FAQ - Shipping and Returns

NECi ships all enzyme reagents, test kits, and related products with care to ensure they arrive in optimal condition. Our default carrier is UPS, and most orders are shipped via UPS 2-Day Service. Shipping costs are calculated automatically at checkout based on destination, package weight, and any required temperature-controlled materials.

Yes. We recognize that many laboratories and institutions have established logistics preferences. We can accommodate alternative shipping services, including customer corporate or institutional shipping accounts, upon request. Contact us before placing your order to arrange this.

Yes. For specialized instructions — such as specific delivery windows, temperature-control requirements, or custom packaging — please contact us directly before placing your order. Our team will ensure proper handling and timely delivery according to your laboratory's requirements.

Shipping insurance is automatically included on all orders over $100.00. If you would like insurance coverage on a lower-value shipment, you may request this when placing your order.

Every NECi reagent, enzyme preparation, and test kit is manufactured under stringent quality control procedures to ensure accuracy, reproducibility, and long-term reliability. We guarantee that all NECi products will maintain full functional performance for the durations below when stored under appropriate conditions:

Storage temperature — Guaranteed shelf life
-80°C — 3 years or longer
-20°C — 1 year
4°C — 6 months

These specifications are based on extensive internal validation, accelerated aging studies, and decades of field use across regulated laboratories, research institutions, environmental monitoring programs, and industrial QA/QC operations.

If any product fails to meet these performance standards, we will replace it or provide a refund.

Contact us before returning anything. Our team may be able to resolve the issue immediately — many performance questions are related to storage conditions or procedural steps that we can help troubleshoot quickly. If the product is found to be defective or fails to meet our quality guarantee, we will arrange a replacement or refund.

We rarely accept physical returns. Once a shipment leaves our facility we cannot guarantee the integrity of any product that is returned to us — and we would never resell or reuse a returned item.

What we do instead: replacement

If there is a problem with your order — damaged shipment, incorrect item, or suspected product issue — please contact us and we will make it right. In most cases, we will ship a replacement at no charge.

Reporting damage at delivery

If your package arrives visibly damaged, please document it before opening: photograph the outer packaging, then the contents, before discarding any materials. This documentation helps us file a carrier claim on your behalf and speeds up resolution.
