With eight years of experience serving the U.S. market, KornnacCaps supplies empty gelatin and HPMC hard capsules to customers including supplement manufacturers. We support capsule selection, customization, quality documentation, U.S. import clearance preparation, and shipping coordination-helping your team move from supplier evaluation to delivery.
For established U.S. dietary supplement companies, selecting an empty capsule supplier involves product fit, quality documentation, and dependable delivery planning. Purchasing teams need clear specifications and supply arrangements. Quality teams need material and batch information. Production teams need capsules that work with their formulations, filling equipment, and schedules.
Whether you are qualifying an additional source or reviewing alternatives for an existing product, we can work from your current specifications and supplier approval requirements to discuss samples, documentation, and delivery plans.
Empty Gelatin and HPMC Capsules for Dietary Supplements
From qualifying a supplier for an established product to selecting a capsule for a new formulation, KornnacCaps offers material options to support your brand positioning, filling requirements, and purchasing plans.
Gelatin Capsules and Animal Source Requirements
We offer empty gelatin capsules in multiple sizes, with custom colors and printing to match your product presentation and production requirements. Samples and applicable technical documents are available to support quality review and filling trials.
If your product requires a specific animal source, such as bovine gelatin, let us know when requesting samples. We will review the material configuration and supporting documents with you and supply against the agreed specifications.
HPMC Capsules for Non-Gelatin and Vegetarian Products
For products with non-gelatin or vegetarian positioning, our HPMC capsules provide an alternative. We can supply composition information and applicable vegetarian or vegan declarations to support your material review.
Share your size, appearance, and ingredient requirements with us. We can discuss suitable configurations and samples for evaluation, including ingredient considerations for custom colors and printing.
Capsule Size Selection and Filling Trials
Your existing capsule specifications, filling machine model, fill characteristics, and acceptance criteria help us identify samples for your evaluation. Your team can then assess separation, filling, locking, and handling under its own production conditions.
If the capsule size is not yet finalized, we can discuss options based on the target fill weight and powder bulk density, with the final selection confirmed through filling trials.
Custom Capsule Colors, Printing, and Titanium Dioxide-Free Options
KornnacCaps supports custom colors, transparency, logo printing, and packaging. Send us an existing sample or design brief, and we can discuss available configurations and prepare samples for appearance approval.
For titanium dioxide-free projects, we review the requested material, color, and printing together. This includes checking both the capsule shell and printing ink composition against your requirements.
Once samples are approved, we supply according to the agreed material, size, color, printing, and packaging specifications. If your formulation is light-sensitive, let us know so your technical team can evaluate the capsule alongside the final packaging.
Technical Documents and Quality Controls for Supplier Qualification
To support your supplier approval process, we can provide applicable technical data sheets, specifications, composition information, and product declarations. Share your qualification checklist so we can coordinate the relevant documents and address questions from your quality team.

Quality Management and Traceability
Our quality management processes cover supplier evaluation, raw material and finished-product inspection, product review and release, deviation handling, change control, and traceability. These processes support batch acceptance, quality communication, and follow-up when questions arise.
ISO, FDA Registration, Halal, and Kosher Documentation
For qualification review, we can provide ISO 9001 and ISO 22000 certification documents and U.S. FDA registration information. Halal and Kosher certification documentation is also available for applicable products. If you have a specific Halal standard or certification requirement, share it with us so our quality team can confirm whether the available certification meets your needs.
U.S. Customs Clearance Documentation and Import Support
KornnacCaps includes U.S. customs clearance coordination in its order support. Our experience working with U.S. customers and their import partners helps us connect product documentation with shipment preparation.
Clearance Documents and Veterinary Health Certificates
Before dispatch, we coordinate supplier-side documentation with your team and import partners. This includes product descriptions, quantities, batch information, material sources, and shipment documents.
We can provide a clearance documentation package for the order, including a veterinary health certificate where required for the selected gelatin capsule shipment. The documents are prepared to support review by your designated U.S. customs broker.
Coordination with Your U.S. Customs Broker
Your team should have its broker review the documentation and confirm the applicable entry requirements before shipment. We support document preparation and related questions; your designated U.S. broker handles the local clearance process.
If your broker would like to review a sample veterinary health certificate, contact us to request one.

Responding to Additional Information Requests
If product or source information is requested during import review, we can provide the relevant supplier-side documents and coordinate with your team, broker, and logistics provider. We continue to support documentation communication as agreed for the order, helping your team coordinate receipt of the shipment.
Capsule Storage Conditions and Temperature-Controlled Shipping
Capsule storage and handling requirements are part of our delivery planning. We discuss packaging, loading, and temperature control so your team can prepare suitable receiving and storage arrangements.
Storage and Handling Conditions
Our storage guidance specifies a temperature of 10–25°C (50–77°F) and relative humidity of 35–65%. Protect capsules from direct sunlight during transportation and transfer. Loading, unloading, and transfer operations should take place in a cool, ventilated, dry indoor environment.
Container Temperature Before Loading
When ambient temperatures exceed 30°C (86°F) in summer or fall below 10°C (50°F) in winter, precondition the container interior to 20°C (68°F) and allow the temperature to stabilize before loading or transfer. This helps avoid abrupt temperature changes during handling.
We communicate these handling requirements as part of shipping coordination so that loading and transfer arrangements align with the order plan.
Balancing Product Protection and Freight Costs
For bulk U.S. orders with suitable lead times, we recommend considering temperature-controlled ocean freight using a reefer container. Controlled container conditions help provide a more stable transport environment, while ocean freight allows shipping costs to be planned around shipment volume and delivery timing.
We can discuss transport options based on your quantity, route, and required arrival date. We also provide storage and handling guidance to help your receiving team prepare warehouse conditions and complete the agreed arrival checks.
Capsule Samples and Repeat Order Support
From initial qualification to repeat orders, we work with your team to coordinate samples, specifications, and order preparation. As purchasing continues, we can discuss production and shipping plans against your demand forecast and target delivery dates. Changes to an agreed specification are discussed with your team for evaluation.
Samples for Filling Trials, Testing, and Color Matching
Filling trials: We can provide 500–1,000 capsules of the same requested type and size for an initial machine evaluation.
Laboratory testing: Tell us which parameters you intend to test so we can discuss suitable samples for the evaluation.
Color matching: Send your formulation details or reference capsule sample. We can prepare hand-matched color samples for appearance approval. These may consist of only a few capsules and are intended primarily to confirm color.
Sample Costs and Preparation Time
Samples are provided free of charge, with shipping costs paid by the customer. Preparation typically takes 1–2 weeks, depending on the request, excluding transit time.
U.S. Customer Case Study: From a 10-Carton Trial to Repeat Orders
Supplier Evaluation and Factory Visit
A U.S. customer was evaluating a new capsule supplier after unresolved service issues with its existing local source. The customer had been in contact with our sales manager for some time but took a careful approach to changing suppliers.
Its China-based purchasing representative visited our facility to review the automated production lines, manufacturing processes-including the absence of an ethylene oxide sterilization step-and management practices. The customer also compared the full landed cost of purchasing from KornnacCaps, including freight and customs clearance expenses, with its existing local procurement costs.
Import Documentation and the First Air Shipment
The next challenge was importing capsules from China for the first time. We supplied documentation, including a veterinary health certificate for the gelatin capsule shipment, for review by the customer's U.S. customs broker. Because the broker also lacked prior capsule import experience, the customer decided to begin with a smaller shipment.
The first order consisted of 10 cartons shipped by air, supported by the clearance documentation we provided. The shipment cleared customs and was received by the customer. A reefer-container order followed soon afterward.
Repeat Purchasing and Custom Requirements
The relationship has since developed into repeat purchasing. The customer also brings us custom requirements from its own customers, which we address through coordination among our R&D, production, and quality teams.
Discuss Your Next Capsule Supply Project
If you are adding a capsule supplier or evaluating an alternative for an existing product, send us your current specifications and qualification requirements.
Include the capsule material, any animal-source requirements for gelatin, size, color, printing, expected quantity, destination, and target delivery date. Our team can then discuss suitable products, samples, documentation, and a quotation for your project.
