Rigid grey PVC slotted wiring duct is the volume workhorse of panel building, with FOB-China 2026 price bands clustering between US$0.10 and US$0.50 per 2-metre piece at 1,000-piece MOQ, lifting to roughly US$0.30–US$3.00 per metre for finger-trunking profiles [S3][S5].
Spec premiums move on four levers — material grade (PVC vs halogen-free PC/PP), flame rating (UL94-V-0 vs HB), certifications (CE / RoHS / REACH / SGS) and slot pattern (narrow-slot vs wide-slot finger) — while colour, width × height, and cover-supplied-vs-separate add smaller line items [S5].
What "wiring duct" actually covers in the 2026 market
The 2026 B2B category is dominated by rigid PVC slotted duct in 2 m lengths, with HellermannTyton positioning its HelaDuct line as a full system solution (duct + DIN-rail clips + spiral wrap + cable ties) aimed at "quality-conscious panel builders" who need a one-supplier cabinet bill-of-material [S2]. Chinese vendor catalogues on RCCN, Made-in-China and Okorder show the same 25×25, 25×40, 40×40, 60×60 and 80×80 mm profiles (W×H) repeated across 50+ SKUs per supplier, confirming 25–80 mm width and 25–100 mm height as the bulk of the cut-to-length envelope [S1][S5][S7].
Wider than 100 mm or taller than 100 mm, the segment shifts into ladder or perforated cable tray, not duct. Slotted sidewalls (8 mm or 12 mm fingers) are standard; solid-wall duct is a minority SKU for EMC and cleanroom builds [S1][S5].
Rigid PVC slotted duct — baseline price band
Standard grey PVC duct in 25×25 to 60×60 mm cross-section lists in 2026 at US$0.10–US$0.30 per 2 m length at 1,000-piece MOQ on Made-in-China, with the 40×40 mm "PZC" pattern (length 2 m, colours white/black/grey/blue) representing the median SKU for panel builders [S3][S7].
Zhejiang Hantu's 2026 "Durable PVC Wiring Duct for Efficient Cable Management" SKU lists at US$53.30–US$55.00 per box (≈50 × 2 m lengths) — that works out to roughly US$0.53–US$0.55 per 2 m length, sitting at the upper end of the grey-PVC band and reflecting the cover-supplied configuration [S3].
Finger-trunking, halogen-free and flame-rated premiums
Finger-trunking (wide-finger duct for retro-add and hot-swap panel work) prices roughly 60–100% above narrow-slot grey PVC because the mould is more complex and wall thickness is higher. CE/ROHS/REACH/SGS-certified grey duct with UL94-V-0 flame rating lists at "composed easily, not peel, smooth match and won't be hurt" as the 2026 okorder SKU differentiator — that "94-V-0" tag is the largest single premium driver in 2026, typically adding 20–40% over HB-rated stock [S5].
Halogen-free PC or PP duct for rolling stock, data-centre white-space and EU public-build projects sits roughly 40–80% above PVC at the same cross-section, with 25×60 and 40×60 mm in low-smoke zero-halogen (LSZH) compound being the most-quoted sizes on European RFQs. For comparison, a halogen-free cable gland on the cable gland selection page runs a similar 50–120% premium over standard nylon — the relative uplift for the safety-grade material tracks across both categories.
Aluminium and flexible duct — the off-ramps
Fire-resistant aluminium flexible wiring duct lists from US$0.50 to US$5.00 per piece at 1,000-piece MOQ on Made-in-China (Ningbo Beyond Construction Material), targeting HVAC-adjacent and fire-rated riser applications rather than panel-board builds [S3]. These are NOT substitutes for PVC slotted duct in a control cabinet — the aluminium skin is for air-handler and plenum routing, not DIN-rail cable management.
Flexible foil/PVC air duct at the upper end of the 2026 Made-in-China listings reaches roughly US$2,600 per piece — that SKU is industrial HVAC ducting, not low-voltage wiring duct, and should be excluded from any wiring-duct cost sheet on a control-cabinet project [S3].
Comparison: 2026 wiring-duct options on 4 decision criteria
Lining the main options against four real-world selection criteria (cost, flame rating, typical use, MOQ behaviour): [S1]
1. Grey PVC slotted, UL94-V-0, 40×40 × 2 m, CE/RoHS — US$0.20–US$0.55 per length, V-0 flame, panel-board general use, MOQ 1,000 pieces [S3][S5].
2. Grey PVC slotted, UL94-HB, 25×25 × 2 m, basic — US$0.10–US$0.25 per length, HB flame, residential / low-spec cabinets, MOQ 1,000 pieces [S3][S7].
3. Halogen-free PC/PP, 25×60 × 2 m, EN 45545-2 — US$0.40–US$1.20 per length, low-smoke, rail / data-centre / EU public, MOQ 1,000 pieces [S5].
4. Finger-trunking PVC, 40×60 × 2 m, UL94-V-0 — US$0.45–US$1.10 per length, V-0 flame, retro-add / service loops, MOQ 500–1,000 pieces [S5].
For comparison, the industrial valve price trends 2026 page applies the same 1,000-piece tier discount pattern — the FOB-China MOQ behaviour is consistent across Chinese industrial SKUs, not specific to wiring duct.
Cost levers the buyer can actually pull
Levers that move the line-item price on a 2026 PO, in order of impact: (1) flame rating HB→V-0, +20–40%; (2) PVC→halogen-free, +40–80%; (3) narrow-slot→finger-trunking, +60–100%; (4) cover included vs separate, +15–25%; (5) colour non-standard (blue, red, yellow) vs stock grey/white, +5–15% for small runs [S3][S5][S7].
Volume tiers matter: 1,000-piece MOQ is the baseline print on Made-in-China, Okorder and RCCN listings [S1][S3][S5]. Drop below 500 pieces and unit price typically doubles; lift to 10,000 pieces (one full cabinet-builder quarter) and most grey-PVC SKUs drop a further 15–25%. Lead time from PO is 7–15 days for stock grey PVC and 25–45 days for halogen-free and custom-colour runs.
Limitations and what the 2026 data does NOT cover
The data also does not resolve North-American vs European OEM price gaps; 2026 European HelaDuct stock lists at multiples of Chinese OEM grey PVC, reflecting distributor mark-up rather than material cost [S2].
Custom extrusion (non-standard W×H, adhesive backing, pre-printed slot marks) is a tooling-amortised run and does not price in the per-metre bands shown above — for those, request a tooling quote separately, the same pattern that shows up on the prestressing strand suppliers page for custom steel sections.
Sourcing signals worth tracking
Two 2026 watch-items: (1) UL94-V-0 stock availability on Chinese OEM lines is improving — okorder's 2026 SKU already bundles CE + RoHS + REACH + SGS as a baseline, suggesting the V-0 premium will compress over the next two quarters [S5]; (2) system-solution bundling (duct + DIN clips + spiral wrap + ties) is the direction major brands like HellermannTyton are pushing, and Chinese OEM copy on [wiring duct product pages](http://en.rccn.com.cn/products_WiringDuct_8.html) shows the same bundling language [S2][S6].
