ID-300 Multivitamin Liquid Emulsion: OEM Buyer Brief

A multivitamin is often the first daily-use SKU in a private label pet nutrition line, which makes the label declaration and the cost per day more important than the headline vitamin count. This brief sets out what the ID-300 page states, how it sits next to ID-130, and which details a buyer still has to obtain in writing.

What the product page lists

ID-300 sits in the BoCui 300 Series and is described as a multivitamin liquid emulsion for dogs and cats of all ages. The health direction on the page is daily nutrition and general wellness, and the key ingredients are given as two groups: water-soluble vitamins and fat-soluble vitamins, 11 key vitamins in total. Net content is 80 ml per bottle, usage is 1 ml per 4 kg body weight twice daily, mixed with feed or given directly, and shelf life is listed as 2 years.

What the page does not publish matters just as much: it does not name the 11 vitamins individually, does not give an amount per ml for any of them, and does not include a specification sheet. Any label or ingredient declaration you prepare should keep those fields marked as pending until the factory confirms them in writing.

Why the fat-soluble and water-soluble split matters to a buyer

Carrying both vitamin groups in one liquid is the practical reason the product is an emulsion rather than a simple solution: fat-soluble vitamins need an oil phase, water-soluble vitamins sit in the water phase. For a buyer that raises three questions. Does the emulsion stay uniform across the stated 2-year shelf life, and what stability data supports that figure? Is the label amount declared at manufacture or at end of shelf life? And should the bottle carry a shake-before-use instruction? None of these are answered on the product page, so they belong on your written question list. The liquid formats guide explains how emulsions differ from oral solutions and gels.

ID-300 or ID-130 for a skin and coat shelf

Both products sit in the Skin & Coat range, but the pages describe them differently. ID-130 is in the Liquid Series and names multivitamins, omega fatty acids, zinc and biotin, with the same 1 ml per 4 kg twice-daily usage and 2-year shelf life; its page does not publish a net content. ID-300 is a vitamin-focused emulsion with an 80 ml bottle listed. A brand that already sells a fish oil product such as EM-300 may want to avoid overlapping omega claims across two SKUs, while a brand building a single all-in-one coat product may look at ID-130 first. For a vitamin-led daily line, IM-300 in the immune and daily nutrition range is the other liquid to compare.

The cost-per-day arithmetic

The published usage line works out to 0.5 ml per kilogram per day. A 4 kg cat takes 2 ml a day, so one 80 ml bottle covers 40 days. An 8 kg dog takes 4 ml a day for 20 days, a 16 kg dog takes 8 ml for 10 days, and a 32 kg dog takes 16 ml a day, covering 5 days. These are arithmetic on the published dose, not feeding advice, but they show why a single 80 ml bottle suits a cat or small-dog line far better than a large-dog line. The pack size guide and the label dose table guide cover how to turn this into a pack choice and a weight table.

What to confirm before ordering samples

Ask the factory in writing for the list of the 11 vitamins with the declared amount per ml, the basis of the 2-year shelf life, whether pack sizes other than 80 ml are available, whether the formula can be adjusted for flavour, and which documents ship with each batch. The COA and specification sheet guide explains what those documents should contain.
