–3 days): Cover and text pages printed 4C. Colour-critical work gets a proof first.
2. Cover making (2–3 days): Art paper laminated, wrapped around 1.5mm grey board, corners rounded with a die.
3. Threadsewing (2–3 days): 160pp signatures sewn on a thread-sewing machine — this is the step that gives the notebook its lay-flat strength.
4. Casing-in (2 days): Sewn text block glued into the rigid cover, pressed until dry.
5. Finishing & QC (2–3 days): Round-corner check, edge trimming, ribbon/bookmark optional, shrink-wrap or gift-box packing.

Typical total lead time for 1,000 units after artwork approval: 15–20 working days (25–30 with sea shipping). Samples take 7–10 days and are strongly recommended before a production run.

✅ What to Check Before Placing the Order

Five quality points that separate a good factory from a bad one on this product:

• Corner radius consistency — round corners must match across cover and text block; uneven corners are the most common defect on this spec.
• Lamination adhesion — matt lamination that peels at the spine edge after a few weeks of use is a silent quality killer.
• Sewn signatures alignment — open a random sample: pages should lie flat and the stitching must be invisible from the outside.
• Board warp — grey board should stay flat after casing-in; warped covers indicate rushed drying.
• Colour match to proof — ask for a printed proof (soft proof or physical) before the full run, especially for 4C x 4C text.

❓ Frequently Asked Questions

Can 200 notebooks really be produced?

Yes. 200 pieces is an accepted minimum for this construction in most Guangzhou print shops. The unit price will be roughly 30–50% higher than at 1,000 units, and some factories add a small order handling fee. It is a good quantity for samples and small corporate gifts, not for a commercial program.

Why is the price much higher at 200 units?

Fixed costs — printing plates, board dies, round-corner dies, machine setup, and colour proofing — are the same whether you order 200 or 2,000. Spread over fewer units, each notebook carries more of that fixed cost. That is why unit price drops sharply between 200 and 1,000.

Is 80gsm woodfree good enough for full-colour printing?

Yes. 80gsm woodfree (uncoated, high-whiteness) is the standard for notebook text pages. With 4C x 4C printing you get clean colour with minimal show-through. If the design has heavy ink coverage, some buyers step up to 100gsm — expect roughly a 10% paper cost increase.

What does "round corners at two sides" mean exactly?

It means the two corners on the opening side of the notebook (top-right and bottom-right when closed) are rounded with a die, instead of sharp square corners. It is a premium aesthetic detail common on executive and gift notebooks. Some buyers ask for all four corners — confirm which one your design needs.

Can I get a sample before bulk production?

Yes, and we recommend it. A pre-production sample (with your artwork, or a blank mock-up) takes 7–10 days. For threadsewn casebound notebooks, the sample is where you verify corner radius, lamination feel, and lay-flat performance before committing to the full run.
