Buyers in Saudi Arabia, the UAE and Qatar need to know two things before they sign: which standards a cleanroom is built to, and who stands behind the engineering. Pak Gusu manufactures cleanroom panels, doors, pass-through chambers and air-handling components in Lahore, Pakistan, and ships them across the GCC through Jebel Ali, King Abdul Aziz Port (Dammam) and Hamad Port (Doha). Every system we quote is designed to meet the reference standards your regulator and your validation team will measure it against — ISO 14644 cleanliness classes, EU-GMP Annex 1, WHO TRS guidance and, where medical devices are in scope, ISO 13485 quality-management principles.
This page is deliberately precise about credentials. It separates what GUSU Purification (our China technical partner) holds from what Pak Gusu holds, so your QA and regulatory affairs teams can document the supply chain accurately. We do not list certificate numbers we cannot evidence, and we do not claim SFDA approval, MOHAP/DHA licensing or Civil Defence sign-off that we do not have. Instead we tell you which standards we engineer to and how we support your own submission to the relevant authority.
The standards Pak Gusu engineers to
Our cleanroom envelopes and components are designed and documented against internationally recognised standards. We provide the technical data, drawings and test references your validation team needs to demonstrate conformity — the formal classification is achieved on your site, by your validation provider, under your regulator's framework.
- ISO 14644-1/-2: airborne particle cleanliness classes ISO 5 to ISO 8, which cover the majority of pharmaceutical, medical-device and healthcare applications across the GCC.
- EU-GMP Annex 1: Grade A/B environments designed to ISO 5 conditions, Grade C to ISO 7 and Grade D to ISO 8 — the framework SFDA, MOPH and the UAE health authorities expect for sterile and aseptic manufacturing.
- WHO TRS guidance: applied where clients manufacture for tenders and markets that reference WHO good-manufacturing-practice expectations.
- ISO 13485 principles: applied to projects supporting medical-device cleanrooms, so the build aligns with your device quality-management system.
We describe our systems as compliant with and validation-ready for these standards. We do not state that a delivered room is automatically certified; certification follows your commissioning, qualification and validation (CQV) activity on the ground.
GUSU Purification (China): our technical partner's credentials
Pak Gusu is the Pakistan-based manufacturing and regional partner of GUSU Purification in China. GUSU brings decades of cleanroom equipment engineering, established production tooling and a mature quality system to the partnership — an E-E-A-T asset that underpins the consistency of the components we manufacture and supply.
It is important to be exact here: credentials, factory audits and product test data that belong to GUSU are GUSU's, and we present them as the partner's documentation, not as Pak Gusu's own certifications. When your QA team requests partner evidence — material test reports, equipment specifications or factory quality documentation — we route it through GUSU and identify it clearly as such. This separation keeps your supplier-qualification file honest and audit-defensible.
- Partner technical scope: cleanroom equipment design, fan filter units, air showers, pass-through chambers and purification system know-how.
- What this means for you: proven reference designs adapted by Pak Gusu for GCC climate, voltage and shipping conditions.
- What it does not mean: GUSU's credentials are not transferable as Pak Gusu licences or local Gulf approvals.
What Pak Gusu can and cannot claim — read before you tender
We would rather lose a line in a tender than overstate a credential and create a problem at audit. So here is the plain version.
We CAN: manufacture to ISO 14644 and EU-GMP Annex 1 reference conditions; supply technical submittals, drawings and material data for your dossier; offer on-site installation and supervision at extra cost; and support your submission to the relevant authority.
We CANNOT and DO NOT claim: 'SFDA approved', 'GMP certified', 'MOHAP/DHA licensed', 'DCD/Civil Defence approved', or completed projects in a specific Gulf country we have not delivered. Pak Gusu has no Gulf office. Regulatory approval of a facility is granted by the authority — Saudi SFDA, UAE MOHAP, Dubai's DHA, Abu Dhabi's DoH, Dubai Civil Defence, or Qatar's MoPH — to the facility owner, not to a component supplier.
- Use our wording in your documents: 'designed to meet', 'compliant with', 'validation-ready for', 'we support your submission'.
- We will sign technical declarations that match the evidence we can provide — nothing beyond it.
How our documentation supports your GCC submission
A cleanroom only earns its certification once it is built, commissioned and qualified on site. Pak Gusu structures every export project so your validation team and your regulator's reviewer have what they need without chasing the supply chain.
- Design submittals referencing the target ISO 14644 class and EU-GMP grade per room.
- Component data: panel construction, door and window specifications, pass-through interlock logic and finish details suitable for HACCP, GMP and ISO environments.
- Material and partner documentation from GUSU, clearly labelled as partner-issued.
- Installation and supervision (optional, at additional cost) to keep the as-built consistent with the validated design.
This package is what lets your consultant move from a delivered system to a qualified, classified facility under SFDA, MOPH or UAE health-authority oversight.
Shipping, lead times and where certification happens
We export cleanroom systems from Pakistan to the GCC on CIF or DAP Incoterms, depending on what suits your project and your customs broker. Typical destination ports are Jebel Ali for the UAE, King Abdul Aziz Port (Dammam) for Saudi Arabia and Hamad Port for Qatar, with inland delivery to sites in Riyadh, Jeddah, Dubai, Abu Dhabi and Doha arranged as needed.
- Indicative production lead time: roughly 4 to 8 weeks from approved drawings for standard panel-and-door packages; complex turnkey scopes take longer and are confirmed per project.
- Sea transit: commonly around 1 to 3 weeks from Karachi to GCC ports, plus customs clearance handled by your importer of record.
- Certification timing: classification testing and validation occur after installation, on your site — we time our documentation handover to align with your CQV schedule.
Because final certification is a site activity governed by your local authority, planning the shipping and validation windows together is the single biggest factor in hitting your go-live date.

Frequently Asked Questions
Common questions about cleanrooms, standards, cost and how Pak Gusu supplies and installs across the GCC.
Is Pak Gusu SFDA approved or MOHAP/DHA licensed?
No, and we will never claim it. SFDA, MOHAP, DHA and DoH grant approval to the facility owner, not to a component supplier. Pak Gusu manufactures cleanrooms designed to meet ISO 14644 and EU-GMP Annex 1, and we support your submission to the relevant regulator with the technical documentation your validation team needs.
Which cleanroom standards do you build to?
We engineer to ISO 14644-1 cleanliness classes ISO 5 through ISO 8, EU-GMP Annex 1 grades A/B/C/D, WHO good-manufacturing-practice guidance, and ISO 13485 principles for medical-device projects. Our systems are described as compliant with and validation-ready for these standards; formal classification is achieved during commissioning and qualification on your site.
How does the GUSU China partnership affect certification?
GUSU Purification is our China technical partner and supplies proven cleanroom-equipment engineering. Their credentials and test data belong to GUSU and we present them as partner documentation, clearly separated from Pak Gusu's own scope. This keeps your supplier-qualification file accurate and gives your QA team traceable, audit-defensible evidence for the components we manufacture and ship.
Can you provide documentation for our regulatory dossier?
Yes. We supply design submittals referencing the target ISO class and EU-GMP grade per room, component specifications, interlock logic and material data, plus GUSU partner documentation labelled as partner-issued. We time this handover to your CQV schedule so your consultant can move the delivered system through qualification under SFDA, MoPH or UAE health-authority oversight.
Do you install and certify the cleanroom in the Gulf?
We offer on-site installation and supervision at additional cost across the GCC, but Pak Gusu has no Gulf office and does not certify facilities. Classification testing and validation are performed on your site by your validation provider, and the facility approval is issued by your local authority such as SFDA, MOPH or Dubai Civil Defence.
What are your lead times and shipping ports for the GCC?
Standard panel-and-door packages typically take about 4 to 8 weeks from approved drawings, with sea transit of roughly 1 to 3 weeks from Karachi. We ship on CIF or DAP terms to Jebel Ali (UAE), King Abdul Aziz Port Dammam (KSA) and Hamad Port (Qatar), with inland delivery to Riyadh, Dubai, Abu Dhabi and Doha arranged per project.
