It is the technical blueprint that turns a design concept into a production-ready garment — and the difference between a smooth sample approval and weeks of revisions, missed deadlines, and unexpected costs. For a comprehensive overview, see our [Bangladesh buying house](https://taeen.com.bd/) guide. This 2026 buyer's guide explains what a tech pack is, what sections every apparel tech pack must include, the common mistakes international brands make when sending tech packs to Bangladesh factories, and how a buying house like TAEEN bridges the gap between your design team and the production floor. As a Dhaka-based [buying house](https://taeen.com.bd/ "TAEEN — Premier Buying House in Bangladesh"), TAEEN works with brands every day to turn tech packs into finished garments on time, on spec, and on budget. ## What Is a Tech Pack? A tech pack (short for "technical package" or "technical pack") is a structured document that communicates every detail a factory needs to produce a garment: measurements, materials, construction methods, artwork placement, labeling, and packaging. It is the contract between the brand's design intent and the factory's production output. A complete tech pack typically runs 8 to 30 pages depending on garment complexity. A simple T-shirt might need 6 sections; a fully-lined jacket with embroidery and trims may need 15+ sections, plus separate artwork files and graded size spec sheets. For Bangladesh sourcing specifically, the tech pack serves three roles: - **Communication bridge** between your design team in Europe, the US, or Australia and a factory team that may not share your native language. - **Cost basis** — the factory prices the order from the tech pack. Incomplete tech packs lead to incorrect quotes and surprise costs later. - **Quality reference** — the QC team measures every finished garment against the spec sheets in the tech pack during inline and final inspections. ## Essential Sections of an Apparel Tech Pack A well-structured apparel tech pack for Bangladesh production should contain the following sections. Each section is explained in detail below. ### 1\. Cover Page and Style Summary The cover page identifies the style, season, designer, and revision number. Include: - Style name and number (e.g. "MS-26-014") - Season (e.g. "Autumn/Winter 2026") - Brand name and division - Designer name and contact - Date of issue and revision history - Target factory (if pre-assigned) - Production country (Bangladesh) ### 2\. Technical Sketches (CADs) Flat technical drawings — front view, back view, side view, and detailed close-ups of collars, cuffs, pockets, plackets, and any unusual construction. These should be vector CADs (Illustrator or CLO 3D), not photographs. Bangladesh factories are highly experienced at reading CADs and prefer them over photo references for measurement work. Every CAD should include: - Clean line work in black on white - Stitch lines, seam allowances, and topstitching positions - Notches, drill holes, and gathering marks - Construction callouts with reference letters and numbers - Artwork placement guides ### 3\. Bill of Materials (BOM) The BOM is the complete list of every material required to make one garment. It is the basis for fabric and trim sourcing, costing, and inventory planning. A complete BOM includes: - Shell fabric (composition, weight in gsm, width, finish, color, supplier reference) - Lining fabric - Interfacing and fusible components - Trims: buttons, zippers, snaps, drawcords, elastic, twill tape, labels, care labels, hang tags - Thread (polyester or cotton, Tex weight, color references) - Packaging materials: polybags, tissue, stickers, cartons For each BOM item, specify the supplier reference, color (Pantone TPX), and unit consumption (how much per garment). A 200gsm single jersey T-shirt, for example, uses roughly 180–220 grams of fabric per garment. ### 4\. Colorway List A colorway sheet lists every color combination you intend to produce. For each colorway, the factory needs: - Color name and code - Body fabric color - Trim color combinations (buttons, zipper tape, thread, labels) - Pantone TPX or TCX reference for each color - Lab dip approval status Bangladesh mills and dyehouses use Pantone TPX for fabric color matching. Always specify TPX, not coated or uncoated Pantone C/U (which is for print). ### 5\. Measurement Spec Sheet (Size Spec) The measurement spec is the single most critical page in any tech pack. It lists every measurement of the finished garment — body length, chest width, sleeve length, hem width, and so on — at each size point (XS, S, M, L, XL, XXL). Best practice for Bangladesh production: - Specify measurements in centimetres (cm) — most Bangladesh factories work in cm by default. - List every Point of Measure (POM) with a code (POM 1, POM 2, ...) and a reference image showing where it is measured. - Include tolerances for each measurement (typically ±0.5cm or ±1cm depending on the measurement). - Specify the measurement method (garment flat, body, or stretched). - Include a grade rule for each size (e.g. "Chest: +4cm per size"). ### 6\. Grading Sheet Grading is the mathematical rule that determines how each size differs from the base size (usually M). Without grading rules, the factory cannot produce a full size run. For each POM, specify the increment between sizes. A standard T-shirt might grade chest +4cm, body length +1.5cm, and sleeve length +1cm across sizes. ### 7\. Construction Details This section explains how the garment is put together — the techniques and seam types used at every step. Common construction details for Bangladesh production: - Seam type (e.g. 5-thread overlock, 4-thread overlock, lockstitch, coverstitch, flatlock) - Stitch density (stitches per inch or cm) - Seam allowance (typically 1cm for most Bangladesh production) - Topstitch position and thread - Hem type (fold and stitch, blind hem, coverstitch) - Bar tacks at stress points - Buttonhole and button spacing ### 8\. Artwork and Print Placement For printed, embroidered, or appliquéd garments, supply high-resolution artwork files (AI, EPS, or PNG at 300 DPI minimum) and a placement guide showing: - Position relative to body landmarks (e.g. "8cm below shoulder seam, centred") - Size (width x height in cm) - Color references (Pantone TPX for print, thread color codes for embroidery) - Application method (screen print, DTG, sublimation, embroidery, heat transfer) ### 9\. Label and Packaging Specifications Specify every label requirement clearly: - Main label (brand label, position, size, material) - Care label (fibre content, wash instructions, country of origin, RN or WPN number) - Size label (position, color coding per size) - Hang tag (with bar code, price, style number) - Polybag specifications (size, thickness, printed warnings, hang hole position) - Carton markings (style, color, size ratio, carton weight, dimensions) For Bangladesh export, the country of origin "Made in Bangladesh" is mandatory on the care label by international labelling law. ### 10\. Care Label Content The care label is a regulatory requirement in most markets. Bangladesh factories need: - Fibre composition (e.g. "100% Cotton" or "60% Cotton, 40% Polyester") - Wash symbols (ISO or ASTM standard, depending on destination market) - Country of origin - RN number (US), WPN (Canada), or EU Responsible Person details - Batch or lot reference ## Tech Pack Examples by Product Type Different garments need different levels of detail. Here is what changes based on product type. ### T-shirts and basic knit tops The simplest tech packs. 6 to 8 sections, basic measurements, single fabric, minimal trims. Most Bangladesh factories have standard templates they can share with brands. ### Denim jeans and jackets More complex. Add washing specification (enzyme wash, stone wash, acid wash, rinse), shade band approval process, rivets and reinforcement, and detailed measurements at multiple wash stages since denim shrinks. ### Fashion outerwear The most complex. Include lining, interlining, padding, zip specification, snap and button specifications, hood construction, drawcords, cuffs, seam taping, and water-repellency test requirements. ### Activewear and swimwear Add stretch and recovery requirements, UV protection specifications, chlorine and salt water resistance, and specific stitching requirements (often flatlock or coverstitch). ## Common Tech Pack Mistakes International Buyers Make Even experienced brands make these mistakes when sending tech packs to Bangladesh factories. Avoiding them saves weeks of back-and-forth and prevents costly errors. ### 1\. Sending photo references instead of CADs Photos don't communicate measurements, seam allowances, or construction details. CADs are required for production. Photos can be included as mood references but should never replace technical drawings. ### 2\. Missing Pantone references "Navy blue" means different things to different factories. Always specify Pantone TPX or send a physical swatch for lab dip approval. ### 3\. No tolerances Without tolerances, factories either reject measurements as impossible or interpret them differently than you intend. Specify acceptable variance for every measurement. ### 4\. Mixing units Inches in one section and centimetres in another confuses everyone. Pick one unit system and stick to it. For Bangladesh, centimetres are standard. ### 5\. Incomplete BOM A BOM without thread, labels, or packaging materials leads to surprise costs and production delays. Include everything the factory needs to produce one finished garment in the export carton. ### 6\. No grade rule Without grading specifications, the factory cannot produce a full size run. Always include a grade sheet or graded spec alongside the base spec sheet. ### 7\. Skipping the measurement diagram A measurement table without a diagram showing where each POM is taken leads to inconsistent measurements between samples and across size runs. ### 8\. Not specifying testing requirements If your destination market requires specific tests (e.g. CPSIA for US children's wear, REACH for the EU), spell them out in the tech pack. Testing adds cost and lead time — it should not be discovered after sampling. ## From Tech Pack to Sample: The Handoff Process Once your tech pack is complete, the typical Bangladesh sample development timeline runs as follows. 1. **Counter sample (CS)** — 7 to 14 working days. Initial sample made from available materials to verify construction and fit direction. 2. **Fit sample (FS)** — 7 to 14 working days. Refined sample on actual production fabric, fitted on a model, with measurement report. 3. **Pre-production sample (PP)** — 7 to 14 working days. Made on the exact production line, with all approved trims and lab dips. 4. **Top of production sample (TOP)** — taken from the first bulk shipment batch. Final reference for the QC team. A well-prepared tech pack typically reduces the CS to FS cycle by 30 to 50 percent because the factory has fewer clarifying questions to resolve. ## The Tech Pack Revision Cycle Tech packs are living documents. Each sample round typically produces a revision with changes marked in red. Best practice: - Use clear revision numbers (Rev 0, Rev 1, Rev 2, ...) - Highlight changes from the previous version - Send a revision summary email with each new version - Get written confirmation of the latest revision before production Bangladesh factories typically keep a sample room log of every revision sent for a style. This is helpful when you reorder the same style months later. ## Cost and Time Impact of a Quality Tech Pack The investment in a quality tech pack pays back many times over: - Reduces sample rounds from 4 to 5 down to 2 to 3 (saving 2 to 4 weeks of lead time) - Reduces material waste during production (better costing accuracy) - Reduces QC disputes (clear spec reference) - Reduces post-production rejections A tech pack prepared by an experienced product developer or buying house typically costs USD 150 to 500 per style depending on complexity. For a Bangladesh order worth USD 20,000 or more, this is a tiny fraction of total order value — and it saves many times its cost in avoided errors. ## Tech Pack Checklist for Bangladesh Production Use this checklist before sending your tech pack to a Bangladesh factory: - Cover page with style number, season, revision history - Front, back, side technical CADs with construction callouts - Complete BOM with supplier references and Pantone TPX colors - Colorway sheet with Pantone references - Measurement spec sheet with all POMs, tolerances, and a measurement diagram - Grading sheet for the full size run - Construction details (seam type, stitch density, seam allowance) - Artwork files at 300 DPI minimum, with placement guides - Label specifications (main, care, size, hang tag) - Polybag and carton specifications - Testing requirements for the destination market - Care label content (fibre, wash symbols, country of origin) ## How TAEEN Helps With Tech Packs As a full-service buying house in Bangladesh, TAEEN supports brands at every stage of the tech pack process: - **Tech pack review** — our team reviews incoming tech packs for completeness and Bangladesh-specific requirements before sending to factories. - **Tech pack preparation** — for brands without an in-house product developer, we can prepare tech packs from reference samples, sketches, or photos. - **Sample coordination** — our [product development and sampling service](https://taeen.com.bd/services#product-development-sampling "Product Development and Sampling service") manages the full counter sample to fit sample to PP sample to TOP sample cycle. - **QC against tech pack** — our QC team uses the tech pack spec sheet for every inline and final inspection.
