FAQ

Questions before you order

Practical answers for wholesale buyers and private-label partners.

Can you supply products under our own brand?

Yes. OEM and private-label supply are available. Send us your product, brand, label-language and packaging requirements so we can confirm a suitable solution.

What is the minimum order quantity?

The minimum quantity depends on the product and whether standard or customised packaging is required. Include your estimated quantity in the inquiry and we will confirm the applicable minimum.

Can I request samples before a bulk order?

Samples can be arranged for evaluation. Standard sample preparation is generally around 3 working days; availability, custom samples and shipping time are confirmed separately. Test the sample on the intended materials before bulk purchasing.

Do you offer colour matching?

Colour matching is available for selected sealant models. We can discuss colour sample cards or a physical sample supplied by you. The final colour should be approved using an actual sealant sample.

What is the production lead time?

The current indication for standard products is around 15 days. The confirmed schedule depends on the product, quantity, packaging and sample approval. OEM production and shipping times are quoted separately.

Can you provide technical documents or certificates?

Tell us the product and destination-market requirements. We will confirm which technical data sheets, safety data sheets or test reports are available for that specific product. Certification and performance claims must be checked against the applicable documents.

Can we arrange a factory visit?

Factory visits are available by appointment. Share your preferred dates, products of interest and inspection requirements so we can coordinate the visit with our family-factory supply team.
