Buying acetate frames in Bangladesh

Under EU guidance, a plastic spectacle frame has its rims, bridge, lugs and temples made only of synthetic or artificial materials, and cellulose acetate is one of the common ones. Brands and optical chains abroad buy acetate frames for colour and pattern; optical shops in Bangladesh sell them glazed with prescription lenses. An acetate frame manufacturer in Bangladesh has to hold colour, shape and size from sample to bulk.

Roptan takes one brief and sources from verified makers. We compare quotes on one material, hinge and test basis, keep your approved colours as the reference, check the lab reports and inspect the packed bulk.

Kinds of acetate frame

Full-rim acetate frames

The acetate front surrounds each lens. Choose it for bold colours and patterns, where the front is the design, and for most prescription ranges.

Half-rim acetate frames

Acetate encloses part of each lens and a thin wire, usually nylon, holds the rest. Choose it for a lighter front that still shows the acetate colour.

Acetate and metal combination frames

An acetate front with metal temples, or metal core wires and parts, counts as a combination frame when it uses two material categories. Choose it for slimmer temples, and test both materials.

Other plastic frames

Cellulose propionate, nylon and polycarbonate are the other usual frame plastics, and the frame standard now covers 3D-printed frames. Choose one when its design or weight suits better than acetate.

Acetate sunglass frames

The same acetate front can carry plano tinted lenses as sunglasses. Choose it for a matching optical and sun range, but plan two test routes, one for each product.

How to specify an acetate frame

Size: Lens width, bridge and temple length in millimetres on the ISO 8624 boxing system, with tolerances, for each size you sell.
Material part by part: Name the material of the front, temples, core wires, hinges and screws. The answer decides whether the frame is plastic or combination, and which tests apply.
Colours: Give each colour a code and approve it on a physical sample. Keep a sealed approved sample per colour as the reference for the bulk.
Hinges and temples: Standard or spring hinge, and skull or library temples. Write the hinge type into the specification, since spring hinges have their own mechanical test.
Heat: Acetate is a thermoplastic, so ask for the dimensional stability test at elevated temperature, which matters for frames stored or shipped through hot months.
Metal parts: Ask for a nickel-release result on every metal part in skin contact, with its plating, even though the front is plastic.

Standards and rules for acetate frames

ISO 12870:2024 (EN ISO 12870:2025): The current frame standard for unglazed frames for prescription lenses. The 2024 text also covers frames made by additive manufacturing and from natural organic materials.
REACH nickel limit and EN 16128: Metal parts in direct and prolonged skin contact may release at most 0.5 µg/cm² of nickel a week. EN 16128:2025 is the reference test for frames.
EU medical device rules: Spectacle frames are class I medical devices under Regulation (EU) 2017/745, normally self-declared, and the brand selling under its own name usually carries the manufacturer's duties.
ISO 12312-1 for sun versions: ISO 12870 does not cover plano sunglasses. An acetate frame sold with tinted plano lenses is tested as sunglasses instead.

What moves the price of an acetate frame

Colours: each colour adds a sample, an approval and stock of that material to manage.
Metal parts: core wires, spring hinges and metal temples add parts and nickel tests.
Construction: a combination frame needs tests on both materials, not just one.
Design: a new shape needs drawings and approved samples before bulk; an existing model does not.

Lead times and delivery

We give no figure here, because time depends on the order. It grows with a new shape, with many colours to approve, with spring hinges and metal parts to test, and with lab reports for each market. Roptan confirms the sample and bulk dates, and the minimum per model and colour, in the quote.

Inside Bangladesh we deliver to optical shops, chains, eye hospitals and distributors, sorted by model, size and colour code. Each delivery comes with the packing list, the frame and nickel reports and a VAT invoice (Mushak 6.3).

Buying acetate frames for export

For buyers abroad we ship by air from Hazrat Shahjalal International Airport, Dhaka, or FOB Chattogram for larger loads. Complete plastic frames usually go under HS 9003 11, parts and blanks under 9003 90. Papers include the certificate of origin, a REX statement for EU GSP or UK DCTS and the lab reports; the EU and UK want the importer's name and address on the product, its packaging or an accompanying document.

What we check for this order

Heat stability resultWe check the frame report includes dimensional stability at elevated temperature on this model.
Nickel on metal partsWe match every metal part and plating in the order to an EN 16128 nickel report.
Colour against the sealed sampleWe compare bulk frames with the sealed approved sample for each colour code.
Hinges, temples and sizeWe work the hinges, check temple fit and measure the marked size on frames drawn under ISO 2859-1.

Questions buyers ask

Are acetate frames safe for people with a nickel allergy?

Do not assume so. The front may be plastic, but hinges, screws and core wires are usually metal and some touch the skin. For the EU those parts must meet the REACH nickel limit, so ask for a nickel report on each one.

Why test an acetate frame at raised temperature?

Cellulose acetate is a thermoplastic, which softens when heated. A frame that distorts in heat no longer sits straight or holds its lenses, so ISO 12870 includes a dimensional stability test at elevated temperature. Ask for it per model.

Can one acetate frame be sold as both optical and sun?

Yes, but the papers differ. Glazed with prescription lenses it is a frame under ISO 12870 and a class I medical device in the EU. With plano tinted lenses it is sunglasses under ISO 12312-1 and PPE. Plan both reports from the start.

Who is responsible for EU compliance under my brand?

Usually you. Under Article 16 of Regulation (EU) 2017/745, a company selling a device under its own name takes on the manufacturer's duties, unless an agreement names the maker on the label. From 1 November 2028 newly produced frames also need a Master UDI-DI.

How soon will I hear back about eyewear and optical?

Within 48 hours of a complete requirement, with a price and a delivery date. A requirement is complete when it has the quantity, where it is needed and by when.
