We need to push the delivery.

“交期需要提前” is the request every factory manager dreads — not because they don’t want to help, but because production scheduling is a carefully balanced system and your acceleration request is asking them to unbalance it. Chinese factories plan production slots days or weeks in advance. Raw materials are ordered to arrive in sync with the production start date. Labor is allocated. Machine time is booked. Moving your delivery forward means reshuffling all of these, which creates costs and risks that someone has to bear.

The most credible way to ask for acceleration is to acknowledge the cost. 我们愿意付加急费 (we’re willing to pay a rush fee) transforms the request from “do me a favor” to “let’s renegotiate the terms to reflect the new timeline.” A rush fee (加急费, jiā jí fèi) of 10-30% of the order value is standard for genuine schedule compression. It covers overtime labor, reprioritizing other orders, and possibly expedited material procurement. If the factory quotes a rush fee, they’re taking your request seriously. If they waive it, they either have genuine slack in their schedule or they’re not actually planning to accelerate.

If the factory can’t move the delivery date, the right response is to accept it: 理解, 那按原来交期走 (understood — go with the original schedule). Pushing harder when the factory has said no wastes relationship capital and may result in a compromised product as they cut corners to hit an unrealistic date. A better follow-up than insisting is: 那能不能先把一部分发出来? 剩下的按原交期 (can you ship part of it first? The rest on the original schedule). A partial shipment (分批出货, fēn pī chū huò) often satisfies the urgent need without requiring the factory to compress the entire production. This is a practical compromise that experienced buyers use regularly.
