A “network adapter” may be a wired NIC, USB‑Ethernet converter, Wi‑Fi/Bluetooth dongle, cellular modem, optical module or passive connector. Relying only on the trade name can cause the wrong HS code, missed QCVNs, incomplete EIRP evidence, model mismatches and customs delay. This guide provides an end-to-end control map from PO review through post-clearance.

* Subject to the actual model, active function, interface, origin and rules effective on the customs declaration date.

Operational conclusion: “Network adapter” is not one legal category. A wired NIC, USB‑Ethernet dongle, Wi‑Fi/Bluetooth card, 4G/5G modem, SFP transceiver, media converter and passive coupler require separate classification and policy analysis.

SCOPE

This guide covers active network adapters connected internally or externally to computers, servers, industrial controllers, POS terminals and other automatic data-processing equipment.

Wired Ethernet NICs: PCIe/PCI/M.2 and USB‑A/USB‑C/Thunderbolt to RJ45.
Wireless adapters: USB/PCIe/M.2 Wi‑Fi, Bluetooth dongles and combined Wi‑Fi + Bluetooth cards.
Items requiring separate treatment: 4G/5G modems, routers, access points, CPE, media converters, SFP modules, gateways, VPN/security appliances, RF modules and ICs.
Used/refurbished, samples, warranty replacements, project cargo and EPE/FDI imports may follow different controls.

Review the actual catalogue, datasheet, model and import purpose. Do not apply a wired-adapter conclusion to a wireless model or treat a non-operational part as a complete device.

HS CODE, TAXES AND C/O

Heading 8517.62 is commonly reviewed because it covers machines for receiving, converting and transmitting or regenerating data. For an active wired adapter designed solely for connection to automatic data-processing machines, 8517.62.43 is a key reference, but the commercial word “adapter” is never sufficient by itself.

Reference HS	When it may apply	Reference tax position	Main risk	Required evidence
8517.62.43	Controllers/adapters, gateways, bridges, routers and similar devices designed solely for connection to ADP machines; commonly reviewed for active NICs and USB‑Ethernet adapters	MFN 0%; ordinary duty often reviewed at 5%; budget VAT 10%	Routing, modem or standalone functions may change classification	Catalogue, block diagram, host/network interface, chipset
8517.62.51	Wireless LAN equipment when the actual product description and function match	MFN reference 0%; budget VAT 10%	HS alone does not determine sector policy	RF report, Wi‑Fi mode, bands, EIRP and antenna
8517.62.59	Other combined data transmit/receive equipment	MFN reference 0%	“Other” used without a classification rationale	Functional diagram and protocol list
8517.79.99 or an appropriate parts code	Only for a non-independent part/module meeting parts classification rules	Check the final code	Complete device declared as a part	BOM, pinout, firmware and independence analysis
8544/8536 or another heading	Passive cable, coupler or connector without active data-processing circuitry	Depends on final code	Every connector called a network adapter	Construction and BOM
Separate cellular/router/security code	4G/5G modem, CPE, router, media converter or security appliance	Check final code	Incorrect telecom, crypto or quality policy	Manual, SIM/IMEI, routing and security functions

VAT planning: use 10% as a prudent budget for heading 8517. Apply 8% only after confirming the final HS and that the item is not excluded from the VAT-reduction scope effective on the declaration date.

A C/O may not reduce duty further where MFN is already 0%, but it can remain relevant for origin evidence, projects, tenders, customer requirements or a different final HS.

SECTOR-SPECIFIC POLICY MATRIX

Product situation	Potential policy	Evidence	Handling authority/portal	Recommended timing	Risk note
Wired Ethernet NIC with no radio	Usually outside the radio entries of Circular 36/2026; still review HS, labels and used-goods status	Catalogue, block diagram, chipset and label	Customs; market surveillance for circulation	Before final invoice	Confirm no hidden or optional radio module
2.4 GHz Wi‑Fi adapter	Review Circular 36/2026, QCVN 54:2020/BTTTT and QCVN 112:2017/BTTTT against the product description, HS and EIRP; the list refers to 60–200 mW for the relevant equipment	RF report, EIRP, antenna gain, client/AP mode and model mapping	National public-service portal/inspection body and designated conformity bodies when applicable	Before ETA	Do not assume a client adapter is automatically exempt
5 GHz Wi‑Fi adapter	Review QCVN 65:2021/BTTTT and QCVN 112:2017/BTTTT; the relevant list uses EIRP from 60 mW	Reports for each operating sub-band and region firmware	Same as above	Before booking/ETA	Market version and firmware may change bands/power

Integration module/part	Review independent operation, parts HS and obligations of the finished product	BOM, pinout, firmware and integration manual	Customs and sector authority	Design/BOM stage	“Module” does not automatically mean no QCVN
Military/dual-use specification	Review strategic-trade control only where the technical/end-use criteria match	End-use, end-user and performance data	Competent licensing authority	Before contract	Not a blanket rule for ordinary commercial adapters

KEY LEGAL INTERPRETATION

HS is not the only trigger

Circular 36/2026 links HS codes to product descriptions and management requirements. Matching an HS alone is not enough.

Prove the 60 mW threshold

Use reliable evidence of maximum EIRP, including antenna gain and software modes.

Multiple radios mean multiple QCVNs

All applicable QCVNs must be satisfied, while duplicate testing of the same requirement should be avoided.

Hardware and firmware mapping matters

Region code, chipset, antenna or firmware changes can invalidate a report or certificate.

LABELLING AND POST-CLEARANCE

Imported network adapters should carry original labels and, before market circulation where applicable, Vietnamese supplementary labels showing the product name, model/part number, responsible entity in Vietnam, origin and necessary identifying specifications. Do not obscure serial numbers, MAC addresses, model information or conformity marks.

Retain the customs, valuation, C/O, HS memo, RF reports, certificates, inspection results, labels and model mappings by shipment. Reassess compliance when the manufacturer changes the chipset, antenna, hardware revision or firmware affecting bands or power.

FREQUENTLY ASKED QUESTIONS

Does a network adapter require an import licence?

There is no universal answer. A wired Ethernet adapter usually does not trigger radio controls, while Wi‑Fi/Bluetooth/cellular or dedicated crypto/security products may require conformity, quality inspection or a licence.

Can 8517.62.43 be used for every network adapter?

No. It is a key reference for adapters designed solely for connection to ADP machines. WLAN equipment, modems, routers, modules, SFPs and passive connectors may fall elsewhere.

Is a Wi‑Fi adapter below 60 mW fully exempt?

Do not describe it as a full exemption. Circular 36/2026 excludes certain below-60 mW equipment from the referenced short-range-radio entry, but evidence and other HS/QCVN/labelling obligations must still be reviewed.

What about an ordinary Bluetooth dongle?

Check the maximum EIRP and actual configuration. Bluetooth/Zigbee below 60 mW is noted in the relevant exclusion, but additional radios or functions can change the result.

Does a combined Wi‑Fi + Bluetooth card need both interfaces reviewed?

Yes. All applicable QCVNs must be addressed; duplicate testing may be optimised, but an interface cannot simply be ignored.

Is a 4G/5G USB modem just a network adapter?

Commercially it may be called one, but it is normally a cellular data terminal/modem requiring separate band, IMEI, RF/SAR and QCVN review.

What are the import duty and VAT?

Many 8517.62 lines have a reference MFN rate of 0%; ordinary duty is often budgeted at 5%. Use 10% VAT prudently and apply 8% only after confirming the effective reduction conditions.

Is C/O necessary where MFN is 0%?

Not necessarily for duty reduction, but it may remain relevant for origin evidence, projects, tenders or a different final HS.

Are samples and warranty replacements automatically exempt?

No. The mechanism may differ, but HS, model, condition, radio functions and the legal basis for any exemption must still be documented.

Can refurbished network adapters be imported?

High risk. Review the prohibited used-IT list and any exception mechanism before purchase and shipment.

What if the report model suffix differs from the invoice?

Obtain formal manufacturer mapping covering hardware, chipset, module, antenna, firmware and certification scope.

Is an SFP transceiver a network adapter?

Do not conclude from the name. Review its optical function, host dependency and whether it is a complete device or a part.

TGIMEX SOLUTION

This guide maps HS, taxes, C/O, documentation and sector controls for network adapters. For an actual shipment, TGIMEX reviews the precise catalogue, datasheet, model, chipset, interfaces, RF report, EIRP, documents, origin and import purpose.

Pre-ETA legal review

Wired/Wi‑Fi/BT/cellular/module split, HS, Circular 36, QCVN, VAT, C/O, labels and condition.

Compliance document control

Invoice, PL, B/L/AWB, catalogue, RF reports, certificates, labels and model mapping.

E2E coordination

International transport, sector procedures, customs, delivery and post-clearance records.

For wireless, cellular or security-sensitive models, do not wait until arrival. A small mismatch in model, chipset, antenna, firmware or EIRP can cause additional testing, clearance delay and unplanned storage costs.
