If you find yourself needing to make a change to an order after production has started at the factory, the short answer is: it depends, but it is often possible with clear communication and an understanding of the implications. The feasibility hinges entirely on the production stage, the nature of the change, and the factory's specific workflow and policies.

In the early stages of production, such as during material cutting or initial assembly, minor modifications might be accommodated. For instance, adjusting a color shade, modifying a small design detail, or slightly altering quantities may be negotiated. However, this typically requires immediate action. You must contact your supplier or agent without delay, as every hour counts once the production line is active.

More significant changes, like altering core materials, major design elements, or product dimensions, become exponentially more difficult and costly as production progresses. If the change requires scrapping already-processed materials or components, you will likely be responsible for those costs and for the new materials. It will also almost certainly delay your original shipping schedule.

The key is proactive and precise communication. Provide the factory with extremely clear, updated specifications, diagrams, or samples. Be prepared to discuss and likely approve any additional charges (Change Orders) and revised timelines in writing. A good factory partner will work with you to find a solution, but they will also be transparent about the disruptions and costs involved.

Ultimately, while post-production-start changes are a reality in manufacturing, they are best avoided through meticulous planning and confirmation of all details before the production order is finalized. If changes are unavoidable, addressing them with speed, clarity, and a cooperative mindset is crucial to finding a workable resolution.
