Radio rules come first
Bluetooth is a radio technology, so Bluetooth audio products fall under radio rules in most markets. Those rules govern which frequencies and powers are allowed, and what testing and marking are required. The rules differ by market, and a product compliant in one market is not automatically compliant in another. The inquiry should name the destination market and ask which radio approvals the product holds for that market.
Safety and marking
Safety rules cover batteries, chargers and electrical safety. Marking rules cover what must be printed on the product and the packaging. Both vary by market, and both are checked at customs and by retailers. A buyer who discovers a marking problem after shipment has already paid for the problem.
What to ask, and what this guide does not do
Ask the supplier, by market, which approvals and certificates apply, and ask for the documents before payment. Name the market in the inquiry: a general question gets a general answer.
This guide states no certificate names and no approval claims, because none are evidenced for this supplier. Certificates are available upon request, and the documents, not this guide, are the evidence.
Common mistakes buyers make
The first mistake is assuming approval in one market means approval in another. Radio rules, safety rules and marking rules differ by market, and a product compliant in one market can be stopped in another.
The second mistake is discovering a marking problem after shipment. Marking is checked at customs and by retailers, and a problem found there has already been paid for. Marking questions belong in the inquiry, before the order.
Questions to put in the inquiry
Name the destination market, and ask which radio approvals, safety approvals and markings apply to that market. Ask for the documents, by name, before payment. A general question gets a general answer, and a general answer does not clear customs.
Ask what changes if the market changes: a product bound for two markets may need two sets of approvals, and the inquiry should say so.
How to check a supplier's answers
Check each approval against the market named. An approval for a different market, or for a different product, is not an approval for this order. Ask for the document, not the claim.
Check markings against the destination's rules: what must be printed on the product, and what must be printed on the packaging. A marking that satisfies one market may fail another.
What the paperwork should show
The paperwork should show, per market, the approvals held, the certificates with their documents, and the markings applied. Anything missing from the paperwork is missing from the deal.
This guide states no certificate names and no approval claims, because none are evidenced for this supplier. The documents, not this guide, are the evidence.
A buyer's walk-through
Imagine a buyer shipping Bluetooth audio products to two markets for the first time. The buyer names both markets in the inquiry, asks for the approvals and markings for each, and receives documents for one market and a general assurance for the other. The buyer treats the assurance as unanswered, asks again for the document, and holds the second market's shipment until it arrives.
That buyer ships late to one market and on time to the other. The late shipment is a delay; the alternative was a stopped shipment, which is worse.
Edge cases buyers forget
A buyer who ships to a market through a third country faces the rules of both the transit country and the destination, and sometimes the rules of the country where the goods are warehoused. A single-market inquiry misses the transit rules entirely.
A buyer who re-exports goods bought in one market to another faces the same problem in reverse: the approvals that cleared the first market do not clear the second. Re-export is a new export, with new rules.
How this connects to the product lines
Radio rules apply to every Bluetooth product on this site: earphones and speakers alike. Safety rules apply to batteries and chargers in both lines. Marking rules apply to the product and the packaging in both lines.
Timers and thermo-hygrometers on this site are not radio products, so their compliance questions differ: safety and marking, but not radio approvals. A buyer who applies the Bluetooth checklist to a timer will ask the wrong questions.
Timing: when to ask, and when to stop asking
Ask compliance questions in the first inquiry, naming the destination market. Compliance answers that arrive after shipment are useless, because the shipment has already been made and the problem has already been paid for.
Stop asking when every market named has a document attached to its approval. More questions after that point delay the shipment without improving it.
Questions buyers forget to ask
Buyers forget to ask about battery transport rules, which are separate from product approvals and can stop a shipment on their own. They forget to ask about packaging markings for batteries, which differ from product markings.
Buyers also forget to ask what happens if a market changes its rules between order and delivery. The answer belongs in the paperwork, not in a dispute.
Battery transport rules, separately
Battery transport rules are separate from product approvals, and they can stop a shipment on their own. Lithium batteries travel under transport rules that govern packing, labelling, quantity per package, and documentation, and those rules apply whether the battery is shipped alone or inside a product.
A buyer should ask, per shipment, which transport rules apply and what documents the shipment needs. A product approval does not cover transport, and a transport document does not cover product approval. Both are needed.
When rules change between order and delivery
Markets change their rules, sometimes between an order and its delivery. A buyer should ask, before payment, what happens if the rules change: who pays for retesting, who pays for remarking, and whether the shipment can be held until the new rules are met.
Those answers belong in the paperwork. A rule change discovered at customs is a stopped shipment; a rule change planned for in the paperwork is a delay with a known cost.
A note on documentation language
Documents should be in the language the destination's authorities accept, and translations should be done by someone who understands the technical terms. A mistranslated approval can be worse than a missing one, because it looks complete while saying the wrong thing.
Ask the supplier which languages the documents are available in, and whether translations are certified where the destination requires it. A document in the wrong language is a document that cannot be checked, and an unchecked document does not clear customs.
