Shipping Policy

Helm Compounds ships all orders from California once payment has cleared. Order processing happens on business days and does not include weekends or U.S. federal holidays.

Orders that clear payment by 3:00 p.m. Pacific on a business day ship the same day. Orders that clear after that time, or on a weekend or U.S. federal holiday, ship the next business day. Because dispatch follows payment rather than order placement, an order paid by a method that settles manually ships once that payment is confirmed.

Shipping options and the cost of shipping are shown at checkout before you complete your order. Shipping is charged at a flat rate per order, so the price does not change with order size. Delivery estimates shown there come from the carrier and are not guaranteed.

Helm Compounds ships within the United States only, to the 50 states and the District of Columbia. We do not ship to U.S. territories, including Puerto Rico, Guam, the U.S. Virgin Islands, American Samoa and the Northern Mariana Islands, and we do not ship to APO, FPO or DPO military addresses. We do not ship internationally.

Expedited two-day service is not available to Alaska or Hawaii. Orders to those two states are offered standard service and a priority service in its place, both shown at checkout.

You are responsible for entering an accurate, deliverable shipping address at checkout. If a package is delayed, returned, or lost because the address was incorrect or incomplete, you are responsible for the cost of reshipment.

All products are sold and shipped for laboratory research use only. You are responsible for complying with any requirements that apply to receiving this type of product in your jurisdiction.

If tracking has not updated in a while, or a package shows as delivered but you have not received it, contact us at support@helmcompounds.com with your order number so we can look into it.

Most delivery issues trace back to the carrier rather than to us, so we will help you open an investigation with them and provide any information they request. Carrier investigations take time to resolve and we cannot promise a specific outcome or timeframe.

Report a missing or delayed package as soon as you notice it. The sooner an investigation starts, the sooner it can be resolved.

All sales are final. We do not issue cash refunds, with one exception described below.

If an item arrives damaged or broken, report it to support@helmcompounds.com within 7 days of delivery along with photographs of the item and its packaging. We will resolve verified claims by reshipping the item or issuing store credit, at our discretion, and never as a cash refund.

Orders cancelled before they ship are refunded in full.

Full detail, including how store credit works, is set out in our Refund Policy.

Email us at support@helmcompounds.com with any shipping question. Our support hours are Monday through Friday, 9:00 a.m. to 5:00 p.m. Pacific Time, excluding U.S. federal holidays, and we aim to respond within one business day.
