Which Industries Need Product Inspection?
Tetra Inspection provides specialised quality control services across a wide range of manufacturing sectors.
Textile & Garment
The textile and garment industry faces unique quality challenges — from fabric defects and colour inconsistencies to sizing errors and stitching flaws. Our inspectors verify fibre composition, colourfastness, tensile strength, and overall workmanship against international standards such as ISO 3758 and ASTM D5489. Whether you import fast-fashion basics or premium apparel, our textile inspection services help you avoid costly returns and protect your brand reputation.
Consumer Electronics
Electronic products demand rigorous functional testing and safety verification before shipment. Our electronics inspections cover visual checks, Hi-Pot testing, power consumption measurement, connectivity validation, and compliance with CE, FCC, and RoHS directives. We catch issues like dead pixels, battery defects, and firmware glitches that factory QC teams often miss — giving you confidence that every unit works as intended from the moment your customer opens the box.
Children & Baby Toys
Toys are among the most heavily regulated consumer products in the world. A single safety failure can result in recalls, lawsuits, and lasting reputational damage. Our toy inspections cover sharp edges, small parts choking hazards, lead and phthalate content, flammability, and mechanical durability. We verify compliance with EN 71, ASTM F963, CPSIA, and GB 6675 standards so your products reach children safely and meet the strictest regulatory requirements in any market.
Furniture
Furniture inspection requires evaluating structural integrity, surface finish, hardware functionality, and packaging adequacy for long-distance shipping. Our inspectors check for stability, load-bearing capacity, material quality, and assembly accuracy. We also verify that finishes are free from VOCs and that timber sourcing complies with environmental regulations. From flat-pack furniture to upholstered pieces, our inspections reduce damage claims and ensure your products arrive in showroom condition.
Home Appliances
Home appliances combine electrical, mechanical, and aesthetic requirements that all need to meet spec. Our appliance inspections include functional performance tests, electrical safety checks (ground continuity, insulation resistance, leakage current), cosmetic evaluation, and packaging verification. We test everything from small kitchen gadgets to large white goods, ensuring compliance with IEC, UL, and regional safety standards before your products ship to distributors and retailers.
Popular Inspection Destinations
Our full-time inspectors are based in major manufacturing hubs worldwide, ready to conduct quality control inspections within 24 hours of booking.
