When sourcing SKD (Semi-Knocked Down) materials, the most critical factor is the degree of disassembly. You must verify if the kit includes pre-assembled sub-components (like engines or motherboards) or if it requires further specialized labor. Ensure the Dimensional Accuracy of parts meets international tolerances to avoid assembly line bottlenecks. Additionally, confirm that the Material Grade (e.g., steel hardness or plastic heat resistance) aligns with your final product's performance specifications.
