“Wi-Fi transmitter” is a broad trade description. A standalone access point, Wi-Fi modem, optical router, mesh node and device integrating 4G/5G may differ in both customs classification and specialised regulatory treatment. The importer must analyse network functions, interfaces, operating bands, transmit power and every integrated radio technology.
Quick conclusion
Vietnamese HS code 8517.62.51 is the first code to consider for wireless local-area network equipment. It should not be selected merely because the packaging says Wi-Fi. If the equipment does not meet that description or has another principal function, 8517.62.59 or another provision may need to be compared.
For import controls in 2026, the HS code, product description and technical specifications must be checked together against Circular 36/2026/TT-BKHCN, effective from 1 July 2026. A matching HS code alone neither proves nor removes the conformity and quality obligations.
Technical file required before classification
- Exact model and manufacturer’s catalogue.
- Functional block diagram identifying modem, router, switch and access-point functions.
- IEEE 802.11 standards and operating frequency bands.
- Conducted power/EIRP and antenna type.
- WAN, LAN and optical ports, SIM slot and cellular capability.
- Bluetooth, Zigbee, RFID or other radio modules.
- Power supply and indoor/outdoor operating environment.
Photographs and the phrase “wireless router” are insufficient. Classification and conformity assessment must be based on the exact model, not a similar unit in the same product family.
HS classification analysis
8517.62.51 — wireless LAN equipment
This code is considered first where the equipment transmits, converts and receives data in a wireless local-area network. The catalogue and block diagram should demonstrate that this is the product’s objective function.
8517.62.59 — other equipment
The residual “other” code should not be used simply because the configuration is unclear. It is considered only after more specific descriptions have been analysed and excluded. For composite equipment, the principal function and the relevant Section and Chapter Notes must be reviewed.
Modules and parts imported separately
A Wi-Fi module, printed circuit assembly, antenna or power supply imported separately may have a different code from the complete access point or router. The condition in which the goods are presented to customs remains decisive.
Recommended customs description
Wireless local-area network access point, IEEE 802.11 …, operating in … GHz bands, EIRP … mW, with/without router, modem or cellular function, model …, manufacturer …, new 100%.
The frequency bands and power stated in customs records must be consistent with the catalogue, label, test report and conformity file. Avoid declarations limited to “Wi-Fi device” or “router”.
Specialised inspection and conformity in 2026
Circular 36/2026/TT-BKHCN lists medium- and high-risk products and goods under the Ministry of Science and Technology’s responsibility. It was issued on 30 June 2026 and took effect on 1 July 2026. For a particular model, the importer should compare three layers:
- the HS code shown in the list;
- the legal product description; and
- the actual technical parameters and applicable national technical regulation.
A shared HS code does not mean every product under it follows the same procedure. Conversely, changing the marketing name does not avoid an obligation when the technical nature still falls within the controlled line.
Radio equipment meeting the exact band, power and operating conditions may qualify for licence-exempt use under Circular 08/2021/TT-BTTTT. Licence-exempt use of spectrum is a separate issue from certification, declaration of conformity, product-quality inspection and other applicable requirements.
Import duty and VAT
Duty should be determined only after the final eight-digit code is supported. The importer must then check the MFN tariff, any special preferential tariff based on origin and C/O, and the VAT rules effective on the declaration date. This article does not quote a universal rate because a difference in function, origin or evidence can change the outcome.
Import dossier
- Contract, invoice, packing list and bill of lading.
- Catalogue, datasheet, label photographs and block diagram.
- Table of frequency bands, power and integrated technologies.
- Product-quality registration, certification and/or declaration of conformity required for the exact product line.
- C/O where preferential tariff treatment is claimed.
- Authorisation and additional technical documents where required.
Practical procedure
Step 1 — Confirm the exact model before ordering. Do not use a test report or datasheet for a nearby model without proof that its scope covers the imported model.
Step 2 — Build a radio-parameter table. Record each band, power level, wireless standard and technical regulation to be checked.
Step 3 — Compare HS candidates. Explain the choice between 8517.62.51, 8517.62.59 and any alternative provision.
Step 4 — Determine the specialised procedure. Check the exact line in Circular 36/2026/TT-BKHCN and the current spectrum rules.
Step 5 — Align all filings. The customs declaration, conformity dossier, catalogue and product label must describe the same model and parameters.
Frequently asked questions
Is every Wi-Fi access point classified in 8517.62.51?
No. It is a relevant code for wireless LAN equipment, but the principal function and exact configuration still need to match the legal description.
Does low transmit power exempt the product from every procedure?
No. A power threshold may affect a particular spectrum or conformity rule, but the full code, description, band, technology and applicable technical regulation must still be checked.
Can a conformity certificate for a similar model be used?
Only where the governing rules and technical evidence show that the certificate or test report legally covers the exact imported model. A series name alone is not sufficient.
