High-VG E-Liquid | B2B Wholesale & OEM Manufacturing
High-VG E-Liquid is engineered for sub-ohm cloud production and smooth throat hits at higher wattages. Formulated with a baseline 70VG/30PG ratio up to 100% VG, this formulation utilizes high-viscosity vegetable glycerin to support dense aerosol generation. Available in bulk volumes (1L, 5L, 25L drums) for automated co-packing or fully packaged retail configurations (10ml TPD compliant to 100ml shortfills). Production integrates cleanroom compounding with automated clean-in-place (CIP) liquid mixing systems to eliminate cross-contamination across flavor runs.

Formulation
Formulations rely on strict stoichiometric balancing of USP-grade humectants and high-purity food-grade flavor compounds. Water content is tightly controlled below 0.5% using Karl Fischer titration to prevent coil spitting and popping during high-wattage activation. Nicotine feedstock is stored under an inert nitrogen blanket to arrest oxidation, maintaining peroxide values under strict threshold limits prior to final blend incorporation.
Flavor Profile
Standard catalog spans 40+ pre-developed profiles across dessert, fruit, menthol, and tobacco categories. Custom flavor matching requires a 14-day development window utilizing gas chromatography-mass spectrometry (GC-MS) reverse engineering to replicate reference samples. Thermal stability testing ensures flavor compounds do not degrade or caramelize excessively at coil temperatures exceeding 250°C.
Packaging
Bulk Industrial: HDPE food-grade carboys (5L/20L) and stainless steel intermediate bulk containers (IBCs) for automated filling lines.
Retail Finished Goods: PET/LDPE Chubby Gorilla-style unicorn bottles (10ml, 30ml, 60ml, 100ml shortfills) equipped with tamper-evident child-resistant caps (ISO 8317 certified).
Labeling: Custom branding, batch numbers, laser-etched production dates, and regional warning symbols applied via automated inline wrap-around labellers.
Quality Control
Raw material inspection requires Certificate of Analysis (CoA) verification for every incoming lot of VG, PG, and nicotine before releasing materials to the cleanroom. Compounding takes place inside an ISO Class 7 cleanroom environment. Inline refractive index checks and pH monitoring are conducted at three points during each mixing cycle. Finished batches undergo automated optical liquid level scanning and torque testing on bottle caps to verify seal integrity before warehouse release.
Testing & Documentation
Every production lot is accompanied by a comprehensive analytical package generated by in-house and third-party accredited laboratories:
GC-MS Testing: Verification of flavor volatile profiles and screening for restricted compounds (diacetyl, acetyl propionyl, acetoin).
Heavy Metal Screening: ICP-MS testing verifying lead, arsenic, cadmium, and mercury levels remain below detectable limits (<10 ppb).
Nicotine Assay Titration: Verification that actual nicotine concentration falls within +/- 5% of the target label claim.
Documentation Provided: Lot-specific CoA, MSDS/SDS, ingredients declaration, and heavy metal test reports.
OEM / Private Label
Contract manufacturing services scale from custom formulation development to turnkey retail packaging. Clients provide flavor briefs or reference benchmarks; internal flavorists formulate prototypes within 7 business days. Production lines feature fully automated bottleneck filling, induction sealing, and carton boxing capable of turning over 50,000 units per shift. Supply agreements accommodate tiered volume pricing and dedicated safety stock storage.
Compliance
Formulated and manufactured in alignment with global regulatory frameworks for nicotine delivery products:
EU/UK Markets: Formulations structured to support TPD (Tobacco Products Directive) notification requirements, including 10ml volume caps and child-resistant packaging standards. Target market filters available upon inquiry.
US Market: Ingredient sourcing aligned with FDA premarket tobacco product application (PMTA) scientific standards, utilizing established tobacco-derived or synthetic nicotine variants.
Facility Standards: Production facility operates under ISO 9001 quality management systems and cGMP guidelines.
Storage
Store in original sealed containers between 15°C and 25°C in a dry, well-ventilated area away from direct sunlight and oxidizing agents. Prolonged exposure to temperatures exceeding 30°C or direct UV light accelerates nicotine oxidation, shifting liquid coloration to amber and degrading flavor integrity.
Frequently Asked Questions
Q: What is the minimum order quantity (MOQ) for custom High-VG e-liquid formulations?
A: The MOQ for custom flavor formulations or private label runs is 500 liters per nicotine strength/flavor variant, which can be split across multiple bottle sizes during the co-packing stage.
Q: How do you ensure batch-to-batch consistency for large-volume wholesale orders?
A: All ingredients are measured by gravimetric weight rather than volumetric displacement using calibrated industrial load cells. Digital batch records log exact quantities, temperature parameters, and mixing speeds, cross-referenced against a retention sample kept for every production lot.
Q: Are your e-liquids compliant with TPD regulations for the European market?
A: Yes. For European distribution, we formulate and package liquids in 10ml TPD-compliant transparent containers featuring required health warnings, tactile triangles, and child-resistant closures, backed by full emissions testing data.
Q: What types of nicotine are available for bulk manufacturing?
A: We supply formulations utilizing USP-grade natural tobacco-derived nicotine freebase, pharmaceutical-grade nicotine salts (benzoic or lactic acid bound for smoother throat hits at high strengths), and high-purity synthetic nicotine.
Q: What is the standard lead time for OEM private label production runs?
A: Standard production lead time is 15 to 20 business days following formulation sign-off, label artwork approval, and raw material verification. Repeat orders with established bills of materials ship within 10 to 14 business days.
Q: How is nicotine degradation prevented during international shipping and storage?
A: All bulk and retail containers are purged with nitrogen gas prior to sealing to displace residual oxygen. Packaging utilizes UV-resistant opaque or amber materials to halt photochemical degradation during transit.
