Walk the pet aisle of almost any Aldi store and you will find something a conventional supermarket rarely shows: a single dog-food SKU, one cat-litter brand, one supplier behind each. That is not a gap in assortment — it is the entire Aldi thesis. Because the group runs only one supplier per item, the company that wins a listing does not share the category; it owns it, across tens of millions of shopping trips a week. For a pet-food or pet-supplies exporter, Aldi is therefore less a customer than a high-stakes, winner-takes-all partnership.
A Discount Dynasty Built on Own Brands
The Aldi story begins in 1913, when the Albrecht family opened a grocery store in Essen, Germany. The “ALDI” name itself only appeared in 1961, the year the business split into two legally separate groups — Aldi Nord and Aldi Sud — run by the heirs of brothers Karl and Theo Albrecht through separate family trusts to this day. The group remains privately held, and that ownership structure underwrites the long-term, margin-disciplined thinking Aldi is known for.
Scale is extraordinary. Combined revenue reached roughly €112 billion in 2023, and the two divisions together operate somewhere between 13,200 and 13,500 stores across 18 countries, employing about 400,000 people. Aldi Sud runs 6,700-plus stores and Aldi Nord 5,500-plus, with the United States and United Kingdom as the largest Anglophone beachheads.
| Division / Region | Approx. Store Count |
|---|---|
| Aldi Sud (global) | 6,700+ stores |
| Aldi Nord (global) | 5,500+ stores |
| Aldi US | 2,547 stores (2025) |
| Aldi UK | ~1,060 stores (target 1,500) |
| Aldi China | 100+ stores (mainly Shanghai) |
The 1,400-SKU Machine
A typical Aldi store carries only about 1,400 to 2,000 stock-keeping units, against the 20,000 to 30,000 found in a conventional supermarket, and roughly 90% of those are owned brands rather than national labels. Each category is served by a single supplier for each item, so the supplier that secures the listing captures the full volume for that product. Goods arrive in their original shipping cartons and are placed directly on the shelf — “out of the box” — which strips out labour and handling cost. The result is a relentlessly low-cost model in which price is the headline and national brands are the exception.
Because Aldi buys with such concentration, it negotiates hard and bakes annual cost-down mechanisms into its supplier contracts. Suppliers are expected to deliver year-on-year efficiency, and the lean in-store labour model rewards products that are easy to merchandise and transport. For a pet supplier, that means a private-label pet line that wins an Aldi listing can become a category-defining volume programme almost overnight — but it also means margin must be defended through manufacturing efficiency, not price increases.
Heart to Tail and the Pet Aisle
Pet sits at the core of Aldi’s owned-brand strategy. The retailer sells food, treats and accessories under its Heart to Tail private label, covering dogs and cats across dry food, wet food, snacks and basic accessories. Aldi’s value-seeking customer base is highly receptive to affordable pet nutrition, and the chain’s “always low price” promise maps neatly onto the value tier of the pet-food market.
For exporters there are two routes in. The first is direct private-label supply — manufacturing Heart to Tail or market-specific Aldi pet brands to strict specification. The second is supplying accessories, chews, toys, grooming tools and seasonal pet items that fit Aldi’s limited but fast-selling non-food ranges. Because Aldi rotates its range far less aggressively than a pure variety-discounter such as Action, pet suppliers that get listed can rely on longer production runs and more stable forecasts, which supports better factory utilisation.
What It Takes to Win an Aldi Listing
Aldi’s compliance bar is high and non-negotiable. Pet-food suppliers must meet the regulatory and feed-safety requirements of each market — FDA/AAFCO in the United States, FEDIAF and EU feed law in Europe — with full ingredient traceability, while non-food pet items carry the relevant CE and REACH markings. On the social side, Aldi expects BSCI- or Sedex-aligned audits and a demonstrable code of conduct covering labour, safety and environmental standards.
Beyond certification, suppliers need genuine private-label capability: the ability to manufacture to Aldi’s specification, pack under its brand, and protect recipe and design confidentiality. With single-source category buying, a stockout is treated as a serious failure, so robust capacity, contingency planning and short, dependable lead times are essential. Aldi buys through national and regional teams — Aldi US, Aldi UK, Aldi Sud international — and a credible approach targets the relevant country buying office with a finished private-label proposal, compliance documentation and proven food-safety or manufacturing certifications. A track record supplying other hard discounters counts for a lot.
The 2024-2026 Growth Surge
Aldi is not standing still. Aldi US recorded an estimated USD 54.16 billion in 2024 sales, up 14% according to NRF and Kantar data, and operated about 2,547 stores across 39 states in 2025. A roughly USD 9 billion US expansion programme is underway, targeting more than 3,000 US stores by 2028 and including the conversion of hundreds of former Winn-Dixie and Harveys Supermarket locations acquired from Southeastern Grocers.
Leadership signalled continuity of that aggressive strategy in 2025 when long-serving US CEO Jason Hart moved to Group COO of Aldi Sud and Atty McGrath became CEO of Aldi US. On the technology front, Aldi partnered on generative-AI product content in 2025 and advanced its S/4HANA and supply-chain transformation to support scale. In the UK, the group continues to pressure incumbents such as Tesco and Sainsbury’s from a base of around 1,060 stores with a 1,500-store target, while sustaining double-digit store growth across multiple regions.
The Pet Supplier’s Playbook
Aldi is a winner-takes-all account: the supplier that secures a private-label pet listing owns the entire category volume for that item, but the bar is high and the price pressure is constant. Pet-food manufacturers with feed-safety certification, recipe-development capability and low-cost production should treat Aldi as a strategic private-label partner, while pet-accessory and treat makers should prepare compliance packages and pitch value-priced, easy-to-merchandise items to the relevant national buying team.
In practice that means securing market-specific pet-food regulatory approvals and traceability systems first, building a private-label development team that can match Aldi’s specifications, investing in BSCI/Sedex social compliance, and designing cost out of the product so annual price-downs remain absorbable. The supplier that then approaches the correct country buying unit with a complete, proven proposal does more than win one listing — it earns a reference that opens doors across the entire global discount sector.
