Shipping Policy
PK Research Labs shipping policy: processing times, secure packaging, domestic and international shipping, carrier tracking, and delay handling details.
Last updated August 9, 2026.
We know waiting on an order is the least fun part of ordering — here’s exactly how we handle processing and shipping so there are no surprises. This is our general policy for standard retail orders; institutional and wholesale orders may follow separate arrangements confirmed at the time of purchase.
Processing Time
Orders are typically processed within one to two business days of payment confirmation, excluding weekends and holidays. Processing time refers to the time between order placement and shipment, and is separate from carrier transit time. Orders placed after our daily order cutoff are processed on the next business day. During periods of high order volume, processing time may be extended, and any delay beyond our standard window will be communicated by email where possible.
Secure Packaging
Orders ship in packaging designed to protect the material in transit, including insulated or temperature-controlled packaging where a product’s storage requirements call for it. Shipping labels and included documentation identify the shipper and order number per standard commercial carrier requirements.
Domestic Shipping
Domestic orders ship via standard commercial carrier service. Available shipping speeds and associated costs are presented at checkout based on the delivery address and order contents. Estimated delivery windows shown at checkout are carrier estimates, not guarantees.
International Shipping
Where international shipping is offered, it is limited to destinations where we are able to ship in compliance with applicable export and import regulations. International orders may be subject to customs review, import duties, or taxes assessed by the destination country; these charges are the responsibility of the recipient and are not included in our shipping charges. Customs processing can extend delivery time beyond standard carrier estimates, and we are not able to guarantee customs clearance timelines.
Carriers
We ship using established commercial carriers selected for reliability and tracking capability. The specific carrier used for a given order depends on destination, package characteristics, and service level selected at checkout.
Order Tracking
Once an order ships, a tracking number is emailed to the address on file and made available in the customer’s account order history. Tracking detail and update frequency depend on the carrier and service level used.
Delays
While we aim to meet the processing and transit estimates provided at checkout, shipping is subject to factors outside our control, including carrier delays, weather, customs processing, and other disruptions. We are not liable for delivery delays caused by the carrier or by circumstances outside our reasonable control, though we will assist in tracking down a delayed shipment on request.
Shipping Errors
If an order arrives damaged, incomplete, or does not match what was ordered, contact support within a reasonable time of delivery with your order number so we can investigate and resolve the issue.
