In apparel sourcing, quality is decided before production starts — in a document. A tech pack is the complete technical specification of a garment: what it’s made of, how it’s constructed, how it’s measured and what tolerances apply. Factories quote from it, sample against it, and produce to it. Skip it, and every dispute becomes your word against theirs.
Tech Pack Apparel Manufacturing works best when you plan specifications, budgets and quality checks before contacting factories. This guide walks overseas buyers through the process step by step.

What Goes In a Tech Pack
- Technical flat sketches — front, back and detail views, annotated with construction notes.
- Bill of materials (BOM) — fabric composition and weight, thread, elastics, buttons, zippers, labels, hangtags. Specify each by material, grade and supplier standard, not just “cotton elastic.”
- Measurement chart with tolerances — every point of measure (POM), the target dimension, and the acceptable tolerance per size. This single table prevents most fit disputes.
- Size grading rules — how dimensions change between sizes, so your XS and XL are the same design.
- Construction details — stitch types, seam finishes, needle sizes where relevant, reinforcement points.
- Artwork and placement — prints, embroidery, logo position, with dimensions and color references.
- Labeling and packaging — care labels, size labels, country-of-origin marking, polybag and carton specs. Labeling rules vary by market — confirm requirements for your destination before production.
Tolerances: The Line Between Spec and Hope
A measurement chart without tolerances is a wish list. Set realistic tolerances per point of measure — tighter for critical fit points, looser for styling dimensions — and reference them in your inspection criteria. When a pre-shipment inspection measures garments against the chart, tolerance is what turns measurement into a pass/fail judgment.
The Sample Cycle That Follows
Expect rounds: proto sample (design intent), fit sample (on your measurement chart), pre-production sample (final materials, final details — your golden sample). Each round has a purpose; skipping rounds to save time moves the discovery of problems from sampling to mass production. See requesting samples the right way.
Categories Where Tech Packs Matter Most
Intimates and bodywear are the most tolerance-sensitive categories we handle — underwear sourcing succeeds or fails on grading and elastic recovery. The same discipline applies to women’s clothing and any fitted garment.
How We Help
Our team builds tech packs with factories in Chinese, aligns BOMs with what each factory can actually source, and enforces the measurement chart through sampling and inspection. Bring sketches or reference garments and we’ll turn them into a production-ready spec. Contact LIUHAO GLOBAL.
Pro Tips for Tech Pack Apparel Manufacturing
Before you commit to tech pack apparel manufacturing, request samples from at least three verified factories and compare specifications, unit prices and lead times side by side. Keep every quote in writing, including tooling, packaging and payment terms, so nothing changes after the order is placed.
A small trial order protects your cash flow while you test real production quality. For more background on supplier verification, read our sourcing insights, check trade statistics on Trade Map, or contact our team for a tailored sourcing plan for your product category.
Frequently Asked Questions About Tech Pack Apparel Manufacturing
Is tech pack apparel manufacturing realistic for small and mid-size buyers?
Yes. Most suppliers work with tiered MOQs, and working with a China sourcing company like LIUHAO GLOBAL lets you consolidate several product lines into one shipment. Check global trade data on Trade Map to sanity-check demand before you commit.
How do I start tech pack apparel manufacturing?
Start with a shortlist of verified manufacturers, request samples with documented specifications, and only scale up after a pre-shipment inspection. Contact us for a step-by-step plan built around your product category.
