Rongshengchang (Stored.bio)
A Hainan-registered trading group selling pet food, supplements, care products and connected devices. Import/export and food sales in scope; factory and certificates unverified.
Storefronts, not a plant.
Pet Food — Retail Packs
Dog and cat food in retail packaging, sold through its own storefronts. The category sits under food import rules in most markets, so the importer of record and the registration holder matter as much as the price. Ask which entity holds the registration for the destination market.
Pet Supplements and Care
Nutritional supplements and care items (drops, tablets, topical products) that sit close to veterinary or medicinal rules in many jurisdictions. Nothing in this category should be quoted before the destination registration position is clear.
Connected Devices
Wireless and connected consumer devices. For the United States these require FCC authorisation before sale, and the authorisation has to name the product. Confirm who holds it before quoting a US buyer.
Export and Sourcing Service
The registered scope includes import and export agency, goods and technology import and export, and food sales. That is a trading capability, not a production one; the manufacturer behind each line has to be identified per product.
What the registry confirms, and what stays open.
This Is a Trading Entity, Not a Factory
The registered name is an investment group. Its scope covers import and export agency, goods and technology trade and food sales. No manufacturing clause, plant, production line or capacity figure has been verified. The page therefore describes a trading supplier.
Registration Read, Figures Not
Registration shows the entity established on 5 May 2023 under the Hainan market regulator, status active, credit code 91460000MACHPENEXW. The 20–50 staff and 150-country figures come from the company’s own pages and were not verified; the 2025 annual report shows zero insured staff, which is a different measure and worth asking about.
Several Storefronts, One Entity
Products are sold through more than one domain. Before ordering, confirm which entity contracts, issues the invoice and handles export for the specific storefront you are buying from.
Regulated Categories Need Registration
Pet food, supplements and topical care products each carry destination-market registration or notification duties; connected devices carry radio authorisation. None of these documents has been sighted for any specific product.
Manufacturer Identity Is the Open Item
For every line, the producing factory is unidentified in the material reviewed. A buyer should require the manufacturer name, address and any audit or certificate for that site before treating this as a supply relationship.
What was checked — and what the check found.
This listing records a registered trading entity and the product categories it sells. No factory, certificate or product registration has been verified. No verification badge is awarded.
A registered trading group, described as one.
Rongshengchang (Stored.bio) is the English listing name used here for 融盛昌投资集团（海南）有限责任公司, a Hainan-registered investment group established on 5 May 2023. Its recorded scope covers import and export agency, goods and technology trade, and food sales.
It sells pet food, supplements and care products, and connected devices, through its own storefronts. It does not present itself as a factory owner, and no plant, production line or capacity figure has been verified for this listing.
That is the honest shape of this entry: a trading counterparty with a regulated product mix. The first questions are which entity contracts and exports, who manufactures each line, and which registration or authorisation the destination market requires.
Registered in Hainan, since 2023.
Entity registered
Established 5 May 2023 in Hainan, status active, with import and export and food sales in scope.
Report and listing reviewed
Products, storefronts and the company’s own scale statements were reviewed for this listing; no factory document was supplied.
Factory and documents
Manufacturer identity, product registration and certificates remain open for every line.
Pick a line and a market
Choose the category and destination, then obtain the registration position and the manufacturer for that product.
What a buyer has to pin down first.
Importers Testing a Pet Range
Start with the category and the destination registration position, then the manufacturer behind it. Melamine-style price comparison before registration is settled wastes both sides’ time.
Distributors Adding Connected Devices
Radio authorisation and labelling are the gate, not the price. Ask who holds the authorisation and whether the product can be sold under your brand in your territory.
Brands Looking for a Sourcing Partner
If what you need is sourcing and export handling rather than manufacturing, this is a plausible partner type — provided the manufacturer and the documents are disclosed per order.

Frequently Asked Questions
Is Rongshengchang a manufacturer?
No. It is a Hainan-registered investment group whose recorded scope covers import and export agency, goods and technology trade and food sales. No manufacturing clause, plant or capacity document has been supplied, so it is listed as a trading supplier.
What products does it sell?
Pet food in retail packaging, pet supplements and care items, and connected consumer devices, sold through its own storefronts. The manufacturer behind each line still has to be identified.
Which documents should a buyer request?
For pet food and supplements, the destination registration or notification; for devices, the radio authorisation; in every case the manufacturer name and address, and the entity that will invoice and export.
The site says 20–50 staff and 150 countries — is that verified?
No. Those figures are the company’s own statement. The 2025 annual report shows zero insured staff, which measures something different; ask the company to explain the gap before relying on scale claims.
Can it export and invoice directly?
Import and export are in the registered scope, but confirm in writing which entity contracts, issues the invoice and handles customs for your specific order, since several storefronts are involved.
Talk to Rongshengchang (Stored.bio) directly.
Send the product category, the destination market, the volume and whether you need the supplier to hold the registration or the brand owner to. Ask which entity issues the invoice and handles the export, who the actual manufacturer is, and for the product registration or test documents the destination requires.
