When you source industrial precision gear sets from Korea for the German market, the compliance documentation your supplier provides determines whether the shipment clears customs on time. An accurate origin declaration on the commercial invoice can reduce import duty to zero under the EU-Korea Free Trade Agreement, but that only works when the supplier's other paperwork — quality certificates, a material test document, and a chemical compliance statement — is also complete. This checklist covers eight documents to request, how to verify each one, and what to look for before goods leave the Korean factory.
Why a Pre-Shipment Compliance Checklist Protects the German Importer
Importing industrial machinery components from outside the EU places customs clearance responsibility on the German importer. A missing or mismatched document can hold a shipment at the German border, delay production schedules, and generate unexpected broker fees. The good news: most of the compliance work falls on the Korean exporter — the documents are well-defined and consistent across shipments. Your role as the buyer is to know which documents to ask for, how to confirm they are current, and when to push back before goods are loaded onto the vessel.
Korean precision gear sets enter Germany under HS subheading 8483.40, which covers gears and gearing, ball or roller screws, and gear boxes and speed changers. No product-specific German import licence applies to this category. The compliance task is one of assembling proof: preferential tariff origin, quality and material certification, and chemical-substance compliance for the alloy and any surface treatment applied.
Eight Documents to Request from Your Korean Gear Supplier
Before confirming a purchase order, ask your Korean supplier to confirm that every item below can be provided with the shipment. Resolving gaps before an order is placed saves far more time than chasing documents after goods are already at the port.
Pre-order document request list for Korean precision gear sourcing
- ✓ HS 8483.40 classification confirmationVerify the gear is classified correctly on the invoice before the first shipment
- ✓ Commercial invoice with EU-Korea FTA origin declarationOrigin declaration must be on the invoice; approved-exporter number required for orders above EUR 6,000
- ✓ Packing listItem descriptions must match the invoice and the physical goods exactly
- ✓ Transport documentBill of lading or air waybill issued by the carrier
- ✓ EN 10204 Type 3.1 material certificateOne per production batch, reporting SCM440 alloy-steel chemistry and measured test results
- ✓ Current quality certificate (ISO 9001 or IATF 16949:2016)Confirm the certificate names IATF 16949:2016, not the cancelled ISO/TS 16949; check expiry date
- ✓ REACH SVHC compliance declarationSupplier statement on Candidate List substances in the alloy, any plating, and any surface coating
- ✓ Declaration of incorporation (if partly completed machinery)Required plus assembly instructions if the supplier classifies the assembly under Regulation (EU) 2023/1230
The EU-Korea FTA Origin Declaration: How It Reduces Your Import Duty
The EU and South Korea have maintained a free trade agreement since its provisional application began in July 2011 and formal ratification was completed on 13 December 2015. According to the European Commission's Access2Markets database, all customs duties on industrial goods traded between the EU and South Korea were eliminated by 1 July 2016. An industrial precision gear set that qualifies as originating under the agreement enters Germany at a 0% preferential duty rate rather than the standard third-country rate.
The mechanism is an origin declaration written directly on the commercial invoice — there is no separate certificate form. For orders at or below EUR 6,000, any Korean exporter may add the declaration text. When the shipment value exceeds EUR 6,000, the exporter must hold an approved-exporter authorisation number from Korean customs, and that number must appear in the declaration. An origin declaration covers shipments dispatched within 12 months of its issue date, and the Korean exporter must retain all records proving originating status for at least five years. Before accepting a supplier invoice on a large order, verify that the approved-exporter number is present — without it, the zero-duty preference is unavailable for that consignment.
How to verify the EU-Korea FTA origin declaration on your supplier's invoice
- 1
Check HS 8483.40 appears on the invoice
The product description and HS subheading must match the goods being shipped and the supporting documents.
- 2
Locate the origin declaration text
The statement must be written directly on the commercial invoice — there is no separate origin certificate form under the EU-Korea FTA.
- 3
Verify the approved-exporter number for orders above EUR 6,000
For consignments exceeding EUR 6,000, the declaration must include the supplier's approved-exporter authorisation number from Korean customs.
- 4
Note the declaration date
The declaration is valid for 12 months from the date of issue. Do not use it for shipments dispatched after that window expires.
- 5
Retain the invoice and file for audit
Keep the invoice as your proof of preferential duty claim. The Korean exporter is required to retain originating-status records for at least five years.
IATF 16949 vs ISO/TS 16949: Reading Your Supplier's Quality Certificate
German OEM and Tier-1 customers typically require a recognised quality-management certificate before approving a new precision-component supplier. ISO 9001 is the accepted baseline. For automotive gear applications, the standard buyers expect is IATF 16949, not the older ISO/TS 16949 designation that a number of Korean factories still reference in their documentation — and that distinction is worth catching before your procurement team signs off on a supplier.
The International Organization for Standardization cancelled ISO/TS 16949 when IATF 16949:2016 was published in October 2016. Third-party audit certification to the old standard was no longer available after 1 October 2017. IATF 16949:2016 operates as a supplement to ISO 9001:2015, so a valid IATF 16949 certificate implies ISO 9001 compliance, but the reverse is not true. When reviewing a supplier's quality paperwork, look for the exact text "IATF 16949:2016" and a current expiry date. Any document naming "TS 16949" or "ISO/TS 16949" references a cancelled standard and should not be accepted as evidence of current certification.
How to spot an outdated quality certificate on a supplier's documentation
"ISO/TS 16949" or "TS 16949" on a certificate means it is expired
According to ISO, ISO/TS 16949 was cancelled and replaced by IATF 16949:2016, and third-party certification audits to the old standard were no longer permitted after 1 October 2017. Any certificate that names ISO/TS 16949 as the governing standard is therefore expired and should not be accepted as evidence of current quality-system certification. Ask your Korean supplier for the current IATF 16949:2016 certificate showing a valid scope and expiry date — a certified supplier should be able to provide this without delay.
EN 10204 Type 3.1 Material Certificate: Steel Traceability for SCM440 Gears
Industrial precision gears manufactured from SCM440 chromium-molybdenum alloy steel are carburised and heat-treated to a surface hardness of HRC 58–62. That hardness profile depends entirely on the alloy reaching the correct chemistry before heat treatment begins. For European buyers, the document that confirms this chain of traceability is an EN 10204 Type 3.1 inspection certificate — and it is worth specifying this standard explicitly in your purchase terms rather than accepting whichever test document the supplier provides by default.
Under BS EN 10204:2004, a Type 3.1 document is prepared by an inspection representative who is independent of the manufacturing department, and it reports the actual measured test results for the specific batch of material delivered. This ties the steel heat number to the finished gear in the shipment. A simpler Type 2.2 manufacturer's test report does not carry independent validation and does not meet the traceability standard most European quality audits require. Request a Type 3.1 certificate for each production batch, not once per order, so traceability holds if the order spans multiple manufacturing runs.
CE Marking and Partly Completed Machinery: What Documentation to Request
A precision gear set does not receive a CE marking as a standalone product. Because a gear has no independent function, it cannot be certified as complete machinery. Under Regulation (EU) 2023/1230 — which takes effect from 20 January 2027 and supersedes Machinery Directive 2006/42/EC — the applicable category for a gear assembly built for incorporation into another machine is "partly completed machinery." According to EU-OSHA, this covers assemblies that cannot perform a specific application on their own and are designed for integration into larger machinery.
The classification has direct consequences for the document pack your supplier must prepare. A bare gear component requires the standard customs documents together with the material and quality certificates described above. If the Korean supplier classifies the gear assembly as partly completed machinery under the new Regulation, a declaration of incorporation and assembly instructions must also accompany the shipment. Confirm the classification in writing with your supplier before raising the purchase order — disagreements at the border about which documents should travel with the goods are costly and slow to resolve.
How gear classification determines the documents your supplier must provide
| Gear as a plain component | Gear as partly completed machinery | |
|---|---|---|
| CE marking on the gear | No — a gear cannot function independently as machinery | No — partly completed machinery is not CE-marked as machinery |
| Governing regulation | EU customs, EU-Korea FTA origin rules, REACH/RoHS where applicable | Regulation (EU) 2023/1230 essential health and safety requirements (from 20 January 2027) |
| Extra documents required | None beyond the standard customs and quality-certificate pack | Declaration of incorporation plus assembly instructions |
| How to confirm which applies | Agree classification in writing with the Korean supplier before raising the purchase order | Agree classification in writing with the Korean supplier before raising the purchase order |
REACH and RoHS: Chemical Compliance Questions to Raise Before Shipment
A metal gear is treated as an "article" under EU REACH, which means the primary obligation concerns Substances of Very High Concern rather than registration of the substance itself. According to the European Chemicals Agency (ECHA), when an article contains a Candidate List SVHC at a concentration above 0.1% by weight, the supplier must communicate that information to any downstream user upon request. Where the total SVHC quantity in articles supplied to one EU recipient exceeds one tonne per year, an ECHA notification is also required. The Candidate List covers more than 250 substances, so ask your supplier to confirm SVHC status for the steel alloy, any plating layer, and any protective coating applied to the gear surface.
RoHS Directive 2011/65/EU restricts lead, cadmium, mercury, hexavalent chromium, and related substances, but it applies only where the gear is incorporated into electrical or electronic equipment. A gear used in a purely mechanical drive application typically falls outside RoHS scope. Because the answer depends on the end product, obtain a written supplier declaration before the shipment is made — it takes little time to prepare and removes the ambiguity entirely for German customs and your own quality audit trail.
Frequently Asked Questions
Does my Korean supplier need approved-exporter status for every shipment to Germany?
Only when the consignment value exceeds EUR 6,000. Per the European Commission's rules of origin, any Korean exporter can issue the EU-Korea FTA origin declaration on the invoice for shipments at or below that threshold. Above EUR 6,000, the supplier must hold and quote an approved-exporter authorisation number from Korean customs. Confirm this status with your supplier at the outset, particularly for initial trial orders that may be near the threshold.
Is ISO/TS 16949 still a valid quality certification for an automotive gear supplier?
No. According to ISO, ISO/TS 16949 was cancelled and replaced by IATF 16949:2016, and third-party audit certification to the old standard was no longer available after 1 October 2017. A certificate naming ISO/TS 16949 references a cancelled standard. For automotive gear applications, ask for a valid IATF 16949:2016 certificate showing a current scope and expiry date.
What distinguishes an EN 10204 Type 3.1 certificate from a standard test report?
An EN 10204 Type 3.1 document requires an inspection representative independent of the manufacturing process to validate the reported test results for the exact material supplied in that batch. A Type 2.2 manufacturer's test report carries no independent verification. For alloy-steel precision components, specify Type 3.1 explicitly in your purchase order conditions rather than leaving the format to the supplier's discretion.
When does Regulation (EU) 2023/1230 replace the current Machinery Directive?
According to EU-OSHA, Regulation (EU) 2023/1230 applies from 20 January 2027 and replaces Machinery Directive 2006/42/EC on that date. If partly completed machinery declarations in your current supply chain reference the 2006 Directive, ask your Korean supplier to confirm that updated documentation under the new Regulation will be available before the transition date.
