Inspiration for your next project

From requirement to accredited report in five steps

Define the requirement

Tell us what you need tested, which standard or buyer program applies (or let us advise), and your deadline. We confirm method coverage, accreditation applicability, and issue a formal quote — typically same business day for standard requests.
Step 1

Submit your sample

Deliver samples to our Karachi or Lahore facility by drop-off or courier. For ZDHC wastewater sampling, ETP audits, or lab development consultancy, we travel to your facility. Sampling guidance is provided upfront so results are not invalidated by improper collection.
Step 2

Accredited Chain Custody

All tests are conducted by qualified analysts under documented procedures using calibrated and maintained equipment. Chain of custody is maintained from receipt to report issuance. ZDHC Gateway tests are run against the current ZDHC Wastewater Guidelines version.
Step 3

Accredited report issuance

You receive an ISO/IEC 17025 accredited test report with full method references, equipment traceability, measurement uncertainty statements where applicable, and result comparisons against the relevant limit table — audit-ready, no additional reformatting required.
Step 4

Debrief & next action

We walk you through what the results mean, including what passed, what failed, what the margin is, and what the corrective action pathway looks like. If a targeted retest is viable before your deadline, we advise you immediately rather than after the fact.
Step 5
We are trusted by thousands of clients

We offer accredited industrial testing services at competitive prices.

Why Pakistan's exporters and manufacturers choose us?

Accredited results. Audit-ready reports. Direct access to the technical team that ran your tests.

ISO/IEC 17025 Accredited

Internationally recognised laboratory competence that is not just claimed but evidenced by our active accreditation. It is accepted by global brand auditors, customs authorities, and regulatory bodies.

ZDHC / GTW Wastewater Testing

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.

Audit-grade reporting

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.

Built for export deadlines

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.

Direct technical access

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.
