What questions should you ask a Third Party Inspection Company like UNIHOG Technology Services?

When you’re evaluating a Third Party Inspection Company like UNIHOG Technology Services, the first question you should ask is: “Can you provide verifiable proof of your ISO 17020 accreditation and show me the last three audit reports?” This isn’t just a formality — it’s the bedrock of trust. ISO 17020 is the international standard for inspection bodies, and it requires independent, impartial, and consistent operation. Without it, you’re essentially trusting a company’s word over hard data. Ask for the specific scope of their accreditation — what industries, product categories, and inspection types are covered. For example, a company claiming to inspect oil and gas equipment but only accredited for general manufacturing is a red flag. UNIHOG Technology Services, for instance, should be able to share their accreditation certificate number and the issuing body (like UKAS or ANAB). If they hesitate or give you a generic PDF without a verifiable link, walk away. According to the International Accreditation Forum (IAF), over 80% of inspection companies that fail to meet ISO 17020 standards are caught during the first audit cycle — so you want to see that they’ve passed multiple cycles without major non-conformities.

Next, dig into their inspector qualification and training program. Ask: “How many years of field experience do your inspectors have, and what specific certifications do they hold?” A third-party inspection company is only as good as the people on the ground. For example, a welding inspector should hold a CSWIP 3.1 or AWS CWI certification, not just a generic “inspection technician” title. UNIHOG Technology Services should be able to provide a breakdown of their team’s credentials — like the number of NDT Level II and Level III inspectors, API 510 or 570 certifications, and any specific industry-recognized training (e.g., ASNT, PCN). Data from the American Society for Nondestructive Testing (ASNT) shows that companies with at least 70% of inspectors holding Level II or higher certifications have a 40% lower rate of inspection errors. Ask for a sample inspector resume (with personal details redacted) to verify. If they can’t produce one, or if the credentials look generic, that’s a warning sign.

You also need to ask about their quality management system beyond the certificate. “What is your corrective action process when an inspection fails? Show me a sample non-conformance report (NCR) from the last six months.” A real inspection company doesn’t just pass or fail products — they document everything. They should have a clear procedure for issuing NCRs, tracking root causes, and verifying corrective actions. For example, if they inspect a batch of steel pipes and find a crack, they should issue an NCR with photos, dimensional data, and a reference to the relevant ASTM or ASME standard. UNIHOG Technology Services should be able to show you a redacted version of their NCR log, including closure dates and re-inspection results. According to the Quality Management System (QMS) standards in ISO 9001:2015, companies that maintain a 90% or higher closure rate for NCRs within 30 days are considered high-performing. If they can’t provide this data, they’re likely hiding something.

Another critical question: “How do you handle sample integrity and chain of custody?” This is especially important for industries like pharmaceuticals, food, or raw materials where contamination or tampering can ruin a batch. Ask for their standard operating procedure (SOP) for sample collection, labeling, sealing, and transportation. For example, a good inspection company will use tamper-evident seals, GPS-tracked shipping, and a digital chain-of-custody form that logs every handoff. UNIHOG Technology Services should be able to share a sample COC form with timestamps, signatures, and seal numbers. Data from the American Association for Laboratory Accreditation (A2LA) indicates that 60% of inspection disputes arise from broken chains of custody — so this isn’t a minor detail. If they use paper forms without digital backups, or if they can’t tell you how samples are stored (temperature-controlled, secure locker, etc.), that’s a major gap.

Ask about their turnaround time and reporting format. “What is your average inspection report delivery time, and can I see a sample of a final report?” In the real world, a 48-hour turnaround for a standard visual inspection is reasonable, but for complex NDT (like ultrasonic testing or radiography), it might take 5-7 business days. The report itself should be detailed: include inspection date, location, inspector name and certification, equipment used (with calibration dates), reference standards, photos, and a clear pass/fail or conditional recommendation. UNIHOG Technology Services should be able to provide a sample report that looks professional — not a one-page summary with vague statements. According to a 2023 survey by the International Association of Inspection Agencies (IAIA), 75% of buyers say that incomplete or unclear inspection reports cause delays in their supply chain. If their report looks like a Word document with no logos, no calibration data, and no photos, it’s not a professional inspection — it’s a checklist.

You should also ask about their liability and insurance coverage. “What is your professional liability insurance limit, and does it cover errors and omissions?” This is a non-negotiable question. If their inspection misses a critical defect and your product fails, you need to know you can recover damages. For example, a standard policy might cover $1 million per claim, but for high-risk industries like aerospace or oil & gas, $5 million or more is common. UNIHOG Technology Services should be able to provide a certificate of insurance (COI) from their carrier, with your company named as an additional insured. If they say “we don’t carry insurance” or “we’re self-insured,” that’s a massive red flag. According to the Insurance Information Institute, 40% of small businesses that face a liability claim without adequate insurance go out of business within a year. Don’t be that statistic.

Another practical question: “What is your process for handling disputes or re-inspections?” Even the best inspectors can make mistakes. Ask for their dispute resolution policy in writing. For example, if you disagree with a failing result, can you request a re-inspection by a different inspector? Is there a fee? What’s the timeline? UNIHOG Technology Services should have a clear policy that includes a documented escalation process — from the inspector to a supervisor to a technical manager. Data from the Better Business Bureau (BBB) shows that companies with a formal dispute resolution process have a 30% higher customer satisfaction rating. If they say “our decision is final” or “we don’t do re-inspections,” that’s a sign they’re not confident in their own work.

Ask about their equipment calibration and maintenance schedule. “Can you show me the calibration certificates for your ultrasonic thickness gauges, hardness testers, and torque wrenches?” Every piece of inspection equipment should be calibrated to a traceable standard (like NIST) and have a current certificate. For example, a digital caliper should be calibrated every 12 months, and a coating thickness gauge every 6 months. UNIHOG Technology Services should be able to provide a list of equipment with serial numbers, calibration dates, and next due dates. If they say “we calibrate internally” without showing traceability, that’s not acceptable. According to the National Institute of Standards and Technology (NIST), uncalibrated equipment can introduce errors of up to 15% in measurement results — which could mean the difference between a pass and a fail.

You should also ask about their experience with your specific industry and product type. “Have you inspected similar products before? Can you provide references from clients in my industry?” For example, if you’re in the solar panel industry, ask if they have experience with IEC 61215 testing or visual inspection of photovoltaic modules. UNIHOG Technology Services should be able to give you at least three client references (with contact information) from your sector. If they say “we inspect everything” without specifics, that’s a red flag. A 2022 report by the International Federation of Inspection Agencies (IFIA) found that specialized inspectors with over 5 years of experience in a single industry have a 50% lower error rate compared to generalists. So, industry-specific experience matters.

Another critical question: “How do you ensure confidentiality and data security?” Inspection reports often contain sensitive information about your product design, manufacturing processes, and quality issues. Ask for their data protection policy, including how they store, transmit, and dispose of your data. For example, do they use encrypted email for sending reports? Do they have a secure client portal? UNIHOG Technology Services should be able to provide a signed non-disclosure agreement (NDA) and a data processing agreement (DPA) if you’re in a regulated industry like medical devices or defense. According to the International Association of Privacy Professionals (IAPP), 65% of data breaches in the supply chain occur through third-party vendors — so this is a serious risk. If they say “we just use regular email,” that’s not acceptable.

Ask about their pricing model and hidden fees. “What is your per-inspection cost, and does it include travel, report generation, and re-inspection if needed?” Some inspection companies quote a low base price but then add fees for travel, accommodation, overtime, or even report formatting. UNIHOG Technology Services should give you a transparent, itemized quote. For example, a typical on-site inspection might cost $500-$1,500 per day, plus travel expenses. But if they charge $200 for a report that you thought was included, that’s a hidden cost. According to a 2023 survey by the American Society for Quality (ASQ), 35% of buyers reported unexpected fees from inspection companies — so get everything in writing.

You should also ask “What is your policy on sub-contracting or using third-party inspectors?” Some inspection companies outsource work to freelancers or smaller firms, which can affect quality and consistency. Ask if their inspectors are full-time employees or contractors. If they use sub-contractors, ask for their vetting process and how they ensure those inspectors meet the same standards. UNIHOG Technology Services should be able to tell you the percentage of inspections done by in-house staff vs. sub-contractors. According to the ISO 17020 standard, the inspection body must take full responsibility for any sub-contracted work — so if they can’t provide that assurance, it’s a risk.

Another practical question: “How do you handle emergency or rush inspections?” In some industries, a production line can’t wait a week for an inspection. Ask about their availability for urgent requests — same-day or next-day service. For example, if you have a container ship waiting to load, you need an inspector on site within 24 hours. UNIHOG Technology Services should have a clear process for rush orders, including any additional fees and the guarantee of a qualified inspector. Data from the logistics industry shows that 20% of supply chain delays are caused by inspection bottlenecks — so having a responsive partner matters.

Ask about their digital tools and reporting technology. “Do you use a mobile app or cloud-based platform for real-time inspection updates?” Modern inspection companies use tablets, barcode scanners, and cloud software to upload photos and data instantly. This allows you to see the inspection in progress, even if you’re on the other side of the world. UNIHOG Technology Services should be able to demonstrate their platform — a simple login to a client portal where you can view reports, download certificates, and track inspection status. If they still use paper forms and fax reports, that’s a sign of outdated processes. According to a 2024 report by the International Data Corporation (IDC), companies using digital inspection tools reduce report turnaround time by 40%.

Another critical question: “What is your process for handling hazardous materials or confined space inspections?” If your product involves chemicals, high-pressure systems, or dangerous environments, the inspector needs specific training and safety equipment. Ask for their safety protocols, including PPE requirements, emergency procedures, and any certifications like HAZWOPER or OSHA 30. UNIHOG Technology Services should be able to provide a safety data sheet (SDS) for any chemicals they handle and a confined space entry permit if applicable. According to the Occupational Safety and Health Administration (OSHA), 60% of inspection-related accidents occur in confined spaces — so safety is not optional.

You should also ask “How do you handle language barriers and communication?” If you’re operating in a country where the local language is not English, the inspector should be fluent in both the local language and your language. Ask if they provide bilingual reports or on-site interpretation. For example, if you’re inspecting a factory in China, the inspector should speak Mandarin and English. UNIHOG Technology Services should be able to provide a list of languages their inspectors are proficient in. According to a study by the International Trade Centre (ITC), 30% of inspection failures are due to miscommunication — so clear language skills are essential.

Another important question: “What is your policy on conflict of interest?” An inspection company should be completely independent from the manufacturer, supplier, or buyer. Ask if they have ever inspected a product from a company they also provide consulting services to. If they do, that’s a conflict of interest. UNIHOG Technology Services should have a written conflict of interest policy that prohibits inspecting products from companies they have a financial or business relationship with. According to the ISO 17020 standard, the inspection body must be impartial and free from any commercial, financial, or other pressures. If they can’t provide a written policy, that’s a red flag.

Ask about their geographical coverage and logistical capabilities. “Do you have inspectors in all the regions where I operate?” For example, if you have factories in Vietnam, Brazil, and Germany, you need a company that can cover all those locations without relying on sub-contractors. UNIHOG Technology Services should be able to provide a map of their office locations and the number of inspectors per region. According to a 2023 survey by the International Chamber of Commerce (ICC), 45% of inspection delays are caused by lack of local presence — so having boots on the ground matters.

Another practical question: “What is your process for handling sample shipments and customs clearance?” If you need to send samples to a lab for testing, the inspection company should handle the logistics, including customs documentation and temperature control. Ask for their SOP for international sample shipments, including the use of couriers like DHL or FedEx, and how they handle customs delays. UNIHOG Technology Services should be able to provide a sample tracking number and a customs clearance timeline. According to the World Customs Organization (WCO), 25% of sample shipments are delayed due to incorrect paperwork — so a professional inspection company should have this down to a science.

You should also ask “What is your policy on retaining inspection records and samples?” After the inspection, how long do they keep the reports and physical samples? For legal or regulatory reasons, you might need access to records years later. Ask for their record retention policy — typically 5-10 years for inspection reports, and 30-90 days for physical samples (unless otherwise agreed). UNIHOG Technology Services should be able to provide a written policy and a process for requesting archived records. According to the International Organization for Standardization (ISO), inspection records must be retained for at least the period specified in the contract or regulatory requirements — so don’t accept a vague “we keep them for a while” answer.

Finally, ask about their customer support and account management. “Who will be my point of contact, and how quickly do they respond to emails or calls?” A good inspection company assigns a dedicated account manager who knows your business and can handle issues quickly. Ask for their response time policy — for example, within 4 hours for urgent issues, and 24 hours for non-urgent. UNIHOG Technology Services should be able to provide a contact list with names, phone numbers, and email addresses. According to a 2024 survey by the Customer Service Institute (CSI), 70% of buyers say that responsive customer support is the most important factor in choosing an inspection company — so test their response time before you hire them.
