How to Launch Liquid Supplements on Amazon: Shelf Life, Glass, Hazmat and FBA Prep

FDA's cGMP rule does not require a supplement to carry an expiration date. FDA's small entity compliance guide says plainly that no expiration, shelf or "best if used by" date is required, but if you put one on the label, you should have data to support it (FDA: cGMP Small Entity Compliance Guide). For a liquid sold through FBA, the date is not optional in practice, because Amazon requires every ingestible product to show an expiration or manufacturing date (more on that below). So you need stability data, and you need it before you order labels.

Stability testing means storing finished bottles over time and retesting them to see how long the ingredients hold their labeled amounts. Ask your manufacturer for stability data on your exact formula, bottle and closure, not a similar product.

Water-based liquids usually need a preservative system. A 2019 SupplySide article by a quality consultant names sodium benzoate and potassium sorbate as common synthetic choices and rosemary oil or citric acid as natural ones, and recommends preservative challenge testing, where a lab adds known microbes to the product and measures how fast they die off (SupplySide: Ensuring preservatives are tested in liquid supplements). The same article says that testing can take eight to ten weeks, so start it early. The author runs a quality consulting firm.

Everything in this section is from Amazon's Seller Central help pages as of October 2026. Amazon changes these pages without notice, so confirm in Seller Central before you send your first shipment.

Amazon's liquid products page says the container and its lid decide whether a liquid needs extra prep, and that cap seals, bagging and bubble wrap are the most common prep types (Amazon: Liquid products). Non-hazmat liquids of 4.2 oz (125 mL) or less need no added prep unless the product is repeatedly damaged in transit. Fragile containers such as glass require bubble wrap, and may also need a cap seal if the wrap does not stop leaks. A double seal reduces the need for added prep. Amazon defines it as a tightened lid that cannot be easily opened plus one of these: an induction seal, a safety ring, a plastic wrap band, a child-resistant cap, heat shrink wrap, or a sealed six-sided box that holds the item as sold.

Amazon's fragile products page adds that every fragile unit must be wrapped or boxed individually, with six solid sides or full bubble wrap, and warns that empty space in the package lowers the chance of passing the drop test (Amazon: Fragile products). The drop test is yours to run: five drops from 3 feet onto concrete, hitting the top, bottom, largest side, a bottom corner and the longest bottom edge. Amazon says it does not run this test for you.

Since January 1, 2026, Amazon no longer offers prep and item labeling services for FBA shipments in the US store, according to an Amazon statement quoted by Packaging Insights (Packaging Insights, Oct 2025). So bubble wrap, cap seals and FNSKU labels on liquid units are now done by you, your manufacturer or a prep center before inventory ships. Amazon's pages say non-compliant inventory may be refused, returned or repackaged at your expense.

Alcohol and hazmat. Amazon's examples of possible dangerous goods include essential oils and products with high alcohol content (Amazon: Examples of possible dangerous goods). Amazon says the physical and chemical properties of each finished product decide its classification, so there is no blanket answer for tinctures. If Amazon asks, you upload a safety data sheet or exemption sheet from your manufacturer, and Amazon's dangerous goods guide says you have 14 business days to provide product safety information. Liquids regulated as dangerous goods must be bagged no matter how they are sealed. Ask your manufacturer for the safety data sheet before you create the listing, not after inventory is stuck.

Expiration dates. Amazon treats dietary supplements as expiration-dated products and requires the expiration attributes to be set correctly when the ASIN is created (Amazon: Expiration dates on FBA products). At check-in, a product needs enough remaining shelf life to be used in full plus 90 days. Amazon's own example is a bottle with 240 daily servings, which needs 330 days. A 60-serving liquid taken once a day would need at least 150 days. The same page's guideline table lists herbal or mineral supplements at 730 days, so check which figure applies to your ASIN in Seller Central and plan production so your dates clear the higher number. The date you enter when you create the shipment must exactly match the date printed on the bottle, and Amazon says mismatches can lead to listing blocks, disposal or account deactivation.

Shoppers choose liquids for reasons a listing can show: no pills to swallow, a dose they can adjust, an easy way to mix into water. Use the images to answer the questions a liquid raises. How much is one serving? What does the dropper look like? How do I take it? How long does a bottle last? A simple graphic showing one serving next to the bottle, plus the number of servings per container from the panel, answers most of them.

Set honest taste expectations in the bullets. If it is a bitter tincture, say how to take it in juice or water, and if it needs refrigeration after opening, say so on the label and listing. A short clip of a dropper going into a glass of water explains the format faster than text.

Supplement brands we have worked with include Liquid Health and Purely Optimal. A brand manager can plan these images and clips as one set instead of piecemeal. Our product photography starts at $295 and product video at $395, and the supplement packaging design guide covers how your label and carton choices show up in Amazon images.
