Refunds & replacements
BlackSeaChem EOOD · Last updated April 4, 2026
BlackSeaChem EOOD is a distribution partner in Bulgaria.
Custom research materials have limited reusability. This policy explains how BlackSeaChem EOOD handles quality issues, returns, and refunds for B2B customers.
1. Quality and non-conformance
If a batch fails agreed release criteria documented on the certificate of analysis, notify us within ten business days of delivery with batch numbers, storage conditions, and supporting data. We may request samples or third-party verification. Confirmed non-conformance remedies may include replacement, credit note, or refund at our discretion.
2. Custom synthesis
Custom programs are generally non-cancellable after material procurement or synthesis start unless we agree otherwise in writing. Deposits cover committed capacity and may be forfeited on late cancellation.
3. Catalog items
Unopened catalog SKUs in original packaging may be eligible for return credit within fourteen days of delivery, subject to restocking fees and stability verification. Opened or temperature-compromised items are not returnable.
4. Regulatory or import blocks
If a shipment is refused or destroyed due to incorrect importer documentation provided by the customer, refunds are not guaranteed; salvage or re-shipment may be quoted separately.
5. Process
Email r.atanasov@blackseachem.com with your PO reference, lot ID, and a concise description. We aim to acknowledge within two business days and propose a resolution pathway.
