SAB Labs is an ISO/IEC 17025 accredited industrial testing and compliance laboratory with certified facilities in Karachi and Lahore. We serve factories, manufacturers, and exporters that need technically credible results to satisfy international brand auditors, customs clearance requirements, and regulatory inspectors without follow-up questions.
Our scope covers textiles and apparel, leather and footwear, ZDHC Gateway wastewater, heavy metals and RSL screening, water and environmental analysis, packaging, polymers, and industrial materials. Most businesses come to us because a major brand has flagged a compliance gap, incoming materials are failing QC, or an export market requires certified third-party documentation.

One of a limited number of laboratories in Pakistan equipped to issue ZDHC Gateway-aligned wastewater reports, which are essential for wet-processing factories in H&M, Nike, Adidas, Inditex, and PVH supply chains.
Reports are structured for direct use in H&M Supplier Portal submissions, Nike NRSS documentation, Walmart supplier audits, and Inditex environmental compliance packages with no reformatting required.
A shipment on hold costs money by the day. We offer express turnaround options for critical pre-shipment compliance testing with direct technical communication, ensuring no queues or holding systems.
When results require interpretation or a non-conformance needs to be understood before it reaches a buyer, you speak directly to the analysts who ran your tests instead of a client services relay.
