In-stock items: processed and shipped within 1–3 business days. Custom-made items: G/NPT threads and non-standard specifications require 7–15 business days of factory production before shipping.

Standard international delivery typically takes 7–13 business days after dispatch, depending on customs clearance and the local delivery network. Processing or production time is additional. Next-day and overnight delivery are not available.

Most products ship from our manufacturing centers in Asia, then transfer to a local carrier after customs clearance.

Free shipping: orders of US$30 or more weighing under 2 kg. Import duties and taxes are included on all orders.

If an overweight shipping surcharge applies after packing, we pause shipment and email you the amount for approval before dispatch. This is a transport charge, not an import tax. If you do not reply within 7 days, the order is canceled and fully refunded.

Please check the full model number, dimensions, thread type, stroke and voltage where applicable before ordering. If you are unsure, email airtacs@airtacs.com with the model number and required specifications.

Custom-made products, including G/NPT thread specifications and custom-built parts, are non-returnable and non-refundable under our refund policy.
