Sourcing sunshine recorders from China

Zero duty on meteorological sunshine recorders

Read from the UK Trade Tariff on 1 October 2026, heading 9015 covers meteorological instruments alongside surveying, hydrological and geophysical equipment. The relevant instrument line is 9015 80 20 00; parts and accessories classified as such fall under 9015 90 00 00. The table distinguishes sunshine-recorder variants and dedicated assemblies sharing these tariff lines.

Both relevant lines carry 0% duty on goods from China, with no anti-dumping or countervailing measures and no suspensions listed in the supplied facts. The tariff attaches a DCMS Export Licence entry. Confirm any declaration or waiver requirement with your customs broker. Official guidance states that there are no licensing requirements for importing objects of cultural interest into Great Britain.

Confirm the commodity code using the recording method, intended use and details of any separately supplied components. Do not assume that loose recording cards or general-purpose mounting hardware share the instrument's code. For wider meteorological sourcing, see meteorological rain gauges.

Specify the sunshine-duration recording method

Specify glass-sphere card recording or electronic duration logging. For glass-sphere models, agree sphere material and diameter, optical quality, card-holder geometry, seasonal cards, latitude adjustment, mounting and levelling. For electronic models, agree the sunshine detection method, detection threshold, sampling interval, clock behaviour, output format and power supply. Ask the factory to identify how its instrument measures sunshine duration rather than simply reporting solar radiation.

Electronic models within scope need electromagnetic compatibility conformity; confirm the applicable CE or UKCA marking requirements with the relevant authority. General product safety rules apply to products intended for, or reasonably likely to be used by, consumers. Agree the applicable rules for the exact design and intended use. Include an assessment of concentrated sunlight, glass breakage and handling in the sample review.

Worked duty example

Illustrative example, not a quote: Illustrative order: 50 glass-sphere sunshine recorders under 9015 80 20 00, invoiced at £10,000 free on board, with £900 of freight and insurance to the UK. The customs value is £10,900. Duty at 0% is £0. Import VAT at 20% is charged on the customs value plus duty, £10,900, so it is £2,180. With no duty, the only import tax is the VAT, which a VAT-registered importer can usually reclaim. The import duty and VAT guide explains each step.

Inspection checklist

Sphere and holder: inspect for chips, bubbles and scratches; check that the sphere sits securely and focuses onto the intended recording-card position. Check that supplied seasonal cards fit without buckling or slipping.

Mounting and alignment: check the latitude adjustment, levelling provision, alignment instructions, fasteners and mounting dimensions against the approved sample. Confirm that adjustment locks hold their position.

Recording performance: compare sampled instruments with an agreed reference under shared exposure conditions. For card models, assess trace position and readability; for electronic models, check timestamps, missing data, duration totals and exported files against the agreed specification.

Arrival and documents: inspect cushioning, sphere restraint, glass damage, corrosion and moisture inside housings. Match model identification to calibration records and, for electronic models within scope, the conformity evidence and marking.

What goes wrong

A sphere that moves in its cradle, a distorted card holder or poorly fitting cards can produce displaced or unreadable traces. Incorrect alignment and loose latitude adjustment make comparisons unreliable. Electronic models can lose timestamps after a power interruption or export radiation readings when the buyer expected sunshine-duration totals.

Approve the recording method and sample output before ordering. Repeat functional checks after unpacking, retain results against each instrument's identification and agree how damaged spheres or failed recording assemblies will be replaced. Keep uncovered spheres away from loose combustible packing in sunlight.
