Primary Packaging (Double Inner Packaging)
A customized double-layer primary packaging system designed specifically for research-grade peptide APIs, consisting of：
sealed vial

aluminum foil composite pouch :

PET(outer) + Al Foil + PE/CPP (inner)
providing an excellent barrier against moisture, oxygen, and light, with:
WVTR (Water Vapor Transmission Rate) of ≤ 0.01 g/m²·24h

OTR (Oxygen Transmission Rate) of ≤ 0.01 cc/m²·24h·atm.

Light transmission approximately 0%

Effectively protects peptide APIs from hydrolysis, oxidation, and photodegradation, ensuring product stability throughout storage and transportation.
Each package is clearly labeled with essential product information, including:
Product name

CAS number

Batch / lot number

Manufacturing date

Expiry / retest date

Net weight

Storage conditions (“Store sealed, protected from light at 2–8 °C”)

Intended use statement (“For Research Use Only”)

Secondary Packaging
EPP (Expanded Polypropylene) Insulated Container

a closed-cell foamed structure with extremely low thermal conductivity, combined with excellent structural strength and cushioning performance
International Transport Ice Packs

manufactured with low-temperature-resistant laminated pouches and filled with polymer gel or phase change materials (PCM)
ensuring effective thermal insulation and reliable mechanical protection throughout cold-chain transportation.

providing sustained and controlled cooling to buffer temperature fluctuations and ensure safe 2–8°C (5~7 days) cold-chain transportation of peptide APIs.

Tertiary Packaging
A three-layer aluminum foil composite structure:
Outer layer – Kraft paper

High tear resistance, puncture resistance and structural strength
Middle layer – High-density polystyrene(PS) Insulation Layer

Low thermal conductivity
Inner layer – Thermal aluminum foil

high‑purity aluminum foil with excellent oxygen barrier, moisture resistance, and heat reflection capabilities
The three-layer structure works synergistically to provide comprehensive protection:
mechanical strength + thermal insulation + moisture barrier,
ensuring product safety and stability during transport and storage.

Professional Freight Forwarding Network
We collaborate closely with experienced freight forwarders specializing in pharmaceutical and chemical logistics, with service coverage across major global regions, ensuring secure handling, regulatory compliance, and efficient international transportation throughout the logistics process.

Standard Products
We support multiple international trade terms in accordance with Incoterms® rules, including：
CFR, CIF, CIP, and DDP.

Customs Clearance Assistance
To support customers in completing import customs clearance procedures at the destination, we provide comprehensive documentation assistance, including:
Harmonized System (HS) CodeCertificate of Analysis (COA)Material Safety Data Sheet (MSDS / SDS)Air Transport Safety Assessment Report

Actual transit time depends on the destination, transportation route and selected logistics solution.
A precise Estimated Time of Arrival (ETA) will be provided upon receipt and confirmation of the complete delivery details.

· North America / Europe: approximately 7–15 business days
· Other regions: approximately 10–20 business days
Once the shipment has been dispatched, a tracking number will be provided to enable real-time shipment monitoring.

Proactive Logistics Exception Monitoring
In the event of logistics exceptions, including transportation delays or transit disruptions, we will proactively monitor shipment status, promptly notify the customer, and coordinate with logistics partners to resolve the issue in an efficient and timely manner.

Damage or Quality Issue Handling
If the received product shows signs of damage, leakage, or quality deterioration potentially caused by packaging or transportation, customers are requested to provide photographic evidence along with the shipment tracking number.

A responsibility assessment will be completed within 3 business days, after which we will work with the customer to determine an appropriate and mutually agreed-upon resolution.
