1. Where does it ship from, and where to?
This is the single most predictive fact on the page. "Ships from China, 12–20 days" and "Ships from a US warehouse, 3–5 days" are different products at the same price. A brand with regional warehousing has made a capital commitment to your market; a brand that ships everything from Shenzhen has not, and its returns process will reflect that.
Look for a specific destination list, not a shipping-carrier logo wall. "We ship worldwide" usually means "we ship to some countries and will discover yours at checkout".
2. Who is the merchant of record?
The merchant of record is the company legally responsible for the sale. It may be the brand, or it may be a marketplace or a payment intermediary. If the terms and conditions name a different company from the one on the storefront, understand which of them your consumer rights run against — in practice it is the one that took your money.
3. Is there a returns address in your country?
The strongest single signal of a real operation. A returns address in your own country means the brand can receive a return without a customs event; a returns policy that requires you to post to China means that for a $30 order, the return is economically dead.
Read the returns clause for two things specifically: who pays return freight, and whether the window is measured from delivery or from dispatch. From dispatch is materially worse for you.
4. How does it take payment?
Card networks and PayPal give you a chargeback route. You can raise a dispute, the network adjudicates it, and the money moves. Bank transfer, crypto, and some regional wallets do not offer this — once paid, the money is gone and your only remedy is asking nicely.
A store that offers only bank transfer is not necessarily fraudulent. It is a store where you have given up your main remedy, which is a different and equally relevant fact.
5. Is the electrical product legal where you live?
Anything mains-powered or with a radio needs destination-market approval: CE and UKCA in Europe, FCC in the US, and the right plug type. Two failure modes are common. A 220V-only appliance in a 120V market either will not work or will work dangerously. A radio product approved only for its home market may transmit on bands that are not permitted where you are.
A brand that publishes its certificate numbers is telling you it expects to be held to them.
6. What is the customs position on your order?
Duty and import VAT are usually the buyer's obligation, and they are assessed on the landed value including shipping. Below a de-minimis threshold many countries collect nothing; above it you may get a demand from the carrier before delivery. The thresholds and rates change, so check your own country's current position rather than trusting a figure you read on a blog — including this one.
7. Does the warranty require shipping back to China?
A 24-month warranty that only works by posting the product to Shenzhen is not a warranty you will use. Check whether there is a regional service centre, a local distributor that honours claims, or at minimum a spare-parts channel.
8. Is this the brand, or a reseller?
The same factory output is sold through both, sometimes with the same photographs. The tell is the domain, the About page, and whether the product line is coherent. A store with genuine engineering will tell you about the engineering; a reseller storefront has nothing to say that is not in the supplier's listing.
Neither is automatically bad. But a reseller adds no quality control and cannot help you with a defect, so buy on price and delivery, and expect nothing from support.
9. What is your actual recourse?
Before you pay, answer one question: if nothing arrives, or arrives broken, what do I do? If the answer is "raise a chargeback within the network's window", you have a real remedy and a deadline. If the answer is "email them and hope", decide whether the price difference is worth that.
This guide is general in nature. It describes how cross-border direct-to-consumer commerce usually works, not the terms of any specific store. Duty thresholds, certification regimes and chargeback windows change; verify the current position for your own country before relying on any figure here.
