SAB Labs is Pakistan's leading ISO-certified wool testing laboratory in Karachi. We provide accurate fiber composition analysis, tensile strength, shrinkage, RSL compliance, and color fastness testing for textile exporters and manufacturers. Our results are accepted by international buyers worldwide — including suppliers of H&M, Primark, and Marks & Spencer.
Wool testing is the scientific analysis of wool fiber properties — from chemical composition to physical performance. For Pakistani textile exporters and manufacturers, it is not optional. It is a legal and commercial requirement for accessing international markets.
Without certified wool test reports, your shipment can be rejected at customs, your buyer can cancel the order, and you can face financial penalties. International brands like H&M, Primark, Marks & Spencer, and Zara all require RSL-compliant test certificates before accepting wool-based products from their suppliers.
SAB Labs, as an IWTO and ISO-aligned wool testing lab in Karachi, Pakistan, provides the certifications your business needs to access EU, US, and Middle Eastern markets with complete confidence.
International buyers require ISO-certified test reports before accepting wool shipments. SAB Labs reports are accepted by EU, US, and Gulf market buyers without question.
RSL testing ensures your wool products are free from harmful chemicals — a strict requirement for brands like H&M, Primark, and Marks & Spencer. Failure to comply results in shipment rejection and order cancellation.
Regular wool testing protects your brand from quality disputes, customer complaints, and costly product recalls. Know what you are selling before your buyer does.
TDAP export programs and government tenders require third-party lab certification for textile materials including wool and blended fabrics. SAB Labs reports are recognized for these submissions.

Everything you need to know before submitting your wool samples to our lab.
Wool testing is the laboratory analysis of wool fibers to verify composition, physical properties, chemical safety, and performance. In Pakistan, it is required because: (1) International buyers mandate test certificates before accepting shipments, (2) EU REACH regulations require chemical compliance, and (3) TDAP export programs require third-party lab certification. Without a certified report from an ISO-accredited lab like SAB Labs, your export order may be rejected.
Standard wool testing at SAB Labs takes 5 to 7 working days from the date of sample receipt. For urgent shipments, expedited testing is available in 2 to 3 working days upon request. Reports are delivered by email in PDF format with a unique reference number.
