Third-Party Inspection Services for China Imports
QIMA, SGS, Bureau Veritas, and Intertek compared. What each inspection type costs, what inspectors actually check, and when to skip the formal process.
Skipping inspection to save $300 is how you lose $15,000. I’ve seen it happen more than once. An importer trusts their supplier, skips the pre-shipment check, and gets a container of electronics with the wrong firmware, missing accessories, or a 40% defect rate.
Hire an inspector. Here’s how to do it right.
The Main Players and What Sets Them Apart
QIMA (formerly AsiaInspection) is the most popular choice for small and mid-size importers. They operate across China, Vietnam, Bangladesh, and most sourcing countries. Their online booking system is genuinely easy: you enter the factory address, product details, inspection date, and pay by credit card. Reports come back within 24 hours via an app, with photos and a pass/fail summary.
QIMA’s pricing starts around $229 per man-day in most Chinese provinces. Higher-cost regions like Shanghai and Guangzhou run closer to $299. They’re fast, well-documented, and their app-based reporting is cleaner than competitors.
Bureau Veritas and SGS are the giants. Both have been operating in China for decades. Their factory audits carry more weight with large retail buyers like Walmart or Target, who often require reports from approved inspection companies. For standard importers, they’re more expensive ($300-400/man-day) and slower to book than QIMA.
Intertek sits in the same tier as BV and SGS. Strong reputation for compliance testing, especially for FCC and UL certification pre-testing. If you’re heading into a formal certification process, Intertek can sometimes combine inspection with pre-compliance testing.
V-Trust is a smaller player focused almost exclusively on China, Vietnam, and India. Pricing is competitive with QIMA. Some importers prefer them for their inspector consistency in specific regions.
For most electronics importers, QIMA is the default choice. You get professional reports, reliable scheduling, and a booking process that doesn’t require a phone call to a sales rep.
Inspection Types Explained
Not all inspections are the same. Here’s what each type actually does.
Factory Audit happens before you place any order. The inspector visits the factory and evaluates their production capacity, quality management systems, equipment, workforce size, and compliance with labor and safety standards. You get a report showing whether the factory can actually produce what they claim.
Factory audits run $350-500 because they take a full day and require a more experienced inspector. Do this before your first large order with a new supplier.
Pre-Production Inspection (PPI) happens after the supplier receives your materials but before production starts. The inspector confirms the raw materials match your specs, the components are the right grade, and the factory understands your production requirements. Good for catching problems before they’re baked into 5,000 units.
During Production Inspection (DUPRO) happens when 20-30% of your order is complete. The inspector checks a sample of finished units against your specs and pulls early units to test. If defects appear at this stage, you still have time to ask the factory to rework before the full production run is done.
DUPRO is the inspection most importers skip and most should not skip. It’s your best chance to catch a systematic defect before it hits 100% of your order.
Pre-Shipment Inspection (PSI) happens when at least 80% of the order is finished and packaged. This is the most common inspection type. The inspector uses AQL sampling tables to pull units from your order, tests them against your spec sheet, checks packaging, quantities, and barcodes.
PSI is the minimum baseline for any order over $5,000.
Container Loading Supervision happens at the factory when your goods are loaded into the shipping container. The inspector counts cartons, checks seal numbers, and confirms the right product is in the container. For large orders or when you’ve had quantity discrepancies before, it’s worth the extra cost.
What AQL Levels Mean
Every PSI report uses AQL (Acceptable Quality Level) sampling. The AQL level determines how many units get inspected and how many defects are acceptable before the shipment fails.
AQL 2.5 is standard for general merchandise. AQL 1.0 is stricter, used for higher-value or safety-related products. Most electronics orders use AQL 2.5 for major defects.
Defects break into three categories:
Critical defects are safety hazards or legal compliance failures. A cable that shocks the user, a product that fails FCC requirements, or packaging with false claims. Zero tolerance. One critical defect fails the inspection.
Major defects are functional failures or significant quality problems. A wireless earbud where one side doesn’t work, an LED strip that flickers, a charger that outputs the wrong voltage. These fail at a low threshold.
Minor defects are cosmetic issues: small scratches, slight color variation, minor packaging dents. Some are acceptable within AQL limits.
When you read an inspection report, look at the defect breakdown first. A “FAIL” on minor defects with zero major or critical defects is very different from a “FAIL” on major defects.
How to Book an Inspection
QIMA’s process is straightforward. Create an account, click “Book Inspection,” enter the factory name and address, your product details, your PO number, the quantity to be inspected, and your inspection checklist.
The checklist is important. QIMA provides a default electronics checklist, but you should customize it. Add your specific product dimensions, approved colors, barcode numbers, packaging requirements, and any function tests you need. If your product needs to pair with a phone via Bluetooth, put that on the checklist. If it needs to charge at 65W, specify that.
48-hour notice to the factory is required. This is industry standard. You or your inspection company notifies the factory at least 48 hours before the inspector arrives. Some importers worry this lets factories hide problems. It does let factories prepare. But a factory that does systematic fraud doesn’t change in 48 hours, and a legitimate factory just uses the time to make sure your goods are ready to be counted.
Book inspections at least 1 week before your expected production completion date. Inspectors have limited availability in some regions, especially around Chinese New Year and Golden Week.
What Inspectors Check and What They Don’t
A good PSI inspector will check: unit count vs. purchase order, carton labeling and barcodes, outer carton condition, random unit selection using AQL tables, function tests per your checklist, visual inspection for cosmetic defects, safety mark verification (CE, FCC, UL if applicable), and packaging contents (accessories, manuals, cables).
What they won’t do: run multi-hour soak tests, conduct electrical safety tests with specialized equipment, test for electromagnetic interference, or certify compliance with any regulatory standard. Inspectors catch obvious defects and spec mismatches. They don’t replace lab testing.
For electronics with FCC or CE certification requirements, the compliance documents come from a test lab, not from an inspection company. Don’t confuse the two.
When Factories Refuse or Resist
A factory that refuses inspection is a serious red flag. Established electronics factories deal with third-party inspections constantly. It’s a normal part of doing business with international buyers.
If a factory says inspectors “aren’t allowed” or asks you to “trust them” instead, push back. If they still refuse, take that seriously.
More common than outright refusal: factories who want to know which specific units will be inspected. Don’t tell them. The inspector selects units randomly after arriving.
Bribery attempts happen. It’s less common with major inspection companies like QIMA and SGS, because their inspectors know it gets reported. Smaller local inspection outfits have more variable integrity. If you hear from a supplier that “the inspector was paid,” get a second inspection from a different company.
When a Sourcing Agent Makes More Sense
Formal inspection companies are great for one-time vendor qualification and for orders where you need a documented report. But if you’re ordering regularly from the same suppliers, a sourcing agent in China who does QC on your behalf often makes more sense.
A local sourcing agent with real factory relationships can visit during production, flag problems before they escalate, and negotiate rework directly with the factory. They can also do container loading supervision and factory visits more flexibly than a formal inspection booking allows.
The tradeoff: sourcing agents don’t produce standardized AQL reports. If you need documentation for a retail buyer or insurance claim, QIMA or SGS reports carry more weight.
Use formal inspection companies for the first 2-3 orders with any new supplier, and when you need documented evidence. Switch to a trusted sourcing agent for ongoing QC once the relationship is established.
FAQ
How much does a third-party inspection in China cost?
Pre-shipment inspections run $229-350 per man-day depending on the provider and region. QIMA starts at $229 in most provinces. SGS and Bureau Veritas charge $300-400. Factory audits cost more because they take longer, typically $350-500. The 48-hour notice and travel costs are usually included in the man-day rate.
What’s the difference between a PSI and a factory audit?
A Pre-Shipment Inspection checks finished goods against your spec sheet before they ship. A factory audit evaluates the supplier’s facility, capacity, and quality management systems before you place an order. Factory audits are broader and more expensive. Most importers do a factory audit once per supplier and PSIs on every order.
Can I hire QIMA or SGS directly, or do I need to go through a sourcing agent?
You can book directly through QIMA’s website with a credit card. No intermediary needed. SGS and Bureau Veritas require more setup but also have direct booking. Most importers book QIMA directly for standard inspections.
What happens if the inspection fails?
A failed inspection means the shipment doesn’t meet your quality standards. You have several options: ask the factory to rework the defective units and re-inspect, negotiate a price reduction to account for the defect rate, reject the shipment entirely, or accept it with a claim filed for compensation. Don’t release payment until you’ve decided how to handle a failure.
Do I need to be present at the inspection?
No. The inspector works independently and sends you a report. You can watch live via video call if you want, and some inspection companies offer this. But most importers just review the report when it arrives. If you have a complex product with specific function tests, provide detailed written instructions in advance rather than trying to supervise remotely.
