ISO Systems, ISPM-15, PEFC and Full Traceability
Our quality framework combines ISO-based procedures with ISPM-15 heat treatment (56 °C for 30 minutes), PEFC chain-of-custody and end-to-end traceability. Each batch is documented for audits and export checks, reducing shipment delays. We pair process control with training, safety and environmental programs to keep your operations compliant and on schedule.

ISO 9001:2015 Certified | Traceable | Consistent | Customer-Focused
Our ISO 9001:2015 system governs every step—from incoming timber to finished goods—so your pallets, crates and packing solutions are built to the same specification every time. We maintain controlled documents, calibrated equipment, first-article checks and corrective/preventive actions, with full batch records available for audits and vendors.

Traceability & Documentation
Each production lot is traceable to materials, processes and inspections. Your team receives a concise QA pack: batch IDs, spec conformance checklist, non-conformance resolution (if any) and shipping verification. On request, we map our checkpoints to your internal SOPs to simplify goods-in QA.
Meeting Global Standards for Seamless Trade
For export-bound shipments, pallets and crates are routed through ISPM-15 heat treatment with segregated flows and batch-level certificates. We log probe temperatures/time, label compliant lots, and attach digital certificates for customs. Domestic cycles bypass treatment unless you specify otherwise.
- Treatment spec: Heat treat to 56 °C for 30 min (wood core); probe-logged and saved against your batch ID.
- Marking: IPPC/ISPM-15 stamp on two sides (Country–Facility–HT = Heat Treated). Repaired pallets are re-treated and re-marked.
- Segregation: Export-ready lots held in clearly marked areas to avoid mixing with domestic pallets.
- Documentation: Treatment Certificate (PDF) + traceability sheet (SKUs, quantities, work performed). Probe summaries available on request.
- At goods-in/customs: Match batch ID ↔ certificate, verify stamps, proceed.
- Special cases we handle: Composite panels (exempt under ISPM-15), moisture dry-down, customer policies (HT-only).



Circular & Green Initiatives
We treat sustainability as operational discipline: design for reuse, verify sources, and measure what matters so customers get reliable, compliant packaging with a lower footprint.
Since 2021, Yat Guan been offering PEFC-certified timber options for new builds and replacements and maintain chain-of-custody separation where specified. In parallel, our Pallet Repair & Reconditioning program extends the service life of your pallets through structured inspection, grading, repair, and optional ISPM-15 for export. Complementing both, we continue to tighten our efficiency and reduce our carbon footprint throughout our production and logistical pipelines.
Chain-of-Custody You Can Trust
Choose PEFC-certified timber to align with ESG and tender requirements. We maintain PEFC Chain of Custody across our operations. Certificate numbers for Yat Guan Pte Ltd in Singapore and Yat Guan Sdn Bhd in Malaysia are available in the digital certificates linked below.

PEFC-certified timber is controlled through physical segregation or quantity-based stock control, helping protect claim integrity throughout production and supporting responsible timber sourcing for customers with sustainability and compliance requirements. Where required, delivery notes and invoices can include the relevant PEFC claim and certificate reference for a clear audit trail.
For procurement, operations, and compliance teams sourcing wooden pallets, timber packaging, or export-ready packing materials, we can provide a clear summary of species and origin where available, product specifications, quantities, and PEFC status. Mixed orders containing both certified and non-certified timber products can be supplied within the same purchase order, with each line clearly identified for accurate booking, reporting, and internal control.
We follow PEFC trademark rules for all logo and label usage, and we verify any product or packaging artwork before issue. Where more complex situations arise, including mixed-species wooden pallets, recycled timber content, approved substitutions, or urgent material swaps, these are documented clearly so your sustainability records, sourcing documentation, and audit requirements remain accurate and up to date.

Our Commitment to You
We make it simple for audits by including claim and certificate details in the delivery paperwork for orders that use, or contain PEFC chain-of-custody timber.
Extend Lifespan, Reduce Waste, Protect Uptime
Our pallet repair and reconditioning program keeps wooden pallets in circulation longer, lowering total cost of ownership and landfill waste while maintaining safe, reliable handling. Each pallet is inspected, graded, repaired, and—where export is required—optionally ISPM-15 heat-treated. Units are marked and cycle-tracked for traceability and QA audits, with batch summaries available for your records.

- Service scope: structural repairs, board/block replacement, nail reset, deck alignment, optional ISPM-15 retreatment for export lots.
- Quality assurance: standardised inspection grades, usability warranty on repaired units, batch-level reports and certificates where applicable.
- Operational benefits: fewer urgent purchases, lower breakage and downtime, stable dispatch schedules, consistent load performance across your network.
- Measured outcomes: longer pallet lifecycle (tracked repair cycles), CO₂ and waste reduction per batch, and cost savings versus buying new.
- Compliance options: where new materials are needed, PEFC-certified timber can be specified on request to support responsible sourcing.

Need a closed-loop option right now?
See how we inspect, grade, repair, and track units end-to-end on our Pallet Repair Service page. Includes turnaround windows, usability warranty, ISPM-15 (on request), and batch-level traceability.
Leaner operations, lower emissions, measurable savings
We design for throughput and impact. Route-optimised deliveries, energy-efficient heat treatment, and material recovery keep your schedule tight while lowering waste and emissions—without adding steps for your team.

Route Optimisation
Consolidated runs and smart backhauls reduce empty miles and curb fuel burn while protecting delivery windows

Energy-Efficient HT
Calibrated cycles and load planning cut chamber time per pallet—meeting ISPM-15 specs with less energy.

Material Recovery
Non-conforming pallets are dismantled for component reuse; unusable timber goes to recycling streams instead of landfill.

Sustainability Ledger
Monthly roll-ups of pallets recovered, waste diverted and estimated CO₂e saved—ready for ESG reporting.
