Answers to Questions on Vacuum Flask Proofing Fees (4): Demystifying Price Differences, Detailed Cost Breakdown and Refund Rules

Stories in the cup, warmth in life. Hello everyone, this is "Dong Dong's Cup Talk". As an original Guangdong factory deeply engaged in vacuum flask production for many years, we serve custom clients from all over China on a daily basis, including startup brands, trading merchants and large-scale purchasers. https://www.umbottle.com/ProductsDetail-VB-10439.htmlWe oversee the entire customization process from demand communication and detail verification to finalizing the proofing plan. Yet whenever we quote the proofing fee, we frequently hear customers ask: “Why are proofing fees higher at Guangdong factories, while Zhejiang manufacturers offer much lower quotes?”

At first, even after repeated explanations, we still struggled to resolve customers’ confusion, and some even terminated cooperation over this issue. To clarify the real reason behind the price difference between the two regions, we specially visited multiple vacuum flask factories of the same category in Zhejiang in person. After in-depth communication, we uncovered the core truth: the low proofing prices of Zhejiang factories are not universal pricing, https://www.umbottle.com/ProductsDetail-VB-10439.htmlbut differentiated quotations based on customer qualifications. In contrast, Guangdong factories adhere to fact-based cost accounting and equal treatment for all clients, with proofing fees fully corresponding to actual costs and no dual charging standards.

IV. Proofing Fees Are Fully Refundable! Clear Commitment and Implementation Standards

To fully ease customers’ concerns, https://www.umbottle.com/ProductsDetail-VB-10439.htmlwe have always implemented a policy of “full refund or deduction of proofing fees against bulk order payments”, with transparent rules and well-founded implementation:

After customers pay the proofing fee, we strictly produce samples in accordance with requirements and support revisions throughout the process until samples are confirmed as qualified by the customer.

If customers place a bulk order within the agreed period (usually 3–6 months) and the order volume meets the factory’s regular minimum order quantity, https://www.umbottle.com/ProductsDetail-VB-10439.htmlthe proofing fee can be fully refunded or directly deducted from the bulk order payment.

If sample revisions go beyond the initial requirements and incur additional costs, both parties shall negotiate the sharing of such incremental expenses, while the basic proofing fee will still be refunded as agreed.

In simple terms: as long as you have genuine cooperation intentions and place a bulk order on schedule, https://www.umbottle.com/ProductsDetail-VB-10439.htmlthe proofing fee acts as a sincerity deposit and will be fully returned in the end — equivalent to free proofing.
