Buying denim waste in Bangladesh
Denim waste is the cuttings left in jeans factories and the fabric ends and yarn waste left in denim mills. Denim fabric is a large Bangladeshi export, so its mills and jeans factories generate both. Recyclers shred the waste into fibre for new yarn, felt, insulation, filling and low-end blankets.
Elastane and dye decide what denim fibre can become, so a denim waste exporter in Bangladesh has to sort before it bales. Roptan sources from verified sellers, writes rigid or stretch, the elastane limit, dye family and shade into the order, has every lot tested, then delivers or ships it. You deal with Roptan only.
Briefing a denim waste exporter in Bangladesh
- Rigid or stretch
- Which you want, or the share of each, packed in separately marked bales.
- Elastane limit
- A maximum in percent by weight, measured on opened bales, so a stretch sort cannot pass as rigid.
- Dye and shade
- Indigo or sulphur-dyed, then the shade groups you accept, each matched to a reference sample.
- Source
- Jeans factory cuttings, denim mill fabric ends or mill yarn waste. Each is a different product and may go on a different tariff line.
- End use
- Yarn, felt, insulation or filling, so the sort and the elastane limit fit the route the fibre will take.
Tests and codes for denim waste
- ISO 1833-20
- The chemical method for fibre mixtures containing elastane. A report on bales from your lot shows whether a rigid sort is elastane-free and how much a stretch sort carries.
- HS 6310 and HS 5202.10
- Denim cuttings usually go under heading 6310 for rags and scrap textiles, and denim yarn waste under 5202.10 for cotton yarn waste. The broker confirms each line.
- GRS, RCS and the Materials Matter Standard
- GRS and RCS both take pre-consumer material such as denim cuttings, with a 50 percent recycled content floor under GRS. The Materials Matter Standard, effective 31 December 2026, is replacing both, with claims and labels following it from 30 June 2029.
Lead times and delivery
Denim waste follows the output of jeans factories and denim mills. A rigid-only lot or a single shade group usually takes longer to gather than mixed denim, as enough of it has to be gathered to fill your load, and an elastane test adds time. Your quote from Roptan confirms the dates and any minimum.
Inside Bangladesh we deliver denim waste in bales marked rigid or stretch and by shade group, dry and covered, to your recycling, felt or spinning mill, with the packing list by bale, the elastane test report and a VAT invoice (Mushak 6.3).
Buying denim waste for export
We quote FOB Chattogram (Chittagong). No textile waste is prohibited or conditional under the Export Policy 2024-27, though the government can still prohibit an export temporarily, and the exporter must hold a valid ERC issued by the CCI&E. Textile waste is also on the Basel Convention parties' work programme for 2026 and 2027, and your country's own permits apply. Before quoting, Roptan confirms whether any minimum export value applies.
Questions buyers ask
Can stretch denim waste be recycled into yarn?
It depends on the elastane share and the recycler's line. Stretch denim carries up to about 3 percent elastane, and around 5 percent usually rules fabric out of most mechanical recycling machines, so the margin is small. Test the elastane share, keep stretch apart from rigid, and agree with your recycler what share its line accepts.
What is recycled denim fibre used for?
Shredded denim fibre goes into stuffing, automotive components, carpet underlay, insulation, roofing felt and low-end blankets. Recycled cotton is shorter, so in yarn it is usually blended with a carrier fibre, at about 20 percent in ring yarn; open-end spinning copes better with short fibre in coarser counts.
Why sort indigo denim from black denim?
Because the dyes differ. Indigo gives the traditional blues, while sulphur dyes give black, grey, rust, mustard and green. Recyclers sort by fibre and then by colour so that the fibre needs no re-dyeing, and a lot sorted by dye family and shade can go into more products.
Do you supply denim yarn waste as well as cuttings?
Yes, from denim mills. Yarn waste is a different product from fabric cuttings and is usually declared as cotton yarn waste, not as rags, so order it as its own line, with the count (Ne), colour and cotton share stated.
How soon will I hear back about textile waste and rags?
Within 48 hours of a complete requirement, with a price and a delivery date. A requirement is complete when it has the quantity, where it is needed and by when.
