Manta provides samples of standard products to support your formulation development and quality verification. Please send your sample request to our sales team including:

• ▸ Product code of interest
• ▸ Intended application or formulation
• ▸ Quantity needed
• ▸ Shipping address with recipient contact information

Standard product samples typically ship within 3 business days. Custom or R&D samples may require 1 to 3 weeks depending on formulation complexity.

Standard product samples up to 200 g are provided free of charge for formulation evaluation. Sample quantities exceeding 200 g, or custom-formulated samples, are billed at standard pricing.

Sample costs may be credited toward subsequent commercial orders -- please confirm with your sales representative at the time of sample request. Shipping costs are typically borne by the customer, using the customer's carrier account (FedEx, DHL, UPS) or prepaid by us and invoiced at cost.

We encourage all customers to conduct in-house evaluation before commercial procurement. For every sample shipment, we provide:

• ▸ Certificate of Analysis (CoA) for the specific batch
• ▸ Technical Data Sheet (TDS)
• ▸ Safety Data Sheet (SDS)

If you need third-party certification or specific test reports, please discuss with your sales representative -- we can often arrange independent verification at cost.

We take performance concerns seriously. If a product does not meet the specifications on its TDS or underperforms in your formulation, please contact us immediately with:

• ▸ Batch number and CoA
• ▸ Formulation details (as much as you can share)
• ▸ Description of the performance issue
• ▸ Test conditions and equipment used

Our technical team will review and work with you to identify the root cause. Where a specification deviation is confirmed on our side, we will replace the material or issue a credit note per our sales terms.

Note: performance outcomes in finished formulations depend on many variables (dosage, mixing conditions, substrates, curing conditions, ambient temperature). We encourage early communication so our application engineers can help troubleshoot.

Mixed orders (multiple products in one shipment) are welcome. Please contact sales with your target quantities for a specific lead-time commitment.

Yes. Manta accepts OEM / private-label orders. Please share the following details to initiate the process:

Selecting the best grade depends on your specific formulation system. To provide a meaningful recommendation, our technical team will typically ask:

Based on your inputs, we'll propose 1 to 3 candidate grades, provide comparative TDS data, and ship samples for evaluation. Our application engineers are available to discuss formulation questions via email.

Yes. We provide the following documentation with all commercial orders (and upon request for samples):
