The 10 warning signs to check before you commit to a new overseas manufacturer, from a refusal to video call through to demands for full payment upfront. A practical red flags checklist for Australian importers.
Last updated: 30 September 2026
In short: The biggest red flags in an overseas manufacturer are a refusal to let you visit or video call the factory, no business licence or paperwork on request, prices far below every other quote, and pressure to pay the full amount upfront. If a supplier shows two or more of these signs, get a second opinion before you send a deposit. This checklist covers the 10 warning signs Epic Sourcing's team watches for when we screen a new factory in China or Vietnam.
A bad supplier can cost you months and thousands of dollars. Once a deposit lands in the wrong account, it is gone. Many Australian importers only learn what a proper factory looks like after they have already been burned once. This guide skips the theory and gives you the exact signs our sourcing team looks for during supplier screening, so you can catch a problem before you commit.
Work through this list before you place a deposit with any new factory in China or Vietnam. One flag on its own is not always fatal. Two or more should stop you.
A working factory has nothing to hide. If a supplier keeps finding reasons to delay a visit or a live video walkthrough, that is the clearest warning sign on this list. Many "manufacturers" listed on sourcing platforms are trading companies that have never seen the inside of the factory floor they claim to run.
Every factory in China must register a business licence, and most exporters hold a customs registration too. Ask for a copy early. A supplier who stalls or sends a blurry, unreadable scan is telling you something.
If one quote comes in 30% or more under every other quote you have received for the same product and specification, find out why before you get excited. It usually means a cut corner: thinner materials, no proper quality checks, or a factory planning to swap components after your deposit clears.
Standard terms in China and Vietnam sourcing are a 30% deposit with the balance due before shipping, often against a bill of lading. A supplier who insists on the full amount before production starts is removing your only leverage if something goes wrong.
Stock photography, images copied from a competitor's catalogue, and renders dressed up as product shots are common on sourcing platforms. Ask for photos and video of your specific product, not a catalogue shot, and compare them closely against the sample that arrives.
Not sure if your supplier checks out?
Epic Sourcing's bilingual team verifies factories in China and Vietnam in person, before you send a deposit.
Book a Free Consultation ↗A factory that knows its own production line answers specific questions directly: capacity, lead time, materials, and certifications. Constant vague answers, long delays, or a habit of changing the subject when you ask about quality control is a sign you are dealing with a middleman who does not know the product well.
Ask how they check goods before they ship. A supplier with a proper QC process can describe it in a sentence or two. One who resists an independent inspection company checking the goods before you pay the balance is telling you they expect problems.
Cross-check the company name, address, and registration number across their website, sourcing platform profile, and any invoices they send. Mismatched details, a residential address for a factory of hundreds of workers, or a company name that changes between documents are all worth chasing up.
A factory that has been exporting for years should have a trail: platform reviews, trade assurance history, or past clients you can call. Be careful with an account that is only a few months old but somehow claims a decade of manufacturing experience.
Australian importers have specific rules to meet: DAFF biosecurity requirements, Australian Consumer Law, and category-specific standards such as the PFAS restrictions now in force for textiles and cookware. A supplier who has never heard of these, or waves the question away, is leaving the compliance risk sitting entirely on you at the border.
One flag is a reason to ask more questions, not necessarily to walk away. Two or more, especially numbers 1, 2 and 4 together, is a strong reason to keep looking. Before you send a deposit to any new factory, get an independent supplier verification check, ask for a video walkthrough of the production line, and put payment terms in writing.
This is exactly what Epic Sourcing's Supplier Finding service is built for. Our bilingual team in China and Vietnam handles the factory visit, the paperwork check, and the reference calls before you ever wire a deposit.
Once you have a supplier that clears this checklist, our companion guide on Local vs Overseas Manufacturers ↗ walks through how to weigh up a local factory against a verified one in China or Vietnam.
Watch for the flags in this guide: no factory visit or video call, a missing business licence, prices far below every other quote, and demands for full payment upfront. Two or more of these together is a strong warning sign.
No. The standard and safer approach is a 30% deposit with the balance paid before shipping, ideally against a bill of lading. A supplier who insists on 100% upfront is removing your leverage if something goes wrong.
A trading company buys from factories and resells to overseas buyers, sometimes marking up the price without adding any quality checks of its own. Some list themselves as manufacturers on sourcing platforms even though they have never run a production line.
Yes, though the documents are usually in Chinese and can be faked convincingly. A sourcing agent or verification service can confirm the registration against government records and check it matches the address and bank details the supplier gave you.
A sourcing agent with people on the ground can visit the factory in person, check paperwork against local records, and speak the language during negotiations, catching problems an overseas buyer would otherwise only find out about after the goods ship.
