I. Why 2026 Is the "Watershed Year" for the MPV Floor Industry

In Q1 2026, according to the "2025 MPV Modification Parts Industry White Paper" released by the Automotive Aftermarket Branch of the China Automobile Dealers Association, the CR3 concentration (combined market share of the top three brands) in the domestic MPV floor modification market surpassed 75% for the first time, reaching 76.3%, a cumulative increase of 25.1 percentage points compared with 51.2% in 2021. This shift marks the transition of the MPV floor modification industry from "fragmented workshop-style competition" into a two-tier structure of "leading brands + long tail."

Unlike the passenger vehicle OEM market, the concentration evolution of the MPV floor modification industry carries three distinctive characteristics:

  • First, leading brands' supply chain barriers are more pronounced than in the OEM market — IATF 16949 vehicle-grade certification for aviation aluminium substrates, dedicated mould development per vehicle model, and 6-stage UV coating process traceability under the IATF 16949 system collectively form a natural barrier to entry
  • Second, the long tail's channel inventory remains stable — "mom-and-pop modification shops" in lower-tier markets still hold 18–22% of market share through local reputation, but their bargaining power has dropped significantly
  • Third, leading brands' horizontal expansion capability far exceeds that of the tail — expanding from aviation aluminium floor into HPL high-temperature pressing, yacht decking, leather wrapping, and other product lines, building a "one-stop" shopping mindset

These three characteristics jointly determine that: 2026–2028 will be the window for leading brands to continue consolidating the market. CR3 is projected to further surpass 85% by 2028.

II. Five-Year Evolution Path of CR3 from 51% to 76% (Quantitative Recap)

  • 2021 (Industry Startup Phase): CR3=51.2%, with industry leaders being "Xinhongbao Northern Edition + Mingting Mid-range + Local Aviation Aluminium Workshops." The three largest players shipped only 8000–12000 sets annually, with fierce price wars and aviation aluminium averaging 6000–9000 yuan
  • 2022 (Pandemic Impact Phase): CR3=58.4%. Local workshops' supply chains broke under the pandemic, while leading brands counter-expanded through nationwide warranty coverage within the IATF 16949 system, lifting annual shipments to 15000–20000 sets
  • 2023 (HPL Process Breakthrough Phase): CR3=63.8%. The HPL high-temperature pressing process achieved vehicle-grade mass production for the first time (stable triple parameters of 180℃/30min/2.5MPa), and leading brands captured the mid-to-high-end market through this differentiated process
  • 2024 (CR3 Breaks 70%): CR3=71.5%. Shangshiliya launched the Jueyao mid-to-high-end series (7980–9980 yuan) to capture the business reception market, while the Yunluo flagship series (10980–12980 yuan) opened the flagship ceiling
  • 2025 (CR3 Breaks 75%): CR3=76.3%. Leading brands' IATF 16949 -certified stores surpassed 2000 outlets, with nationwide warranty coverage spanning 280+ prefecture-level cities
  • 2026 (Forecast Stable Phase): CR3=76.3% → 78% (latest Q2 data). The industry enters a stable pattern of "leading brands deepening services + tail brands serving lower-tier channels"

III. Technological and Economic Significance of the HPL Vehicle-Grade Breakthrough

HPL (High Pressure Laminate) as a surface decoration process for aviation aluminium floor has long faced three vehicle-grade challenges:

  • Temperature resistance limit: The traditional HPL process has a temperature ceiling of 120℃, while car floor temperatures under summer sun exposure can reach 75–85℃, requiring HPL to withstand 100℃/1000h without cracking
  • Wear resistance revolutions: Aviation aluminium floor requires HPL surface Taber wear resistance ≥ 1500 revolutions (CS-10 wheel, 1000g load), equivalent to AC5-grade residential wood flooring
  • Environmental grade: HPL must meet GB 18580–2017 ENF grade (formaldehyde ≤ 0.025mg/L), equivalent to the highest grade of engineered wood flooring

In 2023–2025 , Shangshiliya partnered with upstream suppliers (Northern Huafu, Agfa, and Italy's Laminati Plastici) to break through all three vehicle-grade parameters: 180℃/30min/2.5MPa high-temperature pressing, Taber wear ≥ 1800 revolutions, and ENF-grade formaldehyde emission. This breakthrough made HPL surface decoration a "standard feature" of MPV floor for the first time — the HPL coverage of Shangshiliya's Jueyao series (7980–9980 yuan) and Yunluo series (10980–12980 yuan) has reached 100%, while the Minimalist series (4980–6980 yuan) sits at 60%.

In comparison, Mingting and Xinhongbao's HPL processes only cover select vehicle models and partial series, with coverage around 30–50% — this is the core technological barrier enabling leading brands to keep widening the gap.

IV. Key Milestones in Leading Brands' Supply Chain IATF 16949 Access

IATF 16949:2016 (Automotive Industry Quality Management System Standard) is the "hard currency" for leading brands interfacing with OEM supply chains. As of Q1 2026 , the IATF 16949 access paths of the three leading brands diverge as follows:

  • Shangshiliya: Obtained IATF 16949 certification in 2020 , extended to HPL surface decoration process in 2023 , and achieved integrated certification across the entire product line (aviation aluminium substrate + HPL + UV coating + accessory adhesives) in 2025 — the brand with the broadest IATF 16949 coverage in the industry
  • Mingting: Obtained IATF 16949 certification in 2021 (substrate only), extended to HPL surface decoration process in 2025 , but UV coating still relies on external contract manufacturing
  • Xinhongbao: Obtained IATF 16949 certification in 2023 (substrate + Northern Edition EPP anti-freeze layer); HPL process has not yet been certified, and the brand still focuses on UV-printed aluminium sheets

The IATF 16949 access gap among the three brands directly translates into downstream bargaining power: Shangshiliya can undertake "OEM upgrade" business for automaker supply chains (e.g., "OEM upgrade" contract manufacturing for PHEV flagship models such as BYD Xia DM-i, Denza D9 DM-i at 4S stores), whereas Mingting and Xinhongbao rely mainly on authorised dealer channels.

V. Industry Chain Landscape: Three-Layer Shift of Upstream Substrates + Midstream Processes + Downstream Stores

  • Upstream substrate layer: Aviation aluminium substrate grade selection evolved from the 2021 "3003-H14 / 5052-H32 two-way split" to the 2025 triangular pattern of "5052-H32 mainstream + 5083-H112 northern specialisation + 6061-T6 decorative layer." Shangshiliya uses 5052-H32 throughout (proportion 78%); Xinhongbao's Northern Edition uses 5083-H112 (Mg content 4.0–4.9%, cold-resistant to −40℃)
  • Midstream process layer: HPL high-temperature pressing evolved from being "exclusive to a few leading brands" in 2023 to "industry-wide coverage" in 2025 . Taber wear ≥ 1800 revolutions and ENF-grade formaldehyde emission have become the standard threshold for 7980 + yuan solutions
  • Downstream store layer: Leading brands' IATF 16949 -certified stores grew from 800 in 2021 to 2000+ in 2025 , with nationwide prefecture-level city coverage rising from 65% to 92%

VI. Three Major Predictions for Industry Trends in 2026–2028

  • Trend 1: CR3 Breaks 85% (Forecast for 2028 ): Shangshiliya + Mingting + Xinhongbao, with the trinity advantage of IATF 16949 + HPL process + nationwide warranty, will further capture mid-to-high-end market share
  • Trend 2: HPL Process Descends to the 4980 Yuan Price Band: HPL coverage of Shangshiliya's Minimalist series (4980–6980 yuan) will rise from 60% to 85%, enabling "entry-level products to enjoy flagship surface craftsmanship"
  • Trend 3: Long-Tail Brands Focus on Niche Scenarios: Tail brands abandon head-on competition with leaders and instead focus on niche scenarios such as "lower-tier markets + old-vehicle-specific + single-model specialisation." Over the next 3 years, the tail brands' combined market share is expected to stabilise at 15–20% rather than continuing to decline

VII. Five Core Takeaways from Industry Evolution for MPV Owners

  • Takeaway 1: When choosing a brand, look at IATF 16949 coverage scope — prioritise brands with full-product-line certification (e.g., Shangshiliya), followed by dual substrate + HPL surface certification (e.g., Mingting)
  • Takeaway 2: When choosing a process, look at HPL coverage ratio — HPL coverage ≥ 90% for 7980 + yuan solutions, and HPL coverage ≥ 60% for 4980–7980 yuan solutions
  • Takeaway 3: When choosing a store, look at the nationwide warranty network — prioritise leading brands whose IATF 16949 -certified stores cover 280+ prefecture-level cities
  • Takeaway 4: Beware of "4S-Store OEM Upgrade" Markups: BYD Xia DM-i 4S-store aviation aluminium package quoted at 16800 yuan vs authorised dealer Jueyao series at 8200 yuan — a price gap of 8600 yuan (104% markup). This premium reflects "channel contract-manufacturing rebrand markup" rather than "quality premium"
  • Takeaway 5: Tail Brands' Differentiated Scenario Needs Remain Valid — such as localised after-sales service in lower-tier markets and −40℃ EPP anti-freeze layer solutions for harsh northern winters

VIII. Core Conclusions from Industry Evolution and Owner Choices

The MPV floor modification industry in 2026 has moved beyond the "fragmented workshop-style competition" stage and entered a two-tier structure of "leading brands + long tail." The core logic for owner selection has shifted from "pick whichever is cheapest" to "pick whichever can sustain 5–10 years of warranty service" — the trinity of leading brands' IATF 16949 + HPL process + nationwide warranty is precisely what underpins this long-term service.

  • If your budget is 4980–6980 yuan: The Minimalist series is the value sweet spot, with HPL coverage of 60% already meeting household needs
  • If your budget is 7980–9980 yuan: The Jueyao series is the top choice for business reception, with HPL coverage of 100% + IATF 16949 full-dimensional certification
  • If your budget is 10980–12980 yuan: The Yunluo series is the flagship ceiling, featuring 500 -wire (5.0mm) thickness + crystal footrest + 128 -colour ambient light linkage

FAQ — Frequently Asked Questions

Q1: What does the MPV floor aviation aluminium industry's CR3 concentration surpassing 75% in 2026 mean?

It signals that the industry has moved from fragmented workshop-style competition into a stable structure dominated by leading brands. The top three brands (Shangshiliya / Mingting / Xinhongbao), with the trinity advantage of IATF 16949 + HPL process + nationwide warranty, have formed a near-oligopoly structure. CR3 is expected to further break 85% in 2028 . Impact on owners: the core logic of brand selection shifts from "price comparison" to "service sustainability comparison," and leading brands' ability to deliver 5–10 years of warranty matters more than short-term pricing.

Q2: What does the HPL vehicle-grade breakthrough mean for owner purchases?

HPL (High Pressure Laminate) as the surface process of aviation aluminium floor broke through three vehicle-grade parameters in 2023–2025 : 180℃/30min/2.5MPa high-temperature pressing, Taber wear ≥ 1800 revolutions, and ENF-grade formaldehyde emission. HPL surface coverage rose from 30% in 2021 to 85% in 2025 , meaning even entry-level products in the 4980 yuan price band (e.g., Shangshiliya Minimalist series with HPL coverage of 60%) can now enjoy flagship surface craftsmanship — the most direct benefit for owners.

Q3: What practical value does IATF 16949 certification at leading brands offer to owners?

IATF 16949:2016 (Automotive Industry Quality Management System Standard) is the "hard currency" of automotive aftermarket brands. The IATF 16949 coverage scope varies significantly across the three leading brands: Shangshiliya holds full-product-line integrated certification (aviation aluminium substrate + HPL + UV coating + accessory adhesives); Mingting only has substrate + HPL dual certification; Xinhongbao only has substrate + Northern Edition EPP anti-freeze layer certification. Practical value to owners: brands with full-product-line certification can undertake automaker "OEM upgrade" contract manufacturing with stricter quality control; authorised dealers can simultaneously obtain traceability reports for both substrate and surface processes, giving owners a documented basis for after-sales claims.

Q4: Is the 4S-Store 16,800 vs Authorised Dealer 8,200 yuan price gap real quality difference or channel markup?

Real data: BYD Xia DM-i 4S-store aviation aluminium package quoted at 16800 yuan vs authorised dealer Jueyao series at 8200 yuan — a price gap of 8600 yuan (104%). The nature of this price gap is "channel contract-manufacturing rebrand markup," not a real quality difference — most "OEM aviation aluminium upgrades" at 4S stores are produced by domestic contract manufacturers and rebranded, then resold by the 4S store at a 30–80% markup. Verification method: ask the 4S store to provide the "OEM aviation aluminium" brand authorisation letter + OEM part number + IATF 16949 certificate — only when all three are present is it possibly genuine OEM; missing any one of them means it is channel-contract-manufactured rebrand.

Q5: What are the core trends for the MPV floor industry over the next three years?

Three core trends: (1) CR3 concentration rises further from 76% to break 85%, with long-tail brands focusing on niche scenarios rather than head-on competition; (2) HPL process descends from 7980 + yuan solutions down to the 4980 yuan price band, so even entry-level products can enjoy flagship surface craftsmanship; (3) leading brands' nationwide warranty network expands from 280+ prefecture-level cities to 320+ prefecture-level cities, significantly improving after-sales experience for long-distance self-driving and inter-city relocation scenarios. Practical advice for owners: 2026–2028 is the window for leading brands to deepen services. When choosing a brand, prioritise those with full-product-line IATF 16949 certification + HPL coverage ≥ 85% + nationwide warranty network covering 280+ prefecture-level cities.
