Custom Sportswear and Activewear Manufacturer in Bangladesh: OEM Process From Tech Pack to Bulk

A custom sportswear and activewear manufacturer in Bangladesh makes leggings, shorts, tops, tracksuits and training sets to your own specification, under your own label. That is an OEM order: the factory works from your tech pack, your fabric and your artwork, and the bulk repeats the samples you approved in writing. This guide runs the process from tech pack to bulk, so you know what to send, what to ask and where orders go wrong.

The Bangladesh Knitwear Manufacturers and Exporters Association (BKMEA), established in 1996, is the apex trade body for the knitwear sector and represents approximately 2,540 knitwear member factories.¹ Many sportswear and activewear styles are knitted, so knitwear factories are a natural starting point, alongside woven garment factories for styles cut from woven fabric.

Why this matters for buyers and sellers

What should I know first about sportswear and activewear?

Know first that a custom order is priced and scheduled against one specification. The same legging in a different fabric weight, a different print method or a different size range is a different order, with a different minimum, price and production plan. Buyers who send one complete tech pack to every candidate get comparable replies. Buyers who send a photo and a target price get replies that cannot be compared, because each factory has priced a different garment.

Classification is part of that specification. In the Harmonized System, heading 6112 covers track suits, ski suits and swimwear, knitted or crocheted, with subheadings split by fibre, including track suits of cotton and of synthetic fibres.² Other sportswear styles sit under other headings, so record the heading agreed for each style and keep it consistent across the quotation, invoice and export declaration. See the HS code for sportswear and activewear guide.

For the buyer, the OEM route gives control over fabric, fit, colors and branding, in exchange for sampling work and a minimum per style and per color. For the seller, the order uses inputs bought or dyed for your specification, so the factory protects that commitment through its minimums and sampling charges. Both sides gain from the same discipline: one specification, written approvals and an inspection plan agreed before bulk starts.

If you sell into the European Union, fibre labelling is fixed early, at the tech pack stage. Regulation (EU) No 1007/2011 states that a textile product shall be labelled or marked with the name and percentage by weight of all constituent fibres in descending order.³ The composition on your care label therefore has to match the fabric you actually approved, not an earlier fabric option.

Step-by-step: how it works

1. Send one tech pack to every candidate. State the style, fabric composition, construction and weight, size chart and grading, construction and stitch details, artwork files with method, size and placement, trims, labels, and packing. A tech pack that leaves fabric or artwork open cannot be costed as a custom order.

2. Nominate the fabric, or ask for options in writing. State whether the factory sources the fabric or you nominate it, and record composition, weight and finish for each option. Ask which colors are stocked and which are dyed to order, because that answer drives the minimum per color.

3. Agree the customisation list. Record each custom element separately: print, embroidery or heat transfer for logos, custom elastic, drawcords and zips, reflective or branded trims, woven labels, hang tags and carton marks. Each element carries its own set-up or run minimum.

4. Approve the proto sample. The first sample tests pattern, fit and construction. Measure it against your size chart and return corrections in writing, with photos where a measurement or placement is wrong.

5. Approve the pre-production sample in the actual fabric. This sample repeats your fabric, color, artwork, trims and labels. Check hand feel and stretch recovery, artwork placement, stitching, measurements and label content against the tech pack, then approve or list corrections in writing.

6. Confirm the order with the minimums stated. The purchase order records quantity per style, per color and per size, the unit price, set-up charges as separate lines, the delivery term and the inspection plan. Do not confirm on a total quantity alone.

7. Follow bulk through inline and final inspection. Ask for an inline check while production is running, so a placement or measurement fault is caught before the order is finished, then a final inspection on the packed goods before shipment.

Example figures: a buyer plans 1,200 pieces across two styles at 600 pieces per style, split across three colors at 400 pieces per color, with one size ratio stated per color. The total, the per-style split and the per-color split all add to the same 1,200 pieces. If a factory sets its minimum per color above 400 pieces, the order clears the total and still fails the per-color line, and the fix is structural: fewer colors, or a larger order. The example shows the structure only, not a typical minimum, price or lead time.

See the sportswear and activewear MOQ guide for how those minimums are set, and the sportswear and activewear manufacturers guide for how factory types differ.

Costs, timelines and documents

What are the typical costs and timelines?

There are no typical costs or timelines a guide can state as fact for a custom order. Each factory prices your fabric, construction, artwork method, trim and label runs, finishing and packing, and the delivery term you choose. Sampling charges, print or embroidery set-up and label runs are fixed costs for the order, so ask for them itemized apart from the unit price. That split is what makes a smaller order negotiable: a set-up paid as its own line does not need to be recovered inside the unit price.

Compare quotations only on the same specification and the same delivery term. The Incoterms 2020 rules set out 11 rules with a clear allocation of cost, risk and obligations.⁴ A lower unit price on a different term, a lighter fabric or stock labels is a different offer, not a saving.

For timelines, ask for each stage as its own line: fabric ready, proto sample, pre-production sample, bulk production, inspection and shipment. Sampling depends on fabric availability and correction rounds, and bulk on dyeing, trim delivery and line capacity.

Example figures: a quotation for 1,200 pieces lists the unit price for those 1,200 pieces, plus separate lines for the sample rounds, one print set-up per placement and one label run. The order total before freight is 1,200 times the unit price, plus the sample, set-up and label lines added once each. The example shows the arithmetic only, not a typical price.

Which documents are needed?

The order documents are the tech pack, the itemized quotation and the purchase order, with the approved sample record attached. For export clearance in Bangladesh, goods may not be loaded unless an export declaration, the Bill of Export or Shipping Bill, is submitted to Customs and approved.⁵ Enclosed documents include the export contract or purchase order where there is no export letter of credit, the commercial invoice, the packing list, the EXP form certified by an authorized dealer, and a certificate of origin issued by the EPB or a Chamber of Commerce and Industry.⁵

Bangladesh-specific rules and tips

Confirm association claims at the source. If a supplier claims BKMEA membership, confirm it with the association itself. BKMEA represents the knitwear sector and its member factories,¹ and it addresses environmental and labour standard issues in its member factories.¹ Membership signals an active knitwear business. It does not confirm that a factory makes sportswear, holds your fabric, or can meet your minimum and dates.

Match the factory type to the product type. Knitwear factories work in knitted fabric, which covers many leggings, tops and tracksuits. A woven style needs a factory set up for that construction. Ask which stages are in-house and which are subcontracted, because a subcontracted print or embroidery stage sets its own schedule.

Keep one legal name across every paper. The export declaration names the exporter and the foreign buyer,⁵ so the name on the trade licence, quotation, proforma invoice and payment account should match. A name that differs between documents is a common cause of avoidable clearance queries.

Agree the inspection standard before production. ISO 2859-1 defines a system of acceptance sampling plans for inspection by attributes, indexed by acceptance quality limit (AQL) for lot-by-lot inspection.⁶ AQL is the maximum average percentage of defective items considered acceptable during random sampling, and it determines sample sizes and acceptance or rejection thresholds.⁶ Write the inspection level and AQL values for measurements, workmanship and packing into the purchase order. See the sportswear and activewear quality control checklist for the product points to check.

Mistakes and red flags

What are the most common mistakes?

Sending a photo instead of a tech pack. A photo carries no fabric weight, size grading or stitch specification. Every factory fills those gaps differently, so the cheapest reply may price a lighter, simpler garment than the one you want.

Approving the proto and skipping the pre-production sample. The proto tests the pattern, often in a substitute fabric. The pre-production sample is the only check of your actual fabric, color, artwork and labels together. Bulk should not start without that approval in writing.

Changing fabric or artwork after costing. A new fabric, a new print placement or an added color restarts dyeing, set-up and sampling. Expect the quotation and the minimums to change with it, and get the revised figures in writing before you accept them.

Comparing prices on different terms or specifications. Compare only replies to the same tech pack on the same Incoterm.⁴ Record fabric weight and composition beside every price, so a lower price on a lighter fabric is visible as a different offer.

Treating a profile or a badge as verification. A profile is a starting point for enquiries. It does not test whether a factory can make your style, and a badge is not a guarantee of capacity, quality or delivery.⁷

Removing inspection to protect a date. Sampling under ISO 2859-1 checks a lot against an agreed AQL,⁶ and the final inspection is the last control before packed goods become your stock. Shorten a correction round instead of dropping the inspection.

How Exportain helps

On Exportain, browse suppliers and post a request for quotation (RFQ) on the RFQ board with your tech pack summary, split per style and per color, customisation list and delivery term, so manufacturers quote against the same specification. Ask each reply for its minimum per style and per color and its set-up lines. When you accept a quotation, Exportain creates one order and issues one proforma invoice from the accepted terms.⁷

Read the badges for what they record. Exportain Verified means Exportain has checked identity, phone, email and business registration, and Export Verified means it has checked the Export Registration Certificate (ERC).⁷ Factory Verified means it has reviewed photos of the manufacturer factory, while Trading Company Verified means it has reviewed photos of the trading company office or warehouse.⁷ Verification is a document review by staff, free, and never granted by membership plans.⁸ It is not a factory inspection,^{7 8} so tech pack approval, sampling and inspection stay with you. See how supplier verification works on Exportain and the private label sportswear and activewear guide if your order carries your own brand.

FAQs

What should I know first about sportswear and activewear?

Know first that a custom OEM order is made to your tech pack, so the specification decides the minimum, the price and the schedule. Send the same tech pack to every candidate, with fabric, sizes, artwork, trims and labels stated, and ask for the minimum per style and per color. Knitted track suits sit under HS heading 6112, split by fibre.²

What are the typical costs and timelines?

There are no typical figures a buyer can rely on, because each factory prices your fabric, construction, artwork, trims and delivery term,⁴ and sets its own minimum per style and per color. Ask for sampling, set-up and label costs itemized apart from the unit price, and for fabric, sampling, production and inspection dates as separate lines.

Which documents are needed?

The order documents are the tech pack, itemized quotation, purchase order and written sample approvals. The export set is the Bill of Export, commercial invoice, packing list, EXP form certified by an authorized dealer, and a certificate of origin issued by the EPB or a Chamber of Commerce and Industry.⁵

What are the most common mistakes?

The most common mistakes are sending a photo instead of a tech pack, skipping the pre-production sample in the actual fabric, changing fabric or artwork after costing, and comparing prices on different specifications or terms.⁴ Reading a badge as a guarantee is another: a badge is not a guarantee of capacity, quality or delivery.⁷
