Donkey-hide gelatin

High-quality Ejiao should be dark brown to blackish-brown, translucent, and brittle with a glossy surface. When broken, the fracture should be shiny and glass-like. A critical test is the smell: when dissolved in boiling water, it should emit a mild, pleasant aroma without any fishy or foul stenches, which indicates the use of pure donkey hides rather than scrap leather or other animal skins.

As a traditional medicine and food supplement, suppliers must possess GMP (Good Manufacturing Practice) certification for production. For cross-border entry, products must meet heavy metal limits (Lead, Cadmium, Mercury, Arsenic) and microbiological safety standards. Buyers should request a Certificate of Analysis (COA) for every batch and ensure the manufacturer is registered with the destination country's food/drug authority, such as FDA (USA) or EFSA (EU) guidelines.

The most reliable method is DNA Barcoding technology to confirm the presence of Equus asinus (donkey) DNA and the absence of bovine, porcine, or equine contaminants. Professional B2B buyers should prioritize suppliers who provide third-party lab reports and have a traceable supply chain from the slaughterhouse to the finished product.

Ejiao is sourced in three primary forms: Solid Blocks (traditional, longest shelf life), Ejiao Powder (for easy mixing into beverages), and Ready-to-eat Cakes (mixed with nuts and sesame). For the health supplement market, Ejiao Oral Liquid is also popular due to its high absorption rate and convenience for modern consumers.

The biggest risk is CITES and animal byproduct regulations. Some countries have strict bans or high tariffs on donkey-derived products to protect local animal populations. Always verify the HS Code (typically 3503.00) with a local customs broker and ensure the supplier provides a Health Certificate and a Certificate of Origin to avoid cargo seizure.

Utilize Trade Terms like CIF or FOB and conduct payments through secure channels. For large orders, it is highly recommended to use Made-in-China.com's secured payment services or an Escrow system. Never wire full payments upfront to unverified accounts; instead, use a 30% deposit and 70% balance payment structure after a successful pre-shipment inspection.

Price is heavily influenced by the purity of the donkey hide and the aging process (aged Ejiao often commands a premium). Negotiate based on volume tiers; for instance, ordering over 500kg can often yield a 10-20% discount. Additionally, ask for packaging customization (OEM) to be included in the unit price to increase your retail margin.

Ejiao is sensitive to high humidity and extreme heat, which can cause the blocks to soften or mold. Ensure the contract specifies cool, dry storage during transit. For long-distance cross-border shipping, use moisture-proof vacuum packaging and consider air freight for high-value concentrated extracts to minimize environmental exposure.
