Sourcing conversations move faster when both sides use the same vocabulary correctly. This glossary covers the material, construction, certification, and trade terms that come up repeatedly in commercial inflatable sourcing — organized so you can look up an unfamiliar term mid-negotiation rather than guessing at what a supplier means.

Material & Construction Terms

• PVC Tarpaulin — the coated woven fabric base material for commercial inflatables, rated by weight (g/m² or denier).
• Drop-Stitch — a construction method using thousands of internal threads connecting top and bottom fabric layers, producing a rigid, flat panel at high pressure.
• Welded Seam — a high-frequency thermobonded joint between fabric panels, more durable than a sewn seam.
• Sewn Seam — a stitched fabric joint, generally lower-cost but more prone to leak over time than a welded seam.
• Airtight (Sealed-Air) Construction — a design that holds pressure without a continuously running blower once inflated.
• Constant-Air Construction — a design requiring the blower to run continuously to maintain shape.
• Denier — a unit measuring fabric thread thickness; higher denier generally indicates a heavier-duty material.
• TPU (Thermoplastic Polyurethane) — an alternative coating material to PVC, often used where higher abrasion resistance or eco-positioning matters.

Certification & Compliance Terms

• EN 14960 — the European standard for inflatable play equipment safety. See our EN 14960 vs ASTM F963 comparison for which standard your target market actually demands.
• ASTM F2374 — the US standard covering inflatable amusement device safety.
• CE Marking — a conformity marking indicating a product meets EU health, safety, and environmental requirements.
• TÜV — a German testing and certification body whose approval is commonly requested for DACH-region installations.
• RPII — a UK/Ireland inspection body for inflatable play equipment.
• PIPA Tag — a UK registration tag confirming an inflatable has passed inspection against BS EN 14960.

Trade & Logistics Terms

• MOQ (Minimum Order Quantity) — the smallest order volume a supplier will accept, which varies significantly by product category. See our MOQ reality check by category for realistic minimums.
• FOB (Free on Board) — a trade term where the buyer arranges and pays for freight from the port of origin.
• CIF (Cost, Insurance, Freight) — a trade term where the seller covers cost, insurance, and freight to the destination port.
• HS/HTS Code — the harmonized classification code determining customs duty rates.
• OEM (Original Equipment Manufacturer) — a supplier producing goods to a buyer's own branding and specifications.
• ODM (Original Design Manufacturer) — a supplier providing its own design, customizable with buyer branding.
• Container Loading — the practice of planning shipment volume around standard 20ft or 40ft HQ container capacity. Our container loading guide covers the capacity math by unit type.

Product Format Terms

• Combo Unit — an inflatable combining two or more functions (bounce area plus slide, for example) in one structure.
• Wet/Dry Combo — a combo unit configurable for either water play or dry bounce use.
• Air Dancer (Tube Man) — a tall, thin inflatable figure animated by a blower, used for outdoor advertising.
• Freefall Jump — a platform-and-landing-cushion format where participants jump from height onto an air-filled landing zone.
• Water Slide (Wgame) — a standard commercial inflatable water slide format, distinct from a slip-and-slide or splash-pool format.

Operations Terms

• Blower (Fan Unit) — the electric fan supplying continuous or intermittent air to maintain inflation.
• Anchor Point — a reinforced attachment point for stakes, sandbags, or water barrels to secure a unit against wind.
• Duty Cycle — the rated continuous-use tolerance of a unit, relevant for fixed installations versus occasional rental use.
• Field Repair Kit — a stocked kit of patches, adhesive, and tools for on-site minor repairs. See our field repair kit guide for what to stock.

FAQ

Is EN 14960 the same requirement everywhere in Europe?
EN 14960 applies EU-wide as the baseline standard, though some countries layer additional national or municipal inspection requirements on top of it.

What's the practical difference between FOB and CIF for a first-time buyer?
FOB shifts freight arrangement and cost to the buyer, giving more control but more logistics responsibility; CIF is simpler for a first order since the supplier handles freight and insurance, typically at a built-in premium.

Does OEM always mean a fully custom product?
Not necessarily — OEM covers branding to a buyer's specifications on an existing product line, while a fully custom mold or design typically falls under ODM or a bespoke development arrangement.

Do drop-stitch and constant-air construction refer to the same thing?
No — drop-stitch describes the internal thread structure that lets a panel hold a rigid flat shape, while constant-air describes whether the unit needs a running blower to stay inflated. A unit can combine both, use drop-stitch for rigid platforms while remaining constant-air overall, or use drop-stitch with a sealed valve for an airtight paddleboard-style product.
