Safety Sensor Supplier for Vietnam — Light Curtains, Laser Scanners & Safety Relays, Factory-Direct from China

The Vietnam safety-sensor market is distributor-dominated: buyers reach the incumbent brands — Autonics, then Omron, SICK, Panasonic and Schmersal — through local resellers, not through China factories directly. That channel adds an importer-plus-distributor-plus-reseller margin on top of the brand price. DAIDISIKE competes on a different axis: factory-direct price, a 1-set MOQ, fast OEM/ODM, and honest CE / IEC 61496 / ISO 13849 documentation to settle the counterfeit anxiety (chính hãng) that dominates VN search. This guide is built around the exact procurement questions Vietnamese buyers ask — MOQ, lead time, FOB, HS code, duty/VAT, payment, certs.

What does DAIDISIKE supply for the Vietnam market?

A complete safety circuit from one China factory — light curtains, laser scanners, relays, door locks and proximity sensors — on a single MOQ and lead time. Most VN buyers come for one product and discover they can spec the whole cell from the same supplier. The two highest-value verticals in Vietnam are power-press / stamping (máy đột dập) hand protection and AGV/AMR mobile-robot safety. Here is the line-up mapped to real DAIDISIKE models.

Why buy factory-direct from China instead of a Vietnam reseller?

Because the safety architecture is identical to the incumbent brands while the channel margin, MOQ and lead time are not. A Type 4 curtain's behaviour is fixed by IEC 61496-1/-2 and ISO 13849-1: dual-channel OSSD, self-checking optics, a defined detection capability and a response time fast enough for the ISO 13855 safety distance. An Autonics SFLA, an Omron F3SG, a SICK C4000 and a DAIDISIKE DQC all answer to that same standard. What differs in Vietnam is the route to buy: the brands arrive through a stack of importer → distributor → reseller. Buying direct from the factory collapses that stack — you talk to the people who make the sensor, order a single set to validate, and repeat at volume on a 3–15 day factory cadence.

DAIDISIKE has built safety sensors since 2013 from a ~3,000 m² factory and exports to 20+ countries including Vietnam and wider Southeast Asia, so “direct” here does not mean unproven — the OEM/ODM, the certs, the export paperwork and the after-sales all come from one source. We do not run a Vietnam office or warehouse: this is a China factory-direct relationship, which is precisely what makes the pricing and the customization possible.

MOQ, lead time, Incoterms and payment for shipping to Vietnam

MOQ 1 set; 3–15 day factory lead; FOB Shenzhen/Guangzhou default; 30% deposit / 70% before shipment by T/T. These are the five numbers Vietnamese procurement asks for first, so here they are in one place. FOB is the standard term for China→Vietnam because it lets you keep your own forwarder and control the short ocean leg into Cat Lai or Hai Phong; CIF, EXW and DDP are available on request. If you pay by L/C, the Incoterm must match the L/C documents.

The “typical VN reseller pattern” column is the general market shape buyers describe, not a quote attributed to any named distributor — confirm your actual terms with each vendor.

HS code, import duty and VAT for safety sensors entering Vietnam

Safety light curtains and laser scanners usually classify under HS 9031 (8536 in some cases); duty + VAT apply on the CIF value, and an ASEAN–China FTA Form E can reduce duty. This is the homework that decides landed cost, so do it before you commit. The two HS lines that come up are 9031 (measuring/checking optical instruments and appliances — often 90318090 / 90319000 in the Vietnam tariff) and 8536 (electrical apparatus for protecting circuits, when the device is presented that way). Safety laser scanners also sit in 9031. Which line your goods take depends on how your customs broker characterises the device.

On top of the duty, Vietnam levies VAT on imported industrial goods, calculated on CIF value plus duty. Because goods of Chinese origin can qualify for preferential duty under the ASEAN–China FTA, a Form E / Certificate of Origin can lower the duty line where the order is eligible — we can issue it. Rates and FTA eligibility change and depend on your exact classification, so confirm the current duty and VAT for your HS line with your Vietnam customs broker. We provide the commercial invoice, packing list, CE Declaration of Conformity and origin documents to support whatever code your broker files.

Are the products genuine and certified? (Hàng chính hãng & CE)

Yes — these are genuine factory-made DAIDISIKE products, built to IEC 61496 and ISO 13849-1, with a CE Declaration of Conformity available for your customs file. Counterfeit anxiety is high in Vietnam, and chính hãng (genuine/authentic) is the single most repeated trust word in VN search, so let us be precise about what is published. The light curtains are built to IEC 61496-1/-2 and ISO 13849-1; the Type 4 / PL e families (DQC, DQT4) are designed to the Type 4 architecture. The safety laser scanners follow the IEC 61496-3 architecture with CE self-declared — we do not claim a Type 3 third-party certification on the scanners. CE is self-declared, ISO 9001 governs the factory quality system, and TÜV testing is available per order when a project requires third-party documentation. We can provide the CE Declaration of Conformity and a test report for customs, and we state only what we have published — no blanket TÜV or UL listing is claimed.

Which brands does DAIDISIKE commonly replace in Vietnam?

On safety architecture they are peers; the gap is commercial — MOQ, lead time, channel margin and customization. Vietnamese buyers benchmark against the brands they already reach through resellers (Bao An / baa.vn, MISUMI VN, ANS, and others). The table below reads those incumbents from their public material only — no copied datasheet, no invented spec — and shows where a factory-direct DAIDISIKE build fits.

Chinese peers already advertise China-direct pricing (ESPE, DADISICK, CYNDAR, Fuwei, KELI), so the factory-direct frame is proven in this market — DAIDISIKE's differentiator inside that field is the combined 1-set MOQ, 3–15 day lead and in-house OEM/ODM.

Two highest-value Vietnam verticals: power press & AGV

DQC / DQA / DQT4 Type 4 curtains for stamping presses (máy đột dập); DLD safety laser scanners for AGV / AMR fleets. For point-of-operation hand and finger guarding on a power press, size the mounting distance with ISO 13855 against the curtain's response time, and tie the OSSD outputs into a DA31 safety relay (PL e / SIL 3) for the stop circuit. For mobile-robot safety — a very active topic among Vietnamese integrators — the DLD05A3 (5 m), DLD20A5 (20 m), DLD30T-5N (40 m perimeter) and SDLD-05A TOF (14 m) provide the warning-field / safety-field zoning that AGV and AMR platforms need. Round out the cell with rơ le an toàn (DA31) and công tắc / khóa an toàn (DX-R1 / DX-W2 / DXL-B) from the same factory and lead time.
