Quality Control & International Compliance
From raw material testing to container-loading sign-off, DHT operates systematic quality controls and site-specific audit documentation to meet the commercial standards of leading global retailers.
Our 6-Step Quality Control Workflow
Systematic quality gates embedded across every stage of manufacturing
Incoming Material & Component Checks
Moisture testing (8-12% kiln-dried timber), aluminium wall thickness, fabric density and foam resilience validation before production release.
In-Line Production Inspections
Verification of joinery tolerances, mortise and tenon joints, robotic and manual weld penetration, and structural rigidity across active assembly lines.
Pre-Packing & Surface Finishing Checks
Inspection of powder-coating adhesion, wood protective finishes, stainless steel hardware and trial set assembly before boxing.
Final Random Inspection to Agreed AQL
Statistically rigorous sampling to international AQL standards (Major 1.5-2.5, Minor 4.0, Critical 0) before release for container packing.
Packaging, Labelling & Container Loading
ISTA drop-test verification, barcode validation, carton burst strength and strategic dunnage placement during container stuffing.
Corrective Action & Traceability Follow-up
Complete batch documentation and continuous manufacturing process improvements for every production programme.
Testing & Compliance for Your Market

Sustainability & Resource Efficiency
Traceable materials, high cutting yields, and circular biomass energy management
100% Timber Traceability
Every log and plank is tracked from certified FSC forest concessions through kiln-drying to final packaging, guaranteeing legal timber origin and zero deforestation.
Cutting Yield & Biomass Recovery
Computer-aided timber cutting achieves up to 82% recovery. 100% of solid wood offcuts and clean sawdust are converted into finger-joint furniture components or boiler biomass fuel.
Clean Finishing & Recyclable Packaging
Powder coating booths feature cyclone powder reclamation to minimize waste. All export cartons use recyclable corrugated cardboard and dunnage complying with international eco-directives.
Site-Specific Audits & Chain of Custody
Certifications including FSC CoC, ISO 9001, ISO 14001, BSCI, and SMETA are site-specific. Documented audit reports and valid scopes for the nominated production facility are provided directly to qualified buyers during programme onboarding.
