Temu EPR Material Weight Estimator

Q: How is component weight calculated?

Weight equals the unfolded area divided by 10,000 multiplied by the material grammage in grams per square metre. The unfolded area depends on the component form: a box is 2 x (LW + LH + WH), a bag is 2 x LW, and a flat sheet is L x W. The calculator sums every component and exports the breakdown to CSV. Multiplying length by width by height by a material density is incorrect, because that measures a solid block rather than the packaging shell.

Q: Are the grammage values exact?

They are industry reference averages, for example E-flute corrugated about 550 and folding carton about 350 grams per square metre. Real grammage varies with fluting, grade and supplier, so confirm against your packaging spec sheet and override any value in the reference panel.

Q: Does this cover WEEE or batteries?

This tool focuses on packaging weight. Electrical, electronic and battery EPR schemes have their own rules and may be weight- or unit-based; consult your compliance provider for those categories.

Q: How do I calculate packaging weight for EPR reporting?

Component weight equals unfolded area divided by 10,000 multiplied by grammage in grams per square metre. The unfolded area depends on the component form: a box is 2 x (LW + LH + WH), a bag is 2 x LW, and a flat sheet is L x W. Sum every component per SKU and export the breakdown to CSV for your registration.

⚠️ Grammage values are industry reference averages (E-flute ~550, B-flute ~650, white card ~350, PE film ~60 g/m²). Weight = unfolded area × grammage. Always confirm against your packaging spec sheet before you file.

How EPR packaging weight works

EU/UK EPR fees are partly driven by the weight of packaging you place on the market. Estimate it per SKU before you register.

What EPR weight is

Extended Producer Responsibility (EPR) makes the seller responsible for end-of-life packaging. Fees in many schemes scale with material weight, so knowing the grams of cardboard, plastic, foam and metal per shipment is the first step to a correct declaration. It sits alongside other EU obligations such as the GPSR label requirement — the GPSR label generator builds the EU rep and traceability label for your listings.

The method

Packaging is a shell, not a solid block, so its weight comes from the area of material used — not from the volume the box encloses. The packaging trade measures this as grammage (grams per square metre), and that is what EPR schemes bill against.

Pick each component's material and its form — box, bag or flat sheet.
Enter the dimensions in cm and the quantity.
The unfolded area depends on the form:
Box = 2 × (LW + LH + WH) · Bag = 2 × LW · Sheet = LW
Component weight (g) = area (cm²) ÷ 10,000 × grammage (g/m²).
Sum the components for total packaging weight per SKU.

Worked example

Step	Value
Box, 20 × 15 × 5 cm, E-flute corrugated	—
Unfolded area = 2 × (300 + 100 + 75)	950 cm²
Convert to m²	0.095 m²
Grammage, E-flute	550 g/m²
Weight = 0.095 × 550	52.3 g

A common mistake is multiplying length × width × height by a material density. That treats the box as a solid lump of fibre and overstates the weight by roughly twenty times.

Reference grammage (g/m²)

Material	Grammage	Typical use
Corrugated E-flute	550	Small shipping boxes
Corrugated B-flute	650	Heavier outer cartons
Folding carton (white card)	350	Retail boxes
Kraft paper	90	Void fill, wrapping
PE film / poly mailer	60	Mailer bags
PP woven	90	Bulk sacks
PET blister	250	Clamshell packs
Aluminium laminate	45	Foil pouches
Bubble wrap	100	Protective wrap
EVA foam sheet	180	Inserts, padding

Industry reference averages — confirm against your packaging spec sheet. Export the component table to CSV for your EPR registration. For the rest of the EU compliance stack, the full Temu seller toolkit collects the other calculators in one place.

Temu EPR Material Weight — FAQ

What is EPR and why does weight matter?

Extended Producer Responsibility shifts end-of-life packaging costs to the producer/seller. Many EU and UK schemes charge fees proportional to the weight and material of packaging placed on the market, so an accurate weight per SKU is needed for a correct declaration.

How is component weight calculated?

Weight = unfolded area ÷ 10,000 × grammage (g/m²). The area depends on the component's form: a box is 2 × (LW + LH + WH), a bag is 2 × LW, and a flat sheet is L × W. The calculator sums every component you add and exports the breakdown to CSV. Note that multiplying length × width × height by a material density is incorrect — that measures a solid block rather than the packaging shell.

Are the grammage values exact?

They are industry reference averages (e.g. E-flute ~550, B-flute ~650, white card ~350 g/m²). Real grammage varies with fluting, grade and supplier, so read it off your packaging spec sheet and override any value in the reference panel — the totals update immediately.

Does this cover WEEE or batteries?

This tool focuses on packaging weight. Electrical/electronic and battery EPR schemes have their own rules and may be weight- or unit-based; consult your compliance provider for those categories.

Do I need EPR registration to sell on Temu in the EU?

If you place packaged goods on the EU or UK market you are an EPR producer and must register and report packaging weight. Temu enforces compliance for EU-bound listings, so an EPR registration number is typically required before you can sell. This calculator gives you the per-SKU weights your registration needs.

How do I calculate packaging weight for EPR reporting?

Component weight = unfolded area ÷ 10,000 × grammage (g/m²). The area depends on the component's form: a box is 2 × (LW + LH + WH), a bag is 2 × LW, and a flat sheet is L × W. Sum every component per SKU — this calculator exports the breakdown to CSV for your registration. Multiplying length × width × height by a material density is wrong, because that measures a solid block rather than the packaging shell.
