The Apparel Manufacturing Process: From Sampling to Bulk Production

(Step-by-Step Breakdown with Timelines)

If you’re launching a clothing brand or starting a new collection, understanding the apparel manufacturing process can help you plan better, avoid costly mistakes, and manage your timelines more efficiently.

At [smpl], we guide brands through each step, from concept to final delivery. Here’s a detailed, step-by-step breakdown of the apparel manufacturing process, with estimated timelines for each stage.

✅ Step 1: Tech Pack & Design Finalization (1-2 Weeks)

The process starts with a complete tech pack, which includes:

Flat sketches

Size specifications

Fabric and trim details

Colorways

Label and packaging instructions

The clearer your tech pack, the smoother the production process will be. This is where you confirm all design details with the manufacturer.

✅ Step 2: Material Sourcing (1-3 Weeks)

Once the tech pack is finalized, the factory will source:

Fabrics

Trims (zippers, buttons, labels)

Packaging materials

Lead times for fabric depend on whether it’s in-stock or custom-made. In-stock fabrics can be secured within days, but custom-dyed or woven fabrics may take 2-4 weeks.

✅ Step 3: Sampling (2-4 Weeks)

The sampling phase is critical for ensuring your product matches your vision. This usually includes:

Proto Sample: First physical version

Fit Sample: Checks sizing and fit

Sales Sample: Used for marketing or wholesale pitches

Pre-Production Sample: Final approved version for bulk production

Expect 2-4 weeks per round of sampling, depending on complexity and revisions.

✅ Step 4: Bulk Production (4-12 Weeks)

After the pre-production sample is approved, the factory moves into full production:

Cutting

Sewing

Printing/embroidery

Finishing (labels, trims, pressing)

Timelines depend on:

Order quantity

Garment complexity

Factory capacity

Small batches may take 4-6 weeks, larger orders can take 8-12 weeks.

✅ Step 5: Quality Control (Ongoing + Final Inspection)

Throughout production, most factories conduct:

Inline quality checks (during sewing and finishing)

Final batch inspection (random sampling for defects)

At this stage, the factory ensures the sizing, stitching, and packaging meet your approved standards.

✅ Step 6: Packaging & Shipping (1-3 Weeks)

Once quality control is passed:

Items are packaged according to your branding requirements

Orders are prepared for shipping (sea freight, air freight, or courier)

Shipping timelines vary:

Air freight: ~7-10 days

Sea freight: ~30-45 days

Summary of Estimated Timelines

Stage	Timeline
Tech Pack Finalization	1-2 weeks
Material Sourcing	1-3 weeks
Sampling	2-4 weeks/round
Bulk Production	4-12 weeks
Quality Control	Ongoing
Packaging & Shipping	1-3 weeks
