Which compliance file does my destination market actually need?
Name the market before asking for documents, because the same certificate does not answer all three. For the EU the file is CE with LVD 2014/35/EU, EMC 2014/30/EU and RoHS 2011/65/EU plus the GPSR (EU) 2023/988 obligations; UKCA is prepared on request for the UK; for the US the material declaration is the FDA 21 CFR 177.2600 silicone statement. Ask to verify each certificate number with the issuing body, and read the scope rather than the cover page. The market compliance matrix maps document to destination.
Why do documents stop shipments more often than the product does?
Import compliance is a documentation discipline before it is a testing one. A shipment is rarely held because somebody tested the product and found a failure; it is held because a declaration is missing, names the wrong directive, or cannot be produced on request. That is good news: the documents import compliance asks for are the cheapest part of the puzzle to get right, and assembling them is entirely a matter of asking before you ship rather than after.
The full set we issue is listed in the certificates we issue and analysed market by market in the five-market comparison. This guide is about how those requirements work rather than what to tick.
Which certification marks does each market actually require?
Before the classification and the declaration, there is a simpler question: which conformity marks a destination expects to see on the product and in the file. They are not the same set everywhere, and screening a supplier on the wrong one wastes the questions that matter. The marks below are the ones a B2B buyer should ask for by name, market by market.
The same five destinations are compared as a table in the market compliance matrix, and the documents each one expects to travel with the goods are listed in the certificate pack. The distinction that catches first shipments is that a mark and a test are different things: FCC is a declaration tied to the radio, REACH is a substance statement against a live candidate list, and PSE sits on the battery — each lives in a different part of the file.
None of these marks is a medical approval, and none of them is presented as one. Where that boundary sits — what the product is claimed to do, who it is for, and where the buyer's own market claims begin — is stated in the product disclaimer, which is the same wording we give a notified body and an importer. Reading it before a listing is drafted is cheaper than rewriting the listing after a platform review.
How does the customs classification code set your duty rate?
No tariff schedule has a heading written for this product. A device is classified by what it does and what it is made of, and for an object with a motor, a battery, a silicone skin and a marketing story, two or three headings can genuinely be defended. That is not a loophole someone left open; it is the ordinary condition of a category that no one wrote a heading for, and it has one practical consequence: the code is a commercial decision, not a clerical one, and the decision belongs to the importer of record.
- 8543.70 — electrical machines and apparatus having individual functions
- For: the product is powered, carries a motor and a control circuit, and its function is not described by a more specific heading. Against: the function has to be electrical, so a passive silicone article does not qualify — one code cannot cover a range that mixes powered and unpowered models.
- 9503 — other toys
- For: the heading covers articles designed for amusement, and its text says nothing about the age of the user. Against: authorities in several markets resist reading adult products as toys, and a challenge you lose is expensive and does not travel — a ruling in one market binds nobody in the next.
- 9019.10 — massage apparatus
- For: reads naturally for a device sold on relaxation, recovery or pelvic-floor training. Against: the claim has to hold across packaging, listing, manual and website; a device marketed as adult novelty contradicts the heading, and the contradiction is what an auditor finds.
- 3926 / 4016 — other articles of plastics, or of rubber
- For: for an unpowered article, material is the only function there is. Against: ignores a motor completely, so it describes a subset of a range rather than the range.
- 8517 — apparatus for the transmission or reception of data
- For: an app-controlled model contains a radio and talks to a phone. Against: reads one component as the whole product — the radio is ancillary to the function, and classified on the radio alone the heading usually overstates what the device is.
The first six digits are international — the Harmonized System maintained by the World Customs Organization — and everything after them is national. That single fact explains the thing buyers find most alarming: the same device can carry a different code in the EU, the UK and the US without anyone having made a mistake. The six digits agree, the national splits diverge, and the rate lives in the national part. A quotation that offers "the HS code" without saying which schedule it was read from has not supplied a rate at all — it has supplied the first half of one [World Customs Organization, 2022].
What we can do is narrow the decision. Every published specification states material by component — where the silicone ends and the ABS begins, what the motor and the cell are, whether there is a radio — because those are the facts a classification turns on, and a broker cannot classify a device described only as a massager. What we do not do is assign the code for you. The code is declared by the importer of record, and a factory that offers to fix it is transferring a liability it cannot carry; if your broker needs a component breakdown for a specific SKU, ask for it with the sample, because it is a document we issue rather than a conversation we have. The classification is the start of import compliance, not the whole of it: the same device then needs a declaration that names the heading, labelling that matches the market, and an economic operator who can be reached.
In the EU, what file has to sit behind the CE mark?
CE marking for products in this category is generally self-declared. That surprises buyers who think of CE as a certificate issued by somebody; in practice the manufacturer declares conformity and holds a technical file. The consequence is important: the mark itself proves little, and the file behind it proves everything.
- Directives that apply. Low Voltage 2014/35/EU for powered products, EMC 2014/30/EU for electronic emissions, and RoHS 2011/65/EU for restricted substances. All are freely readable on EUR-Lex.
- General product safety. Regulation (EU) 2023/988 replaced the older product safety directive and raises expectations on traceability and risk assessment.
- Chemicals. REACH Annex XVII restricts phthalates and other substances; evidence is a third-party report against the current candidate list.
- What to hold. Declaration of conformity, technical file, RoHS report, REACH statement and risk documentation.
The General Product Safety Regulation (EU) 2023/988 restates the duty in a form that reaches distance sales and marketplace listings, not only goods on a shelf, and it expects the technical file to exist before the product is offered rather than on request afterwards [European Parliament and Council, 2023]. That expectation — a file that already exists when the listing goes live — is the practical core of EU import compliance for this category.
Two dates are worth carrying in your head. The regulation has applied since 13 December 2024, so any listing placed on the EU market after that date is inside it — including a listing an Amazon or Kaufland seller creates for stock that arrived earlier. And the file it expects is not a folder of certificates: it needs the risk assessment for the actual use, the traceability that lets an authority identify which batch is which, and a named economic operator established in the EU who can be handed a request and answer it. That last point is the one that most often blocks a small first shipment, because a factory in Dongguan cannot be that operator and a marketplace will ask who is.
If nobody in your business can be the EU responsible person, the workable structures are an importer of record who already is one, or an authorised-representative service. Both are cheap next to a customs hold; neither is included in a FOB quotation, and a supplier who says the question is already handled is worth asking for the name.
In Great Britain, does EU paperwork carry over automatically?
Great Britain runs its own conformity marking, UKCA, and maintains its own chemicals regime under UK REACH, which is substantively similar to the EU's but has diverged and will continue to. In practice the two most common errors are assuming EU documentation transfers unchanged, and assuming it never does — the position is specific to the product and worth confirming with the current guidance rather than inferring.
UKCA documentation for our range is prepared on request at no additional charge. It is not included by default because most shipments are EU or US bound, and preparing it for everyone would slow the documents everyone actually needs.
One distinction is worth settling before you plan a UK launch: Great Britain and Northern Ireland are not in the same regime. Northern Ireland continues to apply EU product rules under the Windsor Framework, so a product bound for Belfast needs the EU route, while the same product bound for Glasgow needs the GB one. A distributor with a single UK warehouse rarely thanks you for discovering this at the port, and labelling differs between the two — so ask which of the two the order is actually for, in writing, before artwork is approved.
The other GB-specific habit worth forming is checking the current guidance rather than inferring from the EU position. UK REACH has diverged from EU REACH and will diverge further as the two candidate lists move apart; a substance report written against the EU list is evidence of a different thing from one written against the UK list, and the gap widens quietly rather than all at once. A supplier who can tell you which list your report was written against is doing the work; one who says "REACH compliant" has told you nothing you can use.
Is there a US product approval, or only a material standard?
The US has no federal product approval scheme for this category, and this causes the most confusion of the three markets. What exists is a material provision — FDA 21 CFR 177.2600 — covering rubber articles intended for repeated use, adopted by the industry as the reasonable material benchmark because no standard is written specifically for these products. Claiming FDA approval for the finished device would be false, and is a claim we do not make.
| Market | Accepted as evidence | Not sufficient alone |
|---|---|---|
| European Union | Third-party test reports plus a technical file behind the declaration | The CE mark |
| United Kingdom | UK-referenced declarations and UK-referenced substance reports | An EU declaration with UK destination |
| United States | Material compliance statement and MSDS per skin-contact component | A claim of FDA approval |
FCC deserves one clarifying note. It applies to devices that intentionally emit radio frequency energy. Because the range is app-free with onboard control only, there is no radio module and no FCC claim — which occasionally reads as an omission but is accuracy.
The gap federal rules leave is filled at state level, and California is the one to plan for. Proposition 65 requires a clear and reasonable warning before exposure to a listed chemical, and the list is long enough that a silicone or vinyl article has to be assessed rather than assumed clean. A warning label is not an admission of harm and it is lawful to ship with one; the expensive mistake is printing packaging that omits it and having a retailer refuse the pallet, because the cost of reprinting cartons at that point dwarfs the cost of the warning.
For US import compliance, that means a short, written list rather than a certificate: which components touch skin, what each is made of, whether any listed substance is present above the applicable threshold, and what the label therefore says. We supply the component breakdown and the material statements; the warning decision belongs to the party whose brand is on the carton, because it is that party a state attorney general would address.
Is there an international standard written for this product category?
Yes, and it is newer than most buyers assume. ISO 3533:2021 — "Sex toys: design and safety requirements for products in direct contact with genitalia, the anus, or both" — is the first international standard written for these products rather than borrowed from another industry. According to the Wikipedia entry ISO 3533, the work started as a Swedish standards proposal after hospital data showed a rise in injuries from retained products, was carried forward through ANSI, and was published by ISO in September 2021. The published document runs to 16 pages and sits under ICS 97.170, body care equipment (ISO 3533:2021); it entered systematic review in July 2026, which is the five-yearly check every ISO standard receives, not a sign that it is being withdrawn.
What it actually asks of a manufacturer is narrower and more useful than the certificate language suggests. It requires a documented risk analysis across the product life cycle, design provisions against retention and against sharp edges or burrs, mechanical safety for moving and removable parts, attention to vibration and to any electrical stimulation, a materials and biocompatibility assessment with cleaning instructions, and user information that states the intended use. It also gives guidance for compiling a restricted substance list, which is the part that connects to RoHS and REACH rather than replacing them.
What it is not matters just as much. There is no ISO 3533 mark, no certificate issued against it, and no accreditation body that approves a product under it — conformity is declared by the manufacturer through the technical file, exactly as with the EU declaration. The scope statement also excludes products classified as medical devices, cosmetics or lubricants, so a claim that a device is "ISO 3533 certified" is overstating what the document is. A supplier who can show where the design file addresses each clause is doing something more useful than one who shows a logo.
In practice the standard is a checklist for the design review a buyer never gets to attend, which is why it is worth naming in a specification: ask which clauses the design file addresses, and ask for the risk analysis rather than the conclusion. The documents that travel with a shipment are listed in the certification pack, and the market-by-market picture — where a standard stops and a mark begins — is in the market compliance matrix, which is the import compliance question a buyer has to answer before freight is booked rather than after the pallet ships.
What does a landed cost contain, line by line?
Duty is one line in a stack, and in most markets it is no longer the largest one. The layers are worth separating because they answer to different levers, and buyers who model a single percentage against the factory price are modelling the smallest part of the problem and none of the fixed part.
That fixed tail is why a first order feels expensive and a reorder feels cheap even when the unit price has not moved. Brokerage, bond minimums, entry filing and inland delivery are charged per shipment or per entry, so their per-unit weight falls as the order grows. It is also why splitting a first order into two small shipments to "test the water" usually costs more than one shipment of the same total quantity — the tail is paid twice.
The base of every value-based layer is the customs value, and the customs value is not automatically the number on your invoice. It is the price actually paid or payable for the goods, adjusted for things the schedule says belong in it — assists, certain royalties, the cost of packing.
Because every percentage in the stack is applied to that one figure, an error at the base compounds through the whole stack rather than staying in a single line. This is a broker question, and it is worth asking before the first entry rather than after a review — the customs-value basis is where import compliance and the landed-cost model meet, so the same conversation serves both.
What has to be on the checklist before you book freight?
- Destination market named on the order, because documentation follows it.
- Declaration references the directives or provisions actually applicable.
- Substance reports in date against the current restricted-substance list.
- Labelling requirements checked, including bilingual requirements where applicable.
- Battery documents — UN38.3 and sector-specific equivalents — requested for the freight mode.
- Certificate of origin, invoice and packing list consistent with each other.
Import compliance before a first shipment is mostly a checklist discipline, and if a line on it cannot be met by a catalogue configuration the remedy is usually a manufacturing change rather than a paperwork fix: a different material, finish or cable. Which changes are cheap and which reset tooling is discussed in OEM vs ODM vs private label — and our own technology and compliance page states exactly what each published figure rests on.
According to the Wikipedia entry Incoterms, the eleven trade terms divide cost, risk and paperwork between seller and buyer at named points, which is why a landed cost is only comparable when the term is printed beside it. The organising logic behind the whole file — that a border asks for a document before it asks about a product — is the same one [Christopher, 2016] describes when he counts customs clearance as a lead-time component rather than an administrative afterthought.

Questions on this guide
When does customs clearance actually start?
Before the goods move. Customs clearance starts with the commercial invoice, the HS heading and the declaration being consistent with each other, all of which are decided at booking. A shipment that arrives with a heading that does not match its description is not cleared late; it was never cleared early.
Do I need my own importer record?
Requirements vary by market and are your obligation as importer, not the factory's. Establish who is importer of record before quoting freight, because it determines whose name goes on several of the documents.
Who is the importer of record, and can it be someone other than me?
It can be, and that choice is a cost decision as much as a legal one. The importer of record is the party that answers to the destination authority for the goods — it carries the conformity obligations, it is named on the labelling, and its details are what a customs officer checks first. A distributor can act as importer of record so the paperwork obligations sit with them; if you act as your own, you take on the technical file and the market surveillance exposure as well as the margin.
How current do the reports need to be?
Old enough is a risk. Restricted-substance lists are updated and test methods are revised, so ask for reports against the current version rather than accepting whatever is on file.
Is CE accepted in the United Kingdom?
Not on its own. UKCA is the marking that applies to the UK market, and a shipment going into both the EU and the UK carries both document stacks. Read them as two destinations even when the goods travel on one vessel.
Do I need FCC certification?
Only if the device has a radio in it. FCC covers intentional and unintentional radiators, so a Bluetooth or app-controlled model needs it and a button-controlled one does not. Claiming it for a product that has no radio is a false claim on a document.
Which document takes the longest to obtain?
Usually the least technical one: the importer name and the labelling artwork. Both are decided after the product is finished, which is why they are the rows missing when a shipment is inspected. The destination-by-destination table lists them per market.
Can one document set cover five markets?
Not in practice. The test reports overlap, but the marking, the labelling language and the named economic operator are per destination. Build the stack per market rather than looking for a single certificate that covers all of them.
Which HS code applies to a rechargeable vibrator?
There is no heading written for the product, so more than one can be defended: an electrical-apparatus heading for the powered function, a toys heading if the argument rests on purpose, a massage-apparatus heading if the product is genuinely sold as one. The first six digits are international and the rest are national, so the code can legitimately differ between the EU, the UK and the US. The decision is declared by the importer of record, not by the factory — and a written ruling is the only way to make it stop being a judgement call.
Will you put an HS code on the commercial invoice for me?
We state what the product is made of and how it works, component by component, and we issue that as a document you can hand to a broker. We do not assign the heading, because the code is a declaration made by the importer of record and a factory that fixes it is taking on a liability it cannot carry across a border. Ask for the component breakdown with your sample and your broker can work from it.
What do buyers most often leave out of a landed cost?
The fixed tail: brokerage, bond minimums, entry filing and inland delivery, which are charged per shipment or per entry rather than per unit. That is why a first order of 200 pieces carries a worse unit cost than the same product at 800, independently of any volume discount — and why splitting a first order into two small shipments usually costs more than one shipment of the same total.
Still open: which documents customs asks for first — or compare the three destination markets.
The border asks for documents, not for confidence, and the document set differs by destination. The compliance matrix is the table to check before freight is booked; the certificate pack is what actually travels with the goods. Where each test is run, and on what instrument, is on the technology page — the part a customs broker will ask you to evidence rather than assert. The document questions that arrive after a shipment is booked rather than before are answered in the compliance questions, including what to do when a certificate names a model you did not order.
