Importing Fragrance Products into South Korea: K-REACH and Labeling

South Korea maintains one of Asia’s most rigorous chemical and consumer product regulatory frameworks. For B2B importers bringing scented candles, reed diffusers, essential oils, or room sprays from China, compliance with K-REACH, KC certification, and Korean labeling standards is a prerequisite for customs clearance and legal sale.

K-REACH: Chemical Registration

The Act on Registration and Evaluation of Chemical Substances (K-REACH, Act No. 19112, effective 2019, amended 2023) requires any entity importing chemical substances above 1 tonne per year per substance to register with the National Institute of Environmental Research (NIER).

Practical implications for fragrance imports:

• A reed diffuser with 15 fragrance ingredients imported in 10,000-unit batches likely exceeds the 1-tonne threshold per substance, triggering registration.
• Candles with 8-10% fragrance load in 200g units contain 16-20g per unit. At 50,000 units annually, individual substances may or may not exceed 1 tonne depending on concentration.

Registration process:

1. Identify CAS numbers for all components above 0.1% w/w
2. Prepare toxicological and physicochemical data (reduced data set for substances below 10 tonnes/year)
3. Submit via ChemPortal (chemportal.go.kr); review takes 30-90 days
4. Receive registration certificate, referenced on labels and import documents

Costs and timeline:

• Registration per substance: KRW 3-20 million (USD 2,200-15,000)
• Consulting fees for foreign suppliers: KRW 5-10 million per project
• Total timeline: 3-6 months from identification to certificate

Note: Fragrance products inherently release chemicals (their function), so the “finished article” exemption rarely applies.

KC Certification

The Korea Certification (KC) mark is administered by KATS under the Framework Act on Consumer Product Safety.

Candles (HS 3406.00):

• Must comply with KC 1003: flame height limits, stability testing, drip resistance, heavy metal limits (lead wicks prohibited)
• Testing at KATS-accredited labs (KTL, KTR, FITI): KRW 300,000-800,000 per SKU
• Processing: 2-4 weeks from sample submission

Reed diffusers (HS 3307.49):

• Subject to Chemical Products Safety Act if containing hazardous chemicals above thresholds
• Child-resistant packaging required for harmful/toxic classifications

Electric diffusers:

• Require KC electrical safety certification (KC 60335) plus EMC testing
• Cost: KRW 1-3 million (USD 740-2,200)

Korean Labeling Requirements

All consumer fragrance products must carry Korean (Hangul) labels with:

1. Product name in Korean
2. Full ingredient list (Korean chemical nomenclature)
3. Net content (metric units)
4. Manufacturing and expiry dates
5. Manufacturer name and country of origin
6. Importer name, business registration number, and phone number
7. K-REACH registration numbers for registered substances
8. KC mark and certification number (applicable products)
9. Safety warnings in Korean (fire, children, flammability)
10. First-aid instructions

Format rules: Minimum 8pt font for mandatory info; labels must be affixed (not hang tags); Korean text cannot be smaller than any foreign text. Non-compliance triggers recall orders and fines of KRW 10-50 million (USD 7,400-37,000).

Customs Clearance

Busan Port handles 75% of containerized imports from China. Transit from Shanghai: 3-5 days.

Procedure:

1. Import declaration via UNI-PASS system by licensed customs broker
2. HSK classification (10-digit Korean extension of HS codes)
3. Documentary review: K-REACH numbers, KC certificates, labeling
4. Physical inspection (random or targeted; adds 2-5 days if triggered)
5. Duty and VAT payment, then release

Duty rates:

Product	HSK Code	Duty	VAT
Scented candles	3406.00-0000	8%	10%
Reed diffusers	3307.49-9000	6.5%	10%
Essential oils	3301.29-0000	0-5%	10%
Fragrance blends	3302.90-9000	8%	10%

Korea-China FTA: Under the 2015 agreement, tariffs are being phased down over 20 years. Importers should verify current preferential rates and ensure Form K certificates of origin are properly executed.

Cost Simulation: 5,000 Scented Candles

Cost Element	Amount (USD)
FOB cost (5,000 x USD 4.50)	22,500
Ocean freight (Shanghai to Busan)	1,200
Customs duty (8% on CIF)	1,900
VAT (10% on CIF + duty)	2,565
Broker fee and inland transport	440
Total landed cost	28,605
Per-unit landed cost	USD 5.72

At a retail price of KRW 42,000 (USD 31), this yields strong margins even after 40-50% distributor margins.

Practical Compliance Tips

1. Engage a Korean regulatory consultant for K-REACH (firms like REACH24H offer end-to-end services)
2. Pre-register substances during product development, not after orders are confirmed
3. Use Korea-China FTA preferences with valid Form K certificates
4. Affix Korean labels at the factory to avoid bonded warehouse relabeling costs
5. Maintain Korean-language SDS per MOE 16-section format
6. Leverage the 3-5 day transit from Chinese ports for rapid replenishment

South Korea’s regulatory environment demands upfront investment, but once established, compliance infrastructure supports efficient repeat importing. Combined with strong consumer demand and premium pricing tolerance, Korea rewards suppliers who commit to full regulatory compliance.
