Assignment to 3301.29.41 covers all grades—crude, rectified, or fractionated—provided they originate from Syzygium aromaticum and derivatives. Import/export processes must validate physical origin and batch traceability, especially for pharmaceutical or food-grade uses. Incorrect customs declarations can trigger delays or reclassification assays at the border. |
Clove Oil: Technical Properties, Manufacturing Process & Safety Guidelines
Physical & Chemical Properties
Physical State & Appearance
Industrial clove oil presents as a clear to pale yellow or brownish liquid. The color and transparency show variation according to the choice of clove source and distillation endpoint. Odor is distinctly spicy and characteristic of eugenol, the principal aromatic constituent. Form is liquid at ambient conditions. Bulk melting point and crystallization issues rarely arise in storage but can affect filtration if cooled below typical plant temperatures.
Boiling Point, Flash Point, Density
Boiling range is grade-dependent, influenced by the proportion of eugenol and minor constituents. Trace fractions or residues from plant matrix extraction affect distillate sharpness and may shift volatility. Flash point requires careful batch control as higher terpene content decreases flash resistance, posing higher ignition risk during solvent stripping or drum filling. Density falls within a common range for essential oils, but shifts slightly between pharmaceutical and technical grades, and alters during cold storage due to variable solubility of minor terpenes.
Chemical Stability & Reactivity
Eugenol’s phenolic structure drives most reactivity, supporting both oxidation and slow resinification under air and light. The oil absorbs oxygen, leading to gradual color change and thickening. Antioxidant dosing or nitrogen blanketing is used in sensitive applications, especially in fragrance and food ingredient grades.
Solubility & Solution Preparation
Clove oil dissolves in common organic solvents and vegetable oils. Water solubility is low; emulsifiers or cosolvents are used for aqueous formulations in cosmetic and pharmaceutical production. Mixing speed, temperature, and order of addition impact clarity and emulsion stability for downstream blending facilities.
Technical Specifications & Quality Parameters
Specification Table by Grade
| Property | Technical Grade | Pharma/Food Grade |
|---|---|---|
| Eugenol Content | Typical values depend on source and extraction efficiency | Higher requirement, subject to tighter internal QC criteria and regulatory standards |
| Color | Can show slight haze or deeper color due to plant pigments | Typically clear and lighter, with lower tolerance for suspended solids |
| Odor Intensity | May include woody or smoky undertones | More controlled, adjusted for flavor/aroma use |
| Density | Within expected essential oil range | Consistent with tighter range for blending |
Impurity Profile & Limits
Impurities originate from raw clove matter, extraction solvents, and process decomposition. Controls limit safrole, methyleugenol, and aldehydic traces. Cut-points for these impurities shift depending on food versus industrial use. Internal screening uses GC/MS and out-of-spec lots are segregated or reprocessed.
Test Methods & Standards
Quality checks rely on established GC methods to track eugenol and profile impurities. Color and clarity controlled via visual standards. Odor assessment done by qualified QC analysts. Microbial limits enforced for pharmaceutical grades. Full test regime aligns with internal SOPs and may reference food or pharmacopeial monographs for export or registration.
Preparation Methods & Manufacturing Process
Raw Materials & Sourcing
Sourcing selects clove buds, stems, or whole berries based on desired constituent profile. Origin country and plant age affect both eugenol yield and aroma composition. Sustainable practices and traceability become mandatory for food and pharmaceutical channels. Accepted lots must pass pesticide and heavy metal screens.
Synthesis Route & Reaction Mechanism
Most production uses direct steam distillation. Some facilities add water or modify pressure to control distillation temperature and minimize heat degradation of eugenol and terpenes. No synthetic synthesis used in mainstream supply, but fractionation processes may be applied post-distillation in certain regions seeking derivative purity.
Process Control & Purification
Process design targets maximum eugenol recovery, minimal degradation. Key parameters: steam purity, pressure regulation, contact time, and condenser temperature. Ineffective control raises resin or color impurity, risking low clarity or unstable batches. Secondary purification (e.g., vacuum distillation) used for high-purity or flavor/food grade material.
Quality Control & Batch Release
QC checks start with raw incoming inspection. In-process control charts distillation yield, eugenol content, and impurity footprint. Batch release depends on analysis of main and side fractions by GC, visual, and, where needed, microbiological clearance. Release specification tightens for regulated markets and is specifically defined for each product grade and export region.
Chemical Reactions & Modification Potential
Typical Reactions
Eugenol acts as a phenolic compound. Reacts with oxidizers, acids, and bases to form ethers, esters, or undergoes oxidative coupling. Downstream processes can convert eugenol into vanillin or isoeugenol for fragrance or flavor industry.
Reaction Conditions (Catalyst, Temperature, Solvent)
Specific conversions require controlled conditions. Acid or base catalysts, careful solvent selection, and tight temperature ranges avoid resinification, over-oxidation, or loss of volatile fractions. Commercial derivatives depend on tailored reaction sequencing.
Derivatives & Downstream Products
Clove oil’s main downstream uses include eugenol-based resins, vanillin synthesis, isoeugenol for perfumery, and methyl-eugenol for certain specialty aromas. Suitability for these depends strongly on upstream purity and the extent of terpene or aldehyde byproducts carried through the process.
Storage & Shelf Life
Storage Conditions (Temperature, Humidity, Light Avoidance, Gas Protection)
Drums require cool, dry, and shaded conditions. Exposure to heat, sunlight, and air increases oxidation risk, leading to darkened oil, off-odors, or thickening. Some facilities employ nitrogen or CO2 blanketing for critical grades. Temperature excursions, especially above 30°C, accelerate degradation.
Container Compatibility
Steel and food-grade plastic drums see routine use. Phenolic compounds in the oil attack certain rubbers and soft plastics, so seals and gaskets chosen for compatibility. Long-term storage in inert-lined containers preferred for export and pharmaceutical lots.
Shelf Life & Degradation Signs
Shelf life depends on handling, fill gas, and grade (less refined, higher terpene fractions age faster). Key signs of degradation: increased viscosity, deeper coloration, and faded aroma. Pharmaceutical and flavor grades receive accelerated aging studies; technical grades may see shorter recommended holding times.
Safety & Toxicity Profile
GHS Classification
Clove oil’s classification depends on eugenol and minor constituent content. Main hazard concerns: eye and skin irritation, respiratory sensitization, flammability. Labels and documents reference regionally-accepted GHS classification and pictograms as required.
Hazard & Precautionary Statements
Direct contact requires gloves and goggles due to dermal sensitization potential. Splashes in the eye can cause serious irritation. Oil vapor inhalation at process temperature may irritate nose or airways. Flammable liquid; ignition sources must be strictly controlled—especially during filling and drum transfer.
Toxicity Data
Acute toxicity derives mostly from concentrated eugenol content; ingestion or repeated skin exposure presents systemic toxicity. Safe use levels guided by recognized food, pharma, or workplace exposure limits, which depend on both grade and jurisdiction.
Exposure Limits & Handling
Engineering controls, exhaust ventilation, and personal protective equipment mandatory for large-scale handling. Chronic overexposure and repeated skin contact lead to sensitization. Actual workplace limits defined by internal policy or region-specific regulations, updated in line with toxicological data and regulatory changes.
Supply Capacity & Commercial Terms for Clove Oil
Production Capacity & Availability
Annual production output relies on reliable sourcing of Eugenia caryophyllata flower buds from established plantations, predominantly in Indonesia, Madagascar, and select regions in India and East Africa. Shifts in yield tie directly to harvest volumes and post-harvest losses, with dry weather or pest outbreaks causing output variance each season. For bulk industrial grades, capacity planning follows forecast demand from flavor, fragrance, and pharmaceutical sectors. Smaller volumes of high-purity oil, meeting strict content and purity specs, are batch-produced with yield limits determined by feedstock quality and extraction efficiency.
Lead Time & Minimum Order Quantity (MOQ)
For regular commercial grades, standard lead time after order confirmation typically spans 2–3 weeks, subject to raw material availability and batch scheduling. Elevated purity requirements or compliance with pharma or food standards may extend lead time owing to additional purification steps and batch validation. MOQ for general industry grades falls in the 180–200 kg range (one drum or one steel container), but can increase with bespoke testing, repackaging or custom specification requests.
Packaging Options
Industrial shipments utilize epoxy-coated steel drums, HDPE drums, or ISO tanks to prevent chemical interaction or cross-contamination. Packaging selection depends on order volume, purity grade, and client requests for food or pharma contact compliance. Small volume shipments for high-value or certified grades use tamper-proof, GMP-compliant containers with traceable barcoding. Drum liners or nitrogen blanketing are sometimes applied to minimize oxidation risk during transit.
Shipping & Payment Terms
FOB, CFR, and CIF terms remain standard, adjusted to client location and preferred carrier. For contract clients, annual volume agreements can secure allocation and fixed pricing windows within bounds of raw material fluctuation risk. Payment follows industry-standard LC at sight or TT in advance for export shipments, with credit available upon established account history and export insurance conditions.
Pricing Structure & Influencing Factors
Raw Material Cost Composition
Major cost driver remains the dried clove bud feedstock. Raw material costs anchor to fluctuations in annual harvest, weather disruption, and regional labor costs. Extraction yield, solvent losses, and reprocessing rejects further shape the cost base. For pharma and natural fragrance grades, multi-step distillation, filtration, and certification add proportionally larger cost increments relative to commodity grades intended for technical use.
Fluctuation Causes
Raw material market in tropical producer regions sees periodic price swings due to weather delays, fungal infestations, or export policy changes. Exchange rate shifts for Indonesian Rupiah, Indian Rupee, and US Dollar heavily impact landed cost in major export markets. Logistics bottlenecks or port closures during monsoon or peak demand months can further destabilize delivered prices, especially for large-volume commitments or tight delivery windows.
Product Price Difference Explanation
Grade, purity, and required certification account for the largest price differentials. Technical grades for non-ingestible uses allow higher eugenol impurity levels or residual moisture, lowering processing and test costs. USP/Ph. Eur./FCC grades demand tighter compositional controls, with batch COA and third-party analysis, reflecting higher production costs and insurance against batch rejection. Kosher, Halal, or Organic certification induces additional chain-of-custody accountability and fee structure. Packing size also shapes per-kilogram cost—smaller, certified lots priced higher due to repackaging and higher compliance burden.

Industrial FAQ
What is the concentration of eugenol in your clove oil product?
The Role of Eugenol in Clove Oil Manufacturing
Clove oil’s main component is eugenol. The presence of eugenol defines the oil’s primary function in most end-uses: flavors, fragrances, and applications that rely on its antiseptic and analgesic qualities. Businesses purchasing clove oil look for consistent eugenol content, since this chemical determines the oil’s potency, odor profile, and performance in processes like flavor compounding and pharmaceutical formulation.
Our Focus on Eugenol Content Consistency
We produce clove oil from Syzygium aromaticum flower buds using a distillation method that draws out eugenol in high yield. Industry literature and our own experience show that natural clove oil usually contains over 80% eugenol by weight. Our batches routinely yield eugenol concentrations in the 85% to 87% range, which suits the majority of needs in both technical formulations and flavor applications. We prioritize lot-to-lot consistency because industries relying on this oil—oral care, flavor manufacturers, animal health applications—have zero tolerance for production variances that impact activity, solubility, or regulatory compliance.
How We Measure and Report Eugenol Levels
Every batch of our clove oil undergoes gas chromatography analysis, using qualified reference standards for eugenol quantitation. The resulting chromatograms are reviewed and interpreted by our in-house analytical chemists. Results appear both on our Certificate of Analysis and in our ongoing quality control documentation. This practice reduces the risk of receiving off-spec material and enables our industrial users to maintain seamless operations for their downstream products.
Addressing Market Questions on Oil Purity
There is sometimes skepticism in the market regarding variance between natural and adulterated clove oil. Low-quality handling, blending with synthetic eugenol, or improper distillation can cause the eugenol percentage to drift out of accepted specification. We maintain full track-and-trace records for our raw materials and processing conditions, and openly share chromatographic results for each production lot. This ensures buyers understand what goes into our oil and what analytic basis informs our quality claims.
What Customers Can Expect From Our Clove Oil
Over years of manufacturing, many buyers tell us that they rely on our product’s eugenol concentration for both documentation and process stability. For example, oral hygiene formulators target eugenol specifications for mouthwashes and dental preparations. Flavors and fragrances require reproducible chemical profiles, not surprises. Every client receives a technical data sheet with each shipment, including recent eugenol test results. Custom dilution or concentration requests are also welcome—our production team can adapt batch strength upon order, provided the purity of eugenol is maintained and quality tests are completed before release.
The Importance of Transparency and Technical Support
If there are compliance or technical questions, our technical staff provides direct support. Regulatory audits and customer-driven QC checks have full access to our laboratory data. We believe manufacturers have an obligation to disclose full technical detail about primary actives like eugenol—without it, the supply chain can break down and confidence in the final application goes with it. Our commitment to analytic integrity and open specification reporting ensures every buyer knows the exact content of eugenol in our clove oil product.
What are your minimum order quantities and lead times for bulk clove oil purchases?
From the manufacturing floor to the finished drum, every drop of clove oil begins with careful sourcing and distillation at our facility. Buyers often ask about our minimum order quantities and production timelines, so here’s what we know works reliably after decades in botanical extraction and bulk supply.
Minimum Order Quantities: Framed by Extraction Yields
Our clove oil production follows annual crop cycles, with raw material sourced directly from established growers. The volume we process for a single customer starts at one full drum, which is 180 kilograms. Smaller scales present issues in purification efficiency and batch consistency, so we always encourage buyers looking for very modest volumes to coordinate with a larger purchasing cycle or consortium.
Bulk customers in the pharmaceutical, flavor, and home care sectors usually source 500 kilograms or more per batch to align with shipping economics and downstream demand planning. We consistently see the most cost-effective logistics with full-container (approximately 2 metric tons), as freight and packaging fees drop significantly at this break point.
Lead Times: Planning From Harvest to Delivery
Once a customer places an order, our standard lead time for bulk clove oil is four to six weeks. This timeframe accounts for distillation, quality control, and the necessary export pre-clearances. Orders during harvest peak are often processed faster, since distillation campaigns run at full capacity and our tank storage is stocked for scheduled dispatch.
Orders placed in the off-harvest months may see a slight increase in lead time. We store clove bud stock under controlled conditions, but larger runs still require time for quality assurance across eugenol and total oil content thresholds. Our experience tells us that transparent scheduling—especially ahead of seasonal demand spikes—helps everyone in the chain avoid costly rush fees and fractured supply.
Production Capacity and Consistency
Scaling up for global markets, we've invested in continuous distillation technology at our main site. Orders up to 20 metric tons monthly cycle through without interruption. Our technical team provides shipment samples, batch records, and quality assurance documents with every dispatch for traceability and regulatory compliance.
From a manufacturing perspective, we encourage committed buyers to plan annual call-off orders, especially for products with consistent annual draw. This approach secures supply over the full year, locks in production slots, and minimizes risk during periods of unpredictable market swings or sudden transportation bottlenecks.
Practical Solutions for Lead Time Challenges
We address sudden changes in order size or shipment requirements by maintaining a safety inventory for key partners. This flexibility supports customers managing retail promotions or product launches. Air freight can bridge urgent supply gaps, yet ocean shipment remains the backbone for environmental and cost reasons. A shared understanding of annual demand allows our operations group to synchronize manufacturing windows with customer forecasts, reducing overall lead time and cost-to-deliver.
Open logistics and operational planning keep our materials moving from field to factory floor, across the blending line, and onto your site. Our goal as the manufacturer remains straightforward: continuous, reliable supply, batch-tested quality, and clear expectations at every stage.
Can you provide the Material Safety Data Sheet (MSDS) and confirm if your clove oil complies with international shipping regulations?
Clear Requirements in Hazard Communication
Every batch of clove oil moving through our facility meets a consistent set of quality and safety standards. We maintain comprehensive Material Safety Data Sheets (MSDS) for each production lot, anchored to the latest global safety requirements. The MSDS for our clove oil outlines identification, hazard classifications, composition, safe handling procedures, and essential information for workplace and transit safety.
Complying With Global Shipping Regulations
Clove oil contains eugenol, a component that falls under hazardous substances in several logistics frameworks such as IMDG (sea), IATA (air), and ADR (land). Our compliance team reviews updated shipping codes and stays in active communication with regulatory authorities to verify that every outgoing shipment adheres to the current rules. Each drum or container receives accurate hazard labels per the relevant UN classification. We keep an updated Dangerous Goods Declaration and ensure our export documentation matches the latest international conventions for hazard communication.
Production Practices and Traceable Documentation
Our operations reflect a practical understanding of safety and legal obligations. From the production floor to finished goods dispatch, traceability underpins every order. Batch numbers, COA, MSDS, and related shipment certifications can be traced back to the original manufacturing date and process conditions. When customers request, our technical support staff provides MSDS along with supplementary documents explaining chemical identity, hazard pictograms, recommended PPE, and steps for storage or spill response.
Risk Reduction During Handling and Transport
Shipping clove oil calls for strict attention to containment, ventilation, and spill prevention. We use industrial-grade materials that resist corrosion and leakage. All drums or IBCs seal tightly, and gross weights and emergency information stickers conform to applicable codes for sea and air. Our logistics process includes bundling pads and secondary containment, reducing the risk of leakage in transit. Wherever international customs raise questions over compliance or documentation, our shipping team offers clarification or supporting paperwork, eliminating bottlenecks at ports and warehouses.
Staff Competence and Continued Training
Our staff, from production supervisors to logistics handlers, participate in regular safety and compliance training. We coordinate with independent auditors to audit our certifications, ensuring our compliance track record stays current and our documentation passes international scrutiny. By delivering on these processes, we support business continuity for our customers and partners who depend on trouble-free, regulation-compliant deliveries.
Moving Forward With Industry Demand
Markets in pharmaceuticals, flavors, and personal care demand that clove oil suppliers meet strict traceability, safety labeling, and regulatory transparency. We design our production and logistics approach with this reality at the center. Our direct manufacturing role means technical documents, hazard assessments, and compliance reports originate from our own plant, reducing uncertainty at every step in the distribution chain.
Open, Documented, and Responsible Manufacturing
With every inquiry, customers are given direct access to current MSDS and evidence of compliance with global shipping standards. The regulatory environment remains ever-changing, but our in-house processes and responsive technical staff keep our shipments ready for safe handling and the successful navigation of customs and transit checkpoints. We back our clove oil with documentation and safety standards built for real-world, international use.
