Tech Pack for Garment Manufacturing: What Bangladesh Factories Need to Quote and Produce Your Design

What Is a Tech Pack, and Why It Decides Your Orders Success

Here is what a complete tech pack does for your order:

A professional apparel tech pack is not a single page, it is a structured set of pages, each answering a different question the factory will ask. Here is what every complete tech pack should contain.

The two sections where first-time buyers lose the most money are the BOM and the measurement specification, so they deserve a closer look.

The Bill of Materials (BOM)

The Measurement Specification (Points of Measure)

This defines the exact dimensions for every point of measure on the garment, in your base sample size, with a graded chart for the full range. Common POMs include chest width, body length, shoulder width, sleeve length, neck opening, and cuff width. Each entry needs three things: the measurement description, the target value, and an allowable tolerance (the acceptable plus/minus variation). Pair the chart with a POM diagram so the factory measures in exactly the same place you do. Fit is one of the main reasons garments get returned, this section is where you control it.

How to Create a Tech Pack: Tools and Approach

You do not need to be an illustrator or a technical designer to produce a workable tech pack. Here are the realistic routes.

Spreadsheets (Excel / Google Sheets) work well for the BOM, measurements, and costing, accessible and familiar, and perfectly adequate for brands handling a limited number of styles per season.

From two decades of reading tech packs on the Bangladesh side, these are the errors that cause the most expensive problems:

Frequently Asked Questions

What is a tech pack in garment manufacturing?

What should a tech pack include for a Bangladesh factory?

What is the difference between a tech pack and a spec sheet?

A tech pack is a complete, multi-page document covering sketches, materials, measurements, construction, and packaging for a specific garment. A spec sheet usually refers to just the measurement specification within it. For apparel manufacturing you need a full tech pack; a spec sheet alone does not give the factory enough to produce accurately.

How many pages should a tech pack be?

Can a buying house create a tech pack for me?

Yes. An experienced buying house can build a complete, factory-ready tech pack from your design, sketch, or a reference garment. Because the buying house knows exactly what the production floor needs, this typically reduces sampling rounds and produces more accurate quotes than a tech pack made without production knowledge.

Turn Your Design Into a Factory-Ready Tech Pack

A tech pack is not bureaucracy, it is the document that decides whether your order arrives looking like your design or like the factorys guess. The European brands that source successfully from Bangladesh are simply the ones who specify clearly and work with a partner who knows what the production floor needs.

What a garment tech pack should communicate

A garment manufacturing tech pack should help another person understand the intended style without relying on assumptions or verbal context. A useful sourcing conversation begins with the product rather than a broad supplier search. Describe the intended customer, the garment purpose, the construction direction, and the level of finish that matters to the brand. A clear written brief gives every participant the same reference point and makes later comments easier to trace.

Build a brief that can be reviewed

Start with drawings, reference garments, measurement information, colour direction, fabric preferences, trim notes, artwork, packing instructions, and destination-market expectations where they are known. Mark which details are fixed and which are open for discussion. This prevents a preliminary discussion from being mistaken for an approved production instruction.

• Flat sketches and construction callouts
• Measurement chart and tolerances set by the buyer
• Material and trim descriptions
• Artwork, labels, and packing instructions

Use approvals as decision points

Sampling works best when feedback is consolidated by one buyer-side owner. Comments should identify the garment, size, location of the issue, requested change, and whether a new sample is needed. Keep the approved reference, comment history, and current specification together. This creates a practical record for product, quality, and logistics colleagues who join the program later.

Keep communication specific

Ask direct questions about what is confirmed, what remains open, and what requires buyer approval. Avoid treating a mood board or an informal message as a final instruction. When a change affects fabric, fit, branding, packing, or shipment handling, restate the change in writing and keep it with the active product file. Clear handoffs are more useful than long status messages.

Maintain one active style record

A style record is a working reference, not a formal document for its own sake. It can hold the latest sketch, measurements, material direction, artwork, labels, packing notes, and the decision log. Give the file a clear version name, circulate it after a meaningful update, and make sure a buyer-side owner can identify the current approved position. This is particularly helpful when merchandising, design, quality, and logistics are involved at different points.

Separate exploration from instruction

Early product development often involves alternatives. A buyer may compare fabric character, trim options, finishing details, or packaging ideas before choosing one direction. Record these as options until the buyer has made a decision. Once an instruction is approved, restate it in the style record and retire superseded references. This small discipline prevents a previous mood board, image, or message from being used as an unintended instruction.

Prepare the next handoff before it is needed

Before a product moves from development to bulk preparation, review the style record with the people who will use it next. Confirm the approved reference, measurements, artwork, labels, packing notes, and the route for questions. Before shipment handoff, repeat the exercise for buyer-side logistics contacts. The aim is not to add unnecessary meetings. It is to make sure a decision is visible before someone must act on it.

Useful sourcing relationships are built on specific questions and prompt buyer decisions. If information is incomplete, say so and identify who will provide it. If a request has changed, connect the update to the exact style and record the impact on the active brief. That approach gives both sides a calmer way to solve problems and keeps the product discussion grounded in evidence rather than assumption.

Review the product as a connected whole

A garment can look correct in an image while still leaving important questions unanswered. Review construction, measurements, material direction, labels, artwork, packing, and the intended use together. If a reference only shows one part of the garment, note the missing information rather than filling the gap by assumption. A short list of unresolved points is useful when it is attached to the active style file and assigned to the right buyer-side owner.

The same approach applies when several styles belong to one range. Give each style its own record, then keep range-level artwork, packaging direction, and shared buyer contacts in a separate folder. This makes it easier to see whether an instruction applies to every garment or only to one variation. It also gives a new colleague a practical way to understand the programme without relying on a long chain of messages.

Before sending an update, ask whether the recipient can act on it. State the style, the current reference, the decision needed, and the person responsible for that decision. This simple format avoids vague follow-up and creates a useful trail when product work is reviewed later. It also helps buyer teams retain the context behind a final choice.
