Candle & Wax Product Inspection China: QC for Scented Candles, Wax Melts & Candle Containers | $169
Scented candles and wax melts are a high-volume, high-margin Amazon FBA category — but they also carry unique safety risks.
Scented candles and wax melts are a high-volume, high-margin Amazon FBA category — but they also carry unique safety risks. Glass container thermal stress, lead-contaminated wicks, and inconsistent fragrance throw are the top complaints driving returns and reviews. Pre-shipment inspection catches these before they reach your customer.
What does a candle and wax product inspection cover?
A standard PSI for candles and wax products checks: wax quality and composition, wick type and centering, container integrity (glass/metal/ceramic), fragrance consistency, burn test verification, and safety labeling compliance. For wax melts, the inspector also checks melt uniformity, packaging seal integrity, and dimensional consistency.
Step 1: Wax quality and composition check
The inspector verifies wax type (soy, paraffin, beeswax, coconut blend) against your spec. Visual and texture checks catch impurities, discoloration, frosting (white crystalline bloom on soy wax), and shrinkage cavities. For scented candles, the fragrance oil load is verified to be within the agreed percentage — typically 6-10% for soy candles.
Step 2: Wick inspection — material, centering, and trim
Wick quality is critical for safe burning. The inspector checks that wicks are lead-free (cotton or wooden wicks only — lead-core wicks were banned in the US in 2003 but still appear in uncertified Chinese production). Wick centering within ±1 mm ensures even burning and prevents glass cracking. Wick trim length is also checked — wicks longer than 5-6 mm can cause smoking and sooting.
Step 3: Container integrity — glass thermal stress testing
Glass candle containers are the #1 liability risk. The inspector checks for: thermal shock resistance (the container must withstand the heat of a full melt pool without cracking), glass thickness uniformity, sharp rim edges, and any chips or bubbles. Metal and ceramic containers are checked for lining integrity (rust-proofing for tin containers) and handle attachment strength.
Step 4: Fragrance and color consistency
Using a panel approach, the inspector compares the finished candle's hot and cold throw against the approved gold standard sample. Color matching is checked under daylight-equivalent lighting against Pantone reference. Any batch with noticeable fragrance variance (>15% from standard) or color drift (>ΔE 2.0) is flagged for rework.
Step 5: Labeling and compliance — ASTM F2417 and CPSIA
Candles sold in the US must meet ASTM F2417-17 fire safety standards and carry specific warning labels: "Burn within sight," "Keep away from children and pets," "Do not burn near flammable materials." For FBA listings, each unit needs an FNSKU barcode — the inspector verifies barcode scannability and label placement.
What are candle inspection fees?
CloudSpects charges from $169 per man-day for candle and wax product inspection in China. For a typical candle order of 1000-5000 units (AQL 2.5 level II), one inspector covers sampling, burn testing, and labeling in a single day. Multi-SKU candle sets may require 1.5-2 days.
What candle defects are most common?
From real inspection data: (1) Frosting and mottling on soy candles (~35% of visual defects), (2) Off-center wicks causing uneven burn pools (~25%), (3) Glass container cracks or bubbles from thermal stress (~15%), (4) Fragrance throw weaker than standard (~12%), (5) Missing or incorrect warning labels (~10%), and (6) Wick smoking due to improper trim (~3%).
