FAQ
Q: In addition to your internal Certificate of Analysis, can you arrange for independent third-party testing?
A: Yes. We support third-party testing by a designated laboratory prior to shipment. All testing parameters must be confirmed in advance to avoid additional costs or schedule delays.
Q: How do you handle color variations between different production batches?
A: We strictly monitor color specifications for every batch. Under normal storage conditions, there is no visible color difference. We will proactively notify the buyer if there are any slight fluctuations in specifications.
Q: If I switch from my current supplier to your PVP K25, is re-validation required?
A: Minor adjustments may be necessary. We can provide reference technical data to help shorten your qualification process, though the final validation must be completed by your company.
Q: What measures do you take to prevent cross-contamination during production?
A: Our PVP products are manufactured on dedicated production lines, and we maintain records of line cleaning. Line changeover validation is completed prior to the production of high-purity grade products.
