On any consumer fireworks sheet, one product does two jobs nothing else can. It is allowed indoors when the rest of the assortment is not, ends up in a child's hand at a birthday party and in a bride's hand at a wedding send-off, and turns a fireworks container into a year-round seller instead of a four-week holiday play. That product is the sparkler (手持烟花 / 仙女棒) — the magic wand of the pyrotechnic aisle, and Liuyang ships more of them than any city on earth.
This guide is written for buyers sourcing wholesale sparklers from China — wedding planners building a recurring 28" gold sparkler line, party stores stocking shaped birthday cake sparklers, supermarket chains restocking the New Year aisle, and importers who simply want to add the easiest-clearing pyrotechnic SKU to their next mixed container.
What a Sparkler Actually Is
Strip the wrapper and a sparkler is the simplest device in the entire pyrotechnic catalog: a steel wire (or thin paper tube) coated with a slow-burning mixture of oxidizer + metal fuel + binder, with a short chemical primer at the tip and a bare handle at the other end. Light the tip, and the burn front travels down the coating at roughly 1 cm per second, throwing a shower of incandescent metal fragments outward as it goes. Nothing leaves the device. No flame projects more than a few centimeters from the wire. The user keeps it in hand the entire burn.
That single fact — handheld, no projectile, no aerial component — is why sparklers sit in their own legal universe. Most fireworks regulations treat them as the lowest-risk pyrotechnic on the catalog: UN0337 (1.4S) on a vessel, F1 / Category 1 in the EU, and ASTM F963 toy-safety territory in the US for the cake and birthday formats.
Composition is what decides the color and the burn. A traditional gold sparkler uses iron filings or aluminum in a barium nitrate / dextrin matrix — the burning iron throws the warm gold sparks every wedding photo is built around. Color sparklers swap iron for finer aluminum or magnalium and add a metallic colorant (strontium for red, copper for blue, barium for green). The classic Morning Glory tube sparkler (手持喷花) uses a denser charcoal-titanium-perchlorate composition packed in a paper tube, ejecting a continuous colored flame jet rather than scattered sparks.
The hand that holds a sparkler is doing what the hand that lit the first bamboo joint did a thousand years ago — keeping the fire close, holding it on purpose, watching the metal turn into light. The wire is new. The gesture is old.
— Liuyang factory floor, sparkler line, 2026The Five Build Families on a Liuyang Sparkler Sheet
On a real Liuyang catalog, "sparklers" is not one product. It is roughly five distinct build families, each engineered for a different end use, retail price band and destination market. Most importers see them mixed together on a category sheet without noticing the build family is the variable that decides everything about packing density, retail SKU shape and which compliance test the carton has to pass.
| Build Family | Format & Length | Burn Profile | Retail Pack | Tier |
|---|---|---|---|---|
| Wire Sparkler — Short | 7" / 8" / 10" steel wire | Gold or color, 30–60 sec | Box of 6 / 10 / 12 | Consumer (F1 / 1.4S) |
| Wire Sparkler — Long / Wedding | 18" / 20" / 28" / 36" wire | Smokeless gold, 90–180 sec | Box of 6 / 12 / 24, custom-printed | Event / Wedding (F1 / 1.4S) |
| Morning Glory (手持喷花) | 14" paper tube + handle | Color flame jet, 15–45 sec | Box of 6 / 12 | Consumer (F2 / 1.4G) |
| Birthday Cake Sparkler | 4" / 5" thin wire, food-safe coating | Smokeless gold, 30–60 sec | Box of 4 / 6 / 8 (HoReCa packs) | Indoor / Food-Contact (F1) |
| Shaped & Electric Sparkler | Heart, star, number, electric ignition | 20–60 sec, decorative | Custom event / cake-topper | Event & novelty |
The short wire sparkler is the entry product — the SKU that fills the Diwali, Lunar New Year and Independence Day retail aisles by the pallet. The long wire sparkler is the wedding category built around a photographer's 90-to-180-second burn window. Morning Glory is the colored-flame format Asia and Latin America stock for festivals. Birthday cake sparklers are the year-round HoReCa product. Shaped and electric sparklers are the premium upcharge — the SKU that lifts an event-rental margin from "candle level" to "showpiece level."
Effect Families Worth Carrying
A serious Liuyang factory keeps 30 to 60 active sparkler SKUs across the five build families. They cluster into three effect families. A retail assortment usually only needs all three in different lengths.
Gold Sparkler — The Classic Wedding & Diwali Effect
The original sparkler look: a warm gold shower from a steel wire dipped in iron-and-aluminum composition. This is the SKU every photographer's lighting test was built around — the warm 2700K cast matches indoor venue light better than any other pyrotechnic. The 18", 28" and 36" formats are the wedding-line workhorses; the 7" and 10" formats run the volume in retail party packs.
Color Sparkler — Red, Blue, Green, Multi
Steel wire dipped in a metallic-color matrix — strontium red, copper blue, barium green, sometimes alternating along the wire so the burn cycles through the spectrum. Color sparklers throw shorter sparks than gold and burn a touch hotter, which is why they sit under EN 14035 with a slightly larger user safety distance. The strongest demand is in retail party packs where the rainbow effect is the entire selling point.
Morning Glory & Tube Sparkler — Colored Flame Jet
A different build entirely: a paper tube packed with composition, lit at the open end, ejecting a continuous color flame instead of scattered sparks. Morning Glory (手持喷花) is the flagship — a 14" handle that throws a 15–45 second total color flame, cycling through 3–5 distinct colors with each color burning roughly 6–8 seconds. The Fire Spurter format scales the same idea up to 12" / 8" jets for stage and outdoor event work.
Rule we use when building a sparkler assortment for a new market: one short wire SKU + one long wire (wedding) SKU + one Morning Glory tube covers 80% of consumer demand. Add a 4" cake sparkler for HoReCa and the category sells itself year round, with peaks at Lunar New Year, Diwali, July 4th, wedding season (May–October) and the December holiday run. Match the wire length to the destination certificate — a 36" stick that cleared in the GCC may need to be substituted for an 18" version on a UK shipment.
Featured Series from the Liuyang Catalog
A snapshot of the sparkler SKUs we ship most often — built and packed in our own factory in Chengchong Town and bundled into mixed containers across the wider Liuyang fireworks product range. The full Sparkler category sits at category 9 of our wholesale catalog and connects directly to the rest of the consumer sheet through the complete category guide.
Beyond the standard catalog, we also run shaped sparklers (hearts, stars, numbers 0–9, "LOVE", custom logos) on a separate cake-topper line, plus food-contact birthday cake sparklers in 4" and 5" lengths packed for HoReCa accounts. Those sit on a different sheet because the printed shape and food-grade coating are quoted per design — ask for the shaped sparkler & cake-topper addendum when you request a quote.
Why Sparklers Are the Easiest Pyrotechnic to Put on a Container
Three reasons sparklers are the most freight-efficient firework on a mixed container.
- Lowest hazard class on the IMDG code. Most consumer wire sparklers ship under UN0337 (1.4S) — the same hazard division as a small fountain or a child's snap, and the lightest DG surcharge of any pyrotechnic class. Compared with a 1.3G Bateria container, the per-CBM freight cost on a sparkler-heavy mix is dramatically lower. Morning Glory tubes typically classify as 1.4G alongside cakes and candles.
- Highest revenue density. A sparkler retail pack is mostly product, not air — the wires nest tightly, the boxes stack, and a 20GP can hold 15,000+ retail packs alongside cake and candle volume. The revenue-per-CBM ratio is the second-highest in the consumer catalog after firecrackers. That makes sparklers the most profitable filler on a mixed container.
- Simplest paperwork at destination. In the US, wire sparklers under specific NEC and length thresholds are exempt from the formal CPSC fireworks framework in many state-level rules and clear under ASTM F963 toy safety territory for the cake / kids formats — the same regime as a toy car. In the EU, sparklers are the canonical F1 reference product and the only firework allowed in supermarket retail year-round in many member states. The GCC, UK, Australia, Latin America and Southeast Asia run similar simplified frameworks.
For buyers new to fireworks importing, sparklers are usually the SKU we recommend on the first container — the format that builds confidence in the route, the broker, the customs clearance and the warehouse handling before the bigger Roman candle and cake volume comes in. The full mechanics of putting that first container together sit in our complete guide to importing fireworks from China; the calendar of when to book each season's sparkler volume sits in the 2026 sourcing calendar.
Telling a Good Sparkler from a Bad One
Sparklers fail in three places. After unpacking a few cases of cheap product, you stop reading the wrapper and start checking these three.
- Wire grade and coating thickness. A premium Liuyang sparkler uses a smooth-drawn steel wire of consistent diameter (typically 1.0–1.4 mm depending on length) with the composition extruded around it in a single, even coat. Cheap product shows a wavy, lumpy coat or visible wire underneath at intervals — both are recipes for a "skip" where the burn front jumps a section of wire and the spark output drops to nothing for two seconds. Run a fingernail down the wire; it should feel like one continuous cylinder, not a string of beads.
- Tip primer and ignition consistency. The first 5–8 mm of every sparkler is dipped in a faster, more sensitive priming composition that catches a match flame and transitions the burn to the main coating. A weak primer is the most common reason a "duff" sparkler refuses to light at a wedding — the lighter is fine, the wire just isn't catching. A good Liuyang primer ignites within 1.5 seconds of a normal Bic flame. Test five from the same box; all five should light on first try.
- Spark consistency along the wire and smoke profile. Every sparkler in the same SKU should produce the same spark length, the same color and the same smoke output across the entire burn. A wedding-grade gold sparkler should produce almost zero visible smoke indoors — that's the whole reason event venues accept them. A box where some sticks throw clean gold and others smoke gray-brown was filled with damp composition or contaminated raw material. This is the most common QC defect on cheap product, and it's instantly obvious during a test fire — the wider firing-line checklist sits in our guide to spotting high-quality fireworks.
Test-burn at least three sticks from each SKU before signing off on a pallet — and time them with a phone stopwatch. A clean Liuyang gold sparkler should burn to within ±5 seconds of the spec across the box (e.g. 28" gold sparklers burn 110–120 seconds, every time). A batch where times vary 30+ seconds is a process failure, not random variance. That's the test that catches a cheap supplier in 2 minutes.
How Sparklers Compare to Cakes, Candles & Fountains
Sparklers are the smallest, safest and most versatile product on the consumer shelf. They win on indoor use, year-round demand and the markets where the rest of the assortment is restricted.
| Format | Effect Profile | Hazard Distance | Indoor / Cake Use? | FOB Range (per unit) |
|---|---|---|---|---|
| Wire Sparkler — 7"–10" | Gold or color, 30–60 sec | 0.5–1 m | Permitted in most jurisdictions | $0.02–0.08 |
| Wire Sparkler — 18"–36" | Smokeless gold, 90–180 sec | 1–1.5 m | Wedding / event venues | $0.10–0.45 |
| Birthday Cake Sparkler 4"–5" | Smokeless gold, 30–60 sec | 0.3 m | Yes — food-contact rated | $0.04–0.18 |
| Morning Glory Tube | Color flame jet, 15–45 sec | 1–2 m | Outdoor only | $0.20–0.80 |
| Cylindrical Fountain | 60 sec ground | 5–8 m | No | $0.60–1.80 |
| 200g Multi-Shot Cake | 15–25 sec aerial | 20–25 m | No | $1.00–3.00 |
For the cake side of the assortment, see the 200g and 500g multi-shot cake guide; for the candle side, the Roman candle buyer's guide covers calibers and effect families; for the silent end of the consumer shelf, the fountain fireworks guide handles ground-only product. The single-bang format that traces back to the same Liuyang flash-powder lineage as everything else sits in the firecrackers wholesale guide.
Where Sparklers Sell, and Why They Sell Year-Round
Sparklers are the only firework with a five-peak demand curve rather than the one or two peaks the aerial categories live on. That curve is what makes them a year-round inventory product, not a holiday-only play.
- Lunar New Year (Jan–Feb). Hong Kong, Singapore, Malaysia, Thailand, Vietnam, the Philippines, plus the Chinese diaspora. Apartment-dwelling families lean on 7" / 10" wire sparklers across the 15-day window from New Year's Eve to the Lantern Festival — usually the only firework they're allowed to use.
- Wedding season (May–Oct globally). The 18", 28" and 36" gold wedding sparkler is now a default item on wedding-vendor checklists across the US, UK, Australia, the GCC and India. An 80-guest wedding goes through 100–150 sticks for a single send-off photo; a 200-guest Indian wedding 400+ across pre-wedding events.
- Diwali, Holi and Indian wedding season (Oct–Nov). India's domestic Sivakasi industry is large, but premium gold sparklers and shaped novelties are still imported from Liuyang for the upper end of the wedding and corporate market.
- Year-round HoReCa channel. Birthday cake sparklers, bottle sparklers (the 6" tube on a Champagne bottle at club service), and shaped number sparklers ("30", "50", "100") sell continuously through restaurant, bar and event-rental supply at a flat 12-month run rate — the channel that lets an importer hold inventory without a holiday pivot.
Two more peaks fill the calendar gaps. July 4th (US) and Canada Day push sparklers into nearly every retail family pack alongside cake and candle volume. Christmas and New Year's Eve / Hogmanay in Western Europe lean heavily on the 4" cake sparkler for indoor restaurant service and the 18" / 28" formats for outdoor countdowns — often the only firework allowed at indoor venues that night.
Sourcing Wholesale from Liuyang
Pricing & MOQ
Typical FOB ranges out of Liuyang for export-grade sparklers:
- 7" / 10" wire sparklers (gold or color) — $0.02–0.08 per stick, in retail boxes of 6 / 10 / 12
- 14" / 16" wire sparklers and Bristlegrass — $0.06–0.15 per stick
- 18" / 20" wire sparklers (wedding) — $0.10–0.20 per stick
- 28" / 36" gold wedding sparklers — $0.18–0.45 per stick, custom-printed retail boxes available
- 4" / 5" birthday cake sparklers (food-contact) — $0.04–0.18 per stick, in 4 / 6 / 8 packs
- 14" Morning Glory / Fire Spurter tubes — $0.20–0.80 per piece, by composition and length
- Shaped sparklers (heart, star, number, "LOVE") — $0.50–2.20 per piece, MOQ on custom shapes
- Electric / push-button sparklers — $0.40–1.20 per piece
MOQ is typically one mixed 20GP — roughly 800–1,200 cartons of fireworks, of which 200–500 cartons can be sparklers. Sparklers pack densely and ship under the lowest hazard class, so they're often the most freight-efficient filler on a mixed container loaded mostly with cake. Pure-sparkler containers are also routinely arranged for wedding-supply and party-store wholesalers — the lower DG class makes a sparkler-only 20GP a viable booking on most ocean lanes when the standard fireworks-mix vessel is full.
Custom-Printed Retail Boxes & Private Label
Most of the wedding-line and party-store volume out of Liuyang ships in custom-printed retail boxes — your brand on the sleeve, your barcode, your destination-language safety panel and (for wedding sparklers) the venue, couple's names and event date on the box if the buyer is a wedding planner. Standard private-label terms:
- MOQ per printed design: 500 retail boxes for a wedding sparkler print (28" / 36" formats), 1,000 boxes for a standard 4–24-stick consumer pack — lower than aerial product because the printed sleeve is light cardboard rather than a heavy cake outer.
- Artwork: we accept buyer artwork as PDF / AI / EPS at 300 dpi with bleed; in-house design support is available if you only have a logo. CE / ASTM / EN safety pictograms and the 13-digit EU registration number are added by us at the printing stage to match the destination certificate.
- Lead time: 25–35 days for printed retail boxes on top of the standard sparkler production run, ~45–55 days total from artwork sign-off to FOB Liuyang. Shaped sparklers (heart / star / number / "LOVE" / custom logo) and electric cake-topper formats add ~15 days for the shape die.
- OEM / private label: the entire retail SKU — composition, wire length, retail pack count, printed sleeve, outer carton barcode — can be quoted under your label. We do not ship a competitor's brand; private-label customers receive a written exclusivity letter for the printed design.
Compliance & Hazard Class
- EU (F1 / F2) — EN 15947 for wire sparklers, EN 14035 for handheld pyrotechnic articles, plus Pyrotechnic Articles Directive 2013/29/EU for the CE mark and a 13-digit registration number on every retail package. Most wire sparklers land in F1 (Category 1) — the indoor / under-12 tier — which is the only firework category sold year-round in supermarket retail in many EU member states. Morning Glory tubes typically sit in F2.
- US (CPSC / ATF / DOT) — Wire sparklers under the standard NEC thresholds clear as UN0337 (1.4S) for ocean shipment and are exempt from formal CPSC 16 CFR 1507 fireworks rules in many state-level interpretations, falling under ASTM F963 toy safety for the cake-topper and kids formats. State retail rules still vary — confirm which length/composition is allowed in your destination state before booking.
- UK (BS 7114 / BS EN 15947) — Sparklers are Category 1 indoor under the UK framework. Birthday cake sparklers and short wire sparklers (under 30 cm) are sold year-round in supermarkets without the seasonal restriction that applies to all other fireworks classes.
- UN classification — Wire sparklers ship under UN0337 (1.4S), the lowest fireworks hazard class on the IMDG code, which carries the lightest DG surcharge of any pyrotechnic. Morning Glory and tube formats may classify as UN0336 (1.4G) alongside cakes and candles — confirm classification on the test report before booking. The full UN classification framework for fireworks is in our UN numbers and shipping classifications guide.
- GCC, Latin America & Southeast Asia — Sparklers clear under simplified consumer-firework permits in most GCC, Latin American and Southeast Asian markets. The country-by-country GCC compliance map sits in our Middle East fireworks import hub; the Latin American import routes follow agencies such as DGMN (Chile), SEDENA (Mexico) or the Federal Police (Brazil), with sparklers usually the simplest SKU on the permit.
- China export side — Export shipments out of Liuyang are supported by CIQ inspection records and an AFSL export licence with a valid EX number for the destination market.
The single most expensive mistake on a sparkler container is the wrong wire length for the destination market. A 36" gold sparkler that cleared in the UAE may be over the residual-flame distance limit on a UK CE certificate; a 28" stick built for the US wedding market may need a different composition for an EU F1 label. Always confirm the destination test report and certificate before printing the retail box — the printing cost is the second-most expensive mistake to fix.
Why Liuyang on This Category Specifically
Sparklers look like the simplest firework on the planet. They are also the fastest to make badly. Composition has to be extruded at the right viscosity, the wire has to be drawn to a 5% tolerance, the dip line has to maintain temperature within ±2°C across an eight-hour shift, and the dry rack has to hold the sticks at a fixed angle so the coating doesn't pool. Every step has a window. Liuyang has the local ecosystem to keep all those windows tight: steel wire suppliers, composition extruders, automated dip lines, drying tunnels, and on-site CIQ test firing — all within the same industrial cluster around Chengchong Town that produces every other consumer pyrotechnic format. The wider Liuyang fireworks history traces the line from Tang-dynasty bamboo torches forward to today's wire sparkler — same gesture, different chemistry.
FAQ
What exactly is a sparkler, and how is it different from a fountain or a candle?
A sparkler is handheld — a steel wire or thin paper tube coated or filled with a slow-burning composition that throws sparks while the user holds it. Nothing leaves the device, no flame projects more than a few centimeters from the tip, and the user keeps it in hand the entire burn. That makes it different from a fountain (sits on the ground) and a Roman candle (fires aerial stars). Sparklers are the only firework most jurisdictions still allow at outdoor weddings, indoor venues with a permit, and on top of restaurant cakes.
Are sparklers regulated as fireworks in the US, the EU and the UK?
It depends on the format. In the US, wire sparklers are exempt from the formal CPSC fireworks rules in many states and ship under DOT UN0337 (1.4S) — the lowest hazard class on a vessel — with ASTM F963 toy safety applying to the cake / kids formats. In the EU, sparklers fall under the Pyrotechnic Articles Directive 2013/29/EU and EN 15947 / EN 14035, mostly at Category F1 (indoor / under-12) or F2. The UK uses a similar BS 7114 / BS EN 15947 framework. Bottom line: sparklers are the easiest firework SKU to import — but the test report still has to match the destination certificate.
What is the difference between a wire sparkler and a Morning Glory (手持喷花)?
A wire sparkler is a steel wire dipped in a metal-fuel composition (aluminum, magnalium, titanium or barium) — sparks fly off the burning coating but the wire itself does not move. A Morning Glory (手持喷花) is a paper tube packed with composition that ejects a colored flame jet from the open end while the user holds the closed end like a torch. The Morning Glory burns shorter (15–45 seconds versus 60–180 for wire), throws color rather than just gold, and ships under a slightly different test profile. The two formats are sold side by side in most retail sets.
Why are sparklers the easiest firework to put into a mixed container?
Three reasons. One — classification: most wire sparklers ship under UN0337 (1.4S), the lowest fireworks hazard class, with the lightest DG surcharge of any pyrotechnic. Two — density: a sparkler carton packs almost no air, and a 20GP can hold 15,000+ retail packs next to cake and fountain volume. Three — paperwork: in the US, EU, GCC and most of Asia, sparklers clear under a simpler import permit than aerial product. That combination makes them the highest revenue-per-CBM filler on any mixed container.
What lengths and burn times do Liuyang wedding sparklers come in?
The wedding-photography market typically asks for 20", 28" or 36" gold wire sparklers because the burn time matches a send-off line. Approximate burn times: 10" wire is ~45 sec, 20" is ~90 sec, 28" is ~2 min, 36" is ~3 min. We pack the long formats in 6, 12 or 24-stick retail boxes with smokeless gold composition rated for indoor venues that permit them — the same wire size your photographer's lighting test was built around. Custom-printed retail boxes (with venue, couple's names, wedding date) are quoted on a separate sheet — minimum 500 boxes per design.
Can sparklers ship in the same container as cakes and roman candles?
Yes — and they should. Wire sparklers ship under UN0337 (1.4S) and Morning Glory tubes under UN0336 (1.4G), both fully compatible with the rest of a 1.4G consumer-fireworks mix in a single 20GP. The standard MOQ is one 20GP mixed with 200–500 cartons of sparklers alongside cake, candle and fountain volume. For high-volume wedding-supply and party-store wholesalers we can also arrange a sparkler-only 20GP, which often clears at a lower DG surcharge than a mixed-fireworks load.
