Road Marking Paint Pre-Shipment Inspection Checklist for International Buyers
Pre-shipment inspection helps international buyers confirm that road marking materials match the approved order before they leave the factory.
A complete inspection should cover product identity, technical requirements, colour, quantity, packaging, labels, documents and container loading.
Finding a difference before shipment is normally easier and less expensive than resolving it after the goods arrive at the destination.
The inspection scope should be agreed before production so that the supplier can prepare the required samples, documents and access.
1 — Confirm the Purchase Order
The inspection should begin by reviewing the final purchase order or proforma invoice.
The product name, material type, colour, quantity, packaging, unit price and delivery term should match the approved commercial offer.
Thermoplastic, acrylic, MMA and glass bead products should be listed separately.
For multi-colour orders, the quantity of each colour should be checked independently.
Any change made after order confirmation should be recorded in an updated document.
2 — Verify the Product Type
Road marking materials with similar names may use different formulations and application methods.
The inspector should confirm whether the product is thermoplastic powder, one-component acrylic paint, two-component MMA material or road marking glass beads.
For MMA systems, Components A and B must be identified clearly.
The mixing ratio on the labels and documents should correspond to the actual product.
A single-component product should not be shipped when the buyer ordered a plural-component system.
3 — Check Product Specifications
The final product specification should be compared with the buyer’s technical requirements.
Relevant parameters may include density, colour, drying or curing time, softening point, glass bead content, application thickness and other agreed properties.
Not every parameter can be tested during a simple visual inspection.
The parties should therefore define which results will be supported by a supplier COA and which require laboratory or third-party testing.
The tested product and batch should be traceable to the shipment.
4 — Check Batch Numbers
Each package should carry a readable batch number or another traceability code.
Batch information allows the supplier to connect the shipment with production and quality records.
If several batches are included, their quantities should be recorded separately.
The batch numbers on the packages, COA and inspection records should remain consistent.
Packages without readable batch identification should be corrected before loading.
5 — Confirm Production and Shelf-Life Information
The manufacturing date and stated shelf life should be checked where applicable.
Buyers may require a minimum remaining shelf life upon arrival or delivery.
The shipping route and expected transit time should be considered.
Older stock should not be substituted without the buyer’s approval when a new production batch was agreed.
Storage instructions should also be visible on the package or supporting documentation.
6 — Verify the Colours
White, yellow, red, black and other colours should be compared with the approved order.
When a specific standard is required, the reference may be a RAL number, project specification or approved physical sample.
Digital photographs alone are not sufficient for precise colour approval.
The inspector should also confirm that packages with different colours are identified clearly.
Colour names and codes should remain consistent across labels, packing lists and technical documents.
7 — Inspect Product Appearance
Thermoplastic powder should be checked for moisture, contamination, hard lumps or abnormal colour.
Glass beads should remain clean, dry and free-flowing.
Liquid acrylic paint should show no visible leakage, severe separation or container damage.
MMA Components A and B should remain sealed and correctly identified.
Appearance checks do not replace laboratory testing, but they can identify obvious storage or packaging problems.
8 — Verify Net Weight
The stated net weight should be confirmed using an agreed sampling method.
A common export package may contain 25 kg of product, but the buyer should distinguish net weight from gross weight.
For MMA products, it should be clear whether the stated weight applies to each component drum or to a complete set.
The number of packages multiplied by the net weight should match the total ordered quantity.
Any permitted weight tolerance should be agreed before inspection.
9 — Inspect Bags
Thermoplastic paint and glass beads are commonly packed in bags.
The inspector should check seams, closures, inner liners and external surfaces for damage.
Bags should not show powder leakage, moisture stains or serious deformation.
The labels should remain firmly attached and readable.
If palletised, the bags should be stacked securely without crushing the lower layers.
10 — Inspect Drums and Pails
Liquid acrylic and MMA materials require sealed containers suitable for transportation.
The inspector should check lids, seals, handles and drum bodies.
Leaking, dented or damaged containers should be replaced before loading.
Components A and B should not be mixed on pallets without clear identification.
The packaging should remain stable during normal lifting, stacking and container movement.
11 — Review Package Labels
Labels should show the agreed product name, colour, component, net weight, batch number and production information.
For two-component material, the mixing ratio and A/B identification are particularly important.
Custom brand labels should match the final approved artwork.
Required language, importer information or destination markings should be checked.
Incorrect labels should be replaced rather than covered with temporary handwritten information unless the buyer approves.
12 — Check Product Quantities
The number of bags, drums and pallets should be counted by product and colour.
A total package count alone may hide a shortage in one colour and an excess in another.
For a 1:1 MMA system, the quantities of Components A and B must remain balanced.
Glass beads, primer, thinner and other accessories should be counted separately.
The final packing list should reflect the verified quantities.
13 — Review the Technical Data Sheet
The final TDS should correspond to the product being shipped.
It should provide relevant information about application, thickness, consumption, drying or curing, storage and packaging.
For MMA products, the component ratio and working conditions must match the supplied system.
Draft or general data sheets should be replaced with final versions when the buyer requires approved documentation.
The product name on the TDS should be consistent with the package labels.
14 — Review the Safety Data Sheets
Safety data sheets should be available for materials that require them.
A two-component MMA system may require separate SDS documents for Components A and B.
Primer, thinner or related chemicals should also have their own documentation when included.
The SDS information should correspond to the actual product and transport arrangement.
These documents may be needed by the carrier, customs agent, warehouse and construction team.
15 — Review the Certificate of Analysis
The COA should identify the product, batch and relevant quality results.
It should not be a generic certificate without a connection to the delivered material.
The buyer should compare the reported parameters with the agreed specification.
If third-party testing is required, the report number and sample identity should also be checked.
Any untested or pending parameter should be identified before shipment.
16 — Review Export Documents
The commercial invoice, packing list and other export documents should use consistent product descriptions and quantities.
The buyer and supplier details, trade term, ports and destination should be correct.
If a certificate of origin or inspection certificate is required, its processing status should be confirmed.
For letter-of-credit transactions, document wording must comply with the credit conditions.
Draft documents should be reviewed before final issuance.
17 — Inspect Pallets
Pallet type and quantity should match the order.
Wooden pallets may require treatment or certification depending on destination regulations.
Pallets should be dry, stable and suitable for the product weight.
Stretch wrapping or securing materials should hold the packages without damaging them.
Mixed products on one pallet should be identified clearly.
18 — Inspect the Container
The empty container should be inspected before loading.
It should be clean, dry and free from strong odours, holes or visible water entry.
The floor should be suitable for the package weight and loading method.
Container moisture can damage thermoplastic powder, glass beads and paper labels.
The container number and condition should be recorded before the goods enter.
19 — Monitor Container Loading
Packages should be loaded according to a safe and practical arrangement.
Weight should be distributed evenly, and drums should be protected from shifting during transportation.
Products and colours should be positioned in a way that allows verification.
The final package count should be checked during loading.
Photographs should show the container condition, loading process and completed arrangement before the doors are closed.
20 — Record the Seal Number
After loading, the container should be closed and sealed.
The seal number should be photographed and recorded on the inspection or shipping documents.
The container number and seal number must correspond to the shipment.
Any seal change before departure should be documented.
This step supports cargo traceability during transportation.
21 — Prepare an Inspection Report
The report should summarise the order, inspected quantity, sampling method and findings.
Photographs of packages, labels, colours, batches, pallets, loading and seals should be included.
Any deviation should be listed clearly with the corrective action taken.
The report should distinguish between visual checks, document reviews and laboratory results.
Buyer approval should be obtained where required before shipment release.
22 — Use Third-Party Inspection When Necessary
A buyer may appoint an independent inspection company for large, technical or high-value orders.
The inspection scope, sampling method and acceptance criteria should be agreed before production.
Third-party inspection can verify quantity and visible conditions, but it does not automatically confirm every technical property.
Laboratory testing may still be required for specific performance parameters.
The inspection cost and schedule should be included in the commercial agreement.
Conclusion
A road marking material pre-shipment inspection should cover the product, packaging, documents and container loading.
Buyers should verify product type, colour, batch number, net weight, package quantity and component balance.
The TDS, SDS, COA, invoice and packing list should correspond to the actual goods.
Bags and drums must remain sealed, correctly labelled and suitable for export transportation.
Photographs, inspection records and container seal information provide useful shipment traceability.
A clear inspection plan helps buyers identify differences before departure and reduces quality, customs and delivery risks after arrival.
