Where Kiln ships
Kiln ships only to destinations and service levels made available during checkout. Product availability may vary by jurisdiction, product category, carrier, address type, account status, research-access status, payment review, or other legal and operational restrictions. Kiln may decline or cancel an order that cannot lawfully or reliably be fulfilled to the submitted destination.
Processing
Published processing window: 3–5 business days. Processing time is separate from carrier transit time and begins only after the order is accepted and any required payment, account, fraud, inventory, or compliance review is complete.
A tracking number or printed shipping label does not by itself mean a carrier has accepted the parcel. Kiln treats carrier acceptance, in-transit movement, and delivery as distinct events and reports them based on the corresponding fulfillment or carrier data available to Kiln.
Transit and delivery estimates
Standard carrier/service: USPS Ground Advantage. Published transit window: 2–5 business days.
- Standard: 2–5 business days
These service estimates are sent to Stripe Checkout and shown before payment for the shipping methods actually offered. Delivery windows are estimates unless Kiln expressly states that a particular date is guaranteed. Carrier performance, weather, holidays, service disruptions, address issues, security screening, customs processes, and other events outside Kiln's reasonable control may affect arrival time.
Shipping charges
Available shipping methods and charges are shown before authentication in the bag when verified rates are available, and again during checkout. Shipping promotions, thresholds, and service availability may change for future orders. Any shipping charge displayed and accepted at checkout governs that order unless corrected as permitted by the Terms of Service or applicable law.
Address accuracy
You are responsible for providing a complete and accurate delivery address. Contact support immediately if you discover an error. Kiln cannot guarantee that an address can be changed after fulfillment begins, and carrier rerouting may not be available.
Kiln is not responsible for delay, failed delivery, or additional shipping costs caused by an address supplied incorrectly by the customer, refusal of a deliverable shipment, failure to retrieve a held package, or unauthorized forwarding, except where applicable law requires otherwise.
Tracking
Order and fulfillment communications may include a tracking number or tracking link once available. Carrier scans can be delayed or incomplete. Kiln does not represent that every carrier event will appear immediately or that a lack of scanning means the parcel has not moved.
Split shipments
Kiln may fulfill an order in more than one shipment when reasonably necessary because of inventory location, packaging, carrier, product category, or operational requirements. Where this occurs, each shipment may have separate tracking and delivery timing.
Delivery
Delivery status is determined from the available carrier and fulfillment record together with other relevant evidence. If a shipment is marked delivered but cannot be located, follow the steps in the Kiln Resolution Policy and contact support promptly.
Freight forwarders and intermediary addresses
If you choose to ship to a freight forwarder, package forwarding service, hotel, mailroom, temporary address, or other intermediary, Kiln's ability to investigate loss, damage, or mishandling after documented delivery to that intermediary may be limited. Kiln is not responsible for acts or omissions of an intermediary selected by the customer except where applicable law provides otherwise.
Delays, loss, and damaged shipments
If a parcel is materially delayed, appears lost, arrives damaged, or contains a fulfillment error, contact support@shopkiln.com with the order number and checkout email. Kiln may review carrier scans, fulfillment records, packaging evidence, delivery information, and other relevant records before approving a replacement, carrier claim, refund, or other remedy.
A parcel is not automatically considered lost merely because an estimated delivery date has passed or tracking has not updated. Additional rules for claims and remedies appear in the Kiln Resolution Policy.
Restrictions and compliance
Kiln may restrict particular products, quantities, destinations, carriers, or address types where reasonably necessary for law, safety, payment-provider requirements, fraud prevention, product integrity, research-use controls, or operational reliability. No shipping option displayed elsewhere on the site overrides a product-specific or legal restriction.
Relationship to the Terms
This Shipping Policy is incorporated into the Kiln Terms of Service. The Terms control in the event of a conflict unless this policy states a more specific shipping rule. Nothing in this policy limits rights that applicable law does not permit Kiln to waive.
