## Services

### Pre-Shipment Inspection (PSI)
Final quality check conducted when production is 80–100% complete. Inspectors verify product quality, labeling, packaging, and quantity using AQL-based statistical sampling per ISO 2859-1. The most common inspection type for importers.

### During Production Inspection (DPI)
Quality check performed when 20–60% of production is complete. Catches defects early in the manufacturing process before the full run is finished.

### Initial Production Check (IPC / Pre-Production)
Conducted before or at the start of mass production. Verifies raw materials, components, and production setup meet specifications.

### Container Loading Check (CLC)
On-site supervision during container loading to verify correct quantities, proper handling, and loading sequence. Prevents shipping damage and short shipments.

### Supplier Verification
Independent verification of supplier legitimacy, capabilities, and reliability before placing orders. Includes business license checks, facility visits, and capacity assessment.

### Production Monitoring
Recurring on-site oversight across the entire production run instead of a single snapshot. An inspector makes scheduled, repeated visits to track workmanship, defect trends, and output pace using AQL sampling per ISO 2859-1, with daily or periodic reports so problems are escalated and fixed while corrections are still inexpensive. Suited to large, high-value, or deadline-critical orders and new suppliers.

### AI Quality Inspection
AI-assisted, human-in-the-loop inspection. Computer-vision models help trained inspectors flag visual defects, classify findings, and structure photo-backed report data faster and more consistently, while a qualified inspector verifies every flag and makes the final accept-or-reject decision. AQL sampling per ISO 2859-1 still governs the sample; AI augments inspectors rather than replacing on-site presence or human judgment.

### Remote Inspection
Live video-based quality check for situations where an on-site visit is not possible or not justified — factory lockdowns, tight deadlines, lower-value orders, or quick progress checks between physical inspections. A Tetra inspector directs factory staff through the inspection checklist over a live connection, capturing photos and recorded video, and delivers a documented report (typically same-day). Best used as a complement to on-site inspection, which remains the standard for statistically valid AQL sampling and hands-on testing.

### Toy Safety Testing
Coordinated and witnessed toy safety testing to EN 71 (Europe), ASTM F963, and CPSIA (United States). Tetra arranges testing through accredited, CPSC-accepted or EU-notified third-party laboratories, witnesses mechanical and physical checks on-site, and verifies test reports and certificates against your products and market. Tetra is not itself an accredited testing laboratory and does not issue test certificates — keeping its verification independent of the lab that performs the analysis.

## Industries Served

Consumer electronics, textiles and apparel, toys and children's products, furniture, automotive parts, food packaging, cosmetics, promotional products, home goods, and industrial equipment.

### Cosmetics & Personal Care Inspection
Quality and labeling inspection for makeup, skincare, haircare, fragrances, and toiletries. Inspectors verify fill levels and net content, closure and seal/leak integrity, color and texture against the approved sample, packaging and print quality, and label compliance (INCI ingredient lists, batch codes, period-after-opening symbols) against FDA and EU Cosmetics Regulation (EC) No 1223/2009 requirements. Where chemical or microbiological analysis is needed, Tetra coordinates and witnesses testing through accredited third-party labs — it is not a testing laboratory itself.

### Automotive Parts Inspection
Dimensional, material, and functional verification for OEM and aftermarket automotive components. Inspectors measure critical dimensions and tolerances against engineering drawings, confirm material grade and surface treatment, check fit with mating components, perform function tests, and verify part markings and transit-grade packaging. Criteria reference IATF 16949, SAE, and ASTM standards; Tetra is an inspection body and does not issue IATF certification. Specialized destructive or material analysis is coordinated and witnessed through accredited third-party labs.

### Promotional Products Inspection
Branding-accuracy and quality inspection for branded merchandise and giveaways. Inspectors verify logo placement, size, and orientation against artwork, match printed and embroidered colors to specified Pantone references, check print durability, and inspect the base product's material, construction, function, and packaging for multi-location distribution. Consumer-safety requirements (CPSIA, California Proposition 65, REACH) are verified through testing coordinated and witnessed with accredited third-party labs.
