AliExpress Has Its Own Rules. Learn Them Before They Cost You
Processing times, ePacket, dispute windows, supplier tiers, escrow, sourcing from AliExpress looks straightforward until it isn't. The platform runs on its own logic, and one misread term can mean a late order, a lost dispute, or a supplier relationship that quietly falls apart. This glossary maps out the AliExpress seller and buyer vocabulary so you know exactly what you're agreeing to, who you're working with, and what your options are when things don't go to plan.
What is Choice?
AliExpress's curated product programme — a label applied to listings that meet AliExpress's quality, shipping speed, and supplier reliability standards, typically fulfilled from AliExpress-managed or partner warehouses.
Why it matters: Choice listings offer faster and more predictable delivery than standard supplier listings — often with free returns and expedited fulfilment. For sellers who prioritise delivery consistency over supplier flexibility, sourcing from Choice-listed products reduces the variability that damages customer satisfaction scores.
What is Escrow?
AliExpress holds the buyer's payment in a protected escrow account and only releases it to the supplier after the buyer confirms delivery, or after the dispute window expires without a complaint.
Why it matters: This is your financial safety net. It means suppliers don't get paid until the transaction is considered complete. If something goes wrong — wrong item, non-delivery, quality issue — the escrow system is what gives you leverage to dispute and potentially recover your money.
What are Store Coupons / Select Coupons?
Discount codes issued by individual AliExpress suppliers (Store Coupons) or by AliExpress itself during promotional events (Select Coupons) that reduce the order cost at checkout.
Why it matters: Smart sourcing includes stacking available coupons against your supplier orders to improve margins without negotiating directly with suppliers. During major AliExpress sale events — 11.11, 3.28, etc. — Select Coupons can generate meaningful cost reductions on bulk sourcing runs.
What is Dropshipping Center?
A built-in, free analytics tool provided by AliExpress. It helps you analyze product trends, search for hot-selling items, and find suppliers that offer direct dropship discounts.
What is DS Center (Dropshipping Center)?
A free tool developed by AliExpress, primarily used to search for products and locate suppliers for products not currently available on AliExpress.
Why it matters: The easiest way to activate it is to go directly to ds.aliexpress.com, log in with your AliExpress account, and accept the terms. Inside, you get product trend data, supplier ratings, sales velocity signals, and a reverse image search — all free tools that replace hours of manual sourcing research.
What is DSers?
The official AliExpress solution designed to streamline seller operations — offering access to an extensive product catalogue, integration with Shopify and WooCommerce, automated order tracking synchronisation, real-time order status updates, stock management, variant mapping, bundle product options, and bulk purchasing capabilities.
Why it matters: DSers replaced Oberlo as the go-to AliExpress order management tool. It is the most direct bridge between your store and your AliExpress suppliers — automating the fulfilment loop that would otherwise require constant manual intervention.
What are DS Levels?
An exclusive discount scheme that rewards sellers with price reductions depending on total spend on orders. The loyalty programme has 4 levels: Normal, C, B, and A. Sellers start from Normal and advance as they continue increasing sales.
Why it matters: The levels programme is a discount-for-volume programme — it is free to join and you join automatically once you sign up to the DS Center. A 2% reduction begins at Level C, with deeper discounts at B and A. At scale, even a 2% reduction on supplier costs meaningfully improves your overall margin.
What is the AliExpress API?
The technical interface that allows third-party tools and platforms — DSers, Shopify apps, custom order management systems — to connect directly to AliExpress and automate product imports, order placements, and tracking updates.
Why it matters: The API is what makes automation possible at scale. Without it, every product listing, order, and tracking update would require manual handling. Sellers building or using tools that connect to AliExpress via API can process hundreds of orders with the same effort it would take to manually process ten.
What is Buyer Protection?
AliExpress's guarantee programme that covers every order for a defined period — typically 90 days from order placement — protecting buyers against non-delivery and items significantly not as described.
Why it matters: Buyer Protection is the safety net underpinning every AliExpress transaction. As a seller sourcing through AliExpress, understanding its terms means you know exactly how long you have to raise a complaint, what evidence is required, and what outcomes are possible. Missing the protection window means losing your claim regardless of how clear-cut the case is.
What is a Dispute?
A formal complaint raised through AliExpress's resolution system when an order goes wrong — covering non-delivery, items not as described, damaged goods, or seller non-responsiveness.
Why it matters: The dispute system is your primary financial protection on AliExpress. It holds supplier payment in escrow and gives you leverage to claim a refund or replacement when fulfilment fails. Knowing the dispute window — typically 15 days after confirmed delivery — and acting within it is the difference between recovering your money and absorbing the loss.
What is Bolo?
An AliExpress community and seller resource platform — essentially an information hub where sellers can access guides, tips, and updates related to AliExpress sourcing and selling practices.
Why it matters: Bolo is where AliExpress publishes platform updates, policy changes, and seller education content. Staying aware of its content helps you catch changes to shipping methods, supplier programmes, or platform rules before they affect your operations.
Trade & Shipping Terms
What is 1:1?
A term used on AliExpress — particularly in fashion, accessories, and electronics categories — to indicate that a product is a replica or close copy of a branded original, made to look identical to the authentic item.
Why it matters: This is a serious compliance and legal risk. Listing or reselling 1:1 replica products on any major marketplace — eBay, Amazon, Walmart, TikTok Shop — violates platform policies and intellectual property laws. Sourcing 1:1 items exposes you to VeRO takedowns, account suspension, and in some jurisdictions, legal liability. Treat any AliExpress listing using this term as a hard avoid.
What is BOGO?
A promotional pricing structure where purchasing one unit entitles the buyer to receive a second unit at no additional cost — or at a significantly reduced price.
Why it matters: BOGO deals on AliExpress are a legitimate sourcing tool when buying samples or testing a new supplier — you receive two units for the cost of one, which allows you to assess product quality more thoroughly without doubling your test spend. As a selling strategy on your own store, BOGO promotions raise UPT and AOV simultaneously.
What is EXW (Ex Works)?
A trade term where the supplier's only obligation is to make the product available at their premises — the buyer is responsible for all transportation, export clearance, shipping, and import costs from the factory door onward.
Why it matters: EXW gives you maximum control over the shipping process but maximum responsibility too. For most AliExpress sellers, EXW terms are encountered when dealing with manufacturers rather than trading companies — and without a freight forwarder to manage the logistics chain, EXW can quickly become complicated and expensive.
What is FOB (Free on Board)?
A shipping term meaning the supplier covers all costs and responsibilities until the goods are loaded onto the departing vessel or aircraft — after which all risk and cost transfers to the buyer.
Why it matters: FOB pricing on AliExpress tells you the product cost stops at the point of departure. Everything from that point — international freight, insurance, import duties, and last-mile delivery — becomes your responsibility. Misunderstanding FOB pricing is one of the most common reasons sellers underestimate their true landed cost per unit.
What is DDP (Delivered Duty Paid)?
A shipping arrangement where the seller pays all costs associated with importing goods into the destination country, including duties, taxes, and customs-related charges — so the customer receives the shipment without paying any additional import fees at delivery.
Why it matters: Since duties and taxes are included upfront, packages move through customs faster with fewer delays, and buyers aren't hit with unexpected charges, which improves satisfaction and reduces abandoned deliveries. For sellers sourcing internationally and shipping to US customers through Walmart, DDP removes friction at the point of delivery and protects your seller metrics from delays caused by customs holds.
Tracking Status Codes
What is AE_CC_IM_EXCEPTION?
A tracking status code that appears when a package has been flagged during customs inspection in the destination country — typically indicating the parcel has been pulled for review by customs authorities and is temporarily held.
Why it matters: Based on verified AliExpress cases, this status most commonly appears after a package arrives in the destination country and is sent for customs scrutiny. It does not automatically mean the parcel is lost or seized — but it does mean the delivery timeline is now outside your control or your supplier's. As a seller, if this status persists beyond a reasonable window, opening a dispute within the Buyer Protection period is your primary recourse.
What is Dispatched to Overseas?
A tracking status confirming the package has cleared the origin country's export customs (typically in China) and is en route to the destination country — handed off from the origin carrier to the international shipping network, awaiting a flight or ship to arrive.
Why it matters: This is the tracking update that tells you the hardest part of the journey has begun. From here, the parcel typically enters a GMTC transit country before arriving at the destination. Delivery times after this status vary widely depending on the shipping method used — from a few days for AE Premium to several weeks for standard options.
What is GMTC?
GMTC stands for Global Mail Transit Country. When a package receives a GMTC update, it means the shipment has entered a transit country during its journey and will be unloaded from its current mode of transport and loaded onto another.
Why it matters: Because the item is only passing through, it will not be subject to customs clearance — similar to a stopover when flying a long-haul flight as a passenger. If an order is stuck on GMTC for an extended period, it is advisable to contact the seller or open a dispute if an unreasonable amount of time passes, especially within the 60-day buyer guarantee period.
What is Origin and Customs?
A tracking status or listing section indicating the country from which the product is being shipped and the applicable customs handling process at the point of export.
Why it matters: Origin information directly affects your customer's import duties, delivery time, and potential customs delays. A product shipping from a local warehouse versus shipping from China has entirely different delivery and cost implications — and misrepresenting or ignoring origin details leads to customer disputes when delivery timelines don't match expectations.
What is Awaiting Delivery?
A tracking status indicating the order has been shipped by the supplier but has not yet been confirmed as delivered by the carrier or the customer.
Why it matters: This status is where most customer anxiety lives. If an order sits in "Awaiting Delivery" for an unusually long time, it may signal a lost parcel, customs hold, or carrier issue. As a seller, monitoring orders stuck at this stage proactively — before the customer contacts you — protects your dispute rate and buyer satisfaction scores.
Store & Inventory Abbreviations
What is MOQ (Minimum Order Quantity)?
The smallest number of units a supplier will accept in a single order — below which they will not fulfil. It refers to the minimum number of products that a user has to request to place an order — however, it is a term that does not usually appear on AliExpress since most AliExpress suppliers accept single-unit orders.
Why it matters: When MOQ does appear, it is typically on wholesale or manufacturer listings. Confirming MOQ before committing to a supplier protects you from being locked into bulk purchases that don't match your current order volume.
What is SKU (Stock Keeping Unit)?
A unique identifier code assigned to each individual product variant in your catalogue, covering size, colour, model, or any other attribute that makes it distinct.
Why it matters: Every platform — Walmart, Amazon, Shopify — runs on SKUs internally. Mismanaged SKUs lead to inventory mismatches, fulfilment errors, and reporting chaos. A clean SKU structure from day one saves enormous operational headaches as your catalogue scales.
What is OEM (Original Equipment Manufacturer)?
A product made by the original manufacturer but sold without branded packaging — often the identical item found in branded retail, minus the label.
Why it matters: OEM products on AliExpress allow sellers to source genuine-quality goods at lower prices and apply their own branding. However, listing OEM products incorrectly — claiming brand-name status they don't have — is a fast path to VeRO complaints and listing removals on platforms like eBay and Amazon.
What is Supplier Processing Time?
The number of days a supplier requires to prepare and dispatch an order after it is placed — completely separate from the shipping transit time shown on the listing.
Why it matters: A listing showing "10-day delivery" may still have a 5-day processing time, meaning the customer waits 15 days before receiving it. Always add processing time to shipping time when calculating the real delivery estimate you communicate to your customers — mismatched expectations are the leading cause of disputes on AliExpress-sourced orders.
What is a Dropshipping Supplier (Vendor/Manufacturer)?
The entity on AliExpress who holds the physical stock, processes the order, and ships directly to your customer. Vendors are typically resellers or trading companies; manufacturers produce the goods themselves.
Why it matters: Buying from a manufacturer rather than a vendor usually means lower unit costs and more flexibility on customisation or packaging. However, manufacturers on AliExpress don't always offer the same responsive communication or fulfilment speed as established trading companies. Understanding which type of supplier you're working with shapes your pricing, lead time expectations, and risk level.
What is Supplier Tier?
AliExpress classifies suppliers using performance badges — Top Rated Supplier, Trade Assurance eligibility, years of operation, and positive feedback scores — to signal reliability levels.
Why it matters: Tier signals are your fastest shortcut to vetting a supplier without placing a test order. A supplier with 4+ years, 95%+ positive feedback, and a Top Rated badge has a track record. A brand-new store with 10 orders and no reviews is a gamble, especially at volume.
What is Supplier Optimization?
A feature within DSers that helps sellers identify the highest-rated supplier for any given product promptly — allowing you to switch to a better supplier without manually updating every listing.
Why it matters: Your current supplier may not always be your best option. A new supplier offering the same product with faster shipping, lower cost, or better quality can improve your margins and customer satisfaction simultaneously. Supplier Optimisation tools surface these alternatives without requiring you to rebuild your product catalogue from scratch.
What is Inventory Sync?
An automated process where your selling platform updates product availability in real time based on what your AliExpress supplier has in stock — preventing you from selling items that are out of stock at the source.
Why it matters: Without inventory sync, you risk accepting customer orders for products your supplier can no longer fulfil — triggering cancellations, refunds, and damage to your seller metrics on every platform you sell on. Tools like DSers provide this function automatically.
What is Drop?
On AliExpress, this term carries two distinct meanings: first, it refers to the act of importing or downloading a product document — often used in dispute processes. Second and more commonly, it refers to the fulfilment model where orders are shipped directly from the supplier to the end customer without the seller holding stock.
Why it matters: In the context of product listings, seeing "Drop" associated with a supplier usually signals they are familiar with and open to direct-to-customer fulfilment — a key indicator when vetting sourcing partners on AliExpress.
What is 1 PCS?
Shorthand for "1 Piece" — indicating the minimum purchasable quantity of a product is a single unit, with no bulk order requirement.
Why it matters: This is one of the most important filters when sourcing on AliExpress for online selling. Products listed as 1 PCS mean you can order individual units per customer order — ideal for the model where you only purchase after a sale is made, with no upfront bulk commitment.
What is Blind Dropshipping?
The practice of requesting the supplier to leave out any AliExpress branding, invoices, or promotional materials from the package so the end-customer does not know the item originated from AliExpress. Best communicated using the checkout order note: "We are dropshipping. Please no invoices, no logos."
Logistics & Shipping Abbreviations
What is AE Standard Shipping?
AliExpress's mid-tier shipping service — more reliable tracking and faster than basic free shipping options, but more affordable than AE Premium. Typical delivery ranges from 15 to 30 days depending on the destination.
Why it matters: AE Standard Shipping has largely replaced ePacket as the default recommended shipping method on AliExpress. It offers fast delivery options from 3 to 12 days for certain routes thanks to agreements AliExpress has made with carriers. It strikes the best balance between cost and reliability for most sellers — fast enough to maintain acceptable customer satisfaction while keeping shipping costs manageable at scale.
What is AE Premium Shipping?
AliExpress's fastest cross-border shipping service, using commercial airline carriers and priority handling to deliver packages significantly faster than standard options — typically 7 to 15 days.
Why it matters: Premium Shipping commands higher shipping costs but delivers faster transit times and more reliable tracking updates. For high-ticket products where customer experience expectations are elevated, AE Premium reduces the window for buyer anxiety, disputes, and negative reviews from slow delivery.
What is ePacket?
A cross-border shipping method originally developed as a partnership between China Post and postal services in 30+ destination countries, designed for small, lightweight packages from Chinese suppliers.
Why it matters: Historically the most popular tracked shipping method for AliExpress sellers due to its balance of affordability and speed — typically 10 to 20 days to major markets. While newer options like AE Standard Shipping have largely replaced it in many routes, ePacket remains a benchmark when evaluating supplier shipping options and is still active on certain country routes.
What is Combined Delivery?
A shipping option where multiple items from the same supplier are consolidated into a single package and shipped together rather than as separate parcels.
Why it matters: Saves on shipping costs per unit and reduces the number of tracking numbers your customer receives. However, combined delivery extends the overall processing time since the supplier waits until all items are ready before dispatching. For time-sensitive orders, clarify with the supplier whether combined delivery is applied automatically or by request.
What is eCommerce Integration?
The connection between AliExpress and your selling platform — Shopify, WooCommerce, eBay, or others — allowing products, orders, and tracking information to sync automatically between your store and your AliExpress supplier.
Why it matters: Without integration, every order requires manual processing — copying addresses, placing orders individually, and updating tracking numbers by hand. Integration eliminates that entirely. Tools like DSers handle this natively, making the entire fulfilment loop nearly automatic at scale.
What is Logistics Score / Shipping Speed?
A supplier rating metric visible in the AliExpress DS Center that measures how reliably and quickly a supplier processes and ships orders — rated out of 5 stars based on real order data.
Why it matters: This is your fastest shortcut to vetting a supplier's fulfilment reliability without placing a test order. A supplier rating above 4.5 out of 5 in shipping speed largely suggests a good supplier. A low logistics score means your customers will wait longer and your reviews will suffer — even though the delay is entirely the supplier's fault.
