The cotton T-shirt is the highest-volume item in the US private label apparel market. Whether you are building a DTC basics brand, supplying branded merchandise to corporations, or sourcing blanks for a print-on-demand fulfilment partner, Pakistan is a credible production origin for cotton T-shirts at scale.
This guide covers every stage of the sourcing decision: fabric specification, certifications, printing and labelling, regulatory compliance, and the sample-to-production timeline.
Fabric Weight Selection: 150, 160, and 180 GSM
Fabric weight is the most consequential specification in a T-shirt programme. It determines hand feel, drape, durability, printability, and the retail price point the garment can credibly support.
| GSM | Feel | Best Use Case | Retail Price Point | |---|---|---|---| | 140–155 GSM | Lightweight, semi-sheer | Fashion basics, event tees, giveaways | $8–$20 | | 160–170 GSM | Mid-weight, balanced | Core basics, everyday retail, online DTC | $18–$35 | | 175–185 GSM | Substantial, opaque | Premium basics, retail staples | $28–$55 | | 190–210 GSM | Heavyweight, structured | Streetwear, premium fashion, boxy fit | $45–$100+ |
The cotton T-shirt at 180 GSM represents the most commonly ordered weight for US retail programmes — heavy enough to feel premium but not so heavy as to price out of a competitive mid-market bracket.
For brands whose retail customers benchmark against established US basics brands (which typically run 160–180 GSM), matching or slightly exceeding that weight builds consumer confidence at point of purchase.
Combed vs Carded Cotton
Carded cotton: The standard ring-spinning process that removes most short fibres but does not achieve the alignment and extra cleaning step of combing. Results in a slightly loftier, softer hand with a characteristic texture. More economical to produce.
Combed cotton: Passes through an additional combing step that removes shorter fibres (noils) and aligns the remaining long fibres parallel to the yarn axis. The result is a smoother, stronger, more even yarn with better pilling resistance. Combed ring-spun is the standard for premium T-shirt programmes and is distinguishable by a noticeably smoother surface, better colour depth, and superior print adhesion.
Open-end (OE) spun: A faster, less expensive spinning method producing a bulkier, rougher yarn. Common in lower-price commodity tees. Not recommended for branded programmes at retail.
For a brand selling at $25 or above, combed ring-spun cotton is the correct specification. The single jersey 160 GSM combed fabric available from Meridian is produced from combed ring-spun yarn and serves as the base for the cotton T-shirt programme.
GOTS Organic Cotton Option
For US brands targeting the natural/organic consumer, GOTS (Global Organic Textile Standard) certification on T-shirts requires that:
- The cotton fibre is certified organic (to USDA NOP or equivalent standard)
- All processing stages (spinning, knitting, dyeing, finishing, cut-and-make) are covered by a valid GOTS certificate
- The brand uses a GOTS-licensed label
Pakistan has GOTS-certified facilities across the spinning, fabric, and garment stages. The GOTS organic cotton jersey 160 GSM is available for brands requiring certified organic fibre content. Organic cotton typically carries a 15–30% fabric price premium over conventional cotton at equivalent specifications.
GOTS certification for the finished garment requires the entire supply chain to be GOTS-certified, including the cut-and-make facility. Confirm this with your supplier before quoting organic pricing to your retail customers.
Printing and Labelling
Screen Printing on T-Shirts
Water-based and plastisol screen printing are both widely available in Pakistan's garment export sector. Discharge printing — which chemically removes the dye from the shirt to create the print rather than printing on top of the fabric — is the premium option for on-tone and vintage-effect prints on 100% cotton shirts. It produces a print that is essentially part of the fabric, with a very soft hand.
Note: discharge printing is only effective on 100% cotton reactive-dyed shirts. It does not work on polyester or CVC blends.
Woven Neck Labels and Care Labels
All garments imported into the US for retail sale must bear a permanent care label per FTC Care Labeling Rule (16 CFR Part 423), which requires fibre content, country of origin, and care instructions. Your tech pack should specify the woven label layout and position.
For brands also supplying to the EU market, EU Regulation 1007/2011 has equivalent fibre content labelling requirements with some specific differences in terminology.
Heat-Transfer Labels and Tagless Options
Tagless label printing (screen-printed interior neck label) is a widely available option for brands that want a cleaner retail presentation. Heat transfer care labels are also available. Both require digital artwork files (vector preferred) and one-time setup; confirm the minimum order quantity at which the supplier can offer these economically.
Testing Requirements
CPSIA (Children's Products)
If your T-shirts are sized for children (up to size 16 or age 12), they are subject to the Consumer Product Safety Improvement Act (CPSIA). Key requirements include:
- Lead content: ≤100 ppm in surface coatings, ≤100 ppm total lead in substrate
- Phthalates: ≤1,000 ppm in applicable components
- Tracking label on garment and packaging
- Children's Product Certificate (CPC) based on accredited third-party test reports
Testing must be performed by a CPSC-accepted third-party laboratory. Key labs with Pakistan operations or accepted in the US: SGS, Intertek, Bureau Veritas, and QIMA.
REACH (EU Market)
For brands also selling in Europe, EU REACH Regulation restricts certain hazardous substances in textile articles, including azo dyes, nickel, formaldehyde, and flame retardants. OEKO-TEX Standard 100 certification covers most REACH-relevant restricted substances for apparel and is the practical compliance shortcut for most exporters.
Flammability
16 CFR Part 1610 (general apparel) and 16 CFR Part 1615/1616 (children's sleepwear) apply in the US market. Standard cotton T-shirts in 160–180 GSM meet the Class 1 flammability requirement under Part 1610 without treatment. Children's sleepwear has more stringent requirements — confirm with your compliance team if your T-shirt overlaps with sleepwear use claims.
Sample Process and Lead Times
| Stage | Typical Timeline | |---|---| | Proto sample (fit evaluation, no branding) | 10–14 business days | | Revised proto / fit approval | 5–10 business days | | Sealed sample (production-representative) | 10–15 business days | | Bulk production (post-deposit) | 35–50 days | | Ex-factory to US (sea freight, West Coast) | +20–25 days |
Communicate your season calendar to your supplier at the start of development. Back-planning from your in-store date should account for the full timeline above plus 2–3 weeks buffer for customs clearance and domestic freight.
