All orders MUST have a US Chrome order form included in each box shipped. Any cylinder received without this form is subject to rejection or delayed servicing. We currently do not take special instructions over the phone, but you can email them directly to sales@usnicom.com.   If you are shipping larger items that require special handling, please ship them in a plastic tote or wooden box to ensure safe shipping. We also recommend you insure the shipment for the value of the item(s) and request a tracking number. US Chrome is not responsible for damage caused by carrier mishandling.
