FAQ

The usual flow is: describe the application and requirement, we recommend matching grades, samples ship, you run a bench trial. Samples are typically 100-500 g, enough for several small-scale trials. To avoid a round of guesswork, tell us the product category (pressed powder, liquid foundation, lipstick, sunscreen), whether the system is water-in-oil or oil-in-water, the main sensory and performance targets, and the process conditions such as pressing pressure and dispersion equipment. With that, we can shortlist grades instead of having you test everything. Custom-treated samples take longer because the surface treatment is scheduled as a separate batch. Lead time is confirmed once the treatment plan is agreed.

For standard grades the MOQ follows the packaging format, typically one 25 kg drum, with some higher-value grades available in 5 kg or 10 kg packs. Custom-treated powders carry a higher MOQ because surface treatment is a batch operation and equipment cleaning costs cannot be spread over a small quantity. The exact figure depends on the treatment chemistry and process complexity. At the sampling stage, validate with standard grades first and discuss customisation once the direction is confirmed. This avoids committing to customisation costs while the direction is still uncertain.

Yes, customisation is one of our core capabilities. Adjustable variables include the treatment chemistry and coating level, the particle size distribution, and the blend ratio with other powders. The right starting point is your formulation problem, not a powder specification. A single symptom such as pilling in liquid foundation can map to three different treatment directions, so we first establish whether it is a dispersion, compatibility or over-absorption issue, and may ask for a sample to verify. Once a custom grade is confirmed, we retain a reference sample and build a technical parameter file, and subsequent batches run against that standard to hold batch-to-batch consistency.

Standard grades are normally stocked, with shipment scheduled after order confirmation. Custom grades are queued against the treatment process and take noticeably longer. Three factors drive lead time: whether the grade is standard, the packaging format, and whether additional test reports are required. If a project is time-critical, state the required arrival date at the enquiry stage so we can confirm against the production schedule rather than estimate. For export orders, remember that inspection, customs clearance and freight usually take longer than production itself, so build in that margin early.

Yes, all three. The COA is issued per batch with measured values for that batch; the MSDS follows the standard format; the TDS gives typical properties and application guidance. Do not confuse them. The COA covers actual data for the delivered batch and is used for acceptance. The TDS carries typical values and is used for formula design. The MSDS carries safety information for storage, transport and regulatory filing. For export or registration purposes we can also supply composition declarations, regulatory compliance statements and third-party test reports. Request these at the order stage so nothing is missing at customs.

Powder pricing has four components: raw material cost, processing method, particle size and purity control, and surface treatment. For the same nominal specification, most of the spread sits in the last two. A narrow particle size distribution means lower yield and higher cost, but noticeably better batch consistency and performance. Coating level and uniformity directly affect dispersion, and under-treatment cannot be compensated by dosing more. Neither gap shows up on a TDS; only testing reveals it. When comparing quotes, compare three things alongside price: the full particle size distribution curve (not just D50), the treatment chemistry and coating level, and historical batch-to-batch variation data. Buying on unit price alone often delivers a product that meets the spec sheet and still will not run.
