The short answer
In Mexico, an almacén general de depósito (AGD) is a financial entity: an auxiliary credit organization regulated under the Ley General de Organizaciones y Actividades Auxiliares del Crédito and supervised by the National Banking and Securities Commission (CNBV). It is the only type of company allowed to issue warehouse receipts (certificados de depósito) and pledge bonds (bonos de prenda), and the only one that can operate the customs regime of bonded warehousing (depósito fiscal).
A 3PL — a logistics operator like us — is an operation: it receives, stores, picks and ships your goods. It does not issue warehouse receipts and does not operate bonded warehousing.
Both keep product in a building. That is where the resemblance ends. And confusing them is expensive in both directions: hiring an AGD to fulfill e-commerce orders means paying for a financial instrument you will never use; expecting your 3PL to hand you a warehouse receipt for a bank loan means asking for something it legally cannot issue.
If you are coming from the US, note the difference in structure: a US bonded warehouse is licensed by CBP and can be an ordinary logistics company. In Mexico, the equivalent regime sits inside a supervised financial entity. Same idea, different gatekeeper.
What an AGD does that a 3PL cannot
1. Turn your inventory into a negotiable document
The certificado de depósito evidences ownership of the deposited goods. The accompanying bono de prenda allows a secured credit to be created over those same goods. In practice: you hand product to the AGD, the AGD issues the instrument, and you take it to a bank to borrow against your inventory.
Only AGDs may issue them, and they are liable for the goods those documents cover. The instrument was designed for large inventories of stable value — grain, metals, industrial inputs — not for 800 e-commerce SKUs that turn every three weeks.
2. Operate bonded warehousing
Depósito fiscal is a customs regime. Under article 119 of Mexico's Customs Law, it consists of storing foreign or domestic goods in general deposit warehouses that may provide that service under the LGOAAC and that are additionally authorized to do so by the customs authorities. That is two permits, not one.
What the regime buys is time: goods may stay in bonded warehousing for up to 24 months, with foreign trade taxes assessed but paid on withdrawal, in full or in part. It is identified on the pedimento with key A4 (ANAM).
In plain terms: you import a container, leave it in bonded warehousing, and pay duties as you pull product out to sell, instead of paying everything the day it lands. For an importer with heavy seasonality, that is cash flow.
What a 3PL does that an AGD usually does not
Here is the other side, and the one most people skip. The AGD structure is designed to safeguard and collateralize, not to pick single orders. A warehouse built for e-commerce does things a traditional AGD is not set up for:
| AGD | E-commerce 3PL | |
|---|---|---|
| Nature | Regulated financial entity | Logistics operation |
| Supervised by | CNBV (and SAT on customs matters) | No financial regulator |
| Core document | Warehouse receipt / pledge bond | Tracking number and inventory report |
| Handling unit | Pallet, lot, container | Piece and order |
| Single-order picking | Normally no | Yes — pick and pack |
| Store integration | No | Yes — what actually syncs |
| Consumer returns | No | Yes |
An AGD solves a capital and duty problem. A 3PL solves the problem of getting it to your customer on Tuesday. Those are different problems.
How to choose: three questions
- Do you need to borrow against your inventory? If yes, you need an AGD — and probably a 3PL as well for the operational side.
- Do you need to defer import duties? If you bring in large volume that you will sell over months, bonded warehousing can pay for itself. If you import and sell quickly, the paperwork and cost of the regime can exceed the benefit. Our post on how to read a pedimento helps you identify which regime you are using today.
- Is your problem storing or shipping? If you sell online, your problem is almost always shipping. In that case what you need is an operation, not a financial instrument.
These are not mutually exclusive. An importer with seasonality can keep the bulk in bonded warehousing and move only the quarter's inventory to its 3PL. What does not work is asking one to do the other's job.
How to verify a real AGD
This is the practical part, and the reason the distinction is worth knowing: "almacenadora" and "almacén general" are words anyone can print on a brochure. Being an AGD requires authorization.
- Look it up in the CNBV's registry of supervised entities. If it is not listed, it is not a general deposit warehouse, whatever its trade name says (CNBV).
- For bonded warehousing, also ask for the specific customs authorization. Being an AGD is not sufficient on its own.
- If you are offered a warehouse receipt, ask who issues it and under what authorization. The document has legal effect; it is not a goods-received slip.
Where we stand, without ambiguity
Ecommex is not an almacén general de depósito. We do not issue warehouse receipts or pledge bonds, and we do not operate bonded warehousing. We say it here because this is exactly the kind of detail worth clearing up before signing, not after.
What we do is the operational half: receive your import once released, store it, control it by lot and expiry, and pick order by order for your end customer. Once your product has cleared customs and needs to move, that is where we come in.
FAQ
Can a 3PL hold imported goods? Yes, once the goods are nationalized. What it cannot do is keep them under a suspensive customs regime such as bonded warehousing.
Does bonded warehousing exempt me from duties? No. It defers them. Duties are assessed on entry and paid on withdrawal, updated for the period elapsed.
Can I keep inventory in an AGD and have them fulfill e-commerce orders? Some offer logistics services, but the structure was not designed for single-unit picking. Before assuming it, ask explicitly about handling unit, store integration and returns handling.
If your product is already nationalized and you need a warehouse that controls and ships it, see our warehousing in Mexico service; and if the challenge starts earlier, when the container lands, here is how we support import.
