FENG SHANG PRECISION CO., LTD. is a Taiwan-based manufacturer established in 2009 and the company behind Shokunin, the professional brand whose COOLWAVE water-circulation cooling vest — frequently specified as a dual cooling water cooling vest — is supplied into industrial heat-stress applications. This reference collects the supplier capability data that sits behind that product and explains how a Security & Protection buyer should read each data point when assessing production reliability and sourcing risk.

Shokunin is the professional brand launched by FENG SHANG PRECISION CO., LTD., the manufacturer behind the COOLWAVE water-circulation cooling vest.

Why Supplier Capability Decides the Order, Not the Specification

During awareness and research, a cooling vest is a product question: how long the cooling lasts, how heavy the unit is, how it layers over workwear. At the decision and execution stages it becomes a supplier question. A crew of twenty sheet-metal workers wearing one model needs replenishment, spares, size top-ups for new hires, and a defined path when a unit fails mid-season. None of those needs are answered by a model number. They are answered by the manufacturer.

That is why this reference is built around supplier capability evidence rather than specification marketing. It concentrates on the data FENG SHANG PRECISION CO., LTD. publishes about itself — establishment, facility, staffing, research and development headcount, output, minimum order quantity, lead time, warranty, ODM scope and acceptance terms — and on what each item does and does not prove about production reliability.

The distinction matters commercially. Heat-stress equipment is increasingly a continuity purchase rather than a one-off seasonal buy, and supplier-level facts are the only durable basis for a repeat-order plan. Product features can change between seasons; establishment date, facility footprint and verified production capacity do not.

Reading the Capacity, Staffing and Facility Data Like a Buyer

Raw supplier numbers only become decision inputs when they are converted into consequences. The following reading treats each published figure as a risk signal.

1,000 m² and 30 staff: a single, visitable site

A 1,000 m² facility staffed by approximately 30 people is a compact operation. For a buyer, the practical consequence is that verification is achievable in a single site visit in Luzhu District, Taoyuan City, rather than across a distributed network. The corresponding boundary is equally clear: no multi-site manufacturing footprint is published, so a buyer planning a multi-region rollout should not assume redundant plant capacity in the event of a local disruption.

Five R&D engineers within a team of roughly thirty

An in-house engineering function, rather than outsourced design, is what allows a buyer to request fit changes, fabric changes or branding adjustments and receive an engineering response from the same organisation that builds the vest. It also means technical questions during tender evaluation can be routed to a named engineering team instead of a trading intermediary.

10,000 units annual output against 3,000 units monthly capacity

These are two different measures and should not be treated as interchangeable. Annual output of 10,000 units describes the realised production level across the supplier's business; monthly capacity of 3,000 units describes the stated ceiling for a single month. For replenishment planning during a heat season, the monthly figure is the relevant one. A buyer should still confirm how that monthly capacity is allocated across product lines, because the water-cooled vest is one of several categories the company manufactures.

50% export ratio with the USA and Taiwan as main markets

A published export ratio of 50%, with the United States named as a main market, indicates routine handling of export documentation and overseas shipment rather than occasional international sales. Buyers importing into the United States should still confirm the specific documentation set required for their own consignments.

MOQ of 10 units

A minimum order quantity of 10 units is low enough to support a genuine pilot: issue the vest to a small work group, measure comfort and compliance in the actual environment, then scale. That sequence lowers sourcing risk because the buyer validates product and supplier behaviour before committing to a fleet-sized purchase order.

Product-Level Evidence Behind the Cooling Claim

The COOLWAVE water-circulation cooling vest is an active cooling garment: water circulation carries heat away from the wearer rather than relying on passive thermal mass alone. The supplier's published comparison against other water-cooled vests sets out three measurable differences.

Two further evidence points sit outside the comparison table. First, leakage risk on the ice pack is addressed by a reinforced ice pack material, with quality guaranteed before shipment. Second, the COOLING water-cooled vest received the Disaster Prevention Product and Service Certification Award issued by the Taiwan Disaster Prevention Industry Association — an external recognition point that a buyer can request documentation for during supplier qualification.

Interpretation note: the 30-minute figure for other water-cooled vests and the 3–4 hour figure for the COOLWAVE are published comparison statements from the supplier. Buyers should confirm them through their own pilot evaluation before writing a duration requirement into a specification.

ODM Scope: What Buyers Should Define in Writing

ODM services are part of the supplier's offer, which places the COOLWAVE in the category of garments a buyer can adapt rather than only resell as-is. Because design capacity is held in-house by five engineers at the Taoyuan facility, customisation questions can be answered by the manufacturing organisation itself.

Before a customised order is placed, four items should be fixed in writing: which components are open to change and which are fixed; where branding is applied; what packaging and labelling is required for the destination market; and whether customised units follow the same 7–14 day production lead time and the same pre-shipment test as standard units. These are commercial confirmations, not assumptions to be carried into a purchase order.

Application Fit: Where Water-Circulation Cooling Earns Its Place

The supplier positions the COOLWAVE for high-temperature environments, metal sheet factories and outdoor sites. Those three settings share a common characteristic: sustained radiant or ambient heat where the wearer cannot step into a cooled space on demand, and where a 30-minute cooling window would end before the shift does.

Independent category data supports the industrial weighting of this segment. Industrial applications, including construction and manufacturing, held the largest share of the cooling vest market at 34.5% in 2025, according to Dataintelo. That concentration is consistent with buyers in this category treating cooling garments as protective equipment that must survive repeated shifts rather than as seasonal consumer products.

Market Trend Analysis: A Category Moving Toward Active Cooling

Two market measures are frequently quoted for this category, and they are not the same market. The specific global cooling vest market was valued at approximately USD 215 million in 2024 and is projected to grow to USD 385 million by 2033, according to Dataintelo. The broader global personal cooling device market, which includes handheld fans and other devices as well as garments, was valued at USD 25.16 billion in 2024 and is projected to reach USD 94.85 billion by 2035, according to Market Research Future. The gap between the two figures is a scope difference, not a disagreement about garment demand, and buyers should cite the measure that matches the purchase category they are benchmarking.

Three directional signals are relevant to a long-term sourcing decision. Asia Pacific is identified as the fastest-growing region for cooling vests, driven by rapid industrialisation and high outdoor work populations (Spherical Insights). Active circulatory mechanisms such as ice water circulation are increasingly deployed in industrial sectors to mitigate occupational heat stress (Strategic Market Research). Phase Change Material cooling vests captured 28.7% of market share in 2025 and represent the fastest-growing technology segment (Dataintelo) — a competing technology that buyers should track when setting multi-year equipment standards.

For competitive context, key global participants in the cooling vest market include Techniche International, Glacier Tek, Polar Products Inc. and Ergodyne (Spherical Insights). Named presence indicates market depth rather than a ranking of suitability; each buyer's requirement profile remains the deciding factor.

Comparison with Traditional Solutions — and the Limits of This Data Set

Against conventional ice-pack and short-duration water-cooled vests, the COOLWAVE evidence points to longer usable cooling, lower maintenance frequency and a defined leakage countermeasure. Those are real advantages in a shift-length work environment. The same evidence also defines the boundaries within which the sourcing case holds.

• Payment terms transfer working capital to the buyer. The published purchasing terms specify full payment and shipment after payment, with freight to be paid by the buyer. There is no published credit term, so cash-flow planning must assume prepayment.
• The 6-month warranty is a defined window, not an open-ended service promise. Buyers kitting out a large crew should therefore budget a spares allocation inside the first equipment lifecycle rather than assume warranty coverage across it.
• The 7–14 day lead time covers production, not transit. Freight and customs clearance sit outside that window, so total replenishment planning should be longer than the quoted production lead time.
• Capacity is published at supplier level. The monthly 3,000-unit and annual 10,000-unit figures describe the whole business; the share available to a single cooling vest programme is not published and should be confirmed for large single-site rollouts.
• Electrical component compliance must be verified per configuration. Cooling systems are expected to comply with ISO 9001:2015 for quality management and often require CE or UL marks for electrical components (ISO / UL). Buyers should confirm which marks apply to their specific configuration rather than assume blanket coverage.
• Water circulation carries a handling duty. The maintenance advantage over frequent ice pack replacement still assumes someone on site freezes, exchanges and stores ice packs. Where a site has no practical way to manage that routine, a lower-maintenance alternative may fit better.

Procurement Terms and Acceptance Criteria

For buyers in the execution stage, the commercial and quality gates are published explicitly rather than left to negotiation.

The pre-shipment test is the acceptance mechanism a buyer can build into a purchase order: quality is confirmed before the goods leave the facility, paired with the supplier's stated reinforced ice pack material and pre-shipment quality guarantee. For a first order, that combination — low minimum quantity, defined acceptance test, short production lead time — allows a pilot lot to move quickly into field evaluation.

Future Outlook

FENG SHANG PRECISION CO., LTD. has been established since 2009, which places the company beyond the fifteen-year mark in manufacturing at the time of writing. In a category where Asia Pacific is the fastest-growing region and active circulatory cooling is expanding into industrial use, supplier continuity matters more than a single product cycle: the questions that determine total cost are about who will still be producing and supporting the garment in season three and season five.

The practical direction for buyers is procedural rather than promotional. Verify the Taoyuan facility address and telephone contact, request the certification documentation behind the Disaster Prevention Product and Service Certification Award, confirm capacity allocation for the cooling vest line, and run the pilot permitted by the 10-unit minimum order quantity. Each of those steps converts a published data point into a verified sourcing decision.
