When OS-9012 arrives damaged, do not immediately purchase a second shipment. First, verify the product and transport details, inspect the material on delivery, record all visible issues, and contact the supplier for an assessment. Keeping the packaging, delivery records, quality documents, and shipment evidence will help coordinate a technical review and any claim. The product’s storage requirements and stated 12-month shelf life should also be considered.
OS-9012 is intended primarily as a curing agent for waterborne two-component polyurethane systems. It may also be used as an additive in hydroxyl-free resin systems. Its listed performance characteristics include high crosslinking density, resistance to water and chemicals, very low VOC emissions, low viscosity, and convenient manual mixing.
Transit investigations should distinguish shipping damage from problems caused by storage or later dilution. OS-9012 generally shows good compatibility with esters, ether esters, xylene, naphtha, and other solvents. However, dilution should be performed with a urethane-grade solvent containing less than 0.05% water. Using unsuitable or wet solvent may reduce storage stability and complicate the assessment of whether the material was damaged during transportation.
Document the product name, batch information, package condition, delivery date, visible leakage or deformation, and any quality observations. Keep the original shipment and related evidence available for review. Factory quality control, technical support, formulation references, and the stated 12-month shelf life can help determine whether the material remains usable or whether a commercial remedy is needed.
There is no single transport method specified as universally best for OS-9012. Sea freight, air freight, express courier, and rail freight may all be considered according to the customer’s requirements. Before dispatch, agree on the selected method, expected delivery condition, inspection procedure, and process for handling damage in transit.

| Transport planning | Sea, air, express courier, and rail freight are available | Allows the buyer to match transportation with delivery and handling needs |
| Quality assessment | Factory inspection may cover solid content, pH, viscosity, particle-size distribution, and related indicators | Provides evidence for evaluating the received material before replacement |
| Technical assistance | Technical support, reference formulas, and a stated 12-month shelf life | Helps determine usability, storage effects, and application suitability |
| Order terms | R&D, manufacturing, and direct sales; 900 KG MOQ; stated delivery period of 7-10 days | Enables confirmation of replacement quantities, timing, and commercial conditions |
| Payment control | 100% advance TT, or 30% deposit with 70% due before shipment | Highlights the need to settle the damaged-shipment review before issuing another payment |
What is the first step if OS-9012 is damaged on arrival?
Photograph and record the package and product condition, retain delivery evidence, and contact the supplier before ordering replacement material. Technical support and quality information can help establish the appropriate resolution.
Which delivery methods can be used for OS-9012?
Sea freight, air freight, express courier, and rail freight are available. The final choice should reflect the customer’s schedule, handling requirements, and agreed process for transit damage.
Can any solvent be used to dilute the product after delivery?
No. OS-9012 is generally compatible with esters, ether esters, xylene, naphtha, and other solvents, but dilution should use a urethane-grade solvent with water content below 0.05%. Incorrect dilution can affect storage stability.
Preventing a second payment starts with inspection and documentation, not immediate replacement. Confirm the identity and condition of OS-9012, preserve delivery evidence, and request a technical assessment before authorizing a new TT payment. Buyers should also verify the shipping method, quality data, shelf-life status, replacement terms, 900 KG MOQ, and stated 7-10-day delivery period.
