Packaging and Specification Statement
Product Form: White crystalline powder, HPLC purity ≥ 98.5% pharmaceutical research grade;
Graded packaging: Micro standard products are packaged in borosilicate glass bottles for anti-theft purposes, while small and medium-sized products are sealed in light proof glass bottles. For kilogram level batches, double-layer vacuum moisture-proof packaging and thickened cardboard drums are used to prevent light and oxidation throughout the process;
Supporting documents: Provide factory quality inspection certificate (COA), chemical safety data sheet (SDS), and purity testing chart for each batch;
Storage and transportation conditions: refrigerated at 2-8 ℃, dry, light shielded and sealed, with an unopened shelf life of 2 years;
Usage constraint: This product is only sold to units with legal research and development qualifications, limited to pharmacological research, formulation development, and impurity analysis

1, Transportation channel selection
Match compliant channels based on cargo volume and delivery requirements, use chemical exclusive logistics throughout the entire process, refuse ordinary civilian express delivery, and ensure stability in customs clearance.
-Sample small goods (10mg – 100g): International chemical express delivery, direct air delivery, suitable for receiving samples from laboratories in various countries, with high customs clearance rate and stable delivery time.
-Small and medium-sized batches (1g – 100kg): International air freight dedicated line, fixed storage space, traceable, suitable for scientific research small batch raw material export, fast delivery time, and controllable inspection.
-Large quantities of goods (over 100kg): sea freight full container load/consolidation, low cost, strong stability, suitable for mass research and development of raw materials for normal export.
2, International standardized packaging requirements
Strictly follow IATA and IMDG international transportation rules, adapt to long-distance cross-border transportation, prevent falling, moisture, leakage, and deterioration, and adapt to customs inspection standards.
-Inner packaging: Powder products are sealed with double-layer vacuum PE to isolate air and moisture, prevent moisture absorption and powder leakage; Trace standard samples are sealed in light shielded glass bottles with reinforced sealing to prevent leakage.
-Buffer protection: the bottle body and tank body are wrapped with bubble film, shockproof foam, and the clamping position is fixed to avoid damage caused by bumping and collision during long-distance transportation.
-Outer packaging: Thickened five layer corrugated cardboard box or compliant cardboard drum, reinforced with wrapping film as a whole, resistant to pressure and wear, suitable for cross-border loading and unloading, transfer and stacking scenarios.
-Outer box labeling: Unified pasting of product information in both Chinese and English, universal labeling, warning labels for avoiding light and moisture, and handling with care, with clear and standardized information for scientific research purposes.
3, Complete set of necessary documents for export (core customs clearance)
All document information should be consistent, truthful, and valid, to prevent errors, omissions, and false reporting, to ensure fast customs clearance and avoid delays in goods seizure.
-Bilingual MSDS in Chinese and English (16 complete versions, GHS compliance standards, within validity period)
-Goods Transportation Condition Appraisal Report (Universal Non hazardous Appraisal Report)
-COA quality inspection report, product purity testing chart
-Commercial invoice, packing list, customs declaration
