Shipping liquids requires an understanding of USPS guidelines and restrictions, including which items USPS classifies as liquids. We\u2019ll give you all the basics of shipping and packaging liquids as well as how Stamps.com helps you in the process.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-what-are-liquids\">What are liquids?<\/h2>\n\n\n\n<p>Before we get started, let\u2019s define the type of products we\u2019re referring to. Alcohol <a href=\"https:\/\/www.usps.com\/ship\/shipping-restrictions.htm\" target=\"_blank\" rel=\"noreferrer noopener\">can\u2019t be shipped<\/a> with USPS, so we\u2019re only referring to non-alcoholic liquids. Additionally, the following types of liquids can\u2019t be shipped:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Flammable liquids&nbsp;<\/li>\n\n\n\n<li>Hazardous liquids&nbsp;<\/li>\n\n\n\n<li>Liquids with an <a href=\"https:\/\/pe.usps.com\/text\/pub52\/pub52c4_017.htm\" target=\"_blank\" rel=\"noreferrer noopener\">\u201cobnoxious odor\u201d&nbsp;<\/a><\/li>\n<\/ul>\n\n\n\n<p>On the flip side, creams and pastes are considered liquids and can be shipped through USPS. You\u2019ll just need to follow the same guidelines as the ones listed above. Liquids, creams, and pastes with push-down tops also need to be mailed using \u201c<a href=\"https:\/\/pe.usps.com\/text\/pub52\/pub52c4_017.htm\" target=\"_blank\" rel=\"noreferrer noopener\">strong and securely sealed outer packaging<\/a>.\u201d Push-down tops can potentially open in transit, leading to the damage of other shipments and USPS equipment, so extra precautions need to be taken.&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-international-liquid-shipping-restrictions\">International liquid shipping restrictions<\/h2>\n\n\n\n<p>If you plan to <a href=\"https:\/\/www.usps.com\/international\/shipping-restrictions.htm\" target=\"_blank\" rel=\"noreferrer noopener\">ship liquids internationally<\/a>, there are a few restrictions to keep in mind. The following items can\u2019t be shipped with USPS to international destinations:&nbsp;<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Nail polish&nbsp;<\/li>\n\n\n\n<li>Gasoline&nbsp;<\/li>\n\n\n\n<li>Aerosols&nbsp;<\/li>\n\n\n\n<li>Perfume containing alcohol&nbsp;<\/li>\n\n\n\n<li>Flammable or combustible paint*&nbsp;<\/li>\n<\/ul>\n\n\n\n<p>*<em>Note: Water-based or Latex-based paints can be shipped internationally, as long as they don\u2019t contain <a href=\"https:\/\/blog.stamps.com\/2023\/04\/27\/usps-hazmat-label-update\/\" target=\"_blank\" rel=\"noreferrer noopener\">hazardous materials.<\/a>&nbsp;<\/em><\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-tips-for-shipping-liquids-nbsp\">Tips for shipping liquids&nbsp;<\/h2>\n\n\n\n<p>Regardless of size, USPS requires packages containing liquids to be labeled on the outer packaging and to include orientation labels to show how your package should be handled. For liquids over 4 ounces, you\u2019ll need to triple-wrap your shipment.&nbsp;<\/p>\n\n\n\n<p>To triple-package your shipment, place your product in a leak-proof container that covers the original packaging. Then, place the container in a box, like a <a href=\"https:\/\/www.stamps.com\/usps\/priority-mail-flat-rate\/\" target=\"_blank\" rel=\"noreferrer noopener\">Priority Mail Flat Rate\u00ae Box.<\/a> It also doesn\u2019t hurt to fill the gaps in-between with absorbent materials. If you\u2019re shipping liquids in glass or breakable containers, it\u2019s best to add extra cushioning materials within the gaps of the box and around your products.&nbsp;&nbsp;<\/p>\n\n\n\n<h2 class=\"wp-block-heading\" id=\"h-shipping-liquids-with-stamps-com-nbsp\">Shipping liquids with Stamps.com&nbsp;<\/h2>\n\n\n\n<p>Your customers are eagerly waiting for their drinks, makeup, and other products.
