Product quality only has real value when it reaches the buyer intact and exactly as promised. TTPLYWOOD has built a packaging, container loading, and batch traceability process to ensure that outcome — without exception.
Packaging is not just wrapping the goods — it is a protection system against moisture, impact, and deformation throughout sea transit that may last 3–6 weeks under constantly changing conditions.
Panels are stacked flat and packed into bundles according to the standard sheet count or buyer requirements. Packaging is carried out in a dry warehouse to avoid direct exposure to outdoor conditions.
Each bundle is clearly labeled with full technical and traceability information. Labels are applied on the PE wrap in a position that is easy to read during inspection at the port or at the buyer’s warehouse.
Mandatory data fields on every TTPLYWOOD export bundle label:
Incorrect container loading is one of the leading causes of plywood damage during sea transport: warping, edge cracking, moisture damage, and bundle shifting. TTPLYWOOD controls every step carefully.
Before loading begins, the container is inspected thoroughly: the floor must be free from rot or holes, the roof must show no leaks, and doors with seals must close completely. Internal moisture is checked using a measuring device. Containers showing damp marks, unusual odor, or signs of chemical contamination are rejected and replaced before loading.
Each shipment has a container loading plan prepared by the export team and approved in advance. Goods are loaded under the rule that heavier/thicker items go below and lighter/thinner items go above, with bundle weight distributed evenly. The gap between bundles and container walls is kept at a minimum of 5 cm to allow for bracing.
Voids between bundles and container walls are secured using airbags or wooden braces to prevent shifting when the vessel rolls. Silica gel desiccant bags are hung inside the container based on volume: minimum 1 kg per 10 m³. The desiccant quantity is recorded in the container loading file.
Before closing the doors and sealing the container, the shipping QC staff take a full photo record: inside view from the doors, quantity and condition of desiccant bags, bundle labels readable from the entrance, and the bracing arrangement. These photos are stored with the batch file and shared with the buyer upon request.
The container is sealed with a numbered seal (seal number recorded on the B/L). The seal number is verified against the delivery note, B/L, and photo records. After handover to the shipping line, the full document package (B/L, packing list, container photos) is compiled and sent to the buyer within 24 hours.
After the container is loaded onto the vessel, the export team sends ETD/ETA notification to the buyer and updates it if the sailing schedule changes. The shipment is tracked through the carrier’s tracking system, and the buyer is informed promptly in case of port delay or transshipment issues.
TTPLYWOOD’s batch traceability system ensures that if any quality issue arises — whether at the buyer’s warehouse or after installation — the related production batch, technical parameters, and inspection results can be identified immediately.
Each production batch is assigned a unique Batch Number from the start of manufacturing. This code follows the product through the full line and is printed on each bundle label, recorded in QC sheets, Vinacontrol reports, and the packing list.
Example: TTP-2506-0142 = TTPLYWOOD, June 2025, batch number 142. The batch code is unique and never duplicated in the system.
Each batch code is linked to: incoming material records, production logs (pressing parameters), internal QC sheets, Vinacontrol reports, packing lists, and B/L. Records are retained for at least 3 years.
When the buyer provides the batch code from the bundle label, TTPLYWOOD can supply all related records within 24 working hours. This supports factory audits, quality claims, and compliance verification.
For FSC orders, the batch code is also linked to FSC Chain of Custody records: input veneer/timber source, FSC supplier code, and the corresponding FSC certificate number.
When a buyer detects a quality issue after receiving the goods, TTPLYWOOD follows a clear and transparent response procedure — no avoidance, no shifting of responsibility.
The buyer sends photos, a description of the issue, and the batch code (from the bundle label). TTPLYWOOD acknowledges receipt within 4 working hours and provides a complaint tracking ticket number.
The corresponding batch file is reviewed: production parameters, QC results, and Vinacontrol report. If required, retained samples or a similar batch are re-tested in the laboratory.
The investigation conclusion and corrective solution (compensation, replacement, or discount) are communicated within 5 working days. Corrective action is implemented immediately in production to prevent recurrence.
Plywood is sensitive to moisture, impact, and storage conditions. Below are the most common risks in sea export shipments and the control measures used by TTPLYWOOD.
Risk: Condensation inside the container when the vessel passes through zones with major temperature differences can cause mold, warping, and surface blistering.
TTPLYWOOD prevention: Use double-layer PE for long-haul shipments, hang silica gel desiccant at 1 kg/10 m³, select containers with sound floors and roofs, and check container moisture before loading. Dry containers with ventilation are preferred.
Risk: Uneven stacking, runners placed too far apart, or unbalanced weight distribution can cause sagging and warping in the bottom sheets of the bundle.
TTPLYWOOD prevention: Follow the approved loading plan, keep runner spacing within 60 cm, place bundles fully horizontal, never lean them against the container wall, and perform a visual check before closing the doors.
Risk: Panel edges and corners are highly vulnerable to breakage and fiber tear-out if bundles strike the container wall or are mishandled by loading equipment at the port.
TTPLYWOOD prevention: Use corner protectors at the 4 corners of each bundle, place airbags between the bundle and container wall, mark labels with "HANDLE WITH CARE" and "DO NOT DROP", and provide written unloading instructions to the forwarder.
Risk: When a container carries cargo for multiple buyers or several similar product types, the risk of batch mix-up or wrong product delivery increases — especially during unloading at destination.
TTPLYWOOD prevention: Each bundle is labeled clearly with PO No., buyer name, and batch code. Cargo for different buyers is separated clearly in the container with visible division marks. The packing list is checked against actual sheet count before sealing.
TTPLYWOOD can provide container inspection photos, loading procedures, and sample packaging records for your review before placing an order.
