Contract Packing for Powders and Tea in Vietnam: Stick Packs, Tea Bags and Bring-Your-Own Materials

2026年11月14日

Short answer: Contract packing (co-packing) means the factory fills and seals product into your chosen format, often using ingredients or packaging you supply. It is a low-risk way to start, because you can use an existing formula and the factory handles filling, sealing, coding and cartoning. Agree in writing who supplies what, how losses are counted, and what documents must accompany imported ingredients.

TOC

Typical formats

Stick packs: narrow sachets for powder, instant drinks, supplements and sweeteners.
Sachets and flat pouches: single-serve spice, seasoning or powder.
Tea bags: string-and-tag, pyramid or envelope bags; filter material (PLA, nylon, paper).
Drip bags: see Vietnam coffee OEM.
Stand-up and zipper pouches: bulk or retail packs.

Bring-your-own vs factory-supplied

Item	You supply	Factory supplies
Ingredients / bulk product	Possible, with import documents	Factory buys locally
Packaging film, boxes	Possible; confirm film specs for the machine	Factory sources; printing MOQ applies
Artwork	Always you	Factory may review for line compatibility
Filling, sealing, coding	Factory	Factory
Carton and pallet	Either	Either

Imported ingredients or materials need customs clearance into Vietnam, and some inputs may need import permits or be restricted. Ask the factory what is needed and whether it can act as importer.

Specs to give the factory

Product: powder particle size, flowability, hygroscopic behaviour.
Fill weight and tolerance (for example ±x%); give your own tolerance, not a generic one.
Film structure and barrier (aluminium or metallised film for moisture and aroma protection) and seal type.
Printing: coding position, batch and date format, language of the label.
Pack count per outer carton, carton marking and palletising.
Shelf life and storage conditions.
Test requirements: moisture, microbiology, metal detection.

Conditions factories commonly ask for

A minimum run per SKU and per pack format.
A written specification and approved artwork before film is printed.
A trial run, with sample approval before the main run.
Agreed yield and loss allowance for powder and tea.
Responsibility terms for imported materials that fail inspection.
Prepayment or deposit for materials.

Quality and compliance

For supplements and nutrition powders, the factory’s GMP and certification matter, and destination rules for claims and ingredients apply (US FDA dietary supplement rules, Japan’s health food rules, EU novel food and claims). See certifications compared.
