This page explains how orders are processed, packaged, and shipped, with specific guidance for temperature‑sensitive, hazardous, and compliance‑restricted materials. It’s written for trained researchers and institutional buyers; it does not provide medical or clinical advice.

Order processing and dispatch

• Cut‑off times: Orders approved before the daily cut‑off are queued for same‑day processing; later orders roll to the next business day.
• Lead times:
  • In‑stock items: Typically dispatch within 1–2 business days.
  • Custom or specialty forms: May require additional lead time; we’ll confirm by email.
• Verification checks: Age/institutional eligibility and compliance review may be required prior to release; orders may be held pending documentation.
• Backorders: If an item is backordered, we’ll provide an ETA and offer split shipments or a full order hold per your preference.

Packaging standards

• Primary containment: Chemically compatible containers with tamper‑evident seals and lot‑specific labeling.
• Secondary containment: Spill‑resistant trays or sealed bags for liquids/solids; shock‑absorbing materials to protect fragile items.
• Temperature control: Insulated shippers with coolant (e.g., gel packs) for 2–8°C items; dry-ice shippers for below-freezing requirements when applicable.
• Light and moisture protection: Amber glass or light‑blocking wraps for photolabile materials; desiccants and moisture indicators for hygroscopic items.
• Documentation inside: Packing slip; lot numbers; storage quick‑guide; links/QR to CoA and SDS where applicable.

Shipping methods and timing

• Service levels:
  • Standard ground: Cost‑effective for ambient‑stable products.
  • Expedited air: Preferred for time‑sensitive or temperature‑controlled items.
  • Cold‑chain: Scheduled to avoid weekend holds; may require a signature.
• Dispatch days: Business days only. Sensitive shipments are timed to minimize in‑transit dwell (e.g., avoid Friday dispatch for 2–8°C items).
• Tracking: You’ll receive a tracking link upon carrier handoff; updates include out‑for‑delivery and exception notices.
• Signature requirements: May be mandatory for restricted, high‑value, or temperature‑controlled shipments.

Address, delivery, and special cases

• Address validation:
  • Requirement: Provide a complete physical address; PO Boxes may be restricted for certain classes.
  • Corrections: Contact support promptly if you spot errors; rerouting after dispatch may incur fees.
• Delivery attempts: Carriers typically make multiple attempts; unclaimed packages may be returned to sender.
• Institutional receiving: Include department, building, and receiving hours to prevent delays; notify receiving of any cold‑chain arrivals.

Cold‑chain guidance

• Pre‑delivery notice: We’ll aim to notify you before cold‑chain shipments arrive; ensure staff and storage are prepared.
• On receipt:
  • Inspect promptly: Check insulation integrity, coolant condition, and container seals.
  • Store immediately: Place materials into recommended conditions (e.g., 2–8°C, −20°C) per CoA/SDS.
• Evidence of excursion: If you suspect a temperature excursion, document with photos and any logger data; contact QA before opening.

Hazardous and compliance‑restricted materials

• Hazmat declarations: Certain items ship with hazardous classifications; carriers and service levels are chosen accordingly.
• Jurisdictional restrictions: Availability and methods may vary; orders that fail compliance checks may be canceled or require additional documentation.
• Buyer responsibilities: Ensure lawful procurement, possession, and use in your location; provide import permits or licenses when required.

International shipping and customs

• Documentation: Commercial invoice, HS codes, and any requested certificates included; provide local regulatory paperwork when necessary.
• Duties and taxes: Assessed by your local authority and typically due at delivery; these are not included in product prices unless stated.
• Customs delays: We’ll monitor progress and assist with inquiries; timelines can vary based on local processing.
• Returns refused by customs: Assessed case‑by‑case; duties/fees are generally non‑refundable.

Loss, damage, and claims

• On arrival:
  • Inspection: Photograph package and contents, including seals and labels.
  • Report window: Contact support promptly with order number, tracking ID, and photos.
• Damaged shipments: We coordinate with the carrier and assess replacement/refund eligibility after claim review.
• Lost shipments: If tracking stalls or shows delivered but unreceived, we’ll open an investigation with the carrier and advise next steps.
• Insurance: High‑value shipments may include additional coverage; file claims through our support team.

Returns and refusals

• Standard returns: Only eligible for unopened items with RMA authorization; see the Refund and Returns Policy for details.
• Refused deliveries: Refusals without prior agreement may result in restocking fees and return freight charges.
• Quality incidents: If you suspect a deviation, contact QA instead of refusing—investigation and remedy are handled via our quality process.

Notifications and communication

• Order updates: Confirmation, dispatch, tracking, and exception notices are sent to the account email.
• Cold‑chain alerts: Where possible, pre‑delivery alerts help you prepare receiving and storage.
• Change requests: For address or timing changes, contact support as early as possible; feasibility depends on carrier status.

Buyer checklist for smooth delivery

• Before ordering:
  • Eligibility: Confirm institutional or research qualification.
  • Storage readiness: Ensure proper temperature, light, and moisture controls are available.
  • Receiving info: Provide precise delivery details and hours.
• After dispatch:
  • Track actively: Monitor the carrier link; prepare receiving staff for arrival.
  • Inspect and store: Photograph seals; store per CoA/SDS; log the opened date.

Scope and safety

• Research‑only: Materials are for lawful laboratory research; do not ingest or administer under any circumstances.
• No clinical advice: This page provides logistics and handling context only; consult institutional policies and your safety office for specific requirements.
